SECTION I. GENERALINFORMATION
A. Wiring.
WARNING
Risk of electrical shock or electrocution.
This pool pump must be installed by a licensed or certified electrician or a qualified pool serviceman in accordance with the National Electrical Code and all applicable local codes and ordinances. Improper installation will create an electrical hazard which could result in death or serious injury to pool users, installers, or others due to electrical shock, and may also cause damage to property.
Always disconnect power to the pool pump at the circuit breaker before servicing the pump. Failure to do so could result in death or serious injury to serviceman, pool users or others due to electric shock.
1. Make sure all electrical breakers and switches are turned off before wiring motor.
2.Make sure that the wiring voltage matches the motor voltage (230v or 115v). If they do not match the motor will burn up.
3.Choose a wire size from the Chart 1. When in doubt use a heavier gauge (larger diameter) wire. Heavier gauge will allow the motor to run cooler and more efficient.
4.Make sure all electrical connections are clean and tight.
5.Cut wires to the appropriate length so they don’t overlap or touch when connected to the terminal board.
6.Permanently ground the motor using the green ground terminal located on the inside of the motor canopy or access plate, see Figure 1. Use the correct wire size and type specified by National Electrical Code. Make sure the ground wire is connected to an electrical serviceground.

CAUTION
The polished and lapped faces of the seal could be damaged if not handled with care.
CAUTION
In mild climate area, when temporary freezing conditions may occur, run your filtering equipment all night to prevent freezing.
SECTION IV. RESTARTINSTRUCTIONS
A.If pump is installed below the water level of the pool, close return and suction lines prior to opening hair and lint pot on pump. Make sure to re-open valves prior to operating.
CAUTION
DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump will start leaking. If this occurs, the damaged seal must be replaced. ALWAYS maintain proper water level in your pool (half way up skimmer opening). If the water level falls below the skimmer opening, the pump will draw air through the skimmer, losing the prime and causing the pump to run dry, resulting in a damaged seal.
NOTE
Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and seal.
