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.
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.
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
for making all threaded connec-
1
tions to the pump. Do not use pipe dope; pipe dope will cause stress cracking
in the plastic pipe and fittings.
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!
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!
Piping:
Use at least 1-1/4" 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 possible 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.
