Louver Installation
pull it back to the wall sleeve rear face so that the louver studs
pass through the holes in the wall sleeve flanges. Securely
tighten the louver in place using the washers and nuts provided.
Install the outdoor louver from inside the room. Hold the louver
with a wire loop or other similar means. Push the louver out
through the rear opening of the room cabinet/wall sleeve and
Heating/Cooling Chassis Installation
Chassis Inspection & Installation Preparation
Check the chassis for damage. Remove and discard the
condenser fan shipping bracket (see Figure 9). Spin the fan
wheels manually to confirm free rotation. Check the refriger-
ant tubing to determine that there are no kinks, and that it
does not rub against other parts. Report any shipping dam-
age to the carrier immediately.
Check the interior of the installed room cabinet/wall box.
Clean out any dirt or debris that may have accumulated,
particularly abrasive materials that could scratch the painted
surfaces.
Optional Condensate Connection
If it has been decided to use the condensate drain, you will
need the optional kit containing one flexible drain connector
tube, one drain tube assembly and two #8 mounting screws.
1. Install the flexible tube on the chassis drain (see Figure 10).
2. Remove the front access cover of the subbase (see Figure
11).
3. Remove the knockout in the bottom left side of the wall
sleeve and mount the drain tube assembly with two
screws (see Figure 11). The assembly may be installed at
various 90 degree positions to fit job requirements.
4. Make the connection to the field supplied drain previously
installed under the subbase installation instructions. The
outlet of the drain tube assembly is
1
⁄
2
" nominal copper
tubing (
5
⁄
8
" O.D. actual). The easiest method of connection
would be with a short length of
5
⁄
8
" I.D. flexible PVC tubing
having a wall thickness of at least
1
⁄
8
" (3mm) to prevent
kinking or collapse, however, follow all local applicable
codes.
Heating/Cooling Chassis Installation
1. Slide the chassis into the room cabinet/wall sleeve until
firmly seated against the weather seals. Caution: Push
only on positions marked “Hand Holds” and/or sheet-
metal flanges. Caution: Do not push on the coil surface,
control box cover, or fan scroll (see Figure 13). Caution:
Make sure that tubing does not catch when inserting
chassis.
2. Plug the electrical cord into the receptacle. Excess cord
should be coiled neatly and stored in the conditioner.
3. If the optional condensate drain kit is used, install the
flexible tube between the chassis and wall sleeve conden-
sate drain by pressing the tube into the drain assembly
(see Figure 12). Caution: When removing the chassis,
remember first to lift the tube from the drain assembly.
4. Set the manual damper operator in open or closed posi-
tion as desired (see Figure 14).
5. Check the “Standby/Normal” switch located on the face
of the control box. For normal heat pump operation,
position the switch to “Normal.” Only the electric heater
will operate when switch is in “Standby’ position.
Residential and institutional cleaning compounds can
cause permanent damage to the packaged terminal unit.
To avoid damage to unit controls and heat transfer sur-
faces, do not spray cleaning compounds onto the dis-
charge grille, the return air opening or the unit controls.
Normal cleaning can be accomplished by wiping the unit
surface with a damp cloth. When using cleaning com-
pounds on carpets, floor or walls, turn the unit off to avoid
drawing potentially damaging vapors into the package
terminal unit.
