INSTALLATION

Only qualified, licensed personnel should install pump and wiring.
Pump mount must:

Be solid - Level - Rigid - Vibration free. (To reduce vibration and pipe stress,
bolt pump to mount.)

Allow pump suction inlet height to be as close to water level as possible.
Pump will not lift water more than 10'(3m).

Allow use of short, direct suction pipe (To reduce friction losses).
Allow for gate valves in suction and discharge piping.
Have adequate floor drainage to prevent flooding.
Be protected from excess moisture.
Allow adequate access for servicing pump and piping.

NOTICE: When connecting threaded pipe directly to pump, use Teflon tape
or Plasto-Joint Stik1to seal connections. Do not use pipe dope; pipe dope
causes cracking in some plastics and may damage components in piping sys­tem.

When connecting pipe to pump with union half, use Teflon tape or Plasto­Joint Stik between pipe and union adapter. Union collar to pump should be
assembled dry and hand-tight.

NOTICE: Pump suction and discharge connections have molded in thread
stops. DO NOT try to screw pipe in beyond these stops.

Teflon Taping Instructions:

Use only new or clean PVC pipe fittings.
Wrap male pipe threads with one to two layers of Teflon tape. Cover entire

threaded portion of pipe.
Do not overtighten or tighten past thread stop in pump port!
If leaks occur, remove pipe, clean off old tape, rewrap with one to two addi-

tional layers of tape and remake the connection.
NOTICE: Support all piping connected with pump!
