INSTALLATION
1. Install pump in sump pit with minimum diameter of
14”
(356mm).
Sump depth should be
18” (457mm).
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.
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. Do not use ordinary pipe joint
compound on plastic pipe as it can attack plastics.
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.
NOTE: If check valve is not equipped with an air bleed hole to
prevent airlocking pump, 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.
Can shock, burn or kill. 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. Secure power cords to the discharge pipe so they are out of the way
for proper float switch operation, prior to testing the unit.
