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
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.

Risk of fire and burns . Can cause severe
injury, property damage or death. 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 PTFE pipe thread sealant tape to seal
connections. Do not use pipe dope because it causes
cracking in some plastics and may damage components
in piping system.
When connecting pipe to pump with union half, use
PTFE tape 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.
Thread sealant tape instructions:
• Use only new or clean PVC pipe fittings.
• Wrap male pipe threads with one to two layers of
PTFE 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 to 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.
