Float Switch Installation

Models equipped with vertical switches require some
assembly. Models with tethered float switches are ready
for use. See below.
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 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.
