PTAC Installation Recommendations

For proper PTAC unit performance and maximum operating life please refer to the minimum installation clearances below:

Figure 1

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.

Figure 2

For PTACs on the ground oor 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.

The above suggestions are for reference only and do not represent all possible installations. Please contact the factory for information regarding affects of other installation arrangements. By following these simple recommendations you can be condent that your Friedrich PTAC will provide years of worry free operation.

Installation Instructions PXDR10 Drain Kit

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 internal drain, you MUST install a drain kit on

the wall sleeve before the wall sleeve is 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.

3. Remove the backing from the gasket and mount it on the at side of the mounting plate. (See Figure 4.) Insert the drain tube through the hole in the gasket and mounting plate so the tube ange will be against the wall sleeve.

4. 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.

Figure 3

Drain Kit Location and Installation

5. Use 1/2" I.D. copper tube, PVC pipe, or vinyl hose (obtained locally) to connect the internal drain tube to the 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 at the rear of the wall sleeve. Attach them with the #10 sheet metal screws provided. Make certain that the four overow slots at the rear of the wall sleeve are not blocked (See drawing of the back of the sleeve on page 6).

7. If a deep wall extension (PXWE) is used, after installing the eld supplied ashing, caulk as required. Be sure to caulk around the ashing and the wall sleeve where the hole was drilled for the drain tube.

External Drain (for new construction or 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 Details A and B.

2. Place the drain tube through the gasket and the mounting

plate with the ange 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 ange on the mounting plate is positioned at the bottom of the sleeve facing toward the sleeve, Detail B. When the drain tube is positioned at the 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 the four overow slots at the rear of the wall sleeve are not blocked. (See the drawing below.)

Drain Kit 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 large ange on the plate is positioned at the bottom of the sleeve.

5. Discard the additional cover plate, gasket, machine screws, and locknuts.

NOTES: The large ange 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.

Wall Sleeve Installation Instructions (PXWS)

NOTE: Insure that the unit is only installed in a wall structurally adequate to support the unit including the sleeve, chassis and 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.

Figure 5

Typical Wall Sleeve Installation

For Deep 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 it through the wall so it protrudes at least 1/4" on the outside, note Figure 5.

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

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.

3. 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 the sides of the wall sleeve.

4. Apply sealant around the wall sleeve where it projects through the inside and outside wall surfaces. Apply the sealant to the screw heads or the tops of the fasteners 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 overow slots at the bottom ange of the sleeve.

Lintel Installation

5. If the chassis and exterior grille are to be installed later, leave the weatherboard and center support in place, otherwise remove and dispose of them.

6. Provide a support lintel if the wall sleeve is installed in a concrete or masonry wall. (See Figure 7.)
