ForproperPTACunitperformanceandmaximumoperatinglifepleaserefertothe minimuminstallationclearancesbelow:
Figure I
PTAC units should be installed
no closer than 12" apart when
two units are side by side. If
three of 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.

Installation Instructions PXDRIODrain Kit
NOTE: Determine whetherdrain willbe located within the wall, on the indoor side, or will drain to the exteriorof the building. Follow
appropriate instructionsbelow depending on yourparticular type of installation.
Internal Drain (optional for new construction)
NOTE: Ifinstalling an internaldrain,you MUST install a drain kit on
the wall sleeve before the wall sleeveis installed.
1, 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.
2. Using the mounting plate with the 1/2" hole as a template,
mark and drill two, 3/16" mounting holes and a 1/2" drain
hole.
,Removethe backingfrom thegasket 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.
4. Position the assembly beneaththe drilled holes and secure
itwith #10-24 x 1/2" machine screws and lock nuts provided.
Seal the tops of the screws with silicone caulking.
5. Use 1/2" I.D.copper tube, PVCpipe, orvinyl hose (obtained
locally) toconnect the internaldrain tube tothe drain system
in the building.
6. Referring to Detail A on page 6, locate and assemble the
(2) two cover plates and gaskets over the drain holes atthe
rear ofthe wall sleeve.Attach them with the #10 sheet metal
screws provided. Makecertain that thefour overflow slotsat
the rear of the wall sleeve are not blocked (See drawing of
the back ofthe sleeve on page 6).
7. 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 thewall sleeve where the hole was
drilled for the drain tube.

ExtemalDrain(for newconstructionorunit replacement)
When usingan external drain system, the condensate is removed through eitherof two drain holes on the back of thewall sleeve. Select
the drain hole which best meets your drainage situation and install the drain kit. Sealoff the other with a cover plate.
Drain Tube Installation
1. Peelthe backing tape off thegaskets and apply thesticky
side toone cover plateand one mounting plateas shown
in DetailsA and B,
2. Placethedrain tube throughthe gasketand the mounting
plate with the flange toward the wall sleeve.
3. Attach the drain tube assembly to one of the two drain
holes at the rear of the wall sleeve. The large flange on
themounting plateispositionedatthe bottomofthesleeve
facing toward thesleeve, Detail B. When thedrain tube is
positioned at the desired angle,tighten the screws.
NOTE: Ifthewallsleeve hasnot been installed,the draintube 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 the four
overflow slotsatthe rearofthewallsleeveare notblocked.
(See the drawing below.)
Cover Plate Installation
4. Mountthefoamgaskettothecoverplate. Usingtwo#10x
1/2"sheet metal screws (provided), attachthe cover plate
tothe remaining drainhole. Make certain the largeflange
on the plate ispositioned at the bottom of the sleeve.
5. Discardtheadditionalcoverplate,gasket,machinescrews,
and Iocknuts.

outside, note Figure 5.
2. Position thewall sleeve with a slight tilt towards the outside to
facilitate condensate drainage. It should be levelside-to-side
and the front should be 1/4 bubble higher than the back. DO
NOT allow any pitch toward the inside.

Section II - DeepWall Installation(PXWE)
If the wail is thicker than allowed in the notes in Figure 6, a sheet
metal wall sleeve extension and flashing MUST be used.
Installation Instructions for the PXWE - 4" Wall Sleeve
Extension
The following points MUST be considered when installing a wall
sleeve extension:
Provision must be made to direct excess condensate from
the back of the wall sleeve into the extension then outside
the building or to a drainage system.
2. Air baffles mustbe mounted to properlydirect airflow to and
from the condenser.
3. The wail sleeve extension design must allow for the proper
mounting of the grille.
4. Caulking isrequired atansiteswhere condensate or external
water could potentially infiltrate intothe building.
6. Condensate notches and overflow slots must be kept clear
ofsealant and gaskets so condensate canflow freely intothe
wall sleeve extension.
NOTE: Improperfabricationor installationofa wallsleeveextension
will impair PTAC performance.
Extension Installation
Secure thewall sleeveextensionto thewailsleeve beforeinstalling
it in the wall. Refer to Figure 8 for a guide for fabrication of a
condensate drip panel. The panel MUST extend the full depth of
the wail sleeve and the wail sleeve extension.
Payparticular carein sealingand caulkingthe panelwhere itmakes
contact with the wall sleeve (see Figure 8).After installationin the
wall, secure with fasteners through the sides. Use a good grade
of silicone sealant around the sleeve extension. Seal all exposed
screw heads. When the installation is complete, the outside grille
should be attached to the wall sleeve extension.
5. Fabricate and install metal flashing in wall to serve as a drip
panel. Refer to drawingfor more information.
Figure8

®IMPORTANT NOTE: The silicone bead MUST extend 3"
up the side of the two flanges to prevent condensate
from leaking.

Installation InstructionsModelPXGAStandardGrille
1. Remove the center support and weatherboardifstininstalled
in the sleeve.
2. Insert six plastic grommets into the grille openings from the
outside of the grille as shown in Figure 9.
3. Insert two #8 x 3/8" sheet metal screws (provided) in the top
two outside edge plasticgrommets, and tighten them halfway
intothe grommets.
4. CAUTION: Bodilyinjury can be caused by grillesfalling from
a building during installation. It is recommended that a safety
line be attached to the grille and an anchor point inside the
building durinq installation.
5. Graspthegrille bytheattached plastichandles. Positionitwith
thecondensate drain knockoutsfacing down. From insidethe
building, maneuver the grille through the wall sleeve and pull
toward you untilthe screw headsare inserted intothe keyhole
slots at the top of the wall sleeve. Tighten the two screws
completely.
6. Insert the remaining screws into the remaining holes and
tighten securely.
