STEP 4: Plumb vent. Plumb vent using 2" threaded pipe to fitting in basin cover.
Use pipe joint compound on threads and hand tighten only on plastic fittings.
The basin must be vented in accordance with state and local codes. The vent
is essential for proper switch operation and must not be omitted or restricted.
CAUTION: Do not use a mechanical vent with this product. A mechanical vent
will cause improper operation of the automatic switch.
STEP 5: Test unit. Connect power cord to electrical supply as stated under
“Electrical Connections.” Secure power cord to piping with ties or tape. Fill unit
with water through inlet. Pump should turn on with 7"–10" of water in tank, and
turn off when 2"–5" of water is left in tank.
MAINTENANCE
Maintenance operations consist of cleaning basin and limited pump mainte-
nance. WARNING: Before any maintenance is performed, shut off water inlet
and disconnect power cord from electrical supply outlet. Pump may become
hot in operation. Allow pump to cool before servicing.
BASIN: Sediment may build up in basin causing pump to operate improperly.
Remove (10) 1/4-20 screws from cover. Remove cord grommet and loosen cords
to allow slack and then remove cover.
Remove pump and clean basin using a mild detergent and water. Reassemble
in reverse order.
Torque screws 18-20 in.-lbs.
PUMP: Sediment or lint can clog pump and cause improper operation. If neces-
sary, remove pump from basin and remove the screws that hold the base plate
and screen to motor housing. Remove baseplate and screen and clean impeller
and volute passage. Do not use strong solvent on impeller. Clean using a mild
detergent and water and reinstall. See pump manual for other information. For
any other pump repair, return the pump to a Little Giant authorized service center.
