PTACInstallation Recommendations
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.
