Installation

NOTICE: Port threads are: Internal - 2" NPT for direct
connection to pipe. External - 3-1/4" Buttress.
For quick disconnect pipe connections, use the 1-1/2" Slip
Half Union Kit included with the pump.
Only qualified, licensed personnel should install pump
and wiring.
Pump mount must:
Be located away from corrosive or flammable liquids.
Have enough ventilation to maintain air temperature at
less than the maximum ambient temperature rating (Max.
Amb.) listed on the motor model plate. If this pump is
installed in an enclosure/pump house, the enclosure
must have adequate ventilation and air circulation to
keep the temperature in the enclosure at or below the
motor's rated ambient temperature whenever the pump is
running.
Be solid - Level - Rigid - Vibration free. (To reduce vibra-
tion 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.
Fire and burn hazard. Modern motors run at
high temperatures. To reduce the risk of fire, do not allow
leaves, debris, or foreign matter to collect around the
pump motor. To avoid burns when handling the motor, let
it cool for 20 minutes before trying to work on it.

NOTICE: When connecting threaded pipe directly to
pump, use Teflon tape or Plasto-Joint Stik
nections. Do not use pipe dope; pipe dope causes crack-
ing in some plastics and may damage components in
piping system.
When connecting pipe to pump with union half, use
Teflon tape or Plasto-Joint Stik
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 additional layers of tape and remake the
connection.
NOTICE: 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 (included).
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 away from the
pump.
To avoid airlocking, slope suction pipe slightly upward
toward the pump.
NOTICE: To prevent flooding when removing pump for
service, all flooded suction systems must have gate
valves in suction and discharge pipes.

Hazardous Suction.
Can trap hair or body,
causing severe injury
or death.
• Do not block suction.
• Keep small children
