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,

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.

®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.
