OPERATION

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.

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

Do not block pump suction! To do so with body may
cause severe or fatal injury. Small children using pool

must ALWAYS have close adult  supervision.

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 discharge
valves are opened.
If pump is not in a flooded suction system, unscrew T-bolt
trap handles and remove trap cover; fill trap and pump with
water.
Clean and lubricate trap cover O-Ring with petroleum jelly
each time it is removed.

Replace trap cover on trap; tighten T-bolt trap handles. 
Pump should prime now. Priming time will depend on 
vertical length of suction lift and horizontal length of 
suction piping.
If pump does not prime, make sure that all valves are open,
suction pipe end is under water and that there are no leaks
in suction pipe.   See Troubleshooting Guide, Page 9.

STORAGE/WINTERIZING

Allowing pump to freeze will damage pump and
void warranty!

Do not use anti-freeze solutions (except propylene
glycol) in your pool/spa system. Propylene glycol is

non-toxic and will not damage plastic system 
components; other antifreezes 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 film or bags.
For outdoor/unprotected installations:
1. Enclose entire system in a weatherproof enclosure.
2. To avoid condensation/corrosion damage, allow 

ventilation; do not  wrap system in plastic film.

3. Use a 40% propylene glycol/60% water solution to 

protect pump to -50 degrees F.

Draining Pump

1. Pump down water level below all inlets to the pool.

Hazardous voltage. To avoid dangerous

or fatal electrical shock hazard, turn OFF power to
motor before draining pump or working on pump or
motor.

2. Remove trap cover and use low pressure air to blow 

accumulated water from the piping system.

3. Cap inlet piping after draining to keep water out of the

pipes.

4. To prevent pump from freezing, remove trap cover and

drain the tank body through the drain plug (Key 10, 
Page 10). Clean pump thoroughly; replace trap cover.

6. Be sure motor is kept dry and covered.

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

Do not block
suction.
