0. BASIC OPERATION PRINCIPLE
As we know with our experience, the natural flow of heat, which
moves from a higher to a lower temperature source. The 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 times than input electricity power by
extracting the heat from ambient atmosphere in a free charge way
to Sanitary Hot Water, compare to the traditional water heater, such
as electric water heater or gas burner water heater, their efficiency is
normally less than 1, which means it will dramatically cut off the bill
of family daily SHW by the application of heat pump water heater,
following data will show more details.
Power consumption comparison under the same condition to heat 1
ton water from 15˚C to 55˚C
The equivalent heat load Q=CM(T1-T2)=1(kCal/kg*°C)
X1000(kg)*(55-15)(°C)=40000kCal=46.67kW*h

1. SAFETY INFORMATION
Please read thoroughly all of the instrucitons before installing or
operating the unit.
Following safety symbols are very important, always read and
obey all safety symbols:
CAUTION
You may be injured if you don't obey

don't obey instructions.
DANGER
You may be killed or seriously injured
immediately if you don't obey instructions.
WARNING
● The unit must be earthed effectively.
● A creepage breaker must be installed adjacent to the power
supply.
● Do not remove, cover or deface any permanent instructions,
labels, or the data labels from either the outside of the unit
or inside of unit panels.
● Ask qualified person to 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 instead of doing by yourself.
Improper installation may result in water leakage, electric
shock or fire.
● Electric connection work should obey the instructions of
local power company, local electric utility and this manual.
● Never use the wire and fuse with wrong rated current,
otherwise unit may break down and cause fire furthermore.
● Do not insert fingers, rods or other objects into the air inlet
or outlet.
When the fan is rotating at high speed, it will cause injury.
● Never use a flammable spray such as hair spray, lacquer
paint near the unit.
It may cause a fire.
