OPERA TION

Hazardous suction. Can trap hair or body parts, causing severe

injury or death by drowning. Do not block pump or strainer

Hazardous

suction with body. Small children using pool must ALWAYS

suction.

have close adult supervision!

Do not run pump against closed discharge valve. To do so can boil

water in pump body, and can cause severe burns to people working on pump.

Fire and burn hazard. Modern motors run at high temperatures.

To reduce the risk of fire, do not allow leaves, debris, or foreign matter to col-

lect around the pump motor. To avoid burns when handling the motor, let it

cool for 20 minutes before trying to work on it. An automatic internal cutoff

switch protets the motor from heat damage during operation.

NEVER run pump dry. Running pump dry may damage seals,

causing leakage and flooding. Fill pump with water before starting motor.

Before removing strainer cover:

1. STOP PUMP before proceeding.

2. CLOSE ISOLATION VALVES in suction and discharge pipes.

3. RELEASE ALL PRESSURE from pump and piping system.

After pressure test, release all pressure before removing strainer cover!

NOTICE: Provide adequate ventilation. Ambient air temperature should be

104°F (40°C) or less, but above freezing at all times.

NOTICE: To prevent corrosion damage, store pool chemicals in another room

away from pump.

Priming Pump

Hazardous Pressure! Before removing strainer cover, remove

vent plug in cover and release all pressure from system.

Open suction/discharge valves. In a flooded suction system, pump will prime.

If pump is not in a flooded suction system, remove strainer cover; fill strainer

and pump with water.

If necessary, use a wrench on flats when removing wing nuts.

When installing cover, clean O-Ring sealing surface on strainer body, and

lubricate with petroleum jelly as follows:

A. O-Ring and Sealing surfaces of strainer cover and body;

B. Threads and faces of wing nuts.

This will prevent corrosion, improve seal, and ease maintenance.

Center strainer cover when installing it (especially when pressure testing).

Hand tighten wing nuts. When tightening, alternate back and forth between

nuts to compress O-Ring evenly.

Maximum wing nut torque is 25 ft.-lbs. (3.5 kg.-m).

Start pump; it should prime now. Priming time will depend on vertical length

of suction lift (10'/3m maximum) and horizontal length of suction pipe.

Priming for the A142C through A145C3 series pumps has been tested to 10 ft.

elevation above water level. Priming time using 6" diameter suction pipe is

approximately 9 minutes, at less than 1,000 ft. above sea level with baromet-

ric reading at 30" Hg. Priming times will vary with atmospheric pressure, ele-

vation above sea level, and pipe diameter.
