Notes:
a. The rated cooling capacity data is measured under the following work condition: Indoor Temperature is 27ć DB,
1 9 ć WB. Outdoor Temperature is 35 ć DB.The rated heating capacity data is measured under the following work
condition: Indoor Temperature is 20ć DB. Outdoor Temperature is 7ć DB, 6ć WB.
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.

Schematic Diagram of Free Match Series Inverter Heat Pump Multi VRF System
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.

The following treatment should be taken under this circumstance:
a. Ensure that the smoke trap above cooker has enough capacity to obviate lampblack to prevent the indraft of the
lampblack by the air conditioner.
b. Keep the air conditioner far from the kitchen so that the lampblack would not be indraft by the air conditioner.
ƾ Important notice:
ƹ To guarantee the good performance, the unit must be installed by professional personnel according with this
instruction.
ƹ Please contact the local Gree special nominated repair department before installation. Any malfunction caused
by the unit that is installed by the department that is not special nominated by GREE would not deal with on time by the
inconvenience of the business contact.

CUATION ʽ
a. During the connection of the indoor unit and the refrigerant pipe, never pull any joints of the indoor unit by force;
otherwise the capillary pipe or other pipe may crack, which then would result in leakage.
b. The refrigerant pipe should be supported by brackets, that is, don’t let the unit withstand the weight of it.
CUATION ʽ
For the GMV multi VRF system, each pipe should be labeled to tell which system it belongs to avoid mistaken
inaccurate piping.
e. Installation of the Protection Layer of the Refrigerant Pipe
1) The refrigerant pipe should be insulated by the insulating material and plastic tape in order to prevent condensing
and leaking.
2) The joints of the indoor unit should be wrapped with the insulating material and no gas is allowed on the joint of
the indoor unit.
No gap
CUATION ʽ
After the pipe is protected well enough, never bend it to form a small angle; otherwise it would crack or break
f. Wrapping the pipe with tape:
1) Bundle the refrigerant pipe and electric wire together with tape, and separate them from the drain pipe to prevent
