When welding the refrigerant pipe, in order to prevent internal
oxidation of the pipe, nitrogen must be filled in. Otherwise, the
oxidized chips may block refrigerating circulatory system.

Snow protection facilities must be installed in the snowfall areas.
(See the right figure)
(in case the snow protection facilities are
incomplete, faults may occur). In order to prevent influence
caused by snow, set up raised pavilion, and install snow protec-
tion sheds at the air inlet and air outlet.
The refrigerant pipe adapter is located inside the outdoor unit.
So remove the right front board first.(three M5 screw)
When the pipe is connected from the front side, the pipe can be
led out through the right front board.
As shown in Fig.4-7, when brazing the indoor and outdoor
connective lines, pad a sheet metal under the valve avoids the
flame burning the chassis.
