Product Information
The High Performance Spa Pump is designed for use in spas and requires a 120V
power source. It is important to follow the safety instructions and
installation tips provided in this manual to ensure proper usage and prevent
any electrical hazards or damage to
the pump.
This pump must be installed by a licensed electrician or qualified spa technician in accordance with the National Electrical Code and all applicable local codes and ordinances. Failure to do so may result in injury, death, or property damage.
The pump must be connected to a grounded circuit, properly bonded, and
protected by a Ground-Fault Circuit Interrupter (GFCI) to reduce the risk of
electrical shock. Always disconnect power to the pump at the circuit breaker
before servicing or inspecting the
pump.
It is essential to confirm the control system pump circuit voltage matches the pump’s voltage (110-120V) before installation. If unsure, consult with a professional.
Pump Wiring
2-Speed Setup:
- Turn off power before working on any electrical connections.
- Confirm pump circuit voltage matches pump (110-120V).
- Supply Red Wire: connect to Terminal H (high speed).
- Supply White Wire: connect to Terminal C.
- Supply Black Wire: connect to Terminal L (low speed).
- Supply Green/Ground Wire: connect with Ground Screw.
Note: Some spas may alternate the use of Red Wire for Low Speed and Black Wire for High Speed. In such cases, simply swap Red and Black wire terminal positions for correct high & low-speed control operation.
1-Speed Setup:
- Turn off power before working on any electrical connections.
- Confirm pump circuit voltage matches pump (110-120V).
- Supply Black Wire: connect to Terminal H.

Installation Tips
- Replace failing gasket seals or broken unions.
- Loosen the lowest union slightly after installation to bleed air and flood/prime the new pump, then retighten.
- Hand-tighten unions only, without a wrench.
- After installation is complete, operate the spa for a few minutes and observe for leaks or air locks.
