Charging Refrigerant
1. Connect the manifold gauge to the charging valve and
evacuate the system.
2. Connect the center hose of the gauge to the refrigerant
tank.
3. Open the high pressure valve and charge the system with
350g of refrigerant.
4. Close the high pressure valve and start the engine and run
the compressor.
Notice
Never open the high pressure valve when the compressor
is running. Refrigerant gas will be charged reverse.
5. Slowly open the low pressure valve and charge the system
with refrigerant.
Standard650 - 750 g
6. Close the low pressure valve after charging.
Notice
Checking the pressure through the sight glass is impossible
by applying & R-134a.
7. Stop the engine and disconnect the manifold gauge from
the system.
Operation Check
1. Place a dry bulb thermometer to the front duct.
2. Place a psychrometer close to the inlet of the cooling unit
(under the glove box).
3. Run the engine at 1,500 rpm.
4. Set the blower switch at ‘HI’ and A/C switch ‘ON”.
5. Set the temperature control lever at ‘COOL’.
6. Set the air flow control at ‘REC’.
7. Check that air conditioning system is stabilized.
