Installation
1. Install pump in sump pit with minimum diameter of
14” (356mm) for tethered float switch models. Sump
depth should be 18” (457mm) for tethered models.
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.
NOTICE Do not use ordinary pipe joint compound on
plastic pipe. Pipe joint compound can weaken plastics.
4. Install discharge plumbing. Use rigid plastic pipe and
wrap threads with PTFE pipe thread sealant tape.
Hand tighten pipe into pump plus 1-1/2 turns.
Risk of flooding. Can cause personal injury
and/or property damage. 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 If your 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.
