• Please do not let any type of gas other than the specified refrigerant go into the refrigeration system;
• In case of refrigerant leakage during operation, please replace the gas. (Fill the refrigerant at the outdoor unit)

Select piping material
• Make sure both the internal surface and external surface of the pipes are intact and are free from harmful
contaminants such as sulphur, oxide, foreign matter, cutting powder, grease and water.
• Please use the following materials for refrigerant pipe.

• The branching pipe for the pipe must have refrigerant branching suite. For selection of refrigerant branching
suite and max. height drop between indoor units, please refer to the installation instructions or technical data
attached to the outdoor unit.

The high-pressure gas pipe, suction gas pipe, liquid pipe must be provided
with reliable thermal insulation. In the absence of thermal insulation, liquid
leakage may happen.
The outdoor unit is already filled with refrigerant.
To connect the pipes to connection kit or remove them from connection kit,
do use both spanner and torque wrench, as shown in the Fig.1.
Apply refrigerant oil to inside and outside of the flare. Screw it for 3 to 4
rounds with hands and then tighten it.
Determine the tightening torque. (Excessive tightening may damage the nuts
and hence cause leakage)
Check the connecting pipes for gas leakage and then fix the thermal
insulation, as shown in the in the Fig.2
Only use sealing gasket to wrap the part jointing between the gas pipe and
thermal insulation.
For pipe cutter and flare tool, please use R410A special tools.
