8. Start the engine.
9. Operate the air conditioner and set at the lowest
temperature (MAX. COOL).
10. Fix the engine speed at 1,500 r/min.
11. Tighten the handle of the adaptor valve (valve open),
and replenish refrigerant while checking the quantity
through the sight glass.
Caution
If the service can is inverted, liquid refrigerant may
be draw into the compressor damaging it by liquid
compression. Keep the service can upright to ensure
that refrigerant is changed in gas state.
12. After replenishing is completed, turn the handle of the
adaptor valve all the way back (valve close), and remove
the quick joint.
NOTE
When there is remainder of refrigerant in the service can,
keep it for next use with the charge value and the valve
of the adaptor valve being closed.
DISCHARGING SYSTEM
Use the refrigerant recovery unit to discharge refrigerant gas
from the system.
NOTE : Refer to the Refrigerant Recovery and Recycling
Unit Instruction Manual for operation of the unit.
REFILLING OF OIL IN THE A/C SYSTEM
Too little oil will provide inadequate compressor lubrication
and cause a compressor failure. Too much oil will increase
discharge air temperature.
When a compressor is installed at the factory, it contains
130 cm
3of refrigerant oil. While the A/C system is in operation,
the oil is carried through the entire system by the refrigerant.
Some of this oil will be trapped and retained in various parts
of the system.
When the following system components are changed, it is
necessary to add oil to the system to replace the oil being
removed with the component.
