lables, or the data label from either the outside of the unit or 

inside of unit panels.

●  Only qualified persons should perform the installation of this unit 

in accordance with local national regulations and this manual.

Improper installation may result in water leakage, electric shock 

or fire.

●   Ask qualified person for relocating, repairing and maintaining the 

unit.

Improper installation may result in water leakage, electric shock 

or fire.

●  Electric connection work should comply with the instructions of 

local power company, local electric utility and this manual.

●   Never use an incorrectly fuse rated, otherwise the unit may break 

down and risk of electrical fire.

●  Do not insert fingers, rods or other objects into the air inlet

    or outlet. The fan is rotating at high speed, and may cause injury.

●   Never use a flammable spray such as hair spray, lacquer paint

near the unit. It may cause a fire.

given supervision or instruction concerning use of the appliance 

by a person responsible for their safety. Children should be 

supervised to ensure that they do not play with the appliance.

NOTE

Above calculations are based on ideal conditions, the final 

amount will be different the actual running will vary with 

conditions, such as running period, ambient temperature, etc.

1.  BASIC OPERATION PRINCIPLE

We know from experience, the natural flow of heat, moves from a 

higher to a lower temperature source, a heat pump can transfer heat 

from a lower temperature source to a higher temperature source with 

high efficiency.

The advantage of a heat pump water heater is that it can supply more 

heat energy,  normally 3

:

1 times than input electricity power by 

extracting the heat from ambient atmosphere in a free-of charge way 

and transfer to Sanitary Hot Water. Compared to a traditional water 

heater, such as electric water heater or gas burner water heater, their 

efficiency is normally less than 1:1, which means you can dramatically 

cut off the bill of family daily SHW by the application of heat pump 

water heater, the following examples will show more details.

Power consumption comparison under the same condition to heat 1 

ton of water from 15˚C to 55˚C.
