PTACInstallation Recommendations
ForproperPTACunit performance and maximum operating life please refer to the minimum installation clearances below:
FigureI
PTAC units should be installed
no closer than 12" apart when
two units are side by side. If
three or more PTAC units are to
operate next to one another allow
a minimum of 36" between units.
Also, a vertical clearance of 60"
should be maintained between
units installed.

Figure2
For PTACson the ground floor or anytime obstructions are present, use the following guidelines:
For minor obstructions
such as lamp poles
or small shrubbery a
clearance of 12" from the
outdoor louver should be
maintained.
For major obstructions
such as a solid fence, wall
or other heat rejecting
device like a condensing
unit, a minimum distance
of 36" should be kept.

Installation Instructions PXDRIODrainKit
NOTE: Determine whether drain will be located within the wall, on the indoor side, or will drain to the exterior of the building. Follow
appropriate instructions below depending on your particular type of installation.
Internal Drain (optional for new construction)
NOTE: If installing an internaldrain, you MUST install a drain kit
on the wall sleeve beforethe wall sleeve is installed.
,
,
,
5,
,
,
Refer to Figure 3 below and locate the drain within the
"Primary" area for best drainage. Maintain at least a 1!2"
clearance from the embossed area.
Using the mounting platewith the 1/2" hole asa template,
mark and drill two, 3/16" mounting holes and a 1/2" drain
hole.
Remove the backing from the gasket and mount iton the
flat side of the mounting plate. (See Figure 4.) Insert the
drain tube through the hole in the gasket and mounting
plate so the tube flange will be against the wall sleeve.
Position the assembly beneath the drilled holes and
secure it with #10-24 x 1/2" machine screws and lock
nuts provided. Seal the tops of the screws with silicone
caulking.
Use 1/2"I.D.coppertube, PVCpipe,orvinyl hose(obtained
locally)toconnectthe internaldraintubetothedrainsystem
in the building.
Referring to Detail A on page 6, locate and assemble the
(2) two cover plates and gaskets over the drain holes at
the rear ofthe wall sleeve.Attach them with the#10 sheet
metalscrews provided. Make certain thatthe four overflow
slots at the rear of the wall sleeve are not blocked (See
drawing of the back of the sleeve on page 6).
If a deep wall extension (PXWE) is used, after installing
the field supplied flashing, caulk as required. Be sure to
caulk around the flashing and the wall sleeve where the
hole was drilled for the drain tube.

ExtemalDrain(for newconstructionorunitreplacement)
When using an external drain system, the condensate is removed through either of two drain holes on the back of the wall sleeve.
Select the drain hole which best meets your drainage situation and install the drain kit. Seal off the other with a cover plate.
Drain Tube Installation
1. Peel the backing tape off the gaskets and apply the
sticky side to one cover plate and one mounting plate
as shown in DetailsA and B.
2. Placethedraintubethroughthegasketandthemounting
plate with theflange toward the wall sleeve.
Attach the drain tube assembly to one of the two drain
holes at the rear of the wall sleeve. The large flange
on the mounting plateis positioned atthe bottom ofthe
sleeve facing toward the sleeve, Detail B. When the
drain tube ispositioned atthe desired angle,tighten the
screws.
NOTE: If the wall sleeve has not been installed, the drain tube
must be rotated to a horizontal position until after the
sleeve is installed. Tighten the mounting plate screws
when the tube is in the proper position. Make certain
that thefour overflow slots atthe rear ofthe wall sleeve
are not blocked. (See the drawing below.)
Cover Plate Installation
4. Mount the foam gasket to the cover plate. Using two
#10 x 1!2" sheet metal screws (provided), attach the
cover plate to the remaining drain hole. Make certain
the largeflange on the plate is positioned at the bottom
of the sleeve.
5. Discard the additional cover plate, gasket, machine
screws, and Iocknuts.

NOTES:
The large flange on the mounting plate is positioned atthe bottom of the sleeve facing toward the sleeve. The drain tube must be rotated to a horizontal
position to allow for the wall sleeve to be installed into the wall. Once the wall sleeve is installed, return the drain tube to a downward angle.

NOTE: Insurethatthe unitisonlyinstalledin awallstructurallyadequatetosupport the unitincludingthesleeve,chassisand accessories.
If the sleeve projects more than 8" into the room, a subbase or other means of support MUST be used. Please read these instructions
completely before attempting installation.

Note: All 230/208V units are manufactured with a 60" power cord. The receptacle
locations above must be followed to ensure proper connections.
ForDeep Wall Installation See Section II
The following instructions apply ONLY to walls less than
13 1/4" in depth.
1. From inside the building, position the wall sleeve in the
opening and push itthrough the wall so it protrudes at least
1/4"on the outside, note Figure 5.
,Position the wall sleeve with a slight tilttowards the outside
tofacilitate condensate drainage. Itshould be levelside-to-
sideandthefront should be 1!4bubble higherthan theback.
DO NOT allow any pitch toward the inside.
Electrical shock hazard.
Turn electric power OFF at the fuse box or service panel
before making any electrical connections and ensure a
proper ground connection is made before connecting line
voltage. Failure to do so can result in property damage,
personal injury and/or death.

,
Drill two 3/16" holes through each side of the sleeve
approximately 4" from top and 4" from bottom of sleeve.
Screw four #10 x 1" screws (included) or appropriate
fasteners for your installation, through the holes in thesides
of the wall sleeve.
Apply sealant around the wall sleeve where it projects
through the inside and outside wall surfaces. Apply the
sealant to thescrew heads or the tops of thefasteners used
in Step #3.
NOTE: When sealing the sleeve on the outside of the
building, be careful NOT to let the sealant block the two
condensate drain holes or the four overflow slots at the
bottom flange of the sleeve.
Ifthechassis and exterior grilleare to be installed later,leave
the weatherboard and center support in place, otherwise
remove and dispose of them.
Provide a support lintel if the wall sleeve is installed in a
concrete or masonry wall. (See Figure 7.)
