Overall information of the heat pump
The air source heat pump extracts heat from ambient air and transfer it to water. By
circulating the water, the energy is used to warm the house efficiently. Through the usage of
floor heating, the heat pump COP can be as high as 4.5
Compared with oil boiler, gas boiler and electrical heater, heat pump is the best solution with
high efficiency, safety and environment protect.
This air source heat pump use advanced heating tech-nology and intelligent control system,
to produce hot water at more than 55℃. So it can work with the floor heating pipe, the fan coil
or the radiator,and replace the boiler directly.
3.2.Features of the AIR HEAT PUMP
1, Save our planet---earth, by green technology
Heat pump transfer heat from air to the space for heating, so that there is no burning,
no waste, no dirty gas, thus maintain good environment for human and save earth from waste.
2, Serve people by high efficiency and money saving
The heat pump is driven by electricity, and annually average efficiency can be higher than 4.
By timer function, users can make use of the electric power at the low point of a day, thus save
money for every family.
3, Good for life with safe running
To use heat pump for heating can avoid electrical shot and burning, thus keep people free from
explosion or poisoning.
4, Easy operation
Heat pump is controlled and protected by micro-computor based contro-ller, the desired water
temperature is set according to real requirement.System protection program will guarantee the
unit to be running at hard environment.
In reverse, cooling is also available when it is needed.
3.1.Device description
In addition, the air heat pump can be used to provide hot water for sanitary use, like kitchen,
shower, etc.

4.2.Transit
When the unit need to be hung up during installation, a 8
meters cable is needed, and there must be soft material
between the cable and the unit to prevent damage to the
heat pump cabinet. (See picture 1)
WARNING
DO NOT touch the heat exchanger of the heat
pump with fingers or other objects！
Picture 1
When the heat pump is transported please keep the unit
stand up. The unit cannot be laid down, otherwise the
inner parts of the device may be damaged.
There must be enough space around the unit for maintenance.
The place is free from heat radiation and other fire flame.
There must be not obstacles near the air inlet and outlet of the heat pump.
There must be water channel around the heat pump to drain the condensing water .
A place which is free from strong air blowing.
The location must have good ventilation.
The unit can be installed on any place outdoor which can carry heavy machine such as
terrace, housetop, ground and so on.
A pall is needed in winter to protect the heat pump from snow.
4.3.Installation occasions
Or please use forklift, since there is wood chassis as package.

Installation
4.4. Water loop connection
Please pay attention to below matters when the water pipe is connected:
Try to reduce the resistance to the water from the piping.
The piping must be clear and free from dirty and blocks. Water leakage test must be
carried out to ensure there is no water leaking. And then the insulation can be made.
Attention that the pipe must be tested by pressure separately. DO NOT test it together
with the heat pump.
There must be expansion tank on the top point of the water loop, and the water level in
the tank must be at least 0.5 meter higher than the top point of the water loop.
The flow switch is installed inside of the heat pump, check to ensure that the wiring and
action of the switch is normal and controlled by the controller.
Try to avoid air stayed inside of the water pipe, and there must be air vent on the top
point of the water loop.
There must be thermometer and pressure meter at the water inlet and outlet, for easy
inspection during running.
The connection between the heat pump and the construction is better to be flexible type,
to avoid vibration transfer. The support to the water pipe must be separate, but not rely
on the heat pump unit
There must be drainage on the low points of the water system, and there is already drainage
on the chassis of the heat pump. The water in the system must be drain out during winter
if the heat pump is not running. And there must be air vent on the high point of the water
system to drive air of the water. Drainage and air vent need not to be insulated, in order to
maintain.

4.5.Installation space
Attention: Please make sure that the height of other stacked thing around the heat pump
should lower than our heat pump, and please keep distance between these two parts.
(1) when the heat pump is installed under basement, indoor/other confined space, please
pay attention to the air inlet/outlet:
for CH-HP07UMPNK，cycled air volume should no less than 3200m3/h;
≥500mm
≥800mm ≥1000mm ≥1000mm

4.6.Water tank selection
Water tank should with stainless steel for inner tank, outer tank can with
stainless steel or color steel, and there should be 50mm-100mm foam insulation
between outer and inner tank. The water tank structure as following:

Installation
Attention:
1) The height of Hot water supplying port should 80mm higher than that recycled water port;
The distance from recycled water port to the bottom of water tank is at least 100mm;
2) Please make sure that there is insulation for water tank to make sure that the
temp decreasing is no more than 5℃ after one day and night. And water tank should
meet the dust prevention and fungi-proofing standard of sanitary water.

4.7.Power supply connection
Open the front panel, and open the power supply access.
The power supply must go through the wire access and be connected to the power supply
terminals in the controlling box.
If the outside water pump is needed, please insert the power supply wire into the wire access
also and connect to the water pump terminals.
If an additional auxiliary heater is need to be controlled by the heat pump controller, the relay
(or power) of the aux-heater must be connected to the relevant output of the controller.
4.8.Cable and switch
The unit should use independent power supply, Wiring required by Table 6.1, Power supply
voltage must in line with rated voltage.
Power supply circuit must be equipped with an All-pole disconnect device have at least 3mm
contact opening distance.
The wiring must be completed by professional technicians in accordance with circuit diagram.
Power supply circuit must have earth wire, the earth wire of power should be connected with
external earth wire safely. And the external earth wire must be in order.
The creepage protection device must be settled in accordance with the relevant national
technical standards for electronic equipment.
The power wire and signal wire should be neatly arranged. High voltage wire and low voltage
wire must be separated and free from any interference, and they must be free from any pipe
and valves of the unit.
When all the wiring is completed, the power can only be connected after a double check.

17
4.9. Trial running
Inspection before trial running
Check the indoor unit, and make sure that the pipe connection is right and the relevant
valves are open .
Check the heat pump unit including all of the screws and parts of the heat pump to see if
they are in good order. When power on, review the indicator on the controller to see if
there is any failure indication. The gas gauge can be connected to the check valve to
see the high pressure(or low pressure) of the system during trial running.
Check the water loop, to ensure that the water inside of the expansion tank is enough, the
water supply is good, the water loop is full of water and without any air. Also make sure
there is good insulation for the water pipe.
Check the electrical wiring. Make sure that the power voltage is normal, the screws are
fastened, the wiring is made in line with the diagram, and the earthing is connected.
Trial running
When the water pump runs for 1 minutes, the compressor will start. Hear whether there is
strange sound from the compressor. If abnormal sound occurs please stop the unit and
check the compressor. If the compressor runs well please look for the pressure meter
of the refrigerant.
Then check whether the power input and running current is in line with the manual. If not
please stop and check.
Review whether the outlet water temperature is stable.
The parameters of the controller are set by the factory, it is not allowed to change then
by user himself.
Adjust the valves on the water loop, to make sure that the hot(cool) water supply to each
door is good and meet the requirement of heating(or cooling).
Start the heat pump by press " " key on the controller. Check whether the water
pump is running, if it runs normally there will be 0.2 MPa on the water pressure meter.
