WORKING STANDARDS FOR PREVENTING BREAKAGE OF SEMICONDUCTORS
1. Scope
The standards provide for items to be generally observed in carrying and handling semiconductors in
relative manufactures during maintenance and handling thereof. (They apply the same to handling of
abnormal goods such as rejected goods being returned.)
2. Object parts
(1) Micro computer
(2) Integrated circuits (I.C.)
(3) Field effective transistor (F.E.T.)
(4) P.C. boards or the like to which the parts mentioned in (1) and (2) of this paragraph are equipped.
3. Items to be observed in handling
(1) Use a conductive container for carrying and storing of parts. (Even rejected goods should be handled in
the same way.)
(2) When any part is handled uncovered (in counting, packing and the like), the handling person must
always use himself as a body earth. (Make yourself a body earth by passing one M ohm earth
resistance through a ring or bracelet.)
(3) Be careful not to touch the parts with your clothing when you hold a part even if a body earth is
being taken.
(4) Be sure to place a part on a metal plate with grounding.
(5) Be careful not to fail to turn off power when you repair the printed circuit board. At the same time,
try to repair the printed circuit board on a grounded metal plate.

1. In quiet operation or stopping the running, slight flowing noise of refrigerant in the refrigerating cycle is
heard occasionally, but this noise is not abnormal for the operation.
2. When it thunders near by, it is recommend to stop the operation and to disconnect the power cord plug from
the power outlet for safety.
3. The room air conditioner does not start automatically after recovery of the electric power failure for prevent-
ing fuse blowing. Re-press START/STOP button after 3 minutes from when unit stopped.
4. If the room air conditioner is stopped by adjusting thermostat, or missoperation, and re-start in a moment,
there is occasion that the cooling and heating operation does not start for 3 minutes, it is not abnormal and
this is the result of the operation of IC delay circuit. This IC delay circuit ensures that there is no danger of
blowing fuse or damaging parts even if operation is restarted accidentally.
5. This room air conditioner should not be used at the cooling operation when the outside temperature is
below−10℃(14°F).
6. This room air conditioner (the reverse cycle) should not be used when the outside temperature is below
−15℃(5°F).
If the reverse cycle is used under this condition, the outside heat exchanger is frosted and efficiency falls.
7. When the outside heat exchanger is frosted, the frost is melted by operating the hot gas system, it is not
trouble that at this time fan stops and the vapour may rise from the outside heat exchanger.
