CHARGING
CHARGING PROCEDURE
The initial charging of the A/C system is performed from the high
pressure side with the engine stopped.
And next, this method must be followed by charging from the low
pressure side with the engine running.
1) Check to make sure that hoses are routed properly after
evacuating the system.
2) Connect Low charging hose (1) and High charging hose (2)
of the manifold gauge set (3) in position. Thus open refriger-
ant container valve (4) to purge the charging line.
3) Open the high pressure side valve (5) and charge refrigerant
to system.
4) After a while, open the low pressure side valve (6) and close
the high pressure side valve (5).
5) Start engine and keep engine speed at 1500 r/min. Then,
operate air conditioning.
6) Charge A/C system with refrigerant in vapor state. At this
time, refrigerant container (4) should be held upright. CAUTION:
 Always charge through low pressure side of A/C system at after the initial charging is performed
from the high pressure side with the engine stopped.
 Never charge to high pressure side of A/C system with engine running.
 Do not charge while compressor is hot.
 When installing tap valve to refrigerant container to make a hole there through, carefully follow
directions given by manufacturer.
 A pressure gauge should always be used before and during charging.
 The refrigerant container should be emptied of refrigerant when discarding it.
 The refrigerant container should not be heated up to 40°C (104°F) or over.
 Refrigerant container should not be reversed in direction during charging. Reversing in direction
causes liquid refrigerant to enter compressor, causing troubles, such as compression of liquid
refrigerant and the like.
NOTE:
The air conditioning system contains HFC-134a (R-134a).
Described here is a method to charge the air conditioning system with refrigerant from the refrigerant
service container.
When charging refrigerant recovered by using the refrigerant and recycling equipment (when recy-
cling refrigerant), follow the procedure described in the equipment manufacturer’s instruction man-
ual.
WARNING:
Make sure that high pressure side valve is closed
securely.

7) When refrigerant container (1) is emptied, use the following
procedure to replace it with a new refrigerant container (1).
a) Close low pressure valve.
b) Replace empty container (1) with a refrigerant container
which has been charged with refrigerant. When using
refrigerant container tap valve (2), use the following proce-
dure for replacement.
i) Retract needle (3) and remove refrigerant container tap
valve (2) by loosening its plate nut (4).
ii) Install previously-removed refrigerant container tap valve
(2) to a new refrigerant container (1).
c) Purge any air existing in center charging hose
When using refrigerant container tap valve, use the follow-
ing procedure to purge air.
i) Once fully tighten refrigerant container tap valve (1), and
then loosen (open) plate nut (2) slightly.
ii) Open low pressure side valve (3) of manifold gauge set
(4) a little.
iii) 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).
iv) Turn handle of tap valve (1) clockwise so that its needle is
screwed into the new container to make a hole for refriger-
ant flow.
8) After the system has been charged with specified amount
(330 – 390 g) of refrigerant or when low pressure gauge (1)
and high pressure gauge (2) have indicated the following
specified amount, close low pressure side valve (3) on mani-
fold gauge set (4). At this time, look into the sight glass (5) of
condenser outlet pipe (6) and check that there are no bub-
bles (7) in it, which means that the system is fully charged.

REMOVING MANIFOLD GAUGE SET
When A/C system has been charged with a specified amount of refrigerant, remove manifold gauge set as fol-
lows :
1) Close low pressure side valve of manifold gauge set. (The high pressure side valve is closed continuously
during the process of charging.)
2) Close refrigerant container valve.
3) Stop engine.
4) Using shop rag, remove charging hoses from service valves. This operation must be performed rapidly.
5) Put caps on service valves.
LEAK TEST
Whenever a refrigerant leak is suspected in the system or any
service operation has been performed which may result in dis-
turbing 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.
LIQUID LEAK DETECTORS
There are a number of fittings and places throughout the air con-
ditioning system where a liquid leak detector solution may be
used to pinpoint refrigerant leaks.
By merely applying the solution to the area in question with a
swab, such as attached to the cap of a vial, bubbles will form
within seconds if there is a leak.
For confined areas, such as sections of the evaporator and con-
denser, an electronic (refrigerant) leak detector is more practical
for determining leaks.
Special tool
(A) : 09990 - 86011 WARNING:
High pressure side is naturally under high pressure. So, care must be used to protect your eyes and
skin.
WARNING:
 To prevent explosions or fires, make sure that there
are no flammables in the vicinity.
 When exposed to fire, the refrigerant turns into a poi-
sonous gas (phosgene). Do not inhale this gas.

ON-VEHICLE SERVICE
SERVICE PRECAUTION
When servicing air conditioning system, note the following instructions.
REFRIGERANT LINE
Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.
Keep internal parts of air conditioning free from moisture and dirt. When disconnecting any line from system,
install a blind plug or cap to the fitting immediately.
When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling
nuts and O-ring.
When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
Tighten flared nuts by the following specified torque.
Tightening torque
8 mm pipe : 13 N·m (1.3 kg-m, 9.5 lb-ft)
12 mm pipe : 23 N·m (2.3 kg-m, 16.6 lb-ft)
14.5 mm pipe : 33 N·m (3.3 kg-m, 23.8 lb-ft) WARNING:
Should refrigerant HFC-134a (R-134a) strike your eye(s), consult a doctor immediately.
 Do not use your hand to rub affected eye(s). Instead, use quantities of fresh cold water to splash it
over affected area to thus gradually raise its temperature above the freezing point.
 Obtain proper treatment as soon as possible from a doctor or eye specialist. Should liquid refriger-
ant HFC-134a (R-134a) get on your skin, such affected part should be treated in the same manner as
when skin is frostbitten or frozen.

TIRE
MOUNTING AND DISMOUNTING
Use a tire changing machine to mount or dismount tires. Follow equipment manufacturer’s instructions. Do not
use hand tools or tire irons alone to change tires as they may damage tire beads or wheel rim.
Rim bead seats should be cleaned with a wire brush or coarse steel wool to remove lubricants, old rubber and
light rust. Before mounting or dismounting a tire, bead area should be well lubricated with approved tire lubri-
cant.
After mounting, inflate to specified pressure shown on tire placard so that beads are completely seated.
Install valve core and inflate to proper pressure.
REPAIR
There are many different materials and techniques on the market to repair tires. As not all of these work on all
types of tires, tire manufacturers have published detailed instructions on how and when to repair tires. These
instructions can be obtained from each tire manufacturer.WARNING:
Do not stand over tire when inflating. Bead may break when bead snaps over rim’s safety hump and
cause serious personal injury.
Do not exceed specified pressure when inflating. If specified pressure will not seat beads, deflate, re-
lubricate and reinflate.
Over inflation may cause bead to break and cause serious personal injury.
