The efficient operation and life of the A/C system depends
on the chemical stability of the refrigeration system. Contamination with
dirt, air, or moisture lead to chemical instability, resulting in the following
conditions:
| • | Unstable pressure-temperature relationships |
| • | Premature component wear |
| • | Premature component failure |
Observe the following general practices in order to ensure the chemical
stability of the system:
| • | Before breaking a refrigerant connection, wipe away any dirt or
oil. This will reduce the risk of contamination. Immediately cap, plug, or
tape both sides of the connection. |
| • | Keep all tools clean and dry, including the manifold gage set
and any replacement parts. |
| • | When adding PAG oil, ensure that the transfer device and the container
are clean and dry. |
| • | Set up all necessary tools, cleaners, etc., before opening the
A/C system. Do not leave the A/C system open any longer than is absolutely
necessary. |
| • | Evacuate the A/C system after opening and before recharging. |
| • | All service parts are dehydrated and sealed prior to shipping.
Do not open packaging until the moment of installation. Keep parts at room
temperature before uncapping. This prevents water condensation from the air
entering the system. Reseal any parts as soon as possible. |
