Honda HR-V: General Information
A/C SERVICE TIPS AND PRECAUTIONS
![WARNING](images/books/1097/index.26.png)
- Compressed air mixed with the R-134a forms a combustible vapor.
- The vapor can burn or explode causing serious injury.
- Never use compressed air to pressure test R-134a service equipment or
vehicle air conditioning systems.
![CAUTION](images/books/1097/index 227.png)
- Air conditioning refrigerant or lubricant vapor can irritate your eyes,
nose, or throat.
- Be careful when connecting service equipment.
- Do not breathe refrigerant or vapor.
The air conditioning system uses HFC-134a (R-134a) refrigerant and
polyalkyleneglycol (PAG) refrigerant oil.
If accidental system discharge occurs, ventilate the work area before resuming
service.
R-134a service equipment or vehicle air conditioning systems should not be
pressure tested or leak tested with
compressed air.
Additional health and safety information may be obtained from the refrigerant
and lubricant manufacturers.
- Always disconnect the negative cable from the 12 volt battery whenever
replacing air conditioning parts.
- Keep moisture and dirt out of the system. When disconnecting any lines,
plug or cap the fittings
immediately; do not remove the caps or plugs until just before you reconnect
each line.
- Before connecting any hose or line, apply a few drops of refrigerant oil
to the O-ring.
- When tightening or loosening a fitting, use a second wrench to support
the matching fitting.
- When discharging the system, use an R-134a A/C automatic recovery,
recycle, recharge machine; do not
release refrigerant into the atmosphere.
