TROUBLESHOOTING
PROBLEM SYMPTOMS TABLE
Before replacing or repairing air conditioning components, first determine if the malfunction is due to the refrigerant
charge, air flow or compressor.
Use the table below to help you find the cause of the problem. The numbers indicate the priority of the likely cause of
the problem. Check each part in order. If necessary, replace these parts.
After correcting the malfunction, check the complete system to ensure that performance is satisfactory.

INSTRUCTIONS
WHEN HANDLING REFRIGERANT
1. R- 134a liquid refrigerant is highly volatile. A drop on the skin of your hand could result in localized frostbite. When
handling the refrigerant, be sure to wear gloves.
2. It is standard practice to wear goggles or glasses to protect your eyes, and gloves to protect your hands. If the
refrigerant splashes into your eyes, wash them with clean water immediately.
3. The R- 134a container is highly pressurized. Never leave it in a hot place, and check that the storage temperature
is below 52°C (126°F)
4. An electronic leak detector should be used to check the system for refrigerant leakage. Bear in mind that the R-
134a, upon coming into contact with flame, produces phosgene, a highly toxic gas.
5. Use only recommended the lubricant for R- 134a systems. If lubricants other than the recommended one used,
system failure may occur.
6. PAG lubricant absorbs moisture from the atmosphere at a rapid rate, therefore the following precautions must be
observed:
a. When removing refrigerant components from a vehicle, cap immediately the components to prevent from the
entry of moisture.
b. When installing refrigerant components to a vehicle, do not remove the cap until just before connecting the
components.
c. Complete the connection of all refrigerant tubes and hoses without delay to prevent the A/C system from taking
on moisture.
d. Use the recommended lubricant from a sealed container only.
7. If an accidental discharge in the system occurs, ventilate the work area before resuming service.
WHEN REPLACING PARTS ON A/C SYSTEM
1.Never open or loosen a connection before discharging the system.
2. Seal the open fittings of components with a cap or plug immediately to prevent intrusion of moisture or dust.
3. Do not remove the sealing caps from a replacement component until it is ready to be installed.
4. Before connecting an open fitting, always install a new sealing ring. Coat the fitting and seal with refrigerant oil
before making the connection.
WHEN INSTALLING CONNECTING PARTS
FLANGE WITH GUIDE PIN

FLANGE WITH GUIDE PIN
Check the new O - ring for damage (use only the specified) and lubricate it using compressor oil. Tighten the nut to
specified torque.

HANDLING TUBING AND FITTINGS
The internal parts of the refrigeration system will remain in a state of chemical stability as long as pure moisture- free
refrigerant and refrigerant oil are used. Abnormal amounts of dirt, moisture or air can upset the chemical stability and
cause problems or serious damage.
THE FOLLOWING PRECAUTIONS MUST BE OBSERVED
1. When it is necessary to open the refrigeration system, have everything you will need to service the system ready so
the system will not be left open any longer than necessary.
2. Cap or plug all lines and fittings as soon as they are opened to prevent the entrance of dirt and moisture.
3. All lines and components in parts stock should be capped or sealed until they are ready to be used.
4. Never attempt to rebind formed lines to fit. Use the correct line for the installation you are servicing.
5. All tools, including the refrigerant dispensing manifold, the gauge set manifold and test hoses, should be kept clean
and dry.
