ATTENTION INSTALLER - THIS MANUAL CONTAINS IMPORTANT INFORMATION ABOUT THE INSTALLATION,
OPERATION, AND SAFE USE OF THIS VARIABLE SPEED PUMP THAT MUST BE FURNISHED TO THE END USER OF THIS
PRODUCT. FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS COULD RESULT IN SERIOUS INJURY.
WARNING – To reduce risk of injury, do not permit children to use or climb on this product. Closely
supervise children at all times. Components such as the filtration system, pumps, and heaters must be positioned
to prevent children from using them as a means of access to the pool.
CAUTION – This pump is intended for use on permanently installed swimming pools and may also be used
with hot tubs and spas if so marked. Do NOT use with storable pools. A permanently installed pool is constructed in
or on the ground or in a building such that it cannot be readily disassembled for storage. A storable pool is
constructed so that it is capable of being readily disassembled for storage and reassembled to its original integrity.
Though this product is designed for outdoor use, it is strongly advised to protect the electrical components from the
weather. Select a well-drained area, one that will not flood when it rains. It requires free circulation of air for
cooling. Do not install in a damp or non-ventilated location. If installed within an outer enclosure or beneath the
skirt of a hot tub or spa, adequate ventilation and free circulation of air must be provided to prevent overheating of
the motor.

WARNING – Pool and spa components (seals, gaskets, etc.) have a finite life. All components should be
inspected frequently and replaced at least every ten years, or if found to be damaged, broken, cracked, missing, or
not securely attached.
WARNING – Risk of Electric Shock. All electrical wiring MUST be in conformance with applicable local
codes, regulations, and the National Electric Code (NEC). Hazardous voltage can shock, burn, and cause death or
serious property damage. To reduce the risk of electric shock, do NOT use an extension cord to connect unit to
electric supply. Provide a properly located electrical receptacle. Before working on pump or motor, turn off power
supply to the pump.
WARNING – To reduce the risk of electric shock replace damaged wiring immediately. Locate conduit to
prevent abuse from lawn mowers, hedge trimmers and other equipment.
WARNING – Risk of Electric Shock. In accordance with the National Electric Code (NEC), connect only to a
branch circuit protected by a ground-fault circuit-interrupter (GFCI). Contact a qualified electrician if you cannot
verify that the circuit is protected by a GFCI. The unit must be connected only to a supply circuit that is protected by
a ground-fault circuit-interrupter (GFCI). Such a GFCI should be provided by the installer and should be tested on a
routine basis. To test the GFCI, push the test circuit button. The GFCI should interrupt power. Push the reset button.
Power should be restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the GFCI interrupts
power to the pump without the test button being pushed, a ground current is flowing, indicating the possibility of an
electric shock. Do not use this pump. Disconnect the pump and have the problem corrected by a qualified service
representative before using.
WARNING – Failure to bond pump to pool structure will increase risk for electrocution and could result in
injury or death. To reduce the risk of electric shock, see installation instructions and consult a professional
electrician on how to bond pump. Also, contact a licensed electrician for information on local electrical codes for
bonding requirements.
Notes to electrician: Use a solid copper conductor, size 8 or larger. Run a continuous wire from external bonding lug
to reinforcing rod or mesh. Connect a No. 8 AWG (8.4 mm2) [No. 6 AWG (13.3 mm2) for Canada] solid copper bonding
wire to the pressure wire connector provided on the pump housing and to all metal parts of swimming pool, spa, or
hot tub, and to all electrical equipment, metal piping (except gas piping), and conduit within 5 ft. (1.5 m) of inside
walls of swimming pool, spa, or hot tub. IMPORTANT - Reference NEC codes for all wiring standards including, but
not limited to, grounding, bonding and other general wiring procedures.
WARNING – Suction Entrapment Hazard. Suction in suction outlets and/or suction outlet covers, which are
damaged, broken, cracked, missing, or unsecured cause severe injury and/or death due to the following entrapment
hazards (symbols complements of APSP):
Hair Entrapment - Hair can become entangled in suction outlet cover.
