Refrigerant Volume to Be Added
Refrigerant volume to be added is calculated according to outdoor unit installation manual.
Be sure to add refrigerant measuring by a scale.
If the added refrigerant volume is inadequate (too much or insufficient), the compressor
malfunction will be caused. Be sure to calculate the refrigerant volume carefully.
The service man should write down the piping length and the added refrigerant volume
in the nameplate, which is on the electric control box cover of outdoor unit, for
diagnosing the compressor and refrigeration circulation malfunction.
CAUTION
The refrigerant refrigerant charge volume for the unit is based on using a 5m connecting
pipe. If the connecting pipe's length is longer than 5m, it is advisable to charge
additional refrigerant for the unit in order to achieve better operation.

Please refer to the following figures to install.
The following figure only shows the assembly relationship of the indoor unit ,outdoor
unit and refrigerant pipes.
NOTE
The throttle subassembly has been installed in the outdoor unit..
Use two spanners to connect the pipe with indoor/outdoor pipes to avoid the copper pipe cracking.
Please pay attention to the connection orientation when connecting.
Use a vacuum pump, to vacuum from the gas side refrigerant adding mouth of the outdoor
unit.
Dont use the refrigerant of the outdoor unit to do the vacuum. (A certain volume of refrigerant
had been added into the outdoor unit in factory.)
Air and moisture remains inside the refrigeration system, may has the following bad effects:
Rise of pressure inside the refrigeration system;
Decrease of cooling (or *heating) effect;
Moisture frozen and blocking the refrigeration system;
Rusting of certain parts of the system
After connecting the indoor and outdoor units , it is necessary to exhaust the air inside the
pipes completely as follows:

Air Purging
1.Location in the following places may cause malfunction of the machine. (If unavoidable,
please consult your local dealer)
a. A place where there is flammable gas leakage.
b. There is salty air surrounding(near the coast).
c. There is caustic gas(the sulfide, for example) existing in the air (near a hot spring).
d. A place where can not bear the weight of the machine.
e. In kitchen where it is full of oil gas
f. There is strong electromagnetic wave existing.
g. There is acid or alkaline liquid evaporating.
h. A place where air circulation is not enough.
I.The appliance shall not be installed in the laundry
