COIL INSTALLATION
On all installations without a coil, a removable access panel is recom-
mended in the outlet duct such that smoke or reflected light would be
observable inside the casing to indicate the presence of leaks in the
heat exchanger. This access cover shall be attached in such a man-
ner as to prevent leaks.

FURNACE ASSEMBLY - MC & FC SERIES COILS
These coils are factory shipped for installation in either upflow or down-
flow applications with no conversion.
Position the coil casing over or under the furnace opening as shown in
Figure 2 after configuring coil flanges as required see "Coil Flange" sec-
tion below.
COIL FLANGE INSTALLATION
The coils include removable flanges to allow proper fit up with furnaces
having various inlet and outlet flange configurations. The two flanges
are attached to the top of the coil in the factory during production. For
proper configuration of flanges refer to Figure 3.

FURNACE ASSEMBLY - MC SERIES COILS ONLY
MC coils are supplied ready to be installed in a horizontal position. A
horizontal pan is factory installed. MC coils should be installed in all hor-
izontal applications with the horizontal drain pan side down.

FIGURE 4: Horizontal Right Application
For horizontal left hand applications no conversion is required to an MC
coil when used with a downflow/horizontal furnace. A mounting plate,
supplied with every coil should always be installed on the side desig-
nated as top side. See Figures 4 & 5.

FURNACE ASSEMBLY - PC SERIES COILS
These upflow coils are designed for installation on top of upflow fur-
naces only.
If the coil is used with a furnace of a different size, use a 45° transition
to allow proper air distribution through the coil.
1. Position the coil casing over the furnace opening as shown in Fig-
ure 6.
2. Place the ductwork over the coil casing flange and secure.
3. Check for air leakage between the furnace and coil casing and seal
appropriately.
Do not drill any holes or drive any screws into the front duct flange on
the coil in order to prevent damaging coil tubing. See Figure 6.
