1. This unit can be installed in sump pit with
minimum diameter of 12" (30cm) and depth
of 12" (30cm). Sump pit may be constructed
of tile, concrete, steel or plastic. Check local
codes for approved materials.
2. Install pump on solid, level foundation, as near
as possible to center of sump pit. Do not hang
pump from discharge pipe or power cord.
operating. If motor is tilted, internal start/run
switch may overheat and damage motor.
3. Pump should not be installed on clay, earth or
sand surfaces. Clean sump pit of small stones
and gravel which could clog the pump. Keep
pump inlet screen clear.
4. Thread discharge pipe into pump body
carefully to avoid stripping or crossing threads.
notice: Do not use ordinary pipe joint
compound on plastic pipe or pump. Pipe joint
compound can attack plastics and damage
pump.
5. To reduce motor noise and vibrations, a short
length of rubber hose (1-5/8" (41mm) I.D., e.g.
radiator hose) can be connected into discharge
line near pump using suitable clamps.

is designed for 115V., 60 HZ
with a 3-wire cord set with grounding-type plug
for use in a 3-wire, grounded outlet. Do not cut
off the round grounding prong. for safety,
outlet must always be electrically grounded to a
suitable electrical ground such as a grounded
water pipe or a properly grounded metallic
raceway or ground wire system.
6. Locate Float Rod Guide (Key No. 6) about 6"
(16cm) below motor. Clamp guide to column
with screw provided.
that float rod is vertical and can move up and
down freely. If float is angled or binds, pump
may not start, allowing flooding to occur.
7. Screw float onto threaded end of rod. Threads
on rod will cut threads into corrosion resistant
float.
8. Insert plain end of float rod up through eye of
rod guide.
9. Slide one rod stop on float rod before passing
rod through eye of pump switch. Slide 2nd rod
stop on rod after passing through eye of switch.
Position 2nd rod stop flush with top of rod.
10. Position lower rod stop to within 8"(20cm) of
switch lever arm. With lower rod stop in this
position, pump will automatically cycle at
approximately 2-1/2" (6cm) off and 10-12"
(25-30cm) on. For faster cycling, move lower
rod stop closer to switch lever arm.
11. If pump discharge line is exposed to outside
subfreezing atmosphere, then portion of
line exposed must be installed so any water
remaining in pipe will drain to outfall by
gravity. Failure to do this can cause water
trapped in discharge to freeze which could
result in damage to pump.
12. Install an in-line check valve (Myers model
24377A000) to prevent flow backwards
through pump after pump shuts off.
notice: The check valve should be equipped
with an air bleed hole to prevent airlocking
the pump. If using a check valve without an
air bleed hole, drill a 1/8" (3.2mm) hole in
discharge pipe just above pump body but
below the check valve to prevent air locks.
13. After all piping and controls have been
installed, unit is ready for operation.
14. Run pump through one cycle to check float
switch operation.

unexpectedly. protector tripping is an
indication of motor overloading as a result of
operating pump at low heads (low discharge
restriction), excessively high or low voltage,
inadequate wiring, incorrect motor
connections, or a defective motor.
