2 Safety Considerations
Please read the following contents carefully before operating.
WARNING
■Once abnormality like burning
smell occurs, please cut off
the power supply immediately
and then contact with service
center.
If the abnormality still exists, the
unit may be damaged and
electric shock or re may result.
■Don't operate the unit with wet
hand.
Otherwise, it may cause electric
shock.
■Before installation,please
see if the voltage of local
place accords with that on
nameplate of unit and capacity
of power supply, power cord
or socket is suitable for input
power of this unit.
■Special circuit must be
adopted for power supply to
prevent re.
Do not use octopus multipurpose
plug or mobile terminal board for
wire connection.
■Be sure to pull out the power
plug and drain the unit and
water tank when unit is not in
use for a long time.
Otherwise, the accumulated dust
may cause overheating,fire or
freeze of water tank or coaxial
heater exchanger in winter.
■Never damage the electric
wire or use the one which is
not specied.
Otherwise, it may cause
overheating or re.
■Before cleaning please cut off
the power supply.
Otherwise, it may cause electric
shock or damage.
■The power supply must adopt
special circuit with leakage
switch and enough capacity.
■User can not change power
cord socket without prior
consent. Wiring working must
be done by professionals.
Ensure good earthing and
don't change earthing mode
of unit.

■Earthing: the unit must be
earthed reliably ! The earthing
wire should connect with
special device of buildings.
If not, please ask the qualified
personnel to install.
Furthermore, don't connect
earth wire to gas pipe, water
pipe, drainage pipe or any
other improper places which
professional does not recognize.
■Never insert any foreign
matter into uint to avoid
damage . And never insert
your hands into the air outlet
of the unit.
■Don't attempt to repair the unit
by yourself.
Improper repair may cause electric
shock or fire, so you should
contact the service center to
repair.
■Don't step on the top of the
unit or place anything on it.
There is the danger of fall of
things or people.
■Never block the air inlet and
outlet of unit.
It may reduce efficiency or cause
stop of the unit and even re.
■Keep pressurized spray, gas
holder and so on away from
the unit above 1m .
It may cause re or explosion.
■Please note whether the
installation stand is firm
enough or not.
If damaged, it may cause fall of
the unit and injury of people.
■Unit should be installed at the
place with good ventilation to
save energy.
■When there is not water in
water tank, never power the
unit on to run.
Notice!
(1) Before installation, please check if the adopted power is accordance with that listed on
nameplate, and check the safety of power.

4 Operating Principle of the Unit
DC Inverter Air to Water Heat Pump is composed of the unit,FCU and water tank. Operation
functions:
(1) Cooling;
(2) Heating;
(3) Water heating;
(4) Cooling +water heating;
(5) Heating+ water heating;
(6) Emergency mode;
(7) Quick water heating;
(8) Holiday mode;
(9) Forced Operation Mode;
(10) Silent mode;
(11) Disinfection mode;
(12) Weather-dependent Operation;
(13) Floor debugging
(14) Air removal of the water system
(15) Solar water heater
(16) Backup heat source
Cooling: in cooling mode, the refrigerant is condensed in the aluminum fin-copper tube and
evaporated in the plate heat exchanger. Via the heat exchange with water in the plate heat
exchanger, the temperature of water decrease and it releases heat while the refrigerant absorbs
heat and evaporates. With the help of wired controller, the outow temperature can meet the user’s
requirement. Through the control of valve, the low-temperature water in the system is connected
with indoor fan coil and underground pipe, and exchanges heat with the indoor air so that the indoor
temperature decreases to the required range.
Heating: in heating mode, the refrigerant evaporates in the aluminum fin-copper tube and
is condensed in the plate heat exchanger. Via the heat exchange with water in the plate heat
exchanger, the water absorbs heat and its temperature increase while the refrigerant releases heat
and is condensed. With the help of wired controller, the outflow temperature can meet the user’s
requirement. Through the control of valve, the high-temperature water in the system is connected
with indoor fan coil and underground pipe, and exchanges heat with the indoor air so that the indoor
temperature increases to the required range.
Water heating: in water heating mode: the refrigerant evaporates in the aluminum n-copper tube
and is condensed in the plate heat exchanger. Via the heat exchange with water in the plate heat
exchanger, the water absorbs heat and its temperature increase while the refrigerant releases heat
and is condensed. With the help of wired controller, the outflow temperature can meet the user’s
requirement. Through the control of valve, the high-temperature water in the system is connected
with the coil pipe of bearing water tank, and exchanges heat with the water in the water tank so that
the temperature of water tank increases to the required range.
Cooling + water heating: when cooling mode exists together with the water heating mode, the
user can set the priority of these two modes based on the needs. The default priority is heat pump.
That is under the default setting, if cooling mode exists together with the water heating mode, the
heat pump gives priority to cooling. In that case, water heating can only realized with e-heater of
the water tank. Inversely, the heat pump gives priority to water heating and switches to cooling after
nishing water heating.
Heating+ water heating: when heating mode exists together with the water heating mode, the

user can set the priority of these two modes based on the needs. The default priority is heat pump.
That is under the default setting, if heating mode exists together with the water heating mode, the
heat pump gives priority to heating. In that case, water heating can only realized with e-heater of
the water tank. Inversely, the heat pump gives priority to water heating and switches to heating after
nishing water heating.
Emergency mode: this mode is only available for heating and water heating. When the monobloc
unit stops due to malfunction, enter the corresponding emergency mode; as to heating mode, after
entering the emergency mode, heating can only be realized through e-heater .When the setting
outflow temperature or indoor temperature is reached, the e-heater will stop running; as to water
heating mode, the e-heater stops while the e-heater of water tank runs. When the setting temperature
or water tank is reached, the e-heater will stop running.
Quick water heating: in quick water heating mode, the unit runs according to the water heating
control of heat pump and the e-heater of water tank runs at the same time.
Forced Operation Mode: this mode is only used for refrigerant recovery and debugging for the
unit.
Holiday mode:this mode is only available for heating mode. This mode is set to keep indoor
temperature or leaving water temperature in a certain range, so as to prevent water system of the
unit from freezing or protect certain indoor articles from freezing damage. When the unit stops due to
malfunction, the two e-heaters of the unit will run.
Disinfection mode: in this mode, the water heating system can be disinfected. When starting up
the disinfection function and setting corresponding time to meet the requirement of disinfection mode,
the function will start. After the setting temperature is reached, this mode will terminate.
Weather-dependent Operation: this mode is only available for space heating or space cooling.
In Weather- dependent mode, the setting value (remote room air temperature or leaving water
temperature) is detected and controlled automatically when the outdoor air temperature is changed.
Quiet mode: Silent mode is available in cooling, heating and water heating mode. In silent mode,
the unit will reduce the running noise via automatic control.
Floor commissioning: this function is intended to preheat the oor periodically for the initial use.
Air removal of the water system: this function is intended to replenish water and remove air in
the water system to make the equipment run at the stabilized water pressure.
Solar water heater: when the condition for starting the solar water heater is satised, the solar
heater will start to heat the circulation water. Then the heated water will go to the water tank and
exchange heat with water in it. At any condition, the solar water heater will be given priority for startup
so as for energy conservation.
Backup heat source: when the outdoor temperature is lower than the set point for starting the
backup heat source and the unit is under the error condition and the compressor has stopped for
three minutes, then the backup heat source will start to supply heat or hot water to the room.
