Choose a right heat pump unit
2.1 Based on the local climate condition, construction features and insulation level,
calculate the required cooling(heating) capacity per square meter.
2.2 Conclude the total capacity which will be needed by the construction.
2.3 According to the total capacity needed, choose the right model by consulting the heat.
Pump features as below:
1. Heat pump features
Cooling only unit chilled water outlet temp. at 5-15 , maximum ambient temp. at
43 .
Heating and Cooling unit for cooling chilled water outlet temp. at 5-15 ,maximum
ambient temp. at 43 . For heating, warm water inlet temp. at 40-50 , minimum ambient
temp. at -10 .
2. Unit application
Air source water chiller and heat pump is used for house, office, hotel, and so forth,
which need heating or cooling separately, with each area need to be controlled.
3 Installation place
The unit can be installed on any place outdoor which can carry heavy machine such
as terrace, housetop, ground and so on.
The location must have good ventilation.
The place is free from heat radiation and other fire flame.
A pall is needed in winter to protect the heat pump from snow.
There must be not obstacles near the air inlet and outlet of the heat pump.
A place which is free from strong air blowing.
There must be water channel around the heat pump to drain the condensing water .
There must be enough space around the unit for maintenance.
4 Installation method
The heat pump can be installed onto the concrete basement by expansion screws, or
onto a steel frame with rubber feet which can be placed on the ground or housetop.
Make sure that the unit is placed horizontally.
9
Installation
5 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.
6 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. Then connect the 3-signal wire plugs of the
wire controller and main controller.
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.

When the unit need to be hung up during installation, a 8
metres 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
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 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.
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.
Trial running
Start the heat pump by press "
or
" 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.
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.
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).
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.

Maintenance

Maintenance
Check the water supply and air vent frequently, to avoid lack of water or air in the water
loop. Clean the water filter in a certain period to keep good water quality. Lack of water
and dirty water can damage the unit. The heat pump will start the water pump per 72 hours
when it is not running, to avoid freezing.
Keep the unit in a place which is dry and clean, and has good ventilation. Clean the heat
exchanger in 1 or 2 month and keep good heat exchange rate and save energy.
Check each part of the unit and the pressure of the system. Replace the failure part if
there is any, and recharge the refrigerant if it is needed.
Check the power supply and the electrical system, make sure the electrical components
are good, the wiring is well. If there is any part failed with wrong action or smell, please
replace in time.
If the heat pump is not used for a long time, please drain out all the water in the unit and
seal the unit to keep it good. Please drain the water from the lowest point of the heat
exchanger to avoid freezing in winter. Water recharge and full inspection on the heat
pump is needed before it is restarted.
Please drain out the water in the super heater of the heat pump unit in winter, when the
super heater is not used.
The water loop of the heat pump MUST be protected from freezing in winter time. Please
pay attention to below suggestions. Nonobservance on below suggestion will invalid the
warranty for the heat pump.
(1) Please do not shut off the power supply to the heat pump in winter. When the air
temperature is below 0 , if the inlet water temperature is above 2 and below 4 , the
water pump will start for freezing protect, if the inlet water is lower than 2 , the heat
pump will run for heating.
(2) Use anti-freezing liquid (glycol water)
1) look for below table for the volume of the glycol water
2) the glycol water can be added into the system from the expansion tank of the water
loop.

Appendix 2
The installation explanation of automatic filled-water
1 When automatic filled-water valve is installed ,the arrowhead orientation of inlet water
must accord with the orientation of valve ;
2 Automatic filled-water has been adjusted in advance to 1.5bar
3 If readjust the pressure of inlet water, please operate as follows
* open the screw cap C
* If reduce the pressure of water supply, please unscrew the pressure to adjust the
screw(B)
* If increase the pressure of water supply, please screw down the pressure to adjust the
screw (B)
4 When the system need fill water at first, wrest the handle(A) of filled-water.Then the
handle(A) can return(close) when the system is full of water.
5 Automatic filled-water Valve need clean in a periodic time and then you must close the
tap, unscrew the plug(D),remove the inside filter net. Please assemble them again after
cleaning.
NOTICE There are two connections for water pressure meter in the central section of
automatic filled-water,where the water pressure meter can be connected directly and
display the set pressure. The screw cap(C) must be tweaked after adjusting the filledwater pressure.

Appendix 3
The installation explanation of the leakage pressure valve.
1 The action pressure of leakage pressure valve 'is more than 3bar(valve is open), but the
pressure can not be adjusted.
2 The valve will open automatically to make sure that the water loop of air-con system is
safe when the water pressure in the backwater side is higher than the set pressure.
