2.3. Daily Maintenance and Winterizing
2.3.1. Daily Maintenance
⚠️ Please don't forget to cut off power supply of the heat pump.
- Please clean the evaporator with household detergents or clean water. NEVER use gasoline, thinners, or any similar fuel.
- Check bolts, cables, and connections regularly.
2.3.2. Winterizing
In winter season when you don't swim, please cut off power supply and drain water out of the heat pump. When using the heat pump under 2℃, make sure there is always water flow.
❗Important: Unscrew the water union of the inlet pipe to let the water flow out. When the water in the machine freezes in winter season, the titanium heat exchanger may be damaged.
