Air Conditioning System: Manual Type 7B-26
4) After a while, open the low pressure side valve (6)
and close the high pressure side valve (5).
WARNING
!
Make sure that high pressure side valve is
closed securely.
5) Start engine and keep engine speed at 1500 r/min.
Then, operate air conditioning at “DEF” or “DEF/
FOOT” air flow mode.
6) Charge A/C system with refrigerant. At this time,
refrigerant container (4) should be held upright.
7) Remove manifold gauge set as follows:
WARNING
!
High pressure side is naturally under high
pressure. So, care must be taken to protect
your eyes and skin.
a) Close low pressure side valve of manifold gauge
set. (The high pressure side valve is closed
continuously during the process of charging.)
b) Close refrigerant container valve.
c) Stop engine.
d) Using shop rag, remove charging hoses from
service valves. This operation must be
performed rapidly.
e) Put caps on service valves.
Replacement of refrigerant container in charging
procedure
When refrigerant container (1) is emptied, use the
following procedure to replace it with a new refrigerant
container (1).
1) Close low pressure valve.
2) Replace empty container (1) with a refrigerant
container which has been charged with refrigerant.
When using refrigerant container tap valve (2), use
the following procedure for replacement.
a) Retract needle (3) and remove refrigerant
container tap valve (2) by loosening its plate nut
(4).
b) Install the refrigerant container tap valve (2) to a
new refrigerant container (1).
3) Purge any air existing in center charging hose
When using refrigerant container tap valve, use the
following procedure to purge air.
a) Once fully tighten refrigerant container tap valve
(1), and then loosen (open) plate nut (2) slightly.
b) Open low pressure side valve (3) of manifold
gauge set (4) a little.
c) As soon as refrigerant comes out with a “hiss”
through a clearance between refrigerant
container and tap valve, tighten plate nut (2) as
well as low pressure side valve (3).
d) Turn handle of tap valve (1) clockwise so that its
needle is screwed into the new container to
make a hole for refrigerant flow.
Checking of A/C System for Refrigerant Leaks
Whenever a refrigerant leak is suspected in the system
or any service operation has been performed which may
result in disturbing lines or connections, it is advisable to
test for leaks.
Common sense should be used in performing any
refrigerant leak test, since the need and extent of any
such test will, in general, depend upon the nature of a
complaint and the type of a service performed on the
system.
