9. Please install with leakage protection switch. Check whether a leakage protection switch of suitable power is
installed between the unit and the power supply, if the leakage protection switch is not installed, it may cause
electric shock or fire.
10. Check the water flow and pressure of the circulating water of the equipment when the equipment is at
normal use, it must be ensured to prevent the unit from being protected and running short of water.
11. Do not move the detector freely. The temperature detector must not be separated from the water tank
temperature detection blind pipe to avoid overheating of the unit heater and might cause the unit damaged.
12. The unit’s maintenance and repairing by non-professional technicians to repair or adjust the advanced
factory controlling setting of the unit by themselves are not allowed, please contact the local service providers or
distributors for the operation.
13. The fuse selection must match with the unit. It is forbidden to use corresponding fuse which is not suitable.
Otherwise it may cause system errors or cause a fire.
14. Prevent the unit from fire. Do not spray flammable spray directly to the unit, otherwise it may cause a fire
accident.
15. Please cut off the manual power switch immediately when an abnormality (with burnt smell) occurs, stop
any further operation, and contact the local service providers or distributors.
If the abnormal operation continues, it may cause electric shock or fire.
16. Emergency measures after out of water or electricity supplying,
In cold areas, please do not cut off the water and power supply to avoid freezing the heat exchanger and the
water circulation system. In the event of a power failure, please drain all the cold water out of the heat exchanger
and the whole water circulation system, otherwise the heat exchanger will be damaged by freezing and the unit
cannot be used normally.
It is recommended with a condensed water drain pipe installed during engineering installation to prevent a large
amount of condensate water from flowing to the ground during drainage and causing large areas of water to
accumulate.
