OPERATION
NEVER run pump dry. If the pump is run dry, the
mechanical seal will be
damaged and the pump will
start leaking. If this occurs,
the damaged seal must be
replaced. ALWAYS maintain
proper water level. If the water
level falls below the suction
port, the pump will draw air
through the suction port,
losing the prime and causing
the pump to run dry, resulting
in a damaged seal. Continued
operation in this manner could
cause a loss of pressure,
resulting in damage to the
pump case, impeller and seal
and may cause property
damage and personal injury.
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.
4.
To reduce risk of injury” before NEVER
tighten or loosen clamp while pump is operating!
If pump is being pressure tested, be sure pressure
has been released before removing trap cover.
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.
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.
NOTICE: Maximum ambient temperature for motor
operation must not exceed maximum ambient
temperature rating on motor model plate.
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, remove trap
cover handle ring and trap cover; fill trap and pump with
water.
Do not lubricate the trap cover O-Ring. The original
equipment O-Ring contains a permanent internal
lubricant.
NOTICE: If you replace the O-Ring with a non-internally
lubricated O-Ring, you may need to apply a silicone
based lubricant.
Clean and inspect O-Ring; reinstall on trap.
Replace trap cover and handle ring on trap; turn handle
ring clockwise to tighten cover.
Do not use a wrench, this may damage the
trap cover handle ring which can cause property
damage or personal injury.
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.

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
counterclockwise). 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 (between
ribs provided). If basket is
replaced backwards cover
will not fit on trap body.
4.
Clean and inspect lid
O-Ring; reinstall on trap.
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).
Hazardous voltage.
Can shock, burn,
or cause death.
Disconnect power
before working
on pump or motor.
