INSTALLATION
To install, follow the removal steps in the reverse order,
noting the following points:
1. To install a new evaporator assembly, add 50cc
(1.4 Imp fl oz) of new compressor oil to a new core.
2. Tighten the refrigerant outlet line to the specified
torque.

3. Tighten the refrigerant inlet line to the specified
torque.
Inlet Line Torque Nám (kgám / lbáft)
15 (1.5 / 11)
4. O-rings cannot be reused. Always replace with new
ones.
5. Be sure to apply new compressor oil to the O-rings
when connecting lines.
