Setup and Installation
Plumbing Connection
The SPA pump comes with 1.5-inch pipe connectors. It is crucial to use SCH40 1.5-inch PVC pipe for all plumbing installations to ensure proper fit and function. If using other pipe sizes, ensure a proper adapter is used, starting with the 1.5-inch connection at the pump.

Electrical Connection
For regions with a standard voltage of 110V, such as the United States and Canada, the pump requires one ground wire and two hot wires (L1, L2). Ensure that the wiring complies with local electrical standards to guarantee safe operation. It is recommended to use a 2P GFCI breaker. Select the appropriate breaker based on the power requirements of your system.

Operating Instructions
Circulation Pump Requirements
It is essential to use a circulation pump with a power rating of at least 1HP to ensure sufficient water flow for proper operation and heating. Using a pump with less than 1HP may result in inadequate water circulation and inefficient heating.

Water Flow and Heating Indicators
The pump system typically includes indicator lights for water flow and heating status. If the water flow indicator light is lit, it signifies that the water flow rate is normal. When the heating indicator light is lit, it means the heater is actively heating the water. Ensure both indicators are functioning correctly during operation.

Working Principle
The SPA pump operates by circulating water through a heating element within the circulation system. As water passes through this element, it absorbs heat, increasing its temperature. This continuous circulation ensures an even distribution of warmth throughout your spa or hot tub, maintaining a stable and comfortable temperature.

Maintenance
- Regularly inspect the pump and all plumbing connections for leaks or damage.
- Keep the pump area clean and free from debris to ensure proper ventilation and prevent overheating.
- Check electrical connections periodically for tightness and signs of corrosion.
- Consult a qualified technician for any complex repairs or internal component maintenance.
Troubleshooting
- No Power: Check the circuit breaker (GFCI) and ensure all electrical connections are secure.
- No Water Flow: Verify that the pump is primed, water levels are adequate, and there are no obstructions in the plumbing. Ensure the circulation pump is operating correctly and has sufficient power (>1HP).
- Insufficient Heating: Confirm the thermostat settings are correct and the heating indicator is lit. Check for proper water flow as insufficient flow can hinder heating.
- Unusual Noise: Disconnect power and inspect for any foreign objects in the pump impeller. If noise persists, contact support.
