INSTALLATION
Installation and wiring of pump should only be done by qualified, licensed
personnel.
Pump mount must:
Be Solid - Level - Rigid - Vibration free. (To reduce vibration and pipe
stress, bolt pump to mount.)
Be installed with pump suction inlet below water level at all times (this al-
lows pump to prime).
Be installed with pump discharge below water level at all times (to avoid
trapped air in discharge line).
Allow discharge line to be level or slope slightly up to heater, spa, or pool.
Have adequate drainage to prevent flooding.
Be protected from excess moisture.
Allow adequate access for servicing pump and piping.
Ventilation:
Provide adequate ventilation to prevent motor overheating.
For continuous running, motor hot air exhaust must be able to escape motor
compartment.
Piping:
Use flexible or rigid PVC pipe for connections to pump.
Suction/discharge piping gate valves will allow removal for servicing.
Use at least 1-1/2" IPS pipe.
Fittings restrict flow; for best efficiency use fewest possible fittings.
Pump will not prime if suction pipe leaks.
Unions are provided. Use as follows for leak-free connections to pump:
1. ‘O’ Ring and sealing surfaces must be clean.
2. Assemble handtight only! (NO WRENCHES!)
3. NO pipe compound or Teflon tape on unions.
4. Bond pipe to unions with PVC cement.
Use PVC cement only in a well ventilated area away from flame;
FOLLOW MANUFACTURER‘S INSTRUCTIONS!
Spa Fittings:
Size and number of jets will have a major effect on jet action.
Typical installations use up to four 7/8" or 3/4" diameter jets or up to seven
1/2" diameter jets.
Spa fittings must meet International Association of Plumbing and
Mechanical Officials (IAPMO) standards. Use only non-entrapping suction
fitting or double suction.
