Vehicle Damage Warnings

NOTE: When servicing air conditioning system, the following rules must be observed.

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).
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.

WIRING
1. Disconnect battery negative terminal.
2. Connect wire connectors securely.
3. When routing wire harness through panel hole, previously insert rubber bushing into hole for its protection.
4. Use vinyl tape or original clamps to connect air conditioning wire harness to main wire harness.
5. If original harness has been disconnected or removed while servicing, replace it to a proper position.
6. During installation, be careful not to pinch original air conditioning wire harnesses.
7. When adding wires to wire harness by soldering, use wires with the same diameter and tape for each connection.
8. Keep wire harness away from any moving components and high temperature.
9. Keep connecting portions away from fuel lines.
10. Make sure wire harness contacts no sharp edges or corners.

PIPING
1. Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.
2. 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.
3. When connecting hoses and pipes, apply a few drops of refrigerant oil to seats of coupling nuts and O-ring.
4. When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
5. Be specially careful for direction of receiver/dryer. (Inlet-side has the "IN" mark.) Receiver/dryer inlet fitting must be connected to pipe from condenser outlet fitting.
6. Tighten flared nuts according to Table of Tightening Torque as shown:

Tightening Torque (Flared Nut Used for)
1/4 inch pipe: 13 Nm (1.3 kg.m, 9.5 lb.ft)
8mm pipe: 13 Nm (1.3 kg.m, 9.5 lb.ft)
3/8 inch pipe: 25 Nm (2.5 kg.m, 18.0 lb.ft)
1/2 inch pipe: 35 Nm (3.5 kg.m, 25.5 lb.ft)
5/8 inch pipe: 45 Nm (4.5 kg.m, 32.5 lb.ft)

7. Route drain hose so that drained water does not make any contact to vehicle components.

HANDLING REFRIGERANT HFC-134a (R-134a)
1. When handling refrigerant, always wear goggles to protect your eyes.
2. Avoid you direct contact to liquid refrigerant.
3. Do not heat refrigerant container higher than 40 °C (100 °F).
4. Do not discharge refrigerant into atmosphere.
5. Do not allow liquid refrigerant to touch bright metals. Refrigerant combined with moisture is corrosive and will tarnish surfaces of bright metals including chrome.
6. After recovering refrigerant from system, the amount of compressor oil removed must be measured and the same amount added to the system.

WARNING:
Should refrigerant 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 R-134a get on your skin, such affected part should be treated in the same manner as when skin is frostbitten or frozen.

REFRIGERANT RECOVERY
When discharging refrigerant out of A/C system, always recover it by using refrigerant recovery and recycling equipment. Discharging refrigerant R-134a into atmosphere would cause adverse effect to environments.

NOTE: When handling recovery and recycling equipment, be sure to follow the instruction for the equipment.
