MANUAL PUMP
World's Largest Manufacturer of Centrifugal Pumps
Little Giant pumps are carefully packaged, inspected and tested to insure
safe operation and delivery. When you receive your pump, examine it
carefully to determine that there are no broken or damaged parts that may
have occurred during shipment. If damage has occurred, make notation
and notify the firm you purchased the pump from. They will assist you in
replacement or repair, if required.
electrical connections
(See Fig. 1)
The motor section of your pump is permanently lubricated and sealed
- do not attempt to open this section. Special equipment and knowledge
is required for proper servicing of this part of your pump and may only be
accomplished by an Authorized Service Center or the factory. Your warranty
will be void if the motor section is opened by unauthorized persons.
Your sump pump is supplied with a 3 prong electrical plug. The third
prong is to ground the pump to prevent possible electric shock hazard.
Do not remove the third prong from the plug. A separate branch electrical
circuit is recommended. Do not use an extension cord.
Safety guidelines
1. CAUTION: To reduce the risk of electrical shock, pull plug before
servicing this pump.
2. Read all instructions and safety guidelines thoroughly. Failure to
follow the guidelines and the instructions could result in serious injury
and/or property damage.
3. Check local electrical and building codes before installation. The
installation must be in accordance with their regulations.
4. During normal operation the sump pump is immersed in water. Also,
during rain storms, water may be present in the surrounding area
of the pump. Caution must be used to prevent bodily injury when
working near the pump:
a. The plug must be removed from the receptacle prior to touching,
servicing or repairing the pump.
b. To minimize possible fatal electrical shock hazard, extreme care
should be used when changing fuses. Do not stand in water while
changing fuses or insert your finger into fuse socket.
5. Do not run the pump in a dry sump. If the pump is run in a dry sump,
the surface temperature of the pump will rise to a high level. This high
level could cause skin burns if the pump is touched and will cause
serious damage to your pump.
6. 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.
7. This pump’s motor housing is filled with a dielectric lubricant at the
factory for optimum motor heat transfer and lifetime lubrication of the
bearings. Use of any other lubricant could cause damage and void the
warranty. This lubricant is non-toxic; however, if it escapes the motor
housing, it should be removed from the surface quickly by placing
newspapers or other absorbent material on the water surface to soak
it up, so aquatic life is undisturbed.
FIG. 1
INSTALLATION (See Fig. 2)
1. Clean any debris from sump pit and set pump in center of pit. A solid
bottom will prevent clogging of the pump from sand and dirt.
2. Connect discharge piping and run it to the nearest sewer or surface
outlet. Use pipe joint compound at all connections. Sump pumps can
be piped to discharge into the house drainage system, to a dry well,
splash block or to a storm drain, depending on local plumbing codes.
The discharge pipe should be as short as possible and contain as few
elbows as possible. The discharge pipe should be the same diameter
as the discharge size to reduce pipe friction losses. Smaller pipe will
restrict capacity and reduce pump performance. The sump pump
comes with 1" female pipe thread discharge, and a 1" FNPT reducing
bushing.
3. Always install a union in the discharge line, just above the sump pit,
to allow for easy removal of the pump for cleaning or repair.
4. In situations where the piping is long, the vertical discharge is above
7 or 8 feet, or a small pit has been provided, use of a check valve
is recommended to prevent backflow of water into the sump. When
a check valve is used, drill a relief hole (1/8" or 3/16" diameter) in
the discharge 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.
5. Tape power cords to discharge line with electrician’s tape. This will
protect the cords from damage and will prevent the pump being
pulled from the sump by its power cord.
8. In any installation 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.
6. TEST THE PUMP AFTER ALL CONNECTIONS HAVE BEEN MADE.
Run water into sump. Do not attempt to operate the pump without
water; this will damage the seals and bearings and could result in
permanent damage to the pump. Fill sump to normal “on” level and
allow pump to remove water to the normal “off” level (see fig. 2).
warning
7. Place cover over sump. This cover will prevent solid debris from filling
the pit, prevent odors, and guard against accidental injury.
Risk of electric shock - This pump is supplied with a grounding conductor
and grounding-type attachment plug. To reduce the risk of electric shock,
be certain that it is connected only to a properly grounded, groundingtype receptacle. As a safety measure, each electrical outlet should be
checked with an Underwriters Laboratory Listed circuit analyzer. This will
indicate if the power, neutral and ground wires are properly connected. If
they are not, call a qualified licensed electrician.
REMOTE FLOAT SWITCH
LEVEL CONTROL
The RFS series pumps are equipped with a remote float switch level
control. This level control is sealed in a polypropylene float cylinder.
For automatic operation, the pump must be plugged or wired into a
remote float switch. Pump will run continuously if plugged directly into an
electrical outlet.
When the level rises in the basin, the cylinder floats up with the level.
When the cylinder position is at an angle of about 45 degrees, the switch
activates and starts the pump motor.
As the level draws down, the cylinder floats down and when it is again
at an angle of about 45 degrees, the switch deactivates, and the pump
motor stops.
NOTE: BE CERTAIN PUMP IS SECURE IN BASIN AND CYLINDER
FLOATS UNOBSTRUCTED WITHOUT TOUCHING THE BASIN WALLS
OR PLUMBING.
REMOTE FLOAT SWITCH
INSTALLATION
TYPICAL INSTALLATION
1. The float switch consists of three parts:
a) switch
b) cord clamp
c) clamp screw
NOTE: If screw is lost, use a #10-16 X 1/2" long tapping screw. Longer
screws can crack the cover.
2. Attach cord clamp to pump cover as shown in the switch instruction
manual packaged with the switch. The clamp and pump handle must
be positioned as shown to allow free operation of float. Be sure to
locate pump and switch power cords away from switch float.
3. Tether length to be 3½" when attached to pump. When a tether length
of 3" is used, a minimum basin diameter of 18" is recommended.
4. After desired tether length is established hand tighten clamp screw.
5. TESTING: Without water in basin, plug pump power cord into switch
in-line-plug. Plug switch into outlet. Lift float and watch for pump to
operate. Do not run pump for more than 5 seconds.
WARNING: Always disconnect the electrical power before
touching the pump or discharge when water is present in the
sump. Failure to do so can result in hazardous electrical shock.
TROUBLE SHOOTING INFORMATION
