Notes:
a. The rated cooling capacity data is measured under the following work condition: Indoor Temperature is 27ćDB,
1 9 ćWB. Outdoor Temperature is 35 ćDB.The rated heating capacity data is measured under the following work
condition: Indoor Temperature is 20ćDB. Outdoor Temperature is 7ćDB, 6ćWB.
b. The data will change with the change of products. Refer to those parameters listed on nameplate.
c. Noise was tested in semi-silenced room, so the actual noise value will be a little higher for change of ambient.

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 refrigeration 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.

1 PRECAUTIONS FOR INSTALLATION
1.1 Precautions for Installation
Before installation, please ensure if the installing site, power ratings, possible operating range (pipe distance, height
difference between indoor and outdoor unit, power voltage) and installing space are correct and suitable. The outdoor unit
is general to all models according to its power.
ƹTo ensure correct installation, please make sure to read the Safety Considerations thoroughly before starting the
installation works.
ƹThe considerations stated below are classified into WARNING and CAUTION. Those that might cause

ƹTo install a large air-conditioning system in a small room, please make sure to take measures to prevent that the
refrigerant will not exceed the limit concentration in case of leakage. For the measures to prevent the refrigerant from
exceeding the limit concentration, please consult your dealer. If no proper measures, it might cause human suffocation in
case of refrigerant leakage.
ƹPlease install at a position that is strong enough to support the weight of machine. If the installing position is of
low strength, the machine may drop down and thus cause human injury.
ƹPlease carry out installation in accordance with the rules for preventing the typhoon or earthquake. The machine
may tip over if the installation does not comply with the requirements.
ƹThe electrical cabling shall be carried out by qualified electricians in accordance with the Safety Code for
Electrical Equipment, relevant local rules and the installation instructions. Make sure to use the special-purpose circuit. If
