Note
1. Do not dispose Refrigerant in sealed space or near
flame.
2. Wear glasses to protect your eyes.
3. Do not let liquid Refrigerant contact with your eyes
or skin.
If liquid Refrigerant contacts with your eyes or skin:
(a) Wash the contacted part with much water.
Warning: do not knead your eyes or skin.
(b) Spread clean Vaseline on your skin.
(c) Go to doctor or hospital for special cure.
4. Forbid heating it or making it expose the flame.
5. Forbid dropping the Refrigerant tank or shake it
intensively.
6. Do not operate compressor when Refrigerant is lack.
If the Refrigerant in cooling system is lack, it will incur com-
pressor burned out for lacking lubrication. So it is necessary
to avoid.
7. Do not open the high pressure valve of filling instru-
ment package when compressor is working.
If opening the valve at this time, Refrigerant will flow back into
refrigerant tank to incur the tank will break. So only the low
pressure valve could be opened or closed.
8. Do not fill Refrigerant too much.
Too much refrigerant will make many problems such as lack
cooling degree, oil consumption, too hot engine and so on.
Inspection on automobile
1. Check the No.1 pressure switch.
(a) Control for electromagnetic clutch:
Check the function of pressure switch.
(1) Assembly filling instrument package.
(2) Connect the anode lead of OUM meter to No. 4 termi-
nal and connect cathode lead to No. 1 terminal.
(3) Liking that shown in figure. When refrigerant pressure
is changed, check the conduction between terminals.

2. Use filling instrument package to check the refrigerant pressure.
This is a type to use filling pressure meter to check the malfunction position. In following situations, read
the meter.

zSwitch is set up at inner air cycle, and the inlet temperature is 30-50°C.
zEngine runs at the speed of 1500 rpm.
zSet up the speed control switch of fan at “HI” position.
zTemperature control switch is set up at “COOL” position.
zA/C switch turns to “ON”.
zAutomobile door is opened completely.
