Procedure Of Charging - Suzuki Baleno Manual

1B-10 AIR CONDITIONING (OPTIONAL)
1. Manifold gauge set
2. High pressure side (Delivery side hose)
3. Low pressure side (Suction side hose)

PROCEDURE OF CHARGING

1) Check to make sure that hoses are routed properly after eva-
cuating the system (see left figure).
2) Connect the manifold gauge set in position. Thus open refriger-
ant container valve to purge the charging line. Then open the
low pressure-side valve.
3) Start engine and keep engine speed at 1000 r/min. Then, oper-
ate air conditioning.
4) Charge A/C system with refrigerant in vapor state. At this time,
refrigerant container should be held upright.
5) When refrigerant container is emptied, use the following proce-
dure to replace it with a new refrigerant container.
a. Close low pressure valve.
b. Replace empty container with a refrigerant container which has
1. Needle
2. Plate nut
3. Refrigerant container
4. Handle
c. Purge any air existing in center charging hose.
1. "Hiss"
WARNING:
Make sure that high pressure-side valve is closed se-
curely.
been charged with refrigerant. When using refrigerant contain-
er tap valve, use the following procedure for replacement.
i) Retract needle and remove refrigerant container tap
valve by loosening its plate nut.
ii) Install previously-removed refrigerant container tap
valve to a new refrigerant container.
When using refrigerant container tap valve, use the following
procedure to purge air.
i) Once fully tighten refrigerant container tap valve and then
loosen (open) plate nut slightly.
ii) Open low pressure valve of manifold gauge set a little.
iii) As soon as refrigerant comes out with a "hiss" through a
clearance between refrigerant container and tap valve,
tighten plate nut as well as manifold gauge set low pres-
sure valve.
iv) Turn handle of tap valve clockwise so that its needle is
screwed into the new container to make a hole for refrig-
erant flow.
