Step 3: Measure and frame out the outside wall plenum opening
IMPORTANT Determine what model of Vert-I-Pak is to be installed. All 9000, 12000 and 18000 btuh units
must follow the dimensions in Figure A. All 24000 btuh units must follow the dimensions in Figure B.
FIGURE A 9000 / 12000 / 18000 BTU/h
The plenum cut out dimensions are 24 5/8" wide
x 30 7/8" high. The bottom of the rough in opening must be 3/4" from the surface the unit will sit
on.
Measure your outside wall as shown in the
illustration. Cut, frame, and square rough
opening. The Wall plenum has a 3/4" break all
the way around to cover the rough cut opening
or required shim.

IMPORTANT THE WALL PLENUM IS NOT DESIGNED TO CARRY STRUCTURAL LOADS. A PROPER
HEADER OPENING MUST BE BUILT INTO THE ROUGH OPENING. THE PLENUM REQUIRES FLASHING,
SHIM AND CAULK FOR A WEATHER-RESISTANT INSTALLATION.
IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO PROPERLY INSTALL THE PLENUM AND MEET
BUILDING CODE REQUIREMENTS.

Step 4: Install Architectural Louver on the Outside Plenum
NOTE The VPAL2 Architectural
Louver is best installed onto the
Outside Plenum (Part A) prior to
Wall Plenum installation. Louver
installation is easier at this point,
and it will help keep the Wall Plenum square during installation.
Step 5: Plenum Installation
Note Proper header and wall penetration must conform to all national and local building codes.

Proper Caulking
Proper Flashing
After the rough cut opening is prepared, you are ready to assemble the two wall plenum parts. Before
caulking and permanent attachment, dry fi t the outside plenum into the rough opening and check for fi t
and level. Caulk (silicone recommended ) the parts well and insert them into the wall as shown.
A) Apply caulk and insert Outside Part A into the hole.
B) Apply caulk and insert Inside Part B into Part A. Be sure that Part A does not back out of the wall hole.

Step 6 - Adjust the Divider
Adjustment
Loosen the two screws located on the top side of the divider.
Slide the top part of the divider toward the outside until the
sealing strip makes contact with the outdoor louver. Tighten
the divider screws to complete the adjustment.
NOTE Let the caulk cure completely before installing
the chassis. This completes the plenum installation.
Condensate Disposal Preparation
for 9000 / 12000 / 18000 Models ONLY
IMPORTANT This step must be performed to ensure that the
chassis installs and seals properly in the wall plenum.
If provisions for condensate disposal are made prior to chassis
installation and the drain is to be located beneath the platform
for the unit, use the accompanying drawing as a guide for cutout locations. Only one drain per unit is required.

Step 7 - Wall Plenum Preparations
FOR 24,000 BTU/h MODELS ONLY:
IMPORTANT This step must be performed to ensure that the chassis installs and seals properly in
the wall plenum.
From the inside of the closet locate the top portion of the factory installed weatherseal gasket, arrow A.
Cut the gasket in the upper left and right hand corners of the plenum. Carefully remove the entire top
piece of gasket (See Figure C).
When completed, the wall plenum installation for the 24000 btuh unit should look like fi gure D.
Figure D is shown with the VPDP1 drain pan installed. The drainpan is required for all 24000 buth
units.

Installation Instructions
DRAIN PAN
For Vert-I-Pak A Series 24,000 Btuh units only.
Please read these instructions completely before attempting installation.
Note: This drain pan must be installed with all VEA24 and VHA24 units.
Models VPDP1
STEP 1: CUT OPENING IN GASKET
Remove an 8" portion of the weather
seal gasket from the bottom left surface of the plenum.
To remove: Cut the gasket in the
lower left corner of the plenum. Then
make a second cut 8" from the left
corner. The gasket should peel away
from the plenum leaving a clean
mounting surface (See detail A).
STEP 2: SEAL AND SET PAN
Prior to placing the drain pan
into the opening run a 1/4" bead
of sealant the entire width of the
removed gasket. The secondary
overfl ow lip must extend into the
plenum to prevent water leaks.
The pan should be mounted
against the 3/4" fl ange of the
plenum, refer to view A.

STEP 3: INSTALL DRAIN PAN
Attach the drain pan to the closet
fl oor with the appropriate fi eld
supplied hardware.
IMPORTANT - To prevent water
leaks use only the factory supplied mounting holes. NEVER
make penetrations in the drain
pan itself.
STEP 4: INSTALL DRAIN PLUG
The drain pan comes with both left
and right-hand drain connections
locations. Determine which of the
two connections will be used to
drain the condensate. Then, with
the factory supplied drain plug,
plug the unused opening.
NOTE - proper sealant must be
applied to the connection to prevent leaks.

STEP 5: INSTALL DRAIN LINE
Condensate line routing options are shown below. Choose the one that best suits your installation.
Never run the condensate line as shown in Option 4 below, as the drain line will come into contact
with the factory-installed isolators beneath the unit.
Option 1
Run condensate line
to right of unit
Option 2
Run condensate line
beneath unit platform
Option 3
Run condensate line
to left of unit
Option 4
Do not run
condensate line
back toward unit
IMPORTANT The drain pan and line must be kept free from debris. Prior to installing the chassis ensure that
there are no blockages in the drain pan or line.
