AIRESHARETMROOM-TO-ROOM TRANSFER FAN

MODEL AS2

©2014 TJERNLUND PRODUCTS, INC. ALL RIGHTS RESERVED P/N: 8504213

DESCRIPTION

The Tjernlund AireShare™ Room-to-Room Transfer fans 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. In addi­tion, locating the Grille and Diffuser, one high the other low, prevents the transfer of light and sound between these adjacent rooms.

AS2 SPECIFICATIONS & COMPONENTS

GENERAL INFORMATION

Every Tjernlund AireShare™ Room-to-Room Transfer fan 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.

SPEED SELECTION ADVICE

Since it is impractical to calculate heating and cooling loads for the variety of geographic areas, construction methods and the tempera­ture of transferred air we base our model selection advice on providing a minimum of 3 Air Changes/Hour (ACH) to the target room.
Door under-cuts or pressure relief transfer grilles in the target room are necessary for proper AireShare performance.

(AireShare CFM x 60) / (L x W x H of target room) = ACH NOTE: Aireshare CFM is 110 on High, 95 on Med and 80 on Low

3-4 Air Changes/hour (ACH) recommended for best temperature equalization.

4-5 Air Changes/hour (ACH) recommended for rooms with high cooling or heating loads. Examples include rooms with extensive out­side walls, windows, over tuck under garages or in extreme climates. More than one AireShare transfer fan can be installed to reach
desired number of air changes for large spaces.

INSTALLATION RESTRICTIONS

The AireShare™ Transfer fan must be installed by a qualified installer in accordance with these instructions and all local codes, includ­ing fire-rated construction. In their absence, install in accordance with the latest editions of the International Residential Code and
International Electrical Code. Improper installation 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.

Always disconnect the AireShare™ Transfer fan 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, order Tjernlund Model DK2 Duct Kit or seal all metal stud openings.

• The AireShare™ is for general ventilating use only. Do not use 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. (Ne pas installer pres d'un apparel.)

• The AireShare™ may not be used in a window. (Ne pas utilliser dans une penetre.)

WARNING: To reduce the risk of fire, electrical shock and injury to persons, the AireShare™ must
be installed with the Diffuser that was provided. Do not use this product with any Diffuser other than
the AS2 Diffuser.

WARNING: To reduce the risk of fire or electrical shock, do not use this fan with any solid state speed
control devices. (Avertissment: Ne Convient pas a Des Regulaters De Vitesse a Semi-Conducteurs.)

Disrupt power at circuit breaker to outlets and switches within the stud wall you will be working.

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 Aireshare

TM

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 help verify the stud wall cavity is completely open, (See Diagram B).

TOOLS REQUIRED

Hand Sheetrock Saw Phillips & Straight Screwdrivers Level Tape Measure Utility Knife or Scissors Wire Stripper

INSTALLING DISCHARGE DIFFUSER

WARNING: Disrupt power at circuit breaker to outlets and switches 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.

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.

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.

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 13 5/8”, (See Diagram D).
