ventilation distance
During transport, please keep the unit in an upright position. The unit
should not be laid down to prevent the inner parts of the device from
being damaged.
If the unit needs to be hung during installation, an 8-meter cable is
needed, and there must be a soft material between the cable and the
unit to prevent damage to the heat pump cabinet. (See picture 1)

4.9 Trial Run
Inspection before the Trial Run Trial Run
• Check the indoor unit and make sure that the pipe
connection is correctly installed and the relevant
valves are open.
• Check the water loop and ensure that the water
inside the expansion tank is enough, that the water
supply is good, and that the water loop is full of
water without any air. Also make sure that the
water pipe is well-insulated.
• Check the electrical wiring. Make sure that
the power voltage is normal, that the screws
are fastened, that the wiring is connected in
accordance with the diagram, and that the earthing
is connected.
• Check the heat pump unit including all of the
screws and parts of the unit to see if they are in
good order. Upon powering on, review the indicator
on the controller to see if there is any failure
indication. The pressure gauge can be connected to
the check valve to see the pressure of the system
during the trial run.
• Start the heat pump by pressing key on the
controller. Check if the water pump is running. If it is
running normally, there should be a reading of 0.2
MPa on the pressure meter.
• After the water pump runs for 1 minute, the
compressor will start. Listen if there is a strange
sound from the compressor. If an abnormal sound
occurs, please stop the unit immediately and check
the compressor. Otherwise if the compressor is
running normally, please look at 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 (or cold) water supply through each door
is good and meets the requirement of heating (or
cooling).
• Check if the outlet water temperature is stable.
• The parameters of the controller are set by the
factory. The user is not allowed to change them on
their own.
