- Turn on the power supply to the heater at the circuit breaker.
- The digital display will illuminate.
6.2 Setting Temperature
- Use the digital touch screen to navigate the settings.
- Press the appropriate buttons (usually up/down arrows or a dedicated temperature button) to adjust the desired water temperature.
- The heater will automatically activate when the water temperature falls below the set point and deactivate once the set temperature is reached.
- To switch between Celsius (°C) and Fahrenheit (°F), locate the toggle option on the display and select your preferred unit.

7. Maintenance
Regular maintenance ensures the longevity and efficient operation of your pool heater.
7.1 Routine Checks
- Periodically inspect the heater for any signs of leaks, corrosion, or damage to the casing or connections.
- Ensure the area around the heater is clear of debris and allows for proper ventilation.
- Check water flow to ensure it is consistent and unobstructed. Clogged water inlets can trigger safety shutdowns.
7.2 Cleaning
- Wipe down the exterior of the heater with a soft, damp cloth. Do not use abrasive cleaners or solvents.
