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.

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.

Installation Instructions PXDR10 Drain Kit
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.
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.

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.
