Installation Procedure

Important:  If replacing the condenser, add the refrigerant oil to the condenser. Refer to Figure for system capacity information.

1. Replace the condenser insulators (2), if necessary:
   1. Remove all traces of the old insulators.
   2. Using isopropyl alcohol, or equivalent, wipe clean the front surface of the condenser LH and RH edges.
   3. Remove the paper backing (1) from the new insulators (2).
   4. Align and install the insulators (2) while keeping a gap (3) of 1 mm (0.039 in) between the insulators (2) and the inner edges of the condenser, as shown.
