Electrical Installation Guide

a) Make sure all electrical breakers and switches are turned off before wiring the motor.
b) Make sure that the wiring voltage matches the motor voltage. If they do not match the
motor will be damaged.
c) It is the responsibility of the electrical installer to provide data plate operating voltage and
current to the pump by ensuring proper circuit and wire sizes.
WARNING
!
Failure to provide data plate voltage (within 10%) during operation will cause motor
overheating and will void the warranty.
d) Make sure all electrical connections are clean and tight.
e) Cut wires to the appropriate length so they don't overlap or touch when connected to the
terminal board.
f) Permanently ground the motor using the green ground terminal located on the inside of the
motor canopy or access plate. Use the correct wire size and type specified by local codes.
g) Make sure the ground wire is connected to an electrical service ground. Bond the motor
to the pool structure in accordance with the National Electrical Code. Use a solid No.8
AWG or larger copper conductor. Run a wire from the motor external bonding to the pool
bonding structure.
h) Connect the pump permanently to a dedicated circuit. No other lights, equipment, or
appliances can be used on the same circuit.
WARNING
!
Install the control switch or time clock well away from the pool pump, filter, and other
equipment. Should there be an equipment failure or loose fitting, access to the switch
away from the failed equipment is important.

START-UP

These pumps are designed to be used in pool recirculation systems with water at temperatures
above 4°C (39.2°F) and not exceeding 40°C (104°F). Please refer to the Waterco Warranty
Terms and Conditions booklet supplied with the pump.
!
Never run the pump without water. Running the pump dry for any length of time can
cause severe damage to the mechanical seal, pump and motor. Maintain the water level
in your pool half way up the skimmer opening. If the water level falls below the skimmer
opening, the pump will draw air through the skimmer. This will cause to pump to lose
prime and run dry.

Start-up procedure

a) Clear all piping of construction debris and verify that the piping has passed a proper
pressure test.
b) Check the filter and other equipment for proper installation, verifying all clamps and
connections are properly installed as per the manufacturer's instructions.
c) Open any shut off valves on the suction and discharge lines.
d) Open the filter pressure relief valve and release all pressure from the system.
e) If the pump is located below the water level of the pool, opening the pressure relief valve
will fill the pump with water.
f) If the pump is located above the pool water level, remove the lid from the strainer pot and
fill with water before starting the pump.
g) Check to see that the lid O-ring and seat areas are clean and lubricated. Debris in the
sealing area can cause air to leak into the system and make it difficult to prime the pump.
Use a silicone based lubricant.
h) Close/tighten the lid to make an airtight seal.
i) Turn on the pump.
j) Bleed air from the filter until a steady stream of water comes out. Close the air relief valve.
k) If the pump does not prime and all instructions to this point have been followed, check
for suction leaks and repeat steps (b) through (j).
WARNING
!
High suction lift or long suction line will require additional time to prime and can severely
affect the performance of the pump.
