CHARGING
1. INSTALL CHARGING CYLINDER
HINT:
When handling the charging cylinder, always follow the direc-
Push
Air tions given in the instruction manual.
(a) Charge the proper amount of refrigerant into the charging
cylinder.
(b) Connect the center hose to the charging cylinder.
Low Pressure CAUTION:
Service Valve
Do not open both high and low hand valves of manifold
gauge set.
(c) Open the valve of the charging cylinder.
(d) Press the valve core on the side of manifold gauge and
expel the air inside the center hose.

2. INSPECT REFRIGERATION SYSTEM FOR LEAKS
(a) Open the high pressure hand valve and the charge refrig-
erant.
(b) When the low pressure gauge indicates 98 kPa
(1 kgf/cm2, 14 psi), close the high pressure hand valve.
(c) Using a gas leak detector, check the system for any leak-
age.
If leaks are found, repair the faulty component or connection.
CAUTION:
Use the refrigerant recovery/ recycling machine to recover
the refrigerant whenever replacing parts.

3. CHARGE REFRIGERANT INTO REFRIGERATION
SYSTEM
If there is no leak after refrigerant leak check, charge the proper
amount of refrigerant into the refrigeration system.
CAUTION:
z Do not run the engine when charging the system
through the high pressure side.
z Do not open the low pressure hand valve when the
system is being charged with liquid refrigerant.
Low Pressure
(a) Open the high pressure hand valve fully.
Service Valve (b) Charge specified amount of refrigerant, then close the
high pressure hand valve.
HINT:
No bubbles in the sight glass indicates that the system is fully
charged.
(c) Partially charge the refrigeration system with refrigerant.
High Pressure (1) Start engine and race engine at 1,500 rpm.
Service Valve
(2) Set fan speed selector to "HI".
N13790 (3) Set temperature control to "MAX. COOL".
(4) Set air inlet control to "RECIRC".
(5) Fully open doors (Sliding roof: closed).
(6) Open the low pressure hand valve.
CAUTION:
Do not open the high pressure hand valve.
(d) Charge refrigerant until bubbles disappear and check the
pressure on the gauge through the sight glass.

HINT:
If the reading is 750 mmHg (30 in. Hg) close both hand valves
Low Pressure of the manifold gauge set and stop the vacuum pump.
Service Valve
Check the system for leaks and repair if necessary.
(e) Close both the high and low hand valves and stop the vac-
uum pump.
(f) Leave the system in this condition for at least 5 minutes
and check that there is no gauge indicator.
