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

or death.

Do not block suction.

OPERATION

NOTICE: NEVER run pump dry. Running pump dry may damage seals, causing leakage and flooding. Fill pump with water before starting motor.

Before removing trap cover:

1.STOP PUMP before proceeding.

2.CLOSE GATE VALVES in suction and discharge pipes.

3.RELEASE ALL PRESSURE from pump and piping system.

If pump is being pressure tested, be sure pressure

has been released before removing trap cover.

Do not block pump suc-

tion. To do so with body may cause severe or

fatal injury. Small children

using pool must ALWAYS have close adult supervision.

Fire and burn

hazard. Modern motors run at high temperatures. To reduce the risk of fire, do not allow leaves, debris, or foreign mat- ter to collect 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 in-

ternal cutoff switch protects the motor from heat damage during operation.

NOTICE: Maximum ambient temperature for motor oper- ation must not exceed maximum ambient temperature on motor nameplate.

Priming Pump

Release all pressure from filter, pump, and piping system; see the filter owner’s manual.

In a flooded suction system (water source higher than pump), pump will prime itself when suction and dis- charge valves are opened.

If pump is not in a flooded suction system, unscrew and remove trap cover; fill trap and pump with water.

Clean and inspect O-Ring; reinstall on trap groove.

Do not lubricate the trap cover O-Ring. The original equipment O-Ring contains a permanent internal lubri- cant.

NOTICE: If you replace the O-Ring with a non-internally lubricated O-Ring, you may need to apply a silicone based lubricant.

Replace trap cover on trap; turn clockwise to tighten cover.

NOTICE: Tighten trap cover handle ring by hand only (no wrenches)! See Figure 1, Page 4.

Pump should prime now. Priming time will depend on vertical length of suction lift and horizontal length of suc- tion piping.

If pump does not prime, make sure that all valves are open, suction pipe end is under water, pump is not trying to lift water more than 10' (3m), and that there are no leaks in suction pipe. See Troubleshooting Guide, Page 12.

Routine Maintenance

The only routine maintenance needed is inspection/cleaning of trap basket. Debris or trash that collects in basket will choke off water flow through the pump. Follow instructions below to clean trap:

1.Stop pump, close valves in suction and discharge, and release all pressure from system before proceeding.

2.Remove trap cover handle ring (turn counterclock- wise). If necessary, tap handles gently with a rubber mallet.

3.Remove strainer basket and clean. Be sure all holes in basket are clear, flush basket with water and replace in trap with large opening at pipe connection port (be- tween ribs provided). If basket is replaced backwards cover will not fit on trap body.

4.Clean and inspect lid O-Ring; reinstall on trap groove.

5.Clean O-Ring groove on trap body and replace cover and handle ring. To help keep cover from sticking, tighten hand tight only.

6.Prime pump (see priming instructions).

Storage/Winterizing

NOTICE: Allowing pump to freeze will damage pump and void warranty!

NOTICE: Do not use anti-freeze solutions (except propy- lene glycol) in your pool/spa system. Propylene glycol, “RV antifreeze”, is non-toxic and will not damage plastic system components; other anti-freezes are highly toxic and may damage plastic components in the system.

Drain all water from pump and piping when expecting freezing temperatures or when storing pump for a long time (see instructions below).

Keep motor dry and covered during storage.

To avoid condensation/corrosion problems, do not cover pump with plastic.
