REFRIGERANT RECOVERY, EVACUATION AND CHARGING
WARNING:

Your eyes should not be exposed to refrigerant (liquid).
Any liquid Refrigerant-134a escaping by accident shows a temperature as low as approx. ± 6C
(42.8F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause a seri-
ous injury. To protect your eyes against such accident, it is necessary to always wear goggles. Should
it occur that HFC-134a (R-134a) strikes your eye(s), consult a doctor immediately.
± DO NOT USE YOUR HAND TO RUB THE AFFECTED EYE(S). INSTEAD, use quantities of fresh cold
water to splash it over the affected area to gradually raise temperature of such area above freezing
point.
± Obtain proper treatment as soon as possible from a doctor or eye specialist.

Should the HFC-134a (R-134a) liquid come into contact with your skin, the affected area should be
treated in the same manner as when skin is frostbitten or frozen.

Refrigerant must not be handled near where welding or steam cleaning is performed.

Refrigerant should be kept at a cold and dark place. It should never be stored where a high tempera-
ture is anticipated, e.g. where exposed to direct sun light, close to fire or inside vehicle (including
trunk room).

Avoid breathing fumes produced when HFC-134a (R-134a) is burned. Such fumes may be hazardous
to health.

CHARGING
CAUTION:

ALWAYS CHARGE THROUGH LOW PRESSURE-SIDE of A / C system at after the initial charging is per-
formed 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 direc-
tions 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 40C (104F) 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 refrig-
erant 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 ser-
vice container.
When charging refrigerant recovered by using the refrigerant and recycling equipment (when recycling
refrigerant), follow the procedure described in the equipment manufacturer's instruction manual.
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 eva-
cuating the system.
2) Connect Low-side hose (1) and High side hose (2) of the man-
ifold gauge set (3) in position. Thus open refrigerant container
valve (4) to purge the charging line.
3) Open the high-pressure side valve (6) and charge refrigerant to
system.
4) After a while, open the low-pressure side valve (5) and close the
high-pressure side valve (6).
WARNING:
Make sure that high pressure-side valve is closed se-
curely.
5) Start engine and keep engine speed at 1500 r / min. Then, oper-
ate air conditioning.
6) Charge A / C system with refrigerant in vapor state. At this time,
refrigerant container should be held upright.
