User Notice
◆ The total capacity of the indoor units which runs at the same time can not exceed 150% of
that of the outdoor units; otherwise, the cooling (heating) effect of each indoor unit would be poor.
◆ Switch the main power on 8 hours before starting the unit, helpful for a successful startup.
◆ It is a normal phenomenon that the indoor unit fan will still run for 20~70 seconds after the
indoor unit receives the “stop” signal so as to make full use of after-heat for the next operation.
◆ When the running modes of the indoor and outdoor units conflict, it will be indicated on
the display of the wired controller in five seconds and then the indoor unit will stop. In this case,
they can back to the normal condition by harmonizing their running modes: the cooling mode is
compatible with the dehumidifying mode and the fan mode can go with any other mode. If the
supply power fails when the unit is running, then the indoor unit will send the “start” signal to the
outdoor unit three minutes later after power recovery.
◆ During installation, the communication cable and the power cord must not be twisted
together but instead separated with an interval of at least 2cm; otherwise the unit is likely to run
abnormally.
◆ Cautions for the Debugging and Maintenance Personnel.
During debugging and maintenance, prior to the startup of the compressor make sure the
heating belt of the compressor has been energized for at least eight hours! Once the compressor is
started, it must be guaranteed that it works continuously for at least 30 minutes, otherwise it would
be damaged!
This series outdoor units are matched with the Multi system air
conditioner indoor unit under the same working conditons exported to European Union.
This product must not be disposed together with the domestic waste. This product

3 Working Principles of the Unit
Schematic Diagram of Multi system Series Inverter Heat Pump
M
Fig. 11 Schematic Diagram of Multi system Series Inverter Heat Pump
The outdoor and indoor units start to work once the power is switched on. During the cooling
operation, the low temperature, low pressure refrigerant gas from the heat exchanger of each
indoor unit gets together and then is taken into the compressor to be compressed into high
temperature, high pressure gas, which will soon go to the heat exchanger of the outdoor unit to
exchange heat with the outdoor air and then is turned into refrigerant liquid. After passing through
the throttling device, the temperature and pressure of the refrigerant liquid will further decrease and
then go the main valve. After that, it will be divided and go to the heat exchanger of each indoor
unit to exchange heat with the air which needs to be conditioned. Consequently, the refrigerant
liquid become low temperature, low pressure refrigerant gas again. Such a refrigeration cycle goes
round and round to achieve the desired cooling purpose. During the heating operation, the four-way
valve is involved to make the refrigeration cycle run reversely. The refrigerant radiates heat in the
heat exchanger of the indoor unit (so do the electric heating devices) and absorb heat in the heat
exchanger of the outdoor unit for a heat pump heating cycle so as to achieve the desired heating
purpose.
