Operating Instructions
After successful installation and filling the hot tub, you can begin operating the heater unit.
- Power On: Once plugged in, the unit should power on. The control panel (if present on the unit or integrated with the hot tub's main control) will illuminate.

- Heating Cycle: The heater will automatically begin heating the water to the set temperature. The time required to reach the desired temperature will vary depending on the initial water temperature, ambient temperature, and hot tub volume.
- Filter Cycle: The heater unit often works in conjunction with the hot tub's filtration system. Ensure your hot tub's filter pump is operating correctly for efficient heating and water circulation.
