P11 ROUTINE MAINTENANCE
7. ROUTINE MAINTENANCE
The pump mechanical seal requires no lubrication and ser vice.
The only routine maintenance needed is the inspection and cleaning of
the pre-filter basket. Debris or trash collected in the basket will choke
off the water flow through the pump. Follow the instructions below in
order to clean the pre-filter basket:
1. Turn off the pump, close the gate valve in suction and discharge, and
release all pressure from the system before proceeding.
2. For SB pump series, turn the transparent Lid cover follow the arrow
on the Lid cover by lid ring opening key provided to release and lock .
3. Remove the pre-filter basket and cleaning. Make sure all the holes in
the basket are clear, flush the basket with water and replace it in the
trap with large opening at the pipe connection port (between rib
sprovided). If the basket is replaced back wards, the cover will not fit
on the trap body.
4. Clean and inspect the Lid's O-ring ring; reinstall on the Lid cover.
5. Clean the ring groove on the pre-filter body and replace the Lid. To
help keep the Lid from sticking, tighten it by hand only.
6. Put back the basket with opening face directly to the suction inlet as
the picture show above.
7. Fill up the filter body with water and Prime the pump.
8. WINTERIZING
If the air tempera ture drops below 0°C (35°F), the water in the system can freeze and cause damage. Freezing
damage is not warrantable.
To prevent freezing damage follow the procedures listed below:
1
.
Shut off electrical power for the pump at the house circuit breaker.
2
.
Drain the water out of the pump case by removing the two drain plugs from the case.
3
.
Store the plugs in the pump basket.
4
.
Cover the motor to protect it from severe rain, snow and ice.
5
.
If it is possible, store the pump in a dr y location during this time.
6
.
Do not wrap the motor in plastic. It will cause condensation and rust on the inside of the motor.
7
.
Where possible, have a qualified ser vice technician or electrician disconnect the electrical wiring at the switch
or junction box and store the pump indoors.
8
.
When the pump is reactivated, ensure all seals and O-rings are in operational condition. If they are not, re-
greasing or replacing may be necessar y.
