This manual includes all the necessary information about installation, debugging,
discharging and maintenance. Please read this manual carefully before you open or
maintain the unit.
Read these operating and installation instructions carefully and keep them safe. Should
the equipment change hands, pass these instructions to the subsequent owner. Pass them
to the trained contractors for servicing purposes. Positioning, installation and
commissioning must be carried out by trained personnel working in accordance with these
operating and installation instructions.
When the product is delivered to the users, please check whether there is any damage on
the unit during transportation; If any please talk with the forwarder or the contractor.
If the heat pump unit can just be installed a while latter, please keep it free from damage,
rust or abrasion by following methods.
1. all the access like the water connections must be sealed correctly;
2. the unit must be free from sunshine, and placed under 45℃;
3. the unit must be free from heavy dust to avoid dirty on the evaporator;
4. the unit must be placed free from chaos to avoid accident;
The pictures and drawings in this manual are for your information only. The manufacturer
has the right to chance or improve the product when it is needed, without prior notification
to the users of this device.
1.Preface
It is vital that the below instructions are adhered to at all times to keep the warranty.
—The unit can only be opened or repaired by qualified installer or an authorised dealer.

The unit is directly secured to the cement base with the expansion bolts.
Use channel steel to make the installation base, place shockproof rubber pads on
the ground or the roof, and ensure that the unit is placed levelly.

Figure 1 Installation Schematic Diagram of Snow Shed
To ensure the proper functioning of the unit in cold
areas in winter, the snow shed must be installed
during the engineering installation.
Caution
5.6 Water Pipe Connection
Note the following items during connection of water inlet and outlet pipes:
`
Minimize the resistance of the water pipe outside the unit.
The entire piping system should be clean and free of dirt and rust to prevent pipe
clogging. Test for leakages after the pipes are installed to ensure that the entire
piping system is free of leakage, and then coat with the insulating layer.
The pipeline should be conducted with a pressure test separately, rather than
together with the air conditioning main engine.
An expansion water tank should be installed at the highest point of the water
distribution pipeline, where the highest point of the water level in the expansion water
tank is at least 0.5 meters higher than the water distribution pipe.
Flexible joints should be used between the unit interface and the field piping to
reduce the vibration spread to both buildings and equipment. Both the pipe and the
fittings must be independently supported, but should not be supported by the unit.
The thermometer and the pressure gauge should be installed at the water inlet and
outlet pipes of the unit to facilitate the inspection during operation.
Drainage interfaces should be installed at all low positions of the water system (the
unit has a drain port to facilitate drainage; interfaces will be added in other positions
on site) so that the water in the system will be completely drained if it is not used in
winter; automatic exhaust valves should be installed at all high positions so as to
facilitate to exhaust the air from the pipeline. No insulation is provided for both the
exhaust valves and the drain port for easy maintenance.
5.7 Electrical Wiring
Open the panel, and open the power line hole
Thread the power line through the hole and connect it to the power line terminal; and
the three-core control line of the remote controller shall be plugged with the three-core
signal line on the main board according to the wiring diagram.
For an external water pump, thread the power line of the water pump through the hole
and connect it to the water pump terminals.
If it is necessary to automatically control the auxiliary heat source, connect the control
output signal of the auxiliary heat source to the start switch of the auxiliary heat source.
If it is necessary to automatically control mode of the air conditioning terminal, connect
the mode control signal to the mode control switch on each indoor air conditioning
terminal.

When lifting is needed, use four sling wires
longer than 8m for lifting; during the lifting, use the
special lifting hole (hook) on the unit base. Pads
shall be provided at the contact between the
housing and the sling to prevent the damage to the
housing, as shown in Figure 2.
5.Installation
5.9Trial Operation
Check the piping system. Check whether the expansion water tank is filled with sufficient
water and whether the water supply for supplement is normal. Check whether the entire
piping system is full of water and whether the air is completely exhausted. Check
whether all valves in the system are opened. Check whether the pipelines are well
insulated.
Check the power distribution system. Check whether all power supplies have normal
voltage. Check whether screws of each power distribution part are locked, and whether
the power is distributed to the circuit according to the distribution wiring diagram. Check
whether the ground line is well connected.
Check the water chilling unit. Check whether all fastening screws and screws on the
mechanical parts of the unit are firm. Check whether there is any fault indication on the
operation lights on the outdoor control main board. Connect the pressure gauge to the
fluoridated inlet to detect the system pressure during operation.

When lifting is needed, use four sling wires
longer than 8m for lifting; during the lifting, use the
special lifting hole (hook) on the unit base. Pads
shall be provided at the contact between the
housing and the sling to prevent the damage to the
housing, as shown in Figure 2.
5.Installation
5.9Trial Operation
Check the piping system. Check whether the expansion water tank is filled with sufficient
water and whether the water supply for supplement is normal. Check whether the entire
piping system is full of water and whether the air is completely exhausted. Check
whether all valves in the system are opened. Check whether the pipelines are well
insulated.
Check the power distribution system. Check whether all power supplies have normal
voltage. Check whether screws of each power distribution part are locked, and whether
the power is distributed to the circuit according to the distribution wiring diagram. Check
whether the ground line is well connected.
Check the water chilling unit. Check whether all fastening screws and screws on the
mechanical parts of the unit are firm. Check whether there is any fault indication on the
operation lights on the outdoor control main board. Connect the pressure gauge to the
fluoridated inlet to detect the system pressure during operation.
5.9.1 Check prior to trial operation
13

5.Installation
Turn on the machine with on the remote controller, and then immediately
check whether the water pump operates normally; if it is normal, observe the water
flow switch and the water pressure gauge of the water system: when the water flow
switch is in the ON state, the water pressure gauge shall show the water pressure of
about 0.2MPa.
After the water pump has operated for some time, the compressor will start. Judge
whether there is any abnormal sound in the unit during operation with the sense of
hearing; if there is any abnormal sound, immediately cut off the power and check the
unit; if there is no abnormal sound, continue the operation and then note whether
the pressure of the refrigerating system is normal.
Check whether the input power and the current of the unit are consistent with the
performance data list in the Manual; in case of incompliance, stop the unit for check.
Adjust the water supply valve in each room, so that the temperature of each room
meets the use requirements.
Observe whether the outlet water temperature is normal.
Parameters of the remote controller have been set in the factory, and the user shall
not adjust it without permission.