Limb Entrapment - A limb inserted into an opening of a suction outlet sump or suction outlet cover that is damaged,
broken, cracked, missing, or not securely attached can result in a mechanical bind or swelling of the limb.
Body Suction Entrapment - A differential pressure applied to a large portion of the body or limbs can result in an
entrapment.
Evisceration/ Disembowelment - A negative pressure applied directly to the intestines through an unprotected
suction outlet sump or suction outlet cover which is damaged, broken, cracked, missing, or unsecured can result in
evisceration/disembowelment.

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
Page 6 of 36 1.85 THP VS Pump Family IS3202VSP3 Rev-A
WARNING – To Reduce the risk of Entrapment Hazards:
When outlets are small enough to be blocked by a person, a minimum of two functioning suction outlets per
pump must be installed. Suction outlets in the same plane (i.e. floor or wall), must be installed a minimum of
three feet (3’) [0.91 meter] apart, as measured from near point to near point.
Dual suction fittings shall be placed in such locations and distances to avoid “dual blockage” by a user.
Dual suction fittings shall not be located on seating areas or on the backrest for such seating areas.
The maximum system flow rate shall not exceed the values shown in the “Pipe Sizing Chart” found in section
4.3 below.
Never use pool or spa if any suction outlet component is damaged, broken, cracked, missing, or not securely
attached.
Replace damaged, broken, cracked, missing, or not securely attached suction outlet components
immediately.
In addition to two or more suction outlets per pump installed in accordance with latest APSP standards and
CPSC guidelines, follow all national, state, and local codes applicable.
Installation of a vacuum release or vent system, which relieves entrapping suction, is recommended.
WARNING – Hazardous Pressure. Pool and spa water circulation systems operate under hazardous
pressure during start-up, normal operation, and after pump shut-off. Stand clear of circulation system equipment
during pump start-up. Failure to follow safety and operation instructions could result in violent separation of the
pump housing and cover due to pressure in the system, which could cause property damage, severe personal injury,
or death. Before servicing pool and spa water circulation system, all system and pump controls must be in off
position and filter manual air relief valve must be in open position. Before starting pump, all system valves must be
set in a position to allow system water to return back to the pool. Do not change filter control valve position while
pump is running. Before starting pump, fully open filter manual air relief valve. Do not close filter manual air relief
valve until a steady stream of water (not air or air and water mix) is discharged from the valve. All suction and
discharge valves MUST be OPEN when starting the circulation system. Failure to do so could result in severe
personal injury and/or property damage.
WARNING – Separation Hazard. Failure to follow safety and operation instructions could result in violent
separation of pump components. Strainer cover must be properly secured to pump housing with strainer cover lock
ring. Before servicing pool and spa circulation system, all system and pump controls must be in off position and
filter manual air relief valve must be in open position. Do not operate pool and spa circulation system if a system
component is not assembled properly, damaged, or missing. Do not operate pool and spa circulation system unless
filter manual air relief valve body is in locked position in filter upper body. All suction and discharge valves MUST be
OPEN when starting the circulation system. Failure to do so could result in severe personal injury and/or property
damage.
WARNING – Never operate the circulation system at more than 50 PSI maximum.
WARNING – Fire and burn hazard. Motors operate at high temperatures and if they are not properly
isolated from any flammable structures or foreign debris they can cause fires, which may cause severe personal
injury or death. It is also necessary to allow the motor to cool for at least 20 minutes prior to maintenance to
minimize the risk for burns.
WARNING – Failure to install according to defined instructions may result in severe personal injury or
death.

