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.
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.
ELECTRICAL CONNECTIONS
WARNING:
Always disconnect the electrical power before touching the pump or discharge when water is present in the
area of the pump. Failure to do so can result in hazardous electrical shock.
1.
Your sump pump is supplied with a stripped wire cord end. The end of the power cord is to be wired in an electrical
enclosure. Be sure that electrical connection cannot be reached by rising water. Under no circumstances should the
outlet box be located where it may become flooded or submerged by water. The power cord is color coded as
follows, green (or green/yellow) - ground, black (or brown) - line, and white (or blue) - neutral.
2.
A separate branch circuit is recommended. Do not use extension cords.
3.
Automatic power cord contains a breather tube. Be sure power cord is not pinched so that breather tube is
obstructed. Non-restrictive air flow in breather tube is required for proper operation.
4. Test the pump after all electrical connections have been made. Run water into area where pump is to be placed.
Do not attempt to run the pump without water; this could result in permanent damage to the pump. Fill the area to a
normal “on” level and allow the pump to remove water to a normal “off” level.
INSTALLATION
Little Giant automatic sump pumps have a high volume pumping capacity with a pressure activated switch. The switch
engages in 7” - 10” water.
1.
Clean any debris from sump pit and set pump in center of pit (Figure 1). 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 11⁄2” female pipe thread discharge, and 11⁄4” 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 cord to discharge line with electrician’s tape. This will protect the cord from damage and will prevent the
pump’s being pulled from the sump by its power cord.
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 (Figure 1).
7.
Place cover over sump. This cover will prevent solid debris from filling the pit, prevent odors, and guard against
accidental injury.
