Debugging and running
5.1 Confirm the project before running
◆
Unit power supply. Be sure to have the same power source as the product nameplate.
◆
The circuit connection of the unit. Check the wire diameter and wiring of the power supply wire, and
the ground wire is firmly connected. Check if the linkage of the pump or the like is properly
connected.
◆
Water pipes and pipes. Water pipes and pipes must be flushed at least two or three times to ensure
cleanliness without any contaminants.
◆
Check the water circulation system. Check that the water volume is sufficient, that the air is drained,
and that there is no leakage.
◆
When powering on for the first time or after a long time of shutdown, the power must be turned on in
advance to heat the crankcase for at least 2 hours.
◆
The water filter is installed in place as required, and there is no pollutant in the water filter.
◆
Water flow switch, the pump overload has been linked with the unit, and the drain valve has been
installed in place.
