6. Maintenance and Inspection
To check the water supply device and the releaser often. You should avoid the condition of no water or air enter
into system, or that will influence unit's performance and reliability. You should clear the water filter regularly to
avoid unit's damage by filter's jam.
There should be dry, sanitary and ventilation around the units. To clean the side heating exchanger regularly for
keeping good heating exchanging and saving energy.
To check the operation of every process in the u nit, the operation pressure of the refrigerant system.
You should maintain or change it in time.
Please discharge all water in the water pump and water system lest freeze the water pump or water system.
You should discharge the water at the bottom of water pump if the units will stop for long time. And you
should check the units thoroughly and fill the system with water fully before power on the units again.
To check the power supply and cable connection often, there is abnormal action or bad smell about the electrical
component. If there is, please maintain or change it in time.

Water in temp.
Sensor failure
Coil1 sensor failure(Heating mode)
Temp. is too much
different between
water-in and water-out
High pressure protection
Flow switch failure
Communication failure
Reason
The sensor is open
or short circuit
Check or replace a new sensor
Water flow volume not
enough, water
pressure difference is
too low
resolution
Wire controller and The
PCB connection failure
Check the wire connection
No water/little water
in water system.
Check the water flow volume,
water pump is failure or not
Water out temp.
Sensor failure
The sensor is open
or short circuit
Check or replace a new sensor
The sensor is open
