ings. This oil is non-toxic to aquatic life.
However, suffocation can occur if oil is
left on the water surface. If oil escapes the
motor housing it can be removed from the
surface quickly by placing newspapers
on the water surface to soak up the oil.
7. In any installations where property damage
and/or personal injury might result from an
inoperative or leaking pump due to power
outages, discharge line blockage, or any
other reason, a backup system(s) and/or
alarm should be used.
OPERATION
TESTING PUMP OPERATION
ES33 SERIES SUMP PUMPS:
1. All pumps except ES33M are equipped
with an automatic switch. Pump must be
plugged into switch for automatic opera-
tion.
2. When these pumps are installed in a basin
with a sealed cover, switch operation cannot
be observed. The sump cover usually will
have a spare hole that is plugged with a
rubber plug. This plug can be removed and
switch operation can be observed.
3. Plug power cord into a grounded receptacle
with voltage consistent with pump voltage
as indicated on pump nameplate.
4. Run water into basin until pump starts.
5. Be sure gate valve in discharge line is
open.
6. Allow
pump
to
on-off cycles.
MAINTENANCE
If pump does not operate properly, consult the troubleshooting
chart. If trouble cannot be located with these steps shown, consult
your pump dealer or take pump to a Little Giant authorized service
center.
CAUTION: When working on pump or switch, always unplug
pump power cord in addition to removing fuse or shutting off cir-
cuit breaker before working on pump.
CLEANING IMPELLER AND VOLUTE
1. Remove (8) screws that hold screen to volute, and volute to
motor housing.
2. Remove volute and clean impeller and volute passage. Do not
use strong solvents on impeller.
3. Be sure impeller turns freely after cleaning.
4. WARNING: DO NOT REMOVE IMPELLER. REMOVAL OF
IMPELLER REQUIRES SPECIAL TOOLS AND IS TO BE DONE
ONLY BY AN AUTHORIZED SERVICE CENTER.
DO NOT REMOVE MOTOR HOUSING COVER. WARRANTY
IS VOID IF MOTOR HOUSING COVER, IMPELLER OR SEALS
HAVE BEEN REMOVED.
ANY REPAIR ON MOTOR MUST BE DONE BY AN AUTHORIZED
LITTLE GIANT SERVICE CENTER.

The motor housing contains a cooling oil to
provide cooling for the motor and to lubricate
bearings and seals. These pumps are capable of
operating with the motor housing partially exposed
for extended periods of time, providing sufficient
motor cooling and bearing lubrication. However,
for the best cooling and longest motor life, the
liquid level being pumped should normally be
above the top of the cast iron motor housing.
