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.

6.Lift top cover from unit.

7.Reverse sequence for reassembly.

II. REMOVE FAN-MOTOR ASSEMBLY—BEFORE 1/1/92

NOTE: This section applies to all Reliant products made prior to January 1, 1992.

1.Perform items 1 through 6 above.

2.Remove nuts holding fan-motor top cover.

3.Remove motor and fan blade assembly.

4.Reverse sequence for reassembly.

5.Prior to applying power, check that fan rotates freely.

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.
