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 temperature 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.

1. Start evacuating then wait 20 minutes. Refer to Evacuating of A/C System.
2. Stop evacuating and wait 10 minutes, then check system for pressure tightness. Refer to Checking of A/C System for Pressure Leaks.

If manifold gauge shows abnormal conditions, inspect and repair connections, then go to Step 1).

3. Recharge A/C with refrigerant.
Charge proper amount of refrigerant (in gas form). Refer to Procedure of Charging.

Amount of refrigerant
H25 engine model: 500 ± 50 g (1.1 ± 0.11 lb, 17.64 ± 1.76 oz)
H27 engine model with dual A/C: 780 ± 30 g (1.72 ± 0.07 lb, 27.51 ± 1.06 oz)
H27 engine model with single A/C: 620 ± 30 g (1.37 ± 0.07 lb, 21.87 ± 1.06 oz)

4. Check system for refrigerant leaks and refrigerant charging quality.
5. Perform Performance Test of A/C System.
