536636-UIM-D-1211

When an evaporator coil is installed in an attic or above a finished ceiling, an auxiliary drain pan should be provided under the coil as is specified by most local building codes.

NOTICE

In severe high humidity, high temperature indoor unit environments, an accessory insulation blanket is available to supplement the stan- dard cabinet insulation. Insulate with UPG Kit: 1VJ0117 for B cabi- nets, 1VJ0121 for C cabinets or 1VJ0124 on D cabinets or seal completely with adequate fiberglass insulation using vapor barrier on the outside.

DOWNFLOW AND HORIZONTAL CONVERSION (AV ONLY)

These air handler units are supplied ready to be installed in a upflow and right hand horizontal position. If unit requires left hand positioning, the unit must have the coil assembly repositioned.

1.Remove blower, coil, and filter access panels.

NOTICE

Conversion must be made before brazing the refrigerant connections to the coil.

For downflow and horizontal left installations, follow steps 2 - 8.

2.Remove tubing connection panel.

3.Remove front drain pan, hold down bracket.

4.Slide coil assembly out of air handler.

5.Rotate cabinet 180º so blower outlet is facing down.

6.Re-install coil assembly on downflow bracket.

7.Re-attach front drain pan, hold down bracket.

8.Re-attach tubing connection panel.

9.For horizontal applications, rotate air handler 90º into desired ori- entation.

10.Re-position drain plugs as necessary based on air handler orienta- tion.

11.Re-position and replace access panels.

12.For downflow installations, the cladding should be reconfigured so that the grille and circuit breaker covers having logos and/or black coloring are at the top of the unit on the coil access panel. See below.

13.Apply branding label to air handler in recessed area provided on blower access panel cladding. This label should be applied after the air handler is placed in its proper orientation so the label is right side up.
