Installation
1. Install pump in sump pit with minimum diameter
of 10" (254mm) for models equipped with vertical
switches and 14" (356mm) for tethered float switch
models. Sump depth should be 18" (457mm) for
tethered models and 13" (330mm) for vertically
switched 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 This unit is not designed as a waterfall or fountain
pump, or for applications involving salt water or brine!
Use with waterfalls, fountains, salt water or brine will void
warranty.
Do not use where water recirculates.
Not designed for use as a swimming pool drainer.
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.
