secondary drain offers protection from overflow. The secondary
drain feature is piped into the base of the unit and drains through
the weep holes outside. Reconnect 3” piece of clear flexible tubing
to secondary drain on drain pan. Position secondary drain through
grommet of chassis and connect to flexible tubing (prime trap
prior to operating).
Local codes should be followed to route the furnace condensate
to the proper drainage. The furnace condensate drain kit provides
materials for two different drain locations described later in this
manual (page 9-10). Ensure that the condensate is able to freely
drain through the lines with minimal condensate buildup to prevent
line freezing during low ambient conditions
The grille side must be kept free of any obstructions that will
reduce or alter the air flow pattern. The unit must be installed
at least 4 feet (1.22 m) from electric meters, gas meters,
regulators, and relief equipment. The vent of the unit is located
at the front grille. Distances from adjacent public walkways,
adjacent buildings, openable windows, and building openings
must be consistent with the National Fuel Gas Code ANSI Z223.1
and/or CAN/CGA-B149 installation codes, as well as local codes.
If an optional architectural grille is to be used on standard units,
the stamped grille provided must be removed. Consult the factory
prior to ordering product(s) that require an optional architectural
grille.

!CAUTION
To remove the chassis from the cabinet:
Turn off power to the unit. Remove the two lower access panels from the
cabinet. Disconnect the drain line from the evaporator coil drain connection.
Disconnect the secondary drain flexible tubing & trap to avoid damage
(prime trap when reinstalling). Depress and hold the release latch on the
chassis power wiring connector and unplug it from the cabinet power wiring
connector. Depress and hold the release latch on the control wiring connector
and unplug it from the cabinet control wiring connector.
Unfasten the screws attaching the chassis to the unit located above the
control deck. Temporarily secure the chassis power and control wiring and
connectors to the top of the indoor coil cover to prevent damage during
chassis removal.
Carefully slide the chassis out of the cabinet by grasping the handles located
beneath the evaporator coil drain pan and pulling toward you while keeping
the chassis centered in the cabinet. As the chassis is removed, keep the
chassis level until the outdoor fan cover passes the cabinet seals. Damage to
the cabinet seals will result if the chassis is not kept level until the outdoor
fan cover has passed the cabinet seals. After the chassis is removed, it
should be handled using the chassis base and evaporator drain pan, not by
using refrigerant piping or the outdoor fan mount. The bottom of the chassis
is not smooth and will damage floors if slid.
To install the chassis into the cabinet:
Turn off power to the unit. Temporarily secure the chassis power and control
wiring and turn Off power to the unit. Temporarily secure the chassis power
and control wiring and connectors to the top of the indoor coil cover to
prevent damage during chassis installation. Place the outdoor coil section
of the chassis onto the cabinet rails. Lift the rear of the chassis using the
handles located beneath the evaporator coil drain pan so that the chassis
is level and centered as it is pushed in the cabinet. Damage to the cabinet
seals will result if the chassis is not kept level until the outdoor fan cover
has passed the cabinet seals, and if the chassis is not kept centered in the
cabinet. After the chassis is all the way in the cabinet, check that the chassis
Is centered in the cabinet by verifying that it is in contact with the cabinet
seals on both sides.
Fasten the screws above the control deck to secure the chassis to the cabinet.
Install the chassis power wire connector and the control wiring connector
into their respective cabinet wiring connectors so that the connectors latch.
Connect the drain line to the evaporator coil drain connection. Reconnect
3” piece of clear flexible tubing to secondary drain on drain pan. Position
secondary drain through grommet of chassis and connect to flexible tubing
(prime trap prior to operating). Install the lower access panels on the cabinet.
Turn on power to the unit.
ALL phases of this installation must comply with NATIONAL,
STATE AND LOCAL CODES. The manufacturer assumes no
responsibility for equipment installed in violation of any code
requirements.
Be sure that the electrical data specied on the unit rating plate
corresponds to what is available at the installation site and NEC
for installation requirements.
This unit MUST be installed in an outside wall for thru-the-wall
installation ONLY.
Be sure that the electrical service provided to the building can
handle the load imposed by the unit.
