NOTE: The weight distribution and center of gravity information include the impact of an economizer, the largest indoor fan motor, and a VFD (variable frequency drive). On units with a return fan or high-capacity power exhaust, the largest motors and VFD are also included. These weights do not include the impact of other factory-installed options such as barometric relief, power exhaust, high-capacity indoor coil, hot water coil, or indoor fan.

Locate the four 11/4-in. drain coupling assemblies and mounting screws (shipped in a bag taped to the basepan in the supply fan section, located behind the access panel marked FAN SECTION). The drain couplings are a 10-gage plate with a 11/4 in. half coupling welded to the plate.

After final positioning of the unit, perform the following procedure:

1.At each of the four secondary drain locations (marked with labels on the unit base rail), position the drain cou- pling assembly in the side of the base rail. Mark the screw holes and the drain hole locations on the base rail.

2.Drill holes for drain outlet (use 13/8-in. hole saw) and for the mounting screws (use 3/16-in. drill bit).

3.Install a drain coupling assembly using screws provided at each secondary drain hole location.

4.Using field-supplied fittings and pipe sections, assemble U-traps at each secondary drain fitting. See Fig. 24. Pro- vide minimum size of ½-in. pipe for secondary drains. Use a trap at least 4-in. deep for size 030-070 units and 7-in. deep for size 075-100 units.

5.Apply a bead of RTV or similar sealant around the drain assemblies.

Consult local plumbing codes for direction on joining multi- ple drain lines. Total size of any combined line does not need to exceed nominal 2-in. size of primary drain connection.

Fill the U-traps at the secondary drain locations prior to unit start-up. Also check the U-traps before each cooling season to ensure the traps are filled and functioning properly.
