GENERAL INFORMATION
ELECTRICAL PARTS
Before removing and inspecting the electrical parts, set the ig-
nition switch to the LOCK position and disconnect the nega-
tive (-) terminal cable from the battery .
COOLING SYSTEM
1 . WHEN HANDLING REFRIGERANT (R-12),
FOLLOWING PRECAUTIONS MUST BE OBSERVED;
(a) Do not handle refrigerant in an enclosed area or near
an open flame.
(b) Always wear eye protection .
(c) Be careful that liquid refrigerant does not get in you
eyes or on your skin .
If liquid refrigerant gets in your eyes or on your skin ;
•
Do not rub.
•
Wash the area with lots of cool water .
•
Apply clean petroleum jelly to the skin .
•
Go immediately to a physician or hospital for pr
fessional treatment .
•
Do not attempt to treat yourself .
lk
2 . WHEN REPLACING PARTS IN REFRIGERANT LINE ;
(a) Discharge the refrigerant in the line slowly before
placement.
(b) Insert a plug immediately in disconnected parts
prevent the entry of moisture and dust .
(c) Do not leave a new condenser or receiver, etc ., ly
around with the plugs removed .
(d) Discharge the refrigerant from the charging
before installing a new compressor .
If the refrigerant is not discharged first, compress
will spray out with the refrigerant gas when the pl
removed .
(e) Do not use a torch for tube bending or length
operations.
If tubes are heated with a torch, a layer of ox
forms inside the tube, causing the same kind of tr
as an accumulation of dust .

3. WHEN HANDLING REFRIGERANT CONTAINER
(SERVICE CAN) ;
(a) The container must never be heated .
(b) Containers must be kept below 40°C (104°F)
(c) If warming a service can with hot water, be careful
that the valve on top of the service can is never im-
mersed in the water, as the water may permeate the
refrigerant cycle.
(d) Empty service cans must never be re-used .
4. WHEN A/C IS ON AND REFRIGERANT GAS IS BEING
REPLENISHED;
(a) If there is not enough refrigerant gas in the refriger-
ant cycle, oil lubrication will be insufficient and com-
pressor burnout may occur, so take care to avoid
this .
(b) If the valve on the high pressure side is opened, re-
frigerant flows in the reverse direction and could
cause the service can to rupture, so open and close
the valve on the low pressure side only .
(c) If the service can is inverted and refrigerant is
loaded in a liquid state, the liquid is compressed and
causes the compressor to break down, so the refrig-
erant must be in a gaseous state .
(d) Be careful not to load too much refrigerant gas, as
this causes trouble such as inadequate cooling, poor
fuel economy, engine overheating, etc .
5. WHEN USING GAS-CYLINDER TYPE GAS LEAK TESTER ;
(a) Since a naked flame is used, first make sure that
there are no flammable substances nearby before
using it .
(b) Be careful, as a poisonous gas is produced when re-
frigerant gas comes in contact with heated parts .
