pipe joint compound and hand tighten only on plastic fittings. Do not reduce
below 1-1/2” piping.
3. Plumb discharge to basin cover fitting using 1-1/2“ threaded pipe. Use a
swing check valve no more than 3” from top of basin cover and a union.
Be sure check valve is installed in proper flow direction. If check valve
is installed backwards, no water will flow out of unit. Be sure discharge
piping is sealed with pipe joint compound and that lift height of pump is not
exceeded. Hand tighten only on plastic fittings.
4. Plumb vent to fitting in basin cover using 2” threaded pipe. Use pipe joint
compound on threads and hand tighten only on plastic fittings. Vent basin
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.
5. Connect power cord to electrical supply according to ELECTRICAL
CONNECTIONS section. Secure power cord to piping with ties or tape. Fill
unit with water through inlet. Pump should turn on with 6” to 7-3/4“ of water
in tank, and turn off when 3/4” to 1-1/2” of water is left in tank.
ELECTRICAL CONNECTIONS
All wiring must meet local codes, and a licensed electrical contractor is
recommended. The pump is supplied with a 3-prong vented plug. Plugs must
be plugged into a grounded receptacle and vent tube must remain unobstructed
for proper pump operation. Pump should be on a separate circuit with fuse or
circuit breaker and ground fault circuit interrupter (GFCI). Be sure electrical
supply matches pump nameplate data. Do not use extension cord. If installed in
basement, plug connection should be 4 feet or more above floor, especially if
basement floods. Be sure electrical connections cannot be reached by rising
water. Under no circumstances should outlet box or receptacle be located
where it may become flooded or submerged by water.
MAINTENANCE
WARNING: Before performing any maintenance, shut off water inlet and
disconnect power cord from supply outlet. Pump may become hot during
operation. Allow pump to cool before servicing.
Basin Screen
Remove four 1/4-20 screen cover plate screws, plastic cover plate, o-ring, and
screen. Clean inlet screen using a mild detergent and water. Examine o-ring and
if deformed, replace with new o-ring. See replacement parts list.
Basin
Sediment may build up in basin causing pump to operate improperly. Remove
ten 1/4-20 screws from cover. Remove cord grommet, loosen cords to allow
slack, and remove cover.
Remove pump and clean basin using a mild detergent and water. Reassemble
in reverse order.
Torque screws to 18-20 in.-lbs.
If pump alignment plate is removed, reinstall it according to pump alignment
diagram.
Pump
Sediment or lint can clog pump and cause improper operation. If necessary,
remove pump and pull off the pressed-in screen, clean using a mild detergent
and water, and reinstall. Plastic pump base may also be removed to clean
around impeller and inside base. Remove the 6 base screws and clean base
using a mild detergent and water. Do not remove impeller. When reinstalling
base, be sure seal ring is seated properly in groove and torque screws to 10-
15 in.-lbs. See pump manual for other information. For any other pump repair,
return the pump to a Little Giant authorized service center.
INTRODUCTION
EN
This instruction sheet provides you with the information required to safely own and
operate your Little Giant pump. Retain these instructions for future reference.
The Little Giant pump you have purchased is of the highest quality workmanship
and material, and has been engineered to give you long and reliable service.
Little Giant pumps are carefully tested, inspected, and packaged to ensure safe
delivery and operation. Please examine your pump carefully to ensure that no
damage occurred during shipment. If damage has occurred, please contact the
place of purchase. They will assist you in replacement or repair, if required.
READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO
INSTALL, OPERATE, OR SERVICE YOUR LITTLE GIANT PUMP. KNOW
THE PUMP’S APPLICATION, LIMITATIONS, AND POTENTIAL HAZARDS.
PROTECT YOURSELF AND OTHERS BY OBSERVING ALL SAFETY
INFORMATION. FAILURE TO COMPLY WITH THESE INSTRUCTIONS
COULD RESULT IN PERSONAL INJURY AND/OR PROPERTY DAMAGE!
DESCRIPTION
READ BEFORE INSTALLATION! This unit is designed to pump wastewater from
laundry trays, washing machines, sinks, or dehumidifiers. It is not designed to
pump raw sewage, fluids other than water, or fluids with solids. The inlet screen
will remove many solids over 1/8” in diameter, but large amounts of solids can
clog screen and result in pump failure. Maximum fluid temperature is 125° F.
Unit is designed to fit under most sinks, so in many cases it is not necessary to
recess the unit into the floor.
ITEMS TO PURCHASE
NOTE: Some state or local codes require all electrical and/or plumbing
connections to be made by a licensed contractor. It is the customer’s
responsibility to determine codes involved and to comply with these codes. If
user can install unit, items to purchase are:
1. Inlet piping with trap and union. (Basin cover has 1-1/2” FNPT fitting.)
2. Discharge piping with swing check valve and union. (Basin cover has 1-1/2”
FNPT fitting.)
3. Vent piping. (Basin cover has 2” FNPT fitting.)
SAFETY GUIDELINES
CAUTION: During normal operation the pump is immersed in water. Use caution
to prevent bodily injury when working near the pump. Remove the power plug
from the power source prior to touching, servicing, or repairing the pump.
Read all instructions and safety guidelines thoroughly. Failure to follow the
guidelines and the instructions could result in serious bodily injury and/or
property damage.
Check local electrical and building codes before installation. The installation
must be in accordance with these regulations.
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 fuse socket.
INSTALLATION
All plumbing must meet local codes. A licensed plumbing contractor is
recommended. All fixtures connected to the WRS-5 must be vented according
to state and local codes.
1. Determine the proper location for the unit. Locate it so that the inlet
is gravity-fed. Unit will not
draw water up from a lower
level. Position and level
basin. Keep basin away
from any item that could
puncture basin. Position se-
lected should be convenient
to inlet, discharge and vent
piping and electrical supply.
2. Plumb inlet to basin cover
fitting using 1-1/2“ threaded
pipe. Use a P-trap and a
union next to the basin. Use
