3-2-2(b) Purging the Unit
On delivery, the indoor unit is loaded with an inert gas.
All this gas must therefore be purged before connecting the assembly piping. To purge the inert gas, proceed as fol lows.
Unscrew the caps at the end of each pipe.
Result : All inert gas escapes from the indoor unit.
• To prevent dirt or foreign objects from getting into the pipes during installation, do NOT remove the caps completely until you are ready to connect the piping.

5-3 PCB Inspection
5-3-1 Cautions for Part Replacement
1 . The human body carries much static e l e c t r i c i t y. Before touching a part for re p a i r, replacement or the similar purpose, be sure to touch a grounded metallic portion by hand to let the static electricity go thro u g h the matallic portion to the earth.
Espectially when handling any micro computer or IC, carefully remove such static electricity before touching them.
2 . When repairing any part on a work bench, be sure to place an insulative sheet on the bench and always keep the sheet surface neat without any metal fragments. If any such fragment touches a part, a secondary t rouble will possibly be caused in the part.
3. B e f o re replacing any parts, be sure to turn o ff the power supply. If such replacement is done with the power supply kept on, an electric shock, short circuit or destruction of a part may re s u l t .
4. During replacement or repair of a part, c a refully handle it : The printed circ u i t b o a rd has fine lead wires (jumper wires) and glass-made parts (diode) on its substrate.
So if a circuit board is roughly handled, such lead wires and parts will be easily broken or damaged by bending or shock.
5 . When soldering the lead wires of any new part, be sure to polish them using an emery paper or the like before solding them.
Since the lead wires of any new part are c o v e red with an oxide film, solder cannot a d h e re to the lead wires if not polished.
6 . When soldering any part, care should be e x e rcised not to apply any high-wattage soldering iron to the part for a long time.
Some parts are of so low a heat re s i s t a n c e that they may be broken or have the p roperties changed if a soldering iron is so applied (Otherwise, the pattern may possibly be separated and raised).
7. The heat of the soldering iron should be t r a n s f e red to the entire object to be soldere d .
If the solder pieces are not well fused due to i n s u fficient transfer of the heat from the soldering iron, no satisfactory electrical continuity can be assured even if the s o l d e red objects appear well connected to each other.
8 . The solder used should be limited to a minimum. If excessive solder is used, it will cause inter-pattern contact, which may cause malfunction of the circ u i t .
5-3-2 Procedure
The parts should be replaced in the following pro c e d u re .
Check for any faulty part.
Detach the faulty part.
Replace it with a new part.
Check the operation of the new part.
The repair is completed.
