CHECK
Inspect trap basket, and empty
of any leaves and other debris.
Leaves and other debris that
collects in basket will choke
off water ow through the
pump and reduce eciency
and performance. See below
instructions on cleaning the trap.
Check the pump to ensure no
water is leaking from inlet and
outlet joints, whilst pump is
operating. If leaks are noticed,
clean and grease the o-rings or
replace if necessary.
Clean area around pump and
ensure there are no leaves or
debris which could become a re
hazard or choke the motor fan.
Check that there are no leaks
from under the pump. If there are,
this could be a sign of a leaking
mechanical seal. Call a Pentair
Service Agent immediately, to
prevent damage to the motor.
Check pump and motor for
insects and pest infestations
and ensure that motor ns are
clean of dust and dirt. Clean if
necessary.
To avoid dangerous or fatal
electrical shock hazard, turn OFF
power to pump and remove plug
from power outlet before working on
pump.
Do not operate pump with trap
basket missing or damaged.
Follow instructions below to clean trap:
1. Switch off power to pump, close valves in suction and discharge, and release all pressure from
system before proceeding.
2. Remove trap cover (turn counter clockwise). If necessary, tap handles gently with a rubber
mallet.
3. Remove strainer basket and clean. Ensure 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, the cover will not fit on trap body. To clean transparent cover, use water
and neutral soap only. Do not use solvents.
