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
09
Please read thoroughly all of the instrucitons before installing or
13
operating the unit.
15
Following safety symbols are very important, always read and obey
all safety symbols:

CAUTION
WARNING
DANGER
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, lables, or the data label 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.
Never use a flammable spray such as hair
spray, lacquer paint near the unit.
It may cause a fire.
If the supply cord is damaged, it must be
replaced by the manufacturer or its service
agent or a similarly qualified person.
