Lanos S Sedan L4-1.6L DOHC D-TEC MFI (2001)
Refrigerant: Description and Operation
The efficient operation and life of the air conditioning system is dependent upon the chemical stability of the refrigeration system. When foreign
materials, such as dirt, air, or moisture, contaminate the refrigeration system, they will change the stability of the refrigerant and the polyalkaline glycol
(PAG) compressor oil. They will also affect the pressure-temperature relationship, reduce efficient operation, and possibly cause interior corrosion and
abnormal wear of moving parts.
Observe the following practices to ensure chemical stability in the system:
-
Wipe away dirt or oil at and near any connection before opening that connection. This will reduce the chance of dirt entering the system.
-
Cap, plug, or tape both sides of a connection as soon as possible after opening the connection. This will prevent the entry of dirt, foreign material,
and moisture.
-
Keep all tools clean and dry, including the manifold gauge set and all replacement parts.
-
Use a clean and dry transfer device and container to add PAG refrigerant oil. This will ensure that the oil remains as moisture-free as possible.
Refer to "Discharging, Adding Oil, Evacuating, and Charging Procedures for A/C System".
-
Have everything you need ready to allow you to perform all operations quickly when opening an A/C system. Do not leave the A/C system open
any longer than necessary.
-
Evacuate and recharge any A/C system that has been opened. Refer to "Discharging, Adding Oil, Evacuating, and Charging Procedures for A/C
System" for the instructions to perform this procedure properly.
All service parts are dehydrated and sealed before shipping. They should remain sealed until just before making connections. All the parts should be at
room temperature before uncapping. This prevents condensation of moisture from the air from entering the system. If the caps have been removed, but
the connections cannot be made promptly, reseal all parts as soon as possible.