3. Energy Efficiency Overview
The energy consumed by a pool pump is measured in terms of Watts (W) or Kilowatts (kW). The 1.85 THP variable speed
pump family displays power consumption in Watts. Given this information, you can determine the cost of operating the
pump:
Power consumption of pump X Cost of electricity = Cost of Pump Operation per Hour
Example: Hayward variable speed pump operating at 300 W. Cost of electricity = $0.10 per kWh
Convert Watts to Kilowatts: 300 W = 0.3 kW
0.3 kW X $0.10/kWh = $0.03 per hour
Note the power consumption is greatly affected by the speed of the pump. Lowering the speed of the pump can
drastically reduce the power that is consumed. Below are some of the major benefits of running the pump at lower
speeds.
Benefits of running at low speeds
Save electricity and money
Improved filtration – the filter can often remove smaller particles when the water moves slower
Quiet operation
Reduced Total Dynamic Head – less stress on equipment (e.g. filter) which can lengthen equipment life
When determining the speed(s) to operate your pump, you must also take into account the minimum requirements for
proper sanitation and equipment/water feature functionality.
It is recommended you filter (“turnover”) all the water in the pool at least once every 24 hours. Check with local
requirements for the minimum turnover rate. Running the pump at a lower speed may require running the pump for a
longer period of time in order to meet the turnover requirements for proper sanitation.
Equipment such as heaters, skimmers, and chlorinators require minimum flows to operate correctly. Refer to individual
equipment manuals for specific flow requirements.
After setting the pump speed(s), it is recommended you check that all other equipment/water features are functioning as
intended. For example, when running at a low speed for daily filtration, verify water is adequately flowing over the
skimmer weirs. Operate the pump at higher speeds for the shorter periods of time needed to operate a heater, water
feature, etc.
4. Installation and Wiring
WARNING – This product should be installed and serviced only by a qualified professional.
4.1. Pump Location
Locate pump as close to pool as practical and run suction lines as direct as possible to reduce friction loss. Suction
lines should have continuous slope upward from lowest point in line. Joints must be tight (but not over-tightened).
Suction line diameter must equal or be larger than the discharge line diameter.
Though the pump is designed for outdoor use, it is advised to place pump and filter in the
shade to shield them from continuous direct heat. Select a well-drained area that will not
flood when it rains. Do NOT install pump and filter in a damp or non-ventilated location.
Keep motor clean. Pump motors require free circulation of air for cooling.
USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
Page 9 of 36 1.85 THP VS Pump Family IS3202VSP3 Rev-A
4.2. Pump Mounting
Install pump on a level concrete slab or other rigid base to meet all local and national codes. Secure pump to base
with screws or bolts to further reduce vibration and stress on pipe or hose joints. The base must be level, rigid, and
vibration free.
Pump mount must:
Allow pump inlet height to be as close to water level as possible.
Allow use of short, direct suction pipe (to reduce friction losses).
Allow for valves in suction and discharge piping.
Be protected from excess moisture and flooding.
Allow adequate access for servicing pump and piping.
4.3. Pipe Sizing Chart
MAXIMUM RECOMMENDED SYSTEM FLOW RATE BY PIPE SIZE
Pipe Size
in. [mm]
Maximum Flow Rate
GPM [LPM]
Minimum Straight Pipe
Length “L” in. [mm] *
1 ½” [50] 45 [170] 7 ½” [190]
2” [63] 80 [300] 10” [254]
2 ½” [75] 110 [415] 12 ½” [317]
3” [90] 160 [600] 15” [381]
Note: It is recommended that a minimum length of straight piping (shown as “L” in above diagram), equivalent to 5
pipe size diameters, be used between the pump suction inlet and any plumbing fittings (elbows, valves, etc.).
When installing the 1.85 THP VS pump family, care should be taken to ensure proper pipe and equipment sizing to
handle the maximum flow required. It is recommended to set the maximum speed in order to not exceed the
maximum flow rate. See section 6.6 item #7.
WARNING – Hazardous Pressure. Pumps, filters, and other equipment/ components of a swimming pool
filtration system operate under pressure. Incorrectly installed and/or improperly tested filtration equipment and/or
components may fail resulting in severe personal injury or death.
