6.	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.
7.	Proper electrical supply must be available.
8.	Clearances must also be taken into consideration, and provided
	for as follows:
	A. Refrigerant piping and connections are located in the front.

If electric heat is used, a minimum clearance of 1” must be main- tained on all sides of the supply air duct and/or plenum continuously for up to 3’ (See Figure 1).

B.	Maintenance and servicing through the front or access side
	of unit with both sides and rear of unit having zero inch clear-
	ance.
C.	Condensate drain lines are connected in the front (clear of fil-
	ter).
D.	Filter removal.
E.	When no electric heat is used, the unit as well as all duct
	work and plenum are designed for zero clearance to combus-
	tible materials.

HORIZONTAL DRAIN PAN CONVERSION

These air handler units are supplied ready to be installed in a right hand horizontal position. If unit requires left hand positioning, the unit must have the pan installed in the correct position.

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

NOTE: Conversion must be made before brazing the refrigerant con- nections to the coil.

2.See Figure 3, remove two screws from horizontal drain pan, to remove pan from position “3A” if factory installed.

3.Position horizontal pan, as required in either “A” or “B” position, locking it into the vertical drain pan as shown.

4.Horizontal drain pans have 4 plugged drains. Remove plugs from connections being used.

NOTE: If this step is overlooked, it can lead to a water problem later.

5.Use removed plug to plug primary of upflow drain pan.

6.Attach horizontal pan with 2 screws removed in step no. 2 or sup- plied with the unit. Ensure that the drain pan is lying flat against the insulation of the cabinet.

7.Horizontal drain cutout in the center access panel should be removed by using a utility knife (if not previously cut out).

8.Re-position and replace access panels.

DO NOT TRY TO KNOCK OUT PANEL OPENING FOR SECOND- ARY DRAIN PAN. SEE ITEM 7.

Models F*FP045,048,060 have a coil baffle and support bracket factory installed for right hand horizontal application (refer to Figure 3C). For left hand applications the coil support bracket must be moved to the right side of the coil, and the coil baffle must be rotated to avoid water blow-off.

To rotate baffle, remove the coil assembly from the unit (remove front two screws holding the coil support bracket and the two screws holding the drain pan). Remove four screws in coil baffle and remove the coil baffle and rotate ends.

Resecure the baffle and reinstall the coil assembly ensuring that the rear of the drain pan is secured under the back flange of the unit. Reinstall the coil support bracket on the right side of the coil.
