VERY IMPORTANT!

YOUR WALL PLENUM WILL WORK ONLY IF INSTALLED CORRECTLY. TAKE NOTICE

TO INSTALL IT IN THE CORRECT ORIENTATION AS SHOWN IN THE ILLUSTRATIONS.

ALWAYS FOLLOW LOCAL AND NATIONAL CODES FOR PROPER INSTALLATION.

Caulk, Attachment screws and Flashing

are fi eld supplied. Silicone caulk is

recommended.

VPAWP1-8 adjusts for walls 5.5 - 8.0" thick.

VPAWP1-14 adjusts for walls 8 - 14.0" thick.

Both installations are similar.

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 open-

ing 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.

FIGURE B 24000 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 1 1/2" 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 3: Measure and frame out the outside wall plenum opening

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 Ple-

num square during installation.

Step 4: Install Architectural Louver on the Outside Plenum

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 5: Plenum Installation

Note Proper header and wall penetration must conform to all national and local building codes.

Step 6 - Adjust the Divider

NOTE Let the caulk cure completely before installing

the chassis. This completes the plenum installation.

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.

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 cut-

out locations. Only one drain per unit is required.

5

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.

Step 7 - Wall Plenum Preparations

IMPORTANT This step must be performed to ensure that the chassis installs and seals properly in

the wall plenum.

For 24,000 BTU/h models only, continue to next page for VPDP1 installation instructions.

Note: This drain pan must be installed with all VEA24 and VHA24 units.

Remove an 8" portion of the weather

seal gasket from the bottom left sur-

face 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 1: CUT OPENING IN GASKET

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.

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 pre-

vent leaks.

STEP 4: INSTALL DRAIN PLUG

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 sup-

plied mounting holes. NEVER

make penetrations in the drain

pan itself.

STEP 3: INSTALL DRAIN PAN

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.

STEP 5: INSTALL DRAIN LINE

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.

Option 1

Run condensate line

to right of unit

Option 3

Run condensate line

to left of unit

Option 2

Run condensate line

beneath unit platform

Option 4

Do not run

condensate line

back toward unit
