PTACInstallation Recommendations

Forproper PTACunit performance and maximumoperating 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.

Installation Instructions PXDRIODrainKit

NOTE: Determine whether drain will be located within the wall, on the indoor side, orwill 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.

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.

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 certainthatthe four overflow slots at the rear of the wall sleeve are not blocked (See drawing of the back of the sleeve onpage 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(fornewconstructionor unit replacement)

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. Placethe draintubethroughthegasket andthemounting plate with theflange toward the wall sleeve.

Attach the draintube 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 at the rear ofthe wall sleeve are not blocked. (See the drawing below.)

Figure4 DrainKit Installation

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 at the 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.

ForDeep Wall Installation See Section II

The following instructions apply ONLY to walls less than

13 1/4" indepth.

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 tilt towards the outside tofacilitate condensate drainage. Itshould be levelside-to- sideand thefront 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.
