Anchoring The Wall Sleeve
Anchoring the wall sleeve is accomplished as shown in
Fig

ure 14
. Use the rubber isolation washers with the fasteners
to minimize sound transmission from the equipment to the
wall, at the point of contact. A 5⁄16" (8mm) hole is provided
on each side, 2" (51mm) down from the top and 2" (51mm)
in from the rear of the wall sleeve. It may be necessary to
drill additional holes in the wall sleeve to firmly secure it.
CAUTION
Do not drill holes in the base of the wall sleeve. Use shims
between the wall and the wall sleeve to prevent wall sleeve
distortion during anchoring.

Installing Louvers
1. Remove louver from its shipping carton and also the
hardware package for mounting the louver.
2. Remove outside weather plug and weather panel from
wall sleeve.
3. Make a temporary handle by looping a piece of flexible
wire or heavy cord through the louver. This enables
the installer to keep a firm grasp on the louver when
installing from inside the room.
4. Push the louver through the opening at the rear of the
wall box, then pull the louver back to the wall sleeve
flange so that the louver studs pass through the holes in
the flange.
5. Attach washers and nuts and secure louver in place.
6. If the cooling chassis is not to be immediately installed,
replace the weather panel.
IMPORTANT
Air flow required for PTAC units must not be restricted by ex
-
terior plants or walls. Plants or shrubs must not be planted in
close proximity to the outside grille of the PTAC unit. Vegeta
-
tion planted too close to grilles will cause discharge air to be
recirculated, thereby increasing electrical consumption. War
-
ranty will be voided if it is determined that the compressor life
is shortened from overheating due to close proximity of outside
obstructions.
Note:
Discharge air restrictions include, but are not limited to:
• Vegetation
• Concrete walls or barriers
• Overhangs that do not allow discharge air to rise
• Installation of bug screen of any kind
• Outdoor louvers by others unless approved by the factory
WARNING
Improper electrical supply can cause property damage, severe
personal injury or death.
Electrical Service
All wiring should be in accordance with all local and Na
-
tional Electrical Code requirements.
Units are supplied with an attachment cord and plug which
exit from the bottom of the conditioner on the control side.
The cord for 115V, 208V and 230V has a usable length of
66" (1676mm) from where it exits the conditioner. The use
of extension cords to increase the length of the plug/cord set
is not recommended.
The attachment plug size should be used to determine the
circuit ampacity and overcurrent protection. Time delay,
overcurrent protection devices are recommended to prevent
unit damage and to avoid nuisance tripping.
Outlets are generally located beneath the conditioner, on
or recessed in the wall so it is concealed by the conditioner
overhang and kickplate.
Installing Cooling Chassis
Correct installation of the cooling chassis is extremely im
-
portant to insure the proper operation of the unit. Install the
chassis as follows:
1. Remove outer carton and inspect for any shipping
damage. Report any found to the carrier.
2. Check nameplate data on chassis to insure that the
correct job site distribution has been made with respect
to cooling capacities. Generally, corner rooms require
larger capacities.
3. Remove chassis from carton by pulling evenly on
substantial portion of unit.
