Fig. 6—Application with Air Conditioner or Heat Pump Installed with Indoor Unit Above Outdoor Unit
CABINET
Certain maintenance routines and repairs require removal of
cabinet panels. There are 4 basic cabinet designs for air condition-
ers and heat pumps. (See Fig. 8.) The horizontal discharge unit will
be discussed in a separate section of this manual. Note that
separate sections apply according to date of manufacture.
I. REMOVE TOP COVER—BEFORE 1/1/92
NOTE: This section applies to all Reliant products made prior to
January 1, 1992.
1. Turn off all power to outdoor and indoor units.
2. Remove screws holding top cover to coil grille and corner
posts.
3. Remove access panel.
4. Remove information plate.
5. Disconnect fan motor wires, cut wire ties, and remove wire
ties from control box. Refer to unit-wiring label.

III. INFORMATION PLATE—RELIANT PRODUCTS
The information plate is secured to the front of the control box and
provides a cover for it. (See Fig. 9.) This plate also provides a
surface to attach the wiring schematic, superheat-charging tables
with instructions, and warning labels. The plate has 2 tabs on the
top edge that are bent down at slightly more than 90°. When the
information plate is removed, these tabs can be inserted into 2
mating slots in the bottom-front edge of the control box, and the
plate will hang down, forming a lower front panel. (See Fig. 10.)
This is convenient where access to the controls is required while
the unit is operating. The information plate on the small size casing
completely covers the opening below the control box. On larger
models, the information plate may not cover the entire opening. In
this instance, the top cover can be removed and placed on its side
to cover the additional space.
IV. CONTROL-BOX COVER—CUBE PRODUCTS
This panel contains much of the same information as the informa-
tion plate mentioned previously, but is designed only to cover the
control box.
V. REMOVE TOP COVER— AFTER 1/1/92
NOTE: The section applies to all Reliant Products made after
January 1, 1992.
1. Turn off all power to outdoor and indoor units.
2. Remove 5 screws holding top cover to coil grille and coil
tube sheet.
3. Remove 2 screws holding control-box cover.
4. Remove 2 screws holding information plate.
5. Disconnect fan motor wires, cut any wire ties, and move
wires out of control box and through tube clamp on back of
control box.
