4. Setup and Installation
Follow these steps for proper installation of your replacement jet pump. Ensure all safety precautions are observed before proceeding.
- Disconnect Power: Turn off the main power to your hot tub or spa system at the circuit breaker. Verify that no power is reaching the pump.
- Drain System: Drain the hot tub or spa completely to prevent water spillage during pump removal and installation.
- Remove Old Pump: Disconnect the plumbing unions from the old pump. Carefully disconnect the electrical wiring from the old pump, noting the connections for reference. Remove the old pump from its mounting.
- Transfer Drain Plug: Locate the drain plug on your old pump. It is crucial to transfer this drain plug to your new Wavemaster 7000 pump before installation. Ensure it is securely tightened to prevent leaks.
- Position New Pump: Place the new Wavemaster 7000 pump in the mounting location. This pump is designed for direct replacement of Watkins Part # 36675, requiring no modification to the mounting or plumbing.
- Connect Plumbing: Reconnect the plumbing unions to the 2-inch inlet and outlet ports of the new pump. Hand-tighten first, then use a wrench to ensure a snug, leak-free connection. Do not overtighten.
- Connect Electrical Wiring: This pump is 110V only. Connect the electrical wiring to the high-speed side of the pump. Refer to the wiring diagram on the pump motor label and your spa's electrical schematic for correct connections. Ensure all connections are secure and insulated.

5. Operating Instructions
After successful installation, follow these steps to operate your Wavemaster 7000 jet pump.
- Fill Spa: Refill your hot tub or spa with water to the recommended operating level.
- Check for Leaks: Before restoring power, visually inspect all plumbing connections for any signs of leaks. Tighten connections as necessary.
- Restore Power: Turn on the main power to your hot tub or spa system at the circuit breaker.
- Prime the Pump: Most spa systems have an automatic priming cycle. If your system does not, or if the pump does not prime automatically, consult your spa's owner's manual for manual priming procedures. Listen for the pump to draw water and begin circulating.
- Monitor Operation: Observe the pump during its initial operation. Check for unusual noises, vibrations, or leaks. Ensure water is flowing through the jets.
The pump will operate according to your spa's control system settings. Refer to your spa's owner's manual for specific instructions on adjusting jet functions and filtration cycles.
6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your pump.
- Inspect for Leaks: Periodically check plumbing connections for leaks. Address any leaks promptly to prevent damage.
- Clean Filter: Ensure your spa's filter cartridge is regularly cleaned or replaced according to your spa manufacturer's recommendations. A clogged filter can strain the pump.
- Winterization: If you live in an area prone to freezing temperatures, properly winterize your spa and pump to prevent freeze damage. This typically involves draining the pump and plumbing lines. Consult your spa's owner's manual for detailed winterization procedures.
- Motor Ventilation: Ensure the pump motor has adequate ventilation. Do not obstruct the motor's cooling fins.
- Electrical Connections: Annually, or as needed, inspect electrical connections for corrosion or looseness. Ensure they are clean and secure (with power disconnected).
