2 Attention for Installation
2.1 Precautions for R410A
 It is very strict that the refrigerant pipes should be clean and dry.

Th
e R410A is a mixed refrigerant, when adding the refrigerant to the unit, it must be
in its liquid state. If the refrigerant is in gas state, the composition has been changed and the
capability of the unit will decrease.

When the refrig
erant leaks out, please do not touch the leakage. Otherwise, it will result in
frostbite.
 It does not support to let a lot of refrigerant go into the ambient atmosphere, because it will
strengthen the green house effect. Otherwise, it will produce toxic gas when the refrigerant
contacts with the fire.
2.2 Precaution for Installation
 The unit is so heavy that it is more than 110kg, so more than two persons will be needed to
remove the unit. The package cannot bear it, so do not grasping it.

by the fins.
