sure do not have access panels.

restore power until work is completed.
2. Remove access panel if applicable.
• The 38APS,APD025-030, and 30RAP011-030 units
have one compressor access panel with one latch at
the top of the panel. See Fig. 1.
• The 38APD040-060 and 30RAP035-060 units have 2
compressor access panels with one latch at the top of
each panel. See Fig. 2.

panel with 2 latches at the top of the panel. See Fig. 3.

sides of the panel.
