WARNING
Never connect unclean pipe to the unit!
If the unit is to idle for a long time, the water in the water system shall be drained to prevent the plate
heat exchanger being iced.
If the unit is to idle for a short time, the power-off is not allowed, because the unit has automatic
anti-freezing function. When the temperature in the outlet pipe is very low, the unit will automatically
operate for a period to maintain the temperature of the water system and prevent the water pipe from
being frozen, so the unit must be energized in winter. If the unit is not used in winter, drain the water from
the water system or fill such anti-freezing mixture as ethylene glycol and glycerol into the water system.
The water filter must be installed correctly; otherwise, the unit may be damaged. Additionally, the water
filter shall be regularly inspected for any blockage due to dirt.
