Refrigerant Recovery, Evacuation and Charging
Operation Procedure for Charging A/C with Refrigerant
WARNING:
Your eyes should not be exposed to refrigerant (liquid).
Any liquid Refrigerant-134a escaping by accident shows a temperature as low as approx. –6 °C
(21.2 °F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause a
serious 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 temper-
ature 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.
Start evacuating
Charge proper amount of refrigerant
in gas form
Amount of refrigerant
Dual A/C model : 750±50g (1.65±0.11 lb, 26.45±1.76 oz)
Single A/C model : 500±50g (1.1±0.11 lb, 17.64±1.76 oz)

Inspect and repair connections Stop evacuating
Performance test
Check system for pressure tightness
Charge A/C with refrigerant
Check system for refrigerant leaks and
refrigerant charging quantity
20 minutes
Wait 10 minutes
If gauge shows abnormal conditions

AIR CONDITIONING (OPTIONAL) 1B-25
On-Vehicle Service
Precaution
When servicing air conditioning system, the following rules must be observed.
Piping
When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling
nuts and O-ring. 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 refrigerant 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.
CAUTION:
None of refrigerant, compressor oil and component parts is interchangeable between two types of
A/C: one using CFC-12 (R-12) and the other using HFC-134a (R-134a).
(For identification between these two types, refer to “REFRIGERANT TYPE” in this section.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A/C installed in the vehicle being serviced.
Use of incorrect one will result in leakage of refrigerant, damage in parts or other faulty condition.
NOTE:
Single A/C model is the same as SQ625 (H25 engine) model. Refer to the same section of the Service
Manual mentioned in FOREWORD of this manual.
