General Safety Information
(Continued)
The pump motor
is equipped with
automatic resetting thermal protector
and may restart unexpectedly. Protector
tripping is an indication of motor
overloading as a result of operating
the pump at low heads (low discharge
restriction), excessively high or low
voltage, inadequate wiring, incorrect
motor conditions, or a defective motor
or pump.
14. IThis pump is designed to transfer
water in cycles. Using this pump in
a continuous duty application by
ma nip u lat ing the switch to stay on,
will affect the per for mance and the
life of the product.

15. Protect electrical cord from sharp
objects, hot sur fac es, oil, and
chemicals. Avoid kinking the cord.

carry handle. Sewage pumps
should be set firmly on their legs
and supported by rigid piping. This
eliminates twisting and damage
during pump operation.

Installation
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, use a
backup system(s).

1. Thread the discharge pipe or pipe
nipple into the dis charge connection.
2. If a check valve is used in a solids
handling system mount the check
valve in a horizontal position or at
valve in a horizontal position or at
a 45º angle with the valve pivot on
top. In a vertical position, solids will
tend to lodge on the valve flapper
and can prevent it from opening.

3. Drill a 1/8 inch hole in the discharge
pipe ap prox i mate ly 1 inch to 2 inch
above the pump discharge when
a check valve is used. The hole
prevents air locking of the pump at
the initial start-up and if it should
lose prime.

4. A gate valve should be installed in
the system after the check valve. This
gate valve should be a full port valve
which will pass 3/4 inch solids or as
required by state and local codes.
This gate valve permits removal of
the pump and/or check valve for
servicing.

5. A union should be installed between
the check valve and the pump so the
pump can be removed with least
disturbance of the piping.

6. The pump has a detachable tether
switch with a piggyback plug (see
Figure 3). The length of the tether
(distance of cord from float to
clamp) should not be set shorter
than 3-1/4 inches and should not
be used in a basin smaller than
14 inches in diameter. If using a
differential other than the factory
setting, be sure when the pump
shuts off at least 4 inch of fluid is left
in the basin so the impeller remains
submerged.

7. When a tether switch is used, rigid
dis charge pipe is required. If the
pump is allowed to move, the
tether switch could be re strict ed
by the basin wall, pre vent ing the
pump from operating.

Before removing
pump from basin
for service, always disconnect electrical
power to pump and control switch. For
any work on pump or switch, ALWAYS
unplug the power cord. Do not just turn
off circuit break er or unscrew fuse.

1. Disassembly of the motor prior to
expiration of war ran ty will void
the warranty. It might also cause
internal leakage and damage to the
unit. If repairs are required, return
the pump to the dealer from whom
it was pur chased or call 1-800-237-

the o-rings must be replaced. Care
must be taken to ensure that all
seals do not leak.
