Kia Optima: General Safety Information and Caution
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 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 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 the components immediately to prevent
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 resum of 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
Check the new O-ring for damage (use only the specified) and lubricate by 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. |
