INSTALLATION

WARNING

building codes before installation. The installation must be in
accordance with their regulations as well as the most recent
National Electrical Code (NEC).
1. Pump must be installed in a suitable gas-tight basin that is at
least 18" in diameter and 24" deep, and vented in accordance
with local plumbing codes.
2. Clean any debris from sump pit and set pump in center of pit
(Figure 2). A solid bottom will prevent clogging of the pump
from sand and dirt.
3. The pump must be placed on a hard, level surface. Never place
the pump directly on clay, earth or gravel surfaces. These
surfaces contain small stones, gravel, sand etc. that may clog or
damage the pump and cause pump failure.
4. Do not attempt to restrict the intake side of these pumps.
Restricting the intake may cause damage to the seal and may
starve the pump. If you require reduced flow rates, place a valve
on the discharge side of the pump. Or, if flexible vinyl tubing is
used, a clamp can be used on the tubing to restrict the flow.
5. Connect discharge piping. 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/
effluent pump comes with 1-1/2" female pipe thread discharge.
a. Support pump and piping when assembling and when
installed. Failure to do so may cause piping to break, pump
to fail, motor bearing failures, etc.
b. 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.
Check local electrical and
6. A check valve must be used in the discharge line to prevent back
flow of liquid into the basin. The check valve should be a free
flow valve that will easily pass solids.
s
CAUTION
!
a.
check valve when handling solids, install 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.
b. 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.
7. Tape pump and switch cords to discharge line with electrician's
tape. This will protect the cord from damage.
8. Test operation of the sump system following the instructions
outlined in the "Sump System Operation Testing" section of this
manual. 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.
9. Place cover over sump. This cover will help prevent debris from
entering the pit and will guard against accidental injury.
