Float Switch Installation - Simer 2956 Series Owner's Manual

Installation
12. This equipment is only for use on 115 volt
(single phase) and is equipped with an
approved 3-conductor cord and 3-prong,
grounding-type plug.
Risk of electric shock. Pull plug
before servicing. This pump has not been
investigated for use in swimming pool areas.
Pump is supplied with a grounding conductor
and grounding-type attachment plug. Be sure
it is connected only to a properly grounded
grounding-type receptacle.
Where a 2-prong wall receptacle is
encountered, it must be replaced with properly
grounded 3-prong receptacle installed in
accordance with codes and ordinances
that apply.
13. All wiring should be performed by a
qualified electrician.
14. Make certain power source conforms to
requirements of your equipment.
15. Protect electrical cord from sharp objects, hot
surfaces, oil, and chemicals. Avoid kinking
cord. Replace or repair damaged or worn
cords immediately.
16. Do not touch an operating motor. Motors can
operate at high temperatures.
17. Do not handle pump or pump motor with
wet hands or when standing on wet or damp
surface, or in water.
Risk of electric shock. If your
basement has water or moisture on floor, do
not walk on wet area until all power has been
turned off. If shut-off box is in basement, call
electric company or hydro authority to shut-
off service to house, or call your local fire
department for instructions. Remove pump and
repair or re place. Failure to follow this warning
can result in fatal electrical shock.
Do not lift pump by power cord.

Float Switch Installation

Models equipped with vertical switches require
some assembly. See the Vertical Switch Assembly
instructions on page 4.
Installation
1. Install pump in sump pit with minimum
diameter of 10" (254mm). Sump depth should
be 10" (254mm). Construct sump pit of tile,
concrete, steel or plastic. Check local codes for
approved materials and for proper installation.
2. Install pump in pit so that switch operating
mechanism has maximum possible clearance.
3. Pump should not be installed on clay, earth or
sand surfaces. Clean sump pit of small stones
and gravel which could clog pump. Keep
pump inlet screen clear.
For parts or assistance, call Simer Customer Service at 1-800-468-7867
NOTICE: Do not use ordinary pipe joint
compound on plastic pipe. Pipe joint
compound can attack plastics.
4. Install discharge plumbing. Use rigid plastic
pipe and wrap threads with PTFE pipe thread
sealant tape. Screw pipe into pump hand tight
plus 1-1/2 turns.
Risk of flooding. If a flexible
discharge hose is used, make sure pump is
secured in sump to prevent movement. Failure
to secure pump may allow pump movement,
switch interference and prevent pump from
starting or stopping.
5. To reduce motor noise and vibrations, a
short length of rubber hose (1-7/8" (47.6mm)
I.D., e.g. radiator hose) can be connected
into discharge line near pump using
suitable clamps.
6. Install an in-line check valve or an in-pump
check valve to prevent flow backwards through
pump when pump shuts off.
NOTICE: Check valves should be equipped
with an air bleed hole to prevent airlocking
pump. If not, drill a 1/8" (3.2 mm) hole in
discharge pipe just above where the discharge
pipe screws into the pump discharge. Be sure
the hole is below the waterline and the check
valve to prevent air locks.
7. Power Supply: Pump is designed for 115 V.,
60 Hz., operation and requires a minimum
15 amp individual branch circuit. Both pump
and switch are supplied with 3-wire cord sets
with grounding-type plugs. Switch plug is
inserted directly into outlet and pump plug
inserts into opposite end of switch plug.
Risk of electric shock. Pump
should 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. Do not cut off
round ground pin.
8. If pump discharge line is exposed to outside
sub-freezing atmosphere, portion of line
exposed must be installed so any water
remaining in pipe will drain to the outfall
by gravity. Failure to do this can cause water
trapped in discharge to freeze which could
result in damage to pump.
9. After piping, check valve and float switch have
been installed, the unit is ready for operation.
10. Check the pump operation by filling sump with
water and observing pump operation through one
complete cycle. For switch settings see Electrical
& Switch Specifications.
Risk of flooding.Failure to make
this operational check may lead to improper
operation, premature failure, and flooding.
