Hose/Line HVAC: Technician Safety Information
IMPORTANT
Before attempting any service that requires opening refrigerant lines or components, the person doing the work should be thoroughly familiar with
Handling Refrigerant, Handling Refrigerant Lines and Fittings, and Maintaining Chemical Stability. Very carefully follow the instructions in the
Refrigerant Recovery and Recycling system for the unit being serviced.
See: Refrigerant
Install new ISUZU-approved service replacement air conditioning O-ring seals whenever a joint or fitting is installed, except when the O-ring seals are
provided on new replacement components. Unless service replacement O-ring seals bearing the specified part numbers are used, excessive leakage of
Refrigerant-134a may occur. Refer to the part number for identification.
Air conditioning O-ring seals should be coated with 525 viscosity refrigerant oil just before installation and should be slipped onto the flange tube to
ensure proper locating and sealing. To prevent the possibility of swelling and a reduction in sealing effectiveness, O-ring seals should not be soaked in
refrigerant oil. Before installation, O-ring seals and fittings should be examined to ensure they have not been nicked or deformed. Replace nicked or
deformed parts to prevent refrigerant leakage.