4.4. Plumbing
1. Use PTFE tape to seal threaded connections on molded plastic components. All plastic fittings must be new or
thoroughly cleaned before use. NOTE - Do NOT use Plumber’s Pipe Dope as it may cause cracking of the plastic
components. When applying PTFE tape to plastic threads, wrap the entire threaded portion of the male fitting
with one to two layers of tape. Wind the tape clockwise as you face the open end of the fitting, beginning at the
end of the fitting. The pump suction and outlet ports have molded-in thread stops. Do NOT attempt to force
hose connector fitting past this stop. It is only necessary to tighten fittings enough to prevent leakage. Tighten
fitting by hand and then use a tool to engage fitting an additional 1 ½ turns. Use care when using PTFE tape as
friction is reduced considerably; do NOT over-tighten fitting or you may cause damage. If leaks occur, remove
connector, clean off old PTFE tape, re-wrap with one to two additional layers of PTFE tape, and re-install
connector.
2. Fittings (elbows, tees, valves, etc.) restrict flow. For better efficiency, use the fewest possible fittings. Avoid
fittings that could cause an air trap. Pool and spa fittings MUST conform to the International Association of
Plumbing and Mechanical Officials (IAPMO) standards.
USE ONLY HAYWARD GENUINE REPLACEMENT PARTS

4.5. Electrical
WARNING – All electrical wiring MUST conform to local codes, regulations, and the National Electric Code
(NEC).
WARNING – Ground and bond pump before connecting to electrical power supply. Failure to ground and
bond pump can cause serious or fatal electrical shock hazard. Do NOT ground to a gas supply line. To avoid
dangerous or fatal electrical shock, turn OFF power to pump before working on electrical connections. Fire Hazard -
match supply voltage to pump nameplate voltage. Insure that the electrical supply available agrees with the pump’s
voltage, phase, and cycle, and that the wire size is adequate for the amps rating and distance from the power
source. Use copper conductors only.
4.6. Electrical Specs
Refer to motor nameplate for voltage and current ratings. Use copper conductors only. For indoor & outdoor use.
Connect pump to a 15 amp branch circuit in accordance with local codes, regulations, and the National Electric Code
(NEC). A disconnecting means located at least 5 ft. from the inside wall of the pool, spa, or hot tub must be
provided.
4.7. Voltage
Voltage at pump MUST NOT be more than 10% above or below nameplate rated voltage, or components may
overheat, causing overload tripping and reduced component life. If voltage is less than 90% or more than 110% of
rated voltage when pump is running at full load, consult the power company.
4.8. Grounding and Bonding
1. Install, ground, bond, and wire pump in accordance with local or national electrical code requirements.
2. Permanently ground pump. Use green ground terminal provided under access plate; use size and type wire
required by code. Connect ground terminal to electrical service ground.
3. Bond pump to pool structure. Bonding will connect all metal parts within and around the pool with a continuous
wire. Bonding reduces the risk of a current passing between bonded metal objects, which could potentially
cause electrical shock if grounded or shorted. Reference NEC codes for all wiring standards including, but not
limited to, grounding, bonding and general wiring procedures.
4. Use a solid copper conductor, size 8 or larger. Run wire from external bonding lug to reinforcing rod or mesh.
Connect a No. 8 AWG (8.4 mm2) [No. 6 AWG (13.3 mm2) for Canada] solid copper bonding wire to the pressure
wire connector provided on the motor housing and to all metal parts of swimming pool, spa, or hot tub, and to
all electrical equipment, metal piping (except gas piping), and conduit within 5 ft. (1.5 m) of inside walls of
swimming pool, spa, or hot tub.
4.9. Wiring
WARNING – All electrical wiring MUST conform to local codes, regulations, and National Electric Code (NEC)
1. Pump MUST be permanently connected to circuit. If other lights or appliances are also on the same circuit, be
sure to add their amp loads before calculating wire and circuit breaker sizes. Use the circuit breaker as the
master On-Off switch.
