DOWNFLOW INSTRUCTIONS

Important: Read instructions below carefully

1.Before putting the Air Handler in the downflow

position, remove the three access panels and

remove the metal coil retaining bracket and filter

close off. Then remove the horizontal and vertical

drain pans. The horizontal pan is not required for

downfolw application

2.After removing the coil, turn the Air Handler to

the downflow position and relocate the (8) brackets

which include (1) tie bracket (1) rear channel

bracket, (2) zee coil supports, (2) stiffener brackets,

and (2) 3" 2 flat insulation retaining brackets. In

effect, brackets, coil, and 2 lower access panels

will be assembled 180 degrees from their former

position and shifted down with return in up position

as shown in fig.1 and fig.2.

3. Assemble drain pan insulation kit to the

bottom of the drain pan to prevent drain pan

from sweating during operation.

4. Place 3" flat insulation retainer on the bottom of

each coil slab against the aluminum fins as shown

in Fig.3. This will reduce the potential for water

blow-off into the air stream.

5. Slide the coil assembly into Air Handler and

reattach the metal coil retainer bracket to tie

bracket. See Fig.2. Then reattach the upper access

panel followed by the two lower access panels

to match the tubing and drains.

6. A 4" to 3" removable panel is recommended at

the point where the duct meets with the return

part of the Air Handler unit to allow easier

removal of coils that are too tall.

7. The "AD" coils are shipped with a check flowrator

for use with either cooling or heat pump outdoor

section which is accessible from the outside of

the unit.

WARNING: The "A" coil contains 150

p.s.i.g. of air pressure

Before setting up flowrator assembly for field

brazing see page 12 or read the Warning label

on the lower access panel.
