Maintenance
TO PREVENT SERIOUS INJURY FROM
ACCIDENTAL OPERATION:
Unplug the Pump from its electrical outlet and
ALLOW TO COOL FOR AT LEAST 2 HOURS
before performing any inspection,
maintenance, or cleaning procedures.
1. Before each use, inspect the general condition of the
Pump. Check for cracked or broken parts, damaged
electrical wiring, clogged Impeller Cover, Impeller,
Discharge Pipes, leaks and loose connections, and
any other condition that may affect safe operation. If
abnormal noise or vibration occurs, have the problem
corrected before further use.
Do not use damaged equipment.
2. Keep the Sump Basin clean. Clean out the
sump basin regularly and keep the cover in
place to keep it clean. Sand and other debris
can interfere with pump operation, can block the
air bleed hole, or can cause premature wear.
3. Clean out the air bleed hole periodically.
Quarterly Maintenance
The below maintenance must be performed at least
once every 3 months under optimal conditions.
For frequent use, or dirty areas,
more frequent maintenance is required.
1. Remove the Sump Basin Cover.
2. Clean sludge and debris from the bottom of the shaft.
3. Rinse the housing off with clean water.
4. Clean fibers from inside the pump housing
with a pressure washer (not included).
5. If the pump housing cannot be cleaned from
the outside, it must be thoroughly cleaned.
Unplug the power cords before maintenance.
Dismantle the bottom part of the pump as follows:
a. Remove the Screws at the bottom of the Base.
b. Remove the Base to expose the
Impeller Cover and Impeller.
c. Clean the impeller with clean water.
d. To prevent damage, do not rest the pump on
the impeller or pry against the impeller.
e. Reassemble in reverse order.
6. Make sure the float switch can operate
freely, without obstructions.
7. Replace the Sump Basin Cover.
Cold Weather Storage
In cold weather, when the Pump is not in use,
protect the interior of the Pump from freezing by
draining the water and pumping a permanent type
automobile anti-freeze containing a rust inhibitor
through the system. A 50% mixture with water is
recommended. Be sure to flush the system with a
neutralizing liquid prior to re-use of the Pump.