2. If this VS pump is being used to replace an existing pump that was controlled by a separate mechanical time
clock, it should be connected directly to the line power supply, bypassing the time clock. The time clock can
then be used to power other equipment (such as a heater, heat pump, or booster pump) that requires the filter
pump to be operating when used. If the time clock is used in this manner, it should be set to power the
equipment during a time cycle when the VS pump is operating at an appropriate flow rate to operate the other
equipment, as defined by the timers set in the Timer Menu. See section 6.7

3. INP2 connected: pump runs 3450 rpm for 8 minutes, then 2600 rpm
4. INP3 connected: pump runs 3450 rpm
See section 5.4 for details regarding input connections (relays would not be used when connecting inputs to set
comm loss behavior; use short jumpers in this case). Note: Prior to drive comm revision 10.10, pump response
was as follows: no inputs connected – pump runs 3450 rpm for 8 minutes then 1725 rpm; INP1 connected – pump
runs 3450 rpm for 8 minutes then 2600 rpm; INP2 connected – pump runs 3450; INP3 connected – pump remains
stopped. Jumpers, if used to set desired behavior in the event of communication loss, need to be installed at
initial pump installation.
When communicating with OmniLogic, the HUA (Hayward Unique Address) is used for communication. For all Hayward
controls other than OmniLogic, the pump address must be set using the DIP switches on the drive PCB. To determine
which address should be used, consult the appropriate Hayward pool control installation manual, or visit our website
at www.haywardpool.com. Pump addresses are set according to the table on the following page.

This pump can be controlled from third party pool controls as well as Hayward controls that are not software
compatible using relay contacts to select the speeds set in the Timer Menu (see section 6.7). In addition to this
section you may also consult the applicable pool control installation manual for electrical connection details. Once
installed, Remote Control Mode must be set to Relay Control in the pump Configuration Menu (see section 6.6).
Preset Speeds 1-4 and Quick Clean are disabled when the pump is remotely controlled. When inputs INP1-3 are
activated via the pool control relay contacts, timer speeds 1-8 are selected according to the following table (see
section 6.7):
Timer

The number of speeds available depends on the number of auxiliary relays used as noted below:
1. Filter pump relay plus 1 auxiliary relays allows control of 2 speeds
2. Filter pump relay plus 2 auxiliary relays allows control of 4 speeds
3. Filter pump relay plus 3 auxiliary relays allows control of 8 speeds
5.4. Wall Mounted Digital Control Interface Wiring (Optional)
Figure 5.4-1
Connection wire must be rated for a minimum of 300V, and may be up to 500 feet in length. Use removable
4-position terminal block connectors for wiring connection to interface and motor drive PCB’s taking care to note the
wire colors and corresponding numbers next to the connectors. Terminal block must be installed with screws facing
up to ensure proper connection. DIP switch #1 must be “ON”.

5.5. Remote Stop Switch Wiring (Optional)
Figure 5.5-1
Connection wire must be rated for a minimum of 300V. Switch must be latching type; pump is stopped when circuit is
closed. Inputs are rated to accept a low voltage supply of 18-30 VAC, 9-30 VDC, 50/60 Hz. The “+12V” and “COM”
terminals may be used as a low voltage supply, however these terminals also supply power to the user interface , so
care must be taken when connecting to these terminals to ensure proper operation of user interface. If the “+12V” and
“COM” terminals are used, DIP switch #1 must be “ON”.
6. Startup & Operation
6.1. Prior to Start-Up
If it is necessary to perform a water pressure test prior to initial use to ensure plumbing system is functioning
properly, then the following criteria should be maintained for this test:
1. Have a professional perform this test.
2. Ensure all Hayward pump and system components are removed from system prior to performing test.
WARNING – If circulation equipment must remain in the plumbing system during water pressure test, do
not apply more than 10 psi pressure to the system. Be sure water pressure has been released, using the filter
manual air relief valve, before removing pump strainer cover.
