General safety information and caution
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 :
| • |
When removing refrigerant components from a vehicle, cap the
components immediately to prevent entry of moisture.
|
| • |
When installing refrigerant components to a vehicle, do not remove
the cap until just before connecting the components.
|
| • |
Complete the connection of all refrigerant tubes and hoses without
delay to prevent the A/C system from taking on moisture.
|
| • |
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.
|

| Refrigerant System Service Basics (R-1234yf) |
Refrigerant Identification
| • |
Do not mix HFO-1234yf (R-1234yf) in the vehicle with other refrigerant,
such as R-12, R-134a and etc.
|
| • |
Use only service equipment that is U.L-listed and is certified to meet
the requirements of SAE standards to recover and recycle R-1234yf from the
air conditioning system. Do not use service equipment for the other refrigerant,
such as R-12, R-134a and etc.
|
| • |
Verify what refrigerant is in the system if there is concern that the
system has been tampered with in any way and check the type and quantity
of refrigerant that shall be in the A/C system and potential issues arising
from accidental or intentional mixing of refrigerants.
|
| • |
Using an SAE certified refrigerant identification device is recommended
to prevent improper recovery and the resulting further spread of contaminated
refrigerant, which could potentially damage other A/C systems and service
equipment. Contaminated refrigerant (blend of more than one refrigerant
or non-system refrigerant) in recovery / recycling equipment could lead
to the potential contamination of more refrigerant.
|
| • |
Certain types of electronic leak detection devices (heated diode or corona
discharge) as well as motors, switches, and controls on recovery and recycling
machines, could generate sparks that could serve as ignition sources in
the presence of refrigerants classified as flammable (A2 or A3) by ASHRAE
standard 34 2006.
|
| • |
It is possible that the mixing of refrigerants in a A/C system can result
in higher-than-expected system pressures, system and component damage, diagnostic
errors and/or other potential hazards to people and environment.
|
| • |
In case other refrigerant is mixed, recover the contaminated refrigerant
in the A/C system and dispose it in accordance with all applicable national,
regional or local regulations. Clean inside the A/C system using the specialized
detergent and recharge new refrigerant.
|
Refrigerant Recovery
Use only service equipment that is U.L-listed and is certified to meet the requirements
of SAE standards to remove HFO-1234yf (R-1234yf) from the air conditioning system.
| • |
The electric compressor of a hybrid vehicle using high voltage
uses POE oil of high insulating performance.
|
| • |
Use a separate equipment (refrigerant retrieval/charging device)
for maintenance of a hybrid vehicle to prevent the PAG oil of a
general vehicle from flowing in upon retrieving/refilling the refrigerant.
|
|
| • |
Use the refrigerant retrieval/charge device exclusively used
for the electric compressor to inject the designated refrigerant
(R-134a) and refrigeration oil (POE). If the refrigeration oil (PAG)
for the ordinary car is injected, the compressor may be damaged
or a safety-related accident may occur.
