HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
13) Loosen the center manifold hose connection on
the manifold gauge for a few seconds (if there is a
purge valve on the manifold gauge, push this in-
stead.) to purge air in the center hose using refrig-
erant pressure.
14) Open the high pressure and low pressure
valves to fill with refrigerant.
(1)
(1) Open
(2) Open
CAUTION:
When filling with the engine running, do not
open the high pressure side valve. Always fill
from the low pressure side.
15) When the gauge needle reaches approximate-
ly 200 kPa (1,500 mmHg, 59.1 inHg), close all
valves.
16) Using a leak tester, check the system for refrig-
erant leaks.
17) After confirming that there is no refrigerant
leak, fill the refrigerant to the specified amount.
18) If the HFC-134a supply container becomes
empty, close all valves, close the valve of the can
tap, and replace the empty container. After replac-
ing with a new HFC-134a supply container, perform
air purge and restart the filling process.
19) If the refrigerant filling efficiency worsens, close
all valves.
20) Confirm that the low pressure and high pres-
sure side valves are closed. Turn the A/C switch to
OFF and start the engine.
21) To prevent damage to the compressor, press
the ON-OFF of the A/C switch quickly several
times.
Refrigerant Charging Procedure
22) Set up the vehicle to the following status:
CAUTION:
When filling with the engine running, do not
open the high pressure side valve. Always fill
from the low pressure side.
• A/C switch ON
• Engine running at 1,500 rpm
• Blower speed setting to "HI"
• Temperature setting to "MAX COOL"
• Air inlet setting to "RECIRC"
• Window open
23) Open the low pressure side valve and fill with
refrigerant to the specified amount.
24) After filling with refrigerant, close all valves and
disconnect the hose from the service port.