WARNING – All suction and discharge valves MUST be OPEN, as well as filter air relief valve (if available) on
filter, when starting the circulating pump system. Failure to do so could result in severe personal injury.
USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
Page 19 of 36 1.85 THP VS Pump Family IS3202VSP3 Rev-A
6.2. Starting/Priming the Pump
Refer to item #10 in section 6.6 for priming time selection.
Fill strainer housing with water to suction pipe level. If water leakage occurs from anywhere on the pump or filter, DO
NOT start the pump. If no leakage occurs, stand at least 10 feet from pump and/or filter and proceed with starting
the pump.
WARNING – Return to filter to close filter manual air relief valve when a steady stream of water (not air or air
and water) is discharged from valve. Failure to do so could result in severe personal injury.
ATTENTION – NEVER OPERATE THE PUMP WITHOUT WATER. Water acts as a coolant and lubricant for the
mechanical shaft seal. NEVER run pump dry. Running pump dry may damage seals, causing leakage, flooding, and
voids warranty. Fill strainer housing with water before starting motor.
ATTENTION – Do NOT add chemicals to pool/spa system directly in front of pump suction. Adding
undiluted chemicals may damage pump and voids warranty.
ATTENTION – Before removing strainer cover:
1. STOP PUMP before proceeding.
2. CLOSE VALVES in suction and outlet pipes.
3. RELEASE ALL PRESSURE from pump and piping system using filter manual air relief valve. See filter owner’s
manual for more details.
4. Remove strainer cover and fill strainer housing with water.
5. Clean and lubricate strainer cover O-ring with "Jack's 327" if necessary.
6. Replace strainer cover on strainer housing.
7. OPEN VALVES in suction and outlet pipes.
Note: Tighten strainer cover lock ring by hand only (no wrenches).
Turn on power and wait for pump to prime, which can take up to ten (10) minutes. Priming time will depend on
vertical length of suction lift and horizontal length of suction pipe. If pump does NOT prime within 10 minutes, stop
motor and determine cause. Be sure all suction and discharge valves are open when pump is running. See
Troubleshooting Guide.

8. Storage / Winterization
WARNING – Separation Hazard. Do not purge the system with compressed air. Purging the system with
compressed air can cause components to explode, with risk of severe injury or death to anyone nearby. Use only a
low pressure (below 5 PSI), high volume blower when air purging the pump, filter, or piping.
ATTENTION – Allowing the pump to freeze with water in it will void the warranty.
ATTENTION – Use ONLY propylene glycol as antifreeze in your pool/spa system. Propylene glycol is non-
toxic and will not damage plastic system components; other anti-freezes are highly toxic and may damage plastic
components in the system.
Drain all water from pump and piping when expecting freezing temperatures or when storing pump for a long time
(see instructions below). Gravity drain system as far as possible.
Keep motor dry and covered during storage. To avoid condensation/corrosion problems, do NOT cover or wrap pump
with plastic film or bags.
8.1. Storing Pump For Winterization
WARNING – To avoid dangerous or fatal electrical shock hazard, turn OFF power to motor before draining
pump. Failure to disconnect power may result in serious personal injury or death.
1. Drain water level below all inlets to the pool.
2. Remove drain plugs and strainer cover from strainer housing. (See “Parts Diagram” in section 10.1 of this
manual for pump component locations.)
3. Disconnect pump from mounting pad, wiring (after power has been turned OFF), and piping.
4. Once the pump is fully drained of water, re-install the strainer cover and drain plugs. Store pump in a dry area.
9. Shaft Seal Change Instructions
IMPORTANT SAFETY INSTRUCTIONS
PLEASE READ AND FOLLOW ALL INSTRUCTIONS

11. Troubleshooting
11.1. General Problems
Motor Will NOT Start:
1. Make sure the terminal board connections agree with the wiring diagram on the pump data plate label.
2. Be sure the pump is wired for the available field supply voltage.
3. Check for and correct any improper or loose wiring connections; open switches or relays; tripped circuit
breakers, or blown fuses.
