INSTALLATION
Only qualified, licensed personnel should install pump
and wiring.
Pump mount must:
Be solid - Level - Rigid - Vibration free. (To reduce vibra-
tion and pipe stress, bolt pump to mount.)
Install pump with suction port below water level (flooded
suction) only. Pump does not lift water.
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.

When connecting threaded pipe directly to
pump, use Teflon tape or Plasto-Joint Stik
1
to seal connec-
tions. Do not use pipe dope; pipe dope causes cracking
in some plastics and may damage components in piping
system.
When connecting threaded pipe to pump with union
half, use Teflon tape or Plasto-Joint Stik between pipe and
union adapter. Union collar to pump should be assem-
bled dry and hand-tight. Make sure O-ring is seated in
groove.

Pump suction and discharge connections have
molded in thread stops. DO NOT try to screw pipe in be-
yond 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.

If leaks occur, remove pipe, clean off old tape, rewrap
with one to two additional layers of tape and remake the
connection.

Support all piping connected with pump!
Piping:
Use at least 1-1/2" (38mm) pipe (use 2"(51mm) pipe if
possible). Increase size if a long run is needed. When
using 1-1/2" pipe, connect to pump with 1-1/2" to 2" (38
to 51mm) reducing adapter.
To avoid strains on the pump, support both suction and
discharge pipes independently. Place these supports near
the pump.
To avoid a strain left by a gap at the last connection, start
all piping at the pump and run pipe
aaw
waayy
from the pump.
To avoid airlocking, slope suction pipe slightly upward
toward the pump.
