Operation Procedure for Refrigerant Charging

WARNING
!
• Your eyes should not be exposed to refrigerant (liquid).
Any liquid HFC-134a (R-134a) escaping by accident shows a temperature as low as approximately –
6 °C (21.2 °F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause
a serious injury. To protect your eyes against such accident, it is necessary to always wear goggles.
Should it occur that HFC-134a (R-134a) strikes your eyes, consult a doctor immediately.
– Do not use your hand to rub the affected eye(s). Instead, use quantities of fresh cold water to
splash it over the affected area to gradually raise temperature of such area above freezing point.
– Obtain proper treatment as soon as possible from a doctor or eye specialist.
• Should the HFC-134a (R-134a) liquid come into contact with your skin, the affected area should be
treated in the same manner as when skin is frostbitten or frozen.
• Refrigerant must not be handled near where welding or steam cleaning is performed.
• Refrigerant should be kept at a cold and dark place. It should never be stored where a high
temperature is anticipated, e.g. where exposed to direct sun light, close to fire or inside vehicle
(including trunk room).
• Avoid breathing fumes produced when HFC-134a (R-134a) is burned. Such fumes may be hazardous
to health.
Step
1 1) Replenish compressor oil referring to "Replenishing
Compressor Oil: Manual Type".
2) Start evacuating, and then wait 15 minutes referring to
"Evacuating of A/C System: Manual Type".
3) Stop evacuating, and then wait 10 minutes.
4) Check system for pressure leakage referring to
"Checking of A/C System for Pressure Leaks: Manual
Type".
Does gauge show normal condition?
2 1) Charge A/C system with refrigerant referring to
"Procedure of Charging: Manual Type".
Amount of refrigerant
500 ± 30 g (17.65 ± 1.05 oz)
2) Check system for refrigerant leaks referring to "Checking
of A/C System for Refrigerant Leaks: Manual Type", and
then perform "A/C System Performance Inspection".
Does A/C system operate properly?
Recovery
When evacuating A/C system, always recover
refrigerant by using equipment for refrigerant recovery
and recycling equipment. Discharging refrigerant HFC-
134a (R-134a) into atmosphere would cause adverse
effect to environments.
Action Yes
Go to Step 2.
End.
NOTE
• After recovering refrigerant from system,
the amount of removed compressor oil
must be measured for replenishing
compressor oil.
• When handling recovery and recycling
equipment, be sure to follow the
instruction manual for the equipment.