4. Manually check the rotation of the motor shaft for free movement and lack of obstruction. Correct if
necessary.
Motor Shuts OFF:
1. Check for low voltage or power drop at the motor (frequently caused by undersized wiring). Contact a
qualified professional to verify the electrical connections.
Motor Hums, But Does NOT Start:
1. Impeller jammed with debris. Have a qualified repair professional open the pump and remove the debris.
Pump Won't Prime:
1. Empty pump/strainer housing. Make sure the pump/strainer housing is filled with water and the cover o-
ring is clean. Ensure the o-ring is properly seated in the cover o-ring groove. Ensure the o-ring sealing
surface is lubricated with “Jack’s 327” and that the strainer cover is locked firmly in position. Lubricant will
help to create a tighter seal.
2. Loose connections on the suction side. Tighten the pipe/union connections.
Note: Any self-priming pump will not prime if there are suction air leaks. Leaks will result in bubbles
emanating from the return fittings on the pool wall.
3. Leaking O-ring or packing glands on valves. Tighten, repair, or replace the valves.
4. Strainer basket or skimmer basket loaded with debris. Remove the strainer housing cover or the skimmer
cover. Clean the basket, and refill the strainer housing with water. Tighten the cover.
5. Suction side clogged. Contact a qualified repair professional. You should have 5” - 6” of vacuum at the
strainer cover (your pool dealer can confirm this with a vacuum gauge). You may be able to check by
removing the skimmer basket and holding an object over the bottom port with the skimmer full and the
pump running. If no suction is felt, check for line blockage.
a. If the pump develops a vacuum, check for a blocked suction line or a dirty strainer basket. An air
leak in the suction piping may be the cause.
b. If the pump does not develop a vacuum and the pump has sufficient “priming water”:
i. Re-check the strainer housing cover and all threaded connections for suction leaks. Check
if all system hose clamps are tight.
ii. Check voltage to ensure that the motor is rotating at full rpm’s.
iii. Open the housing cover and check for clogging or obstruction in suction. Check the
impeller for debris.
iv. Remove and replace the shaft seal only if it is leaking.
Low Flow – Generally:
1. Clogged or restricted strainer or suction line. Contact a qualified repair professional.
2. Undersized pool piping. Correct the piping size.
3. Plugged or restricted discharge line of filter, valve partially closed (high gauge reading). Sand filters –
backwash as per manufacturer’s instructions; D.E. filters – backwash as per manufacturer’s instructions;
Cartridge filters – clean or replace the cartridge.
4. Air leak in suction (bubbles issuing from return fittings). Re-tighten the suction and discharge connections
using PTFE tape. Inspect other plumbing connections, and tighten as required.
5. Plugged, restricted, or damaged impeller. Replace the impeller including a new seal assembly.

Noisy Pump:
1. Air leak in suction piping, cavitations caused by restricted or undersized suction line or leak at any joint, low
water level in pool, and unrestricted discharge return lines. Correct the suction condition or throttle return
lines, if practical. Holding your hand over the return fitting will sometimes prove this, or by putting in a
smaller eyeball fitting.
2. Vibration due to improper mounting, etc. Mount the pump on a level surface and secure the pump to the
equipment pad.
3. Foreign matter in the pump housing. Loose stones/debris hitting the impeller could be the cause. Clean the
pump housing.
4. Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal
damage, which will allow chlorinated water to seep into bearings wiping out the grease causing bearing to
whine. All seal leaks should be replaced at once.
Interference With Home Automation/Power Line Communication Equipment:
1. Make sure the terminal board connections agree with the wiring diagram on the pump data plate label.
2. Check for and correct any improper or loose wiring connections.
3. Install noise filter (from home automation/power line communication equipment vendor) to prevent
equipment interference.
11.2. Check System Messages
Code Troubleshooting
