Handling of Refrigerant Lines and
Fittings
1. Using too low or too high a torque when tightening a
fitting can result in loose joints or deformed joint parts.
2. Back up the opposing fitting to prevent the distortion of
the connecting lines or the components. Back up both
the swaged fitting on the flexible hose connections and
the coupling to which it is attached two wrenches to
prevent turning the fitting and damaging the ground seat.
Maintaining Chemical Stability In
the Refrigeration System
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, con-
taminate the refrigeration system, they will change the stabil-
ity of the refrigeration and the polyalkalene glycol (PAG) com-
pressor oil. They will also affect the pressure-temperature
relationship, reduce efficient operation and can possibly cause
interior corrosion and abnormal wear of moving parts.
Observe the following practices to ensure chemical stability
in the system:
1. Wipe away dirt or oil at and near any connection before
opening that connection. This will reduce the chance of
dirt entering the system.
2. 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.
3. Keep all tools clean and dry including the manifold gauge
set and all replacement parts.
4. 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.
5. When opening an A/C system, have everything needed
to perform all operations ready. Do not leave the A/C
system open any longer than necessary.
6. Evacuate and recharge any A/C system that has been
opened.
