INSTALLATION
1. This unit can be installed in sump pit with min-
imum 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.
Pump must be level (column
must be vertical) when oper-
ating. 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 careful-
ly to avoid stripping or crossing threads.
NOTICE: Do not use ordinary pipe joint com-
pound on plastic pipe or pump. Pipe joint com-
pound 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.
Risk of electric shock. Pump
is designed for 115V., 60 HZ
operation and requires an individual branch
circuit of 15 amperes capacity. It is supplied
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 sys-
tem.
6. Locate Float Rod Guide (Key No. 6) about 6"
(16cm) below motor. Clamp guide to column
with screw provided.
Risk of flooding. Be sure that
guide is securely clamped so
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 remain-
ing in pipe will drain to outfall by gravity.
Failure to do this can cause water trapped in
discharge to freeze which could result in dam-
age to pump.
12. Install an in-line check valve to prevent flow
backwards through pump after pump shuts off.
NOTICE: Simer check valves are equipped with
an air bleed hole to prevent airlocking the
pump. If using a check valve that is not a Simer
valve, 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.
The pump motor is equipped
with automatic resetting
thermal protector and may restart unexpected-
ly. Protector tripping is an indication of motor
overloading as a result of operating pump at
low heads (low discharge restriction), exces-
sively high or low voltage, inadequate wiring,
incorrect motor connections, or a defective
motor.
