SERVICE
Service Access —
All unit components can be reached
through clearly labeled hinged access doors. These doors are
equipped with tiebacks, but if heavy duty servicing is needed,
it is recommended that the doors be removed or propped open.
Each door is held closed with 3 latches. The latches are
secured to the unit with a single

-in. Ϫ20 x
1

-in. long
bolt. See Fig. 50.
To open, loosen the latch bolt using a 7/16-in. wrench.
Pivot the latch so it is not in contact with the door. Open the
door. To shut, reverse the above procedure.
NOTE: Disassembly of the top cover may be required under
special service circumstances. It is very important that the
orientation and position of the top cover be marked on the
unit prior to disassembly. This will allow proper replace-
ment of the top cover onto the unit and prevent rainwater
from leaking into the unit.
IMPORTANT:After servicing is completed, make sure
door is closed and relatched properly, and thatthe latches
are tight. Failure to do this can result in water leakage
into the indoor-air section of the unit.
