b. To minimize possible fatal electrical shock hazard, use extreme care
when changing fuses. Do not stand in water while changing fuses or
insert your finger into the fuse socket.
4. Do not operate the pump in a dry basin. This will cause the pump to become
extremely hot, causing burns if touched and/or damage to the pump.
5. Do not oil the motor. The pump housing is sealed. A high grade dielectric
oil devoid of water has been put into the motor housing at the factory. Use of
other oil could cause serious electric shock and/or permanent damage to the
pump.
6. This pump's motor housing is filled with a dielectric oil for motor heat transfer
and lifetime lubrication of the bearings. 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.
INSTALLATION
Install the pump in a suitable gas tight basin that is at least 18" in diameter and
30" deep. The pump features a 2" female NPT discharge. The ES60 has an
optional 3" female NPT discharge. The pump can be installed with ABS, PVC,
polyethylene, or galvanized steel pipe. Proper adapters are required to connect
plastic pipe to the pump.
Place pump on a hard level surface. Never place pump directly on clay, earth
or gravel surfaces.
Use a check valve in the discharge line to prevent back flow of liquid into the basin.
It should be a free-flow check valve that will easily pass solids.
CAUTION: For best performance when handling solids, install the check valve in a
horizontal position or at an angle of no more than 45°. Do not install check valve in a
vertical position as solids may settle in valve and prevent opening on start-up.
When a check valve is used, drill a relief hole (1/8" or 3/16" diameter) in the dis-
charge pipe. This hole should be located below the floor line between the pump
discharge and the check valve. Unless such a relief hole is provided, the pump
could air lock and will not pump water even though it will run.
Check local electrical and building codes before installation. The installation
must be in accordance with their regulations as well as the most recent National
Electrical Code (NEC).
To conform to the National Electrical Code all pumps must be wired with 14 AWG
or larger wire. For lengths to 250', 14 AWG wire is sufficient. For longer lengths,
consult a qualified electrician or the factory.
Connect or wire the pump to its own circuit with no other outlets or equipment
in the circuit line. Fuses and circuit breaker should be of ample capacity in the
electrical circuit (see table below).

OPERATION
TESTING PUMP OPERATION
1. This pump is equipped with an automatic switch. The pump must be plugged
into this switch for automatic operation.
2. When this pump is installed in a basin with a sealed cover, switch operation
cannot be observed. The sump cover usually has a spare hole that is plugged
with a rubber plug. Remove this plug to observe switch operation.
3. Plug the 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 operate through several on-off cycles.

If pump does not operate properly, consult the Troubleshooting table. If trouble
cannot be located with these steps shown, consult your pump dealer or take pump
to a Little Giant authorized service center.
WARNING: Before working on the pump or switch, unplug the pump power cord,
and remove the fuse or shut off the circuit breaker.
CLEANING IMPELLER AND VOLUTE
1. Remove 4 bolts that hold motor housing to volute.
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. CAUTION: 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.
