●Screw the support of the heat
exchanging board and fix the board
onto the chassis.
●Put the heat exchanging board
based on the position of the suction
and discharge pipes and weld the
pipes with the heat exchanging
board.
●During welding, charge nitrogen
into the pipes. The pressure should
be controlled within 0.5±0.1 kgf/cm2
(relative pressure).
Note: Avoid nearby parts from being
burnt during welding.
●Check various parts and connecting
lines.
●
If no problem is found, hook the
front panels and tighten the screws.
