INSTALLATION PRECAUTIONS(R32)
Important Considerations
1.
The air conditioner must be installed by professional
personnel and the Installation manual is used only
for the professional installation personnel! The
installation specifications should be subject to our
after-sale service regulations.
2.
When filling the combustible refrigerant, any of
your rude operations may cause serious injury or
injuries to human body and objects.
3.
A leak test must be done after the installation
completed.
4.
It is a must to do the safety inspection before
maintaining or repairing an air conditioner using
combustible refrigerant in order to ensure that the
fire risk is reduced to minimum.
5.
It is necessary to operate the machine under a
controlled procedure in order to ensure that any risk
arising from the combustible gas or vapor during
the operation is reduced to minimum.
6.
Requirements for the total weight of filled
refrigerant and the area of a room to be equipped
with an air conditioner (are shown as in the
following Tables GG.1 and GG.2)
