Attention
4.6 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.
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.(See picture 2)
4.4 Installation occasions
4.5 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.
4.3 Transit
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
！

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.
Or please use forklift, since there is wood
chassis as package.
