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.

Above calculations are based on ideal conditions, the final

conditions, such as running period, ambient temperature, etc.
2. SAFETY INFORMATION
Please read thoroughly all of the instrucitons before installing or
operating the unit.
The following safety warnings are very important, always read and
obey all safety symbols:
WARNING
● The unit must be earthed effectively.
● This appliance must be installed in accordance to AS/NZS stan-
dards and the NZ Building code.
● A RCD breaker must be installed adjacent to the power supply.
● Do not remove, cover or deface any permanent instructions,
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.
