OPERA TION
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.
Hazardous suction.
Can trap hair or
body parts, causing
severe injury
or death.
Do not block
suction.
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.
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-
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.
