TJERNLUND AIRESHARE R2RP Manuel utilisateur
DESCRIPTION
The Tjernlund AireShare™ Room-to-Room Ventilators distribute air from one 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 typical-
ly are not solid throughout. If diffuser is not mounted within 3” of Blower any metal stud openings must be plugged or sealed.

WARNING: To reduce the risk of fire, electrical shock and injury to persons, the
AireShare™ must be installed with the R2RP Diffuser that was provided with the R2RP.
Do not use this product without the R2RP Diffuser or with any Diffuser other than the
R2RP 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. You must select a
stud wall section that contains an electrical outlet, (See Diagram A). IMPORTANT: Wall studs must be
spaced a minimum of 16” o.c., (See Diagram B). 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 C).
TOOLS REQUIRED
Sheetrock Saw Philips & Straight Screwdrivers Level Tape Measure Utility Knife or Scissors
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: Since electrical outlets are usually not up high, typical installations of the model R2RP will have the Diffuser
high and the Blower low, but there may be instances where it is desireable to have the Blower mounted
high and the Diffuser low to take air from the ceiling level.
1.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 for top of the Diffuser cut out, (See Diagram D)
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 E).

4. Cut 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 F).
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 G).
BLOWER INSTALLATION
IMPORTANT: Install Diffuser first when 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.
1. You must select a stud wall section that contains an electrical outlet, (See Diagram H). Mark a vertical line down the side of the outlet
box opposite stud. Mark a spot 3/4” above electrical outlet top mounting screw on outlet side opposite stud, (See Diagram H).
2. From the mark made in Step 1, use a level to draw a horizontal line across to opposite stud, (See Diagram I).
3. Using a hand sheet rock saw carefully make a horizontal cut along the line going away from outlet. Cut the sheetrock 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 12 1/2”, (See Diagram J).
4. Align the top corner of R2RP Blower template with horizontal wall cut and vertical line. Mark all 4 corners of template, connect with a
straight edge and cut rectangular opening in wall (Model R2RP Blower opening should be 4 7/8” high x 12” wide), (See Diagram K).
5. With the Blower discharge pointing towards Diffuser rotate the mounting flange so that the electrical outlet cutout is positioned on the
side of the Blower housing nearest the electrical outlet. With the bent tabs facing the front of the Blower, slide the mounting flange
from the rear of the Blower to the front until the four tabs line up with the holes in the Blower housing. Secure Blower housing to
mounting flange with included 8/32 self tapping screws. NOTE: If electrical outlet is on the right side of Blower, loosen (2) power
switch bracket screws and slide power switch bracket completely over to the right to allow for proper alignment of switch opening on
Grille. Tighten (2) switch bracket screws, (See Diagram L).
6. 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 M).
