AIRESHARETM ROOM-TO-ROOM VENTILATOR
MODEL AS1
©2008 TJERNLUND PRODUCTS, INC. ALL RIGHTS RESERVED P/N: 8504136 Rev A 02/08
DESCRIPTION
The Tjernlund AireShare™ Room-to-Room Ventilators distribute air from one conditioned space to another. Virtually every home has a
room that is uncomfortably hot or cold from which some of that room’s air can be shared with an adjacent room, making the temperature
of both rooms more comfortable. The AireShare™ transfers air through the wall cavity created between two wall studs. The AireShare’s
unique option of moving the air up or down within the wall cavity allows for optimum heat transfer between rooms – a typical application
will affect the temperature 3° F per hour. In addition, locating the Grille and Diffuser, one high the other low, prevents the transfer of light
and sound between these adjacent rooms.
SPECIFICATIONS & COMPONENTS
GENERAL INFORMATION
Every Tjernlund AireShare™ Room-to-Room Ventilator is electrically factory line tested before shipment.
After opening carton, inspect thoroughly for shipping damage. Impeller should rotate freely and all electrical wires and connections
should be secured. If any damage is found, notify freight carrier and your distributor immediately and file a concealed damage claim.
INSTALLATION RESTRICTIONS
The AireShare™ Ventilator must be installed by a qualified installer in accordance with these instructions and all local codes or in their
absence in accordance with the latest editions of the International Residential Code and International Electrical Code. Improper installa-
tion can create a hazardous condition such as fire, electric shock or personal injury. To reduce these risks significantly, use this device
only in the manner intended by the manufacturer. If you have questions about proper usage of this device, call Tjernlund Products.
Always disconnect the AireShare™ Ventilator from its power source before installation and servicing.
IMPORTANT: An in depth investigation of the wall layout is required prior to installation. Avoid a stud wall section that is a path for
plumbing supply lines, drains and vents. Avoid a stud wall section that is insulated or being used as a return air duct for a forced air
system. If stud walls are constructed with metal studs the Diffuser must be mounted within 3” of the Blower opening since metal studs
typically are not solid throughout. If diffuser is not mounted within 3” of Blower any metal stud openings must be plugged or sealed.

• The AireShare™ may not be used to exhaust hazardous or explosive materials or vapors.
• The AireShare™ may not be installed in a ceiling.
• The AireShare™ may not be installed in an outside wall.
• The AireShare™ may not be installed in a wall rated as a “fire wall.”
• The AireShare™ may not be used to move air from one floor (story) to another floor.
• The AireShare™ may not be used to move moisture-laden air from sources such as bathrooms
and kitchens.
• The AireShare™ may not be used in a window.
WARNING: To reduce the risk of fire, electrical shock and injury to persons, the AireShare™ must
be installed with the AS1 Diffuser that was provided with the AS1. Do not use this product without
the AS1 Diffuser or with any Diffuser other than the AS1 Diffuser.
WARNING: To reduce the risk of fire or electrical shock, do not use this fan with any solid state
speed control devices.
Disrupt power at circuit breaker to outlets within the stud wall you will be working.
When sawing through sheetrock you must stop if you detect the saw blade coming in contact with any wiring or plumbing. Investigate
further to determine if it is possible to safely continue to use this wall cavity space. Switch to another stud wall cavity if necessary.
BEFORE YOU START:
Determine the stud wall section that you want to use to mount the Blower and Diffuser. It may be preferable to select a stud wall section
that contains an electrical outlet for wiring. IMPORTANT: Wall studs must be spaced a minimum of 16” o.c., (See Diagram A). Mark
inside edges of studs the AireshareTM will be installed between and verify there is at least 14” between the inside edges. Slide a stud
finder down the wall between the studs to verify the stud wall cavity is completely open, (See Diagram B).

INSTALLING DISCHARGE DIFFUSER
IMPORTANT: Install Diffuser first if mounting the Blower down low and the Diffuser high so sheetrock from the
Diffuser cut out does not fall into wall cavity and damage Blower. Install the Blower first if mounting the Blower high
and Diffuser low so sheetrock from the Blower cut out does not fall into wall cavity and damage Diffuser.
NOTE: Typical installations will have the Diffuser high and the Blower low, but there may be instances where it
is desirable to have the Blower mounted high and the Diffuser low to take air from the ceiling level.
1. Determine if you would like a high or low discharge. The Diffuser may be mounted as close as 3" above the top
of Blower cut out opening or as close as 3" to the ceiling.
2. Level and mark a line between studs where you want the top of the Diffuser, (See Diagram C)
3. Using a hand sheetrock saw carefully make a horizontal cut along the line. Cut the sheetrock completely until you
come in contact with the opposite stud. NOTE: If studs are spaced greater than 16” o.c., the horizontal cut line
should not exceed 14”, (See Diagram D).

4. Cut out Diffuser template on dashed lines. Align the top of template with the wall cut and center it so that there is an equal space
between the right and left edges of the template and ends of the cut in the sheetrock. Mark all 4 corners of template, connect with
a straight edge and cut Diffuser opening in wall (Diffuser opening should be 1 1/4” high x 13 5/8” wide), (See Diagram E).
5. Insert Diffuser with the air scoop on the back pointing towards the Blower. Adjust tangs on the sides if necessary to secure a tight fit
into the wall opening, (See Diagram F).
BLOWER INSTALLATION
IMPORTANT: Install Diffuser first if mounting the Blower down low and the Diffuser high so sheetrock from the Diffuser cut out does not
fall into wall cavity and damage Blower. Install the Blower first if mounting the Blower high and Diffuser low so sheetrock from the
Blower cut out does not fall into wall cavity and damage Diffuser.
NOTE: Typical installations will have the Diffuser high and the Blower low, but there may be instances where it is desirable to have
the Blower mounted high and the Diffuser low to take air from the ceiling level.
1. If installing in a stud wall section with an electrical outlet, place blower Intake Grille in desired position on stud wall verifying that the
bottom edge is above floor molding and that the top edge is below the bottom of any electrical outlet cover. Level top edge and mark
wall through the two mounting holes. NOTE: This is assuming the Blower is mounted down low and the Diffuser high., (See Diagram G).
If installing the Blower up high and the Diffuser low, the top of the blower Intake Grille must be mounted at least 2” below the ceiling.
2. Use a level to draw a vertical plumb line up 2 7/16” inches from each marked hole. Connect the top of the lines using a straight edge,
(See Diagram H).
3. Using a hand sheet rock saw carefully make a horizontal cut along the line going away from outlet. Cut the sheetrock completely until
you come in contact with the opposite stud. NOTE: If studs are spaced greater than 16” o.c., the horizontal cut line should not
exceed 14 1/2”, (See Diagram I).
5. Align the top of AS1 Blower template with the wall cut and center it so that there is an equal space between the right and left edges
of the template and ends of the cut in the sheetrock. Mark all 4 corners of template, connect with a straight edge and cut rectangular
opening in wall (Model AS1 Blower opening should be 4 7/8” high x 13 7/8” wide), (See Diagram J).
6. Provide a switched 120 VAC power source with leads long enough to connect to the motor leads of the AireShare™ while it is posi-
tioned just outside Blower opening cut in sheetrock, (See Diagram K).
7. Carefully insert the Blower into the cutout. Level the top flange and mark the larger Blower flange mounting holes. Using the provided
wood screws, secure the blower to the wall studs. Use provided wall anchors if not installing into studs, (See Diagram L).
