3. COIL INSTALLATION
WARNING:
Electric furnaces may be connected to
more than one supply circuit.
Upfl ow Furnace —
1. Disconnect all electrical power to the fur-
nace.
2.
If needed, use one of the coil case adapter
kits to match the coil to the furnace air dis-
charge opening. Refer to the Coil Specifi ca-
tions Section for proper kit numbers.
3. Install the coil and level it as needed to
ensure proper condensate drainage. (See
Figure 2)
4.
Seal the enclosure as required to minimize
air leakage.
5.
Connect the refrigerant lines as outlined in
the Refrigerant Lines section.
Downfl ow — These coils may be installed in
downfl ow applications. Installation of the coils
in these applications only require that the furnace
and coil cabinets are securely mounted together
before setting in place.
To Confi gure Horizontal Ready Coils for
Horizontal LEFT Installations:
1) Remove the coil access door.
2) IMPORTANT: Remove the plug from one of
the threaded holes in the horizontal drain
pan. Completely remove the webbing located
in the threaded holes of the horizontal drain
pan. If webbing is not removed, the drain will
not function properly and ceiling damage
may occur.
3) Insert a plug (from the horizontal drain pan)
into the open and unused drain hole in the
drain pan at the bottom of the unit to block
bypass air.
4)
Remove the corresponding drain line knock-
out from the coil access door to allow access
to the horizontal drain.
5) Replace the door.
To Confi gure Horizontal Ready Coils for
Horizontal RIGHT Installations:
1) Remove the coil access door. Unscrew the
line-set tube close-off plate from the front
left cabinet rail.
2) Slide the coil and drain pan assembly out
of the unit.
3) IMPORTANT: Remove the plug from one of
the threaded holes in the horizontal drain pan.
Completely remove the webbing located in the
threaded holes of the drain pan. If webbing
is not removed, the drain will not function
properly and ceiling damage may occur.
4) Remove the sheet metal hairpin covers
(if supplied) from the back of the coil and
discard.
5) Place the horizontal drain pan on the oppo-
site side of the coil. On units with 2 sets of
knockouts, remove the other set of knockouts
in the coil spacing plates and insert support
rod.
6) Insert a plug (from the horizontal drain pan)
into the open and unused drain hole in the
drain pan at the bottom of the unit to block
bypass air.
7) Slide the coil and the horizontal drain pan
assembly back into the unit. Reattach the
tube close off plate.
8)
Remove the corresponding drain line knock-
out from the coil access door to allow access
to the horizontal drain.
9) Replace
the
door.
