Overall Information of the Heat Pump
The air source heat pump extracts heat from ambient air and transfers itto 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 thebest
solution with high efficiency, safety and environment protect.
This high temperature air source heat pump uses advanced heating tech-nology
and intelligent control system to produce hot water at more than65 . So it can
work with the floor heating pipe, the fan coil or the radiator,and replace the boiler
directly.
2.2 Features of the high temperature heat pump
1. Save our planet---earth, by green technology
Heat pump transfers heat from air to the space for heating, so that there is no burning, no
waste, no dirty gas, which maintains good environment for human and saves 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 and save
money for every family.
3. Good for life with safe running
To use heat pump for heating can avoid electrical shot and burning and 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 run at hard environment.
In reverse, cooling is also available when it is needed.
2.1 Device description
In addition, the high temperature heat pump can be used to provide hot water for
sanitary use, like kitchen, shower, etc.

Installation and Maintenance
3.5 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.
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.
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 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.

water pump terminals.
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 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.
3.8 Cable and switch
Attention:
The unit should use independent power supply, Wiring required by T abl e 6.1, Power supply vol tag e mus t in line wi th
rated voltage.
Power supply circuit must be equipped with an All-pole disconnect device have at least 3mm contact opening
distance.
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 wiring must be completed by professional technicians in accordance with circuit diagram.
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.

3.9 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.
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 . Check whether the water pump is running, if it runs normally there
will be 0.2 MPa on the water pressure meter.

Installation and Maintenance
3.10 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.
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.
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.
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.
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.
Please drain out the water in the super heater of the heat pump unit in winter, when the super
heater is not used, in case it is heat pump with super heater.
