Maintenance - Little Giant FR Series Installation And Operation Manual

Out-of-Water (Non-Submersible) Installation
Refer to Figure 3, Figure 4, and the following steps to configure the
pump for out-of-water (non-submersible) use:
1. Locate the connection box in a dry area at least 6-1/2 feet (2
meters) from the edge of the water.
2. Place the pump out of the water and below water level,
ensuring that water can flow into the pump. (The pump is not
self-priming.)
3. FP1, FP2, and FP3 ONLY: The discharge can be configured
to point up or to the side, depending on the application. To
redirect the discharge, loosen the four clip screws (1), turn the
motor housing (9) until the discharge is in the desired position,
and tighten the screws.
4. Connect an intake hose (S) and discharge hose (D) to the
pump, ensuring that the connections are watertight. NOTE: To
help prevent clogging, use a pre-filter on the intake hose. For
easier installation, use Little Giant installation kit 566259 and
leaf basket 566106 (optional).
5. Fill the intake hose and the volute with water.
6. Connect the pump to power.
7. Observe that the pump operates properly. Ensure that the
pump will not run dry; without a continuous supply of water
damage will result and void the warranty.
8. If reduced flow is required, restrict the discharge. Never restrict
the intake.

MAINTENANCE

DISCONNECT THE PUMP
ATTEMPTING TO SERVICE OR REMOVE ANY COMPONENT!
CAUTION: Do not let the pump freeze. This can cause cracking or
distortion that will damage the pump.
NOTE: This pump has no user-serviceable parts. The motor
housing is sealed and does not require service. Disassembly of
the motor housing will void the warranty.
NOTE: The power cord is not replaceable. If it becomes damaged,
the entire pump must be replaced. Alteration of the power cord will
void the warranty.
NOTE: How often the pump requires cleaning depends upon the
cleanliness of the water it pumps. When using the pump in hard
water, clean the rotor assembly and the motor housing more often.
