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.)
Allow pump suction inlet height to be as close to water
level as possible.
Allow use of short, direct suction pipe (To reduce fric-
tion 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.
To reduce the risk of fire, keep all leaves, debris, or other
foreign matter from collecting around pump motor.
Modern motors run at high temperatures. Do not touch
while running. If motor requires service, let it cool for 20
minutes before trying to work on it.
NOTICE:
Use Teflon tape or Plasto-Joint Stik
1
for making
all threaded
connections to the pump. Do not use pipe dope; pipe
dope will cause stress cracking in the pump.
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" IPS PVC pipe for pump suction.
Increase size if a long run is needed.
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.
Never use a suction pipe smaller than pump suction
connection. 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.
Fittings:
Fittings restrict flow; for best efficiency use fewest possi-
ble fittings.
Avoid fittings which could cause an air trap.
Pool fittings must conform to International Association of
Plumbing and Mechanical Officials (IAPMO) standards.
To reduce risk of suction entrapment, do not exceed the
rated flow rate of the suction fittings.
