Installation / Operation
Installation Instructions. See Figure 1.
1. Dig the hole for the basin and the sub-base. The hole
must be deep enough so the top of the basin is flush
with the finished floor. Refer to Figure 1, Page 4.
NOTICE: The sub-base should include 4" of sand or
gravel. The maximum diameter of crushed rock should
be 1/2". The recommended maximum diameter of pea
gravel is 3/4".
2. Level the sub-base out until it is smooth. Sharp rock
can damage the basin.
3. Reach into the inlet hole to retrieve the hardware kit.
Locate the cord grommet in the hardware kit.
4. Reach into the inlet hole again to pull the power cord
up through the cord grommet hole in the cover. Press
the cord into the cord grommet and install the
grommet in the cover.
5. Locate the inlet hub in the hardware kit, and snap it
into the inlet hole.
6. Install the basin on top of the sub-base.
7. Insert a 4" inlet pipe through the inlet hub. Insert it 2"
into the basin. Dish soap can be used to lubricate the
inlet hub. If necessary, file the sharp edges of the pipe
to prevent damage to the hub.
NOTICE: The inlet pipe should pitch down to the basin
inlet at 1/4" per foot. This will cause the water to run
into the basin.
8. Backfill around the basin with crushed rock, with a
maximum diameter of 1/2", or use pea gravel.
9. Install a 1-1/2" discharge pipe into the 1-1/2" FNPT
discharge flange.
10. Install a 2" vent pipe into the 2" FNPT threaded vent
flange. The vent pipe must go through the roof of the
building or it can be connected to an existing vent
pipe. The sump basin must be vented.
NOTICE: Proper ventilation is needed to prevent
negative basin pressure and to provide the necessary
air within the basin. Do not use a 1-way vent of any
kind.
11. Install the 1-1/2" check valve (supplied) in the
discharge pipe. See Figure 1. Make certain the flow
indicating arrow points away from the pump. This
check valve will keep the water from running back into
the basin when the pump is not running.
NOTICE: To prevent clogging the pump, clear basin
of any debris if you remove the cover during or after
installation. Unplug the pump first.
12. Plug the pump into a properly grounded outlet.
13. Check the operation by filling the basin with water
and observing pump operation through one complete
cycle. Make sure that no parts of the assembly interfere
with the float.
Failure to make this operational check may
lead to improper operation, premature failure, and
flooding.
OPERATION
NOTICE: The shaft seal depends on water for lubrication
and cooling. Do not operate the pump unless it is
submerged in water as the seal may be damaged if allowed
to run dry. Allowing the pump to run dry will void the
warranty.
An automatic overload protector in the motor will
protect the motor from burning out due to overheating/
overloading. When the motor cools down, the overload
protector will automatically reset and start the motor.
If the overload trips frequently, check for the cause. It
could be a stuck impeller, wrong/low voltage, or an
electrical failure in the motor. If an electrical failure in
the motor is suspected, have it serviced by a competent
repairman.
Purchase inlet, vent and
discharge pipes locally.
Plug the Pump
into a Properly
Grounded Outlet.
