Initial Startup

Do not operate pump until it has been primed as water acts to cool and lubricate the seal. For pumps without strainer bodies
and locater above water, close suction line valve and fill pump with water in order to prime. For pumps with strainer bodies and
located above water, prime by removing strainer cover and filling strainer body with water. Pumps located below water level will
self prime if all piping is also below water level. After pump has been primed, energize motor and open all suction and discharge
line valves. It may take some time for pump to remove air from suction lines. If no flow is observed in five minutes, stop the motor
and re-prime. If the pump fails to operate, check for air leaks. Refer to Trouble Shooting section.
After about ten minutes of operation, check the return fittings for air bubbles. A continuous flow of air indicates leaks in suction
line. Locate and correct any leaks immediately.
Controlling The Output
Keep the gate valve in the suction line fully open during operation. Should it be necessary to control the output, use a valve in the
return line.
CAUTION: Do not re-tighten strainer Ring-Lok during operation.
CAUTION: Do not operate pump with closed suction or discharge valves.

Specifications

Two-Speed Pumps
Two-speed models are recommended in a swimming pool when high speed is needed for maximum filtration at peak periods and
whenever turbidity levels are high. At other times, switch to low speed. For backwashing and vacuuming, high speed is required.
In spas and hot tubs, use high speed to attain full performance in the hydro-therapy mode. At other times, such as filter/heat cycle
mode, use low speed. Low speed provides sufficient flow to activate most spa heaters and provides sufficient flow for filtration.
In jetted tubs, use high speed to attain full performance in the hydro-therapy mode and use low speed mode to prime. The below
picture shows how to switch between the high speed and low speed.
