A WARNING – Risk of Electric Shock. Allelectrical 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.
A 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.
A 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.
A 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.

Product Dimensions
Energy Efficiency Overview
The energy consumed by a pool pump is measured in terms of Watts (W) or Kilowatts (kW). The 1.65 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.
On the following page 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 allother 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.
Installation
ARNING – This product should be installed and serviced only by a qualified professional.
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.
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
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 1.65 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.
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.
Plumbing

2.
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.
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.
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.
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.
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.
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 willconnect 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.
Wiring
AWARNING – Allelectrical wiring MUST conform to local codes, regulations, and National Electric Code (NEC)
1.
2.
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.
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..
Remote Control Wiring/Operation
The 1.65 THP VS pump family can be controlled in a wide variety of ways as described below:
1. They can operate by themselves in Stand-Alone Mode using their built-in programmable timers.
2. They can also be controlled from third party controls (i.e. another manufacturer’s control) and Hayward controls that are not software compatible using relay
contacts. See page 13 for more information regarding connecting this pump and third party/non-software compatible Hayward controls.
3. They can communicate with and be controlled by Hayward pool and spa controls. See page 14 for more information regarding connecting this pump and
Hayward pool and spa controls.
Digital Control Interface Orientation
The Digital Control Interface can be rotated to any of four desired positions after installation by loosening the two screws securing the user interface to the motor
drive, lifting the user interface and rotating it to the desired position, and tightening the two screws in the new position.
