AIRESHARETM LEVEL TO LEVEL VENTILATOR
MODEL ASLL
©2009 TJERNLUND PRODUCTS, INC. ALL RIGHTS RESERVED P/N: 8504156
DESCRIPTION
The AireShare™ Level to Level Ventilators distribute air from one conditioned space to another. Virtually every home has temperature
differentials on different levels of the house. The AireShare™ moves air from one level of the house to a room on another level of the
house that is uncomfortably hot or cold. This air movement helps to destratify stagnant air in homes, improve ventilation rates and make
both rooms more comfortable.
ASLL SPECIFICATIONS & COMPONENTS
GENERAL INFORMATION
Every Tjernlund AireShare™ Level to Level 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

WARNING: Disconnect power to the ASLL before servicing. To reduce the risk of fire, electrical shock and injury to persons, the
AireShare™ must be installed with the ASLL Floor grille that was provided with the ASLL.
WARNING: To reduce the risk of fire or electrical shock, do not use this fan with any solid state speed control devices.
WARNING: To reduce the risk of fire, electric shock, or injury to persons, observe the following:
a. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.
b. Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means to prevent power
from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent
warning device, such as a tag, to the service panel.
c. Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards,
including fire-rated construction.
d. When cutting or drilling into floor, wall or ceiling areas, do not damage electrical wiring and other hidden utilities.
Disrupt power at circuit breaker to outlets near the joist/truss area you will be working in.
When sawing through sheetrock or floor, immediately 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
joist/truss cavity. Switch to another joist/truss cavity if necessary.
BEFORE YOU START:
Determine the joist/truss cavity mounting location. If you are wiring to an existing outlet it is best to select a
joist/truss section that contains an electrical outlet for wiring. IMPORTANT: Direction of joist/truss might
determine which direction the ASLL can be installed. Review ASLL dimensions and minimum and
maximum expansion of sleeve before installing, (See Diagram A). Use a stud finder to verify joist/truss
location and direction.
TOOLS REQUIRED
Sheetrock Saw • Phillips Screwdriver • Drill • Tape Measure • Utility Knife • Wire Stripper • Stud Finder (required if ceiling is finished)
3/8” drill bit & 1/4” drill bit 2” longer than joist/truss thickness (long bit not required if ceiling is unfinished) • Jig Saw / Reciprocating Saw
INSTALLATION
PRE-INSTALLATION INSPECTION
IMPORTANT: An in depth investigation of the floor joist/truss layout is required prior to installa-
tion. Avoid a section that is a path for plumbing supply lines, drains, vents or ductwork. Also con-
firm foundation block or upstairs walls do not obstruct installation. If wiring to an existing outlet
using surface wiring, it is best to select a joist/truss section that contains an electrical outlet to
wire into.
Determine if the installation is a downflow or upflow application. If ASLL will discharge air up to
the level above it is upflow. If ASLL will discharge air down to a lower level it is downflow.
1. Proceed to step 2 if ceiling is unfinished. If ceiling is finished use a stud finder to locate the inside edges of the joist/truss ASLL will
be installed between. Apply masking tape on ceiling along joist/trusses in the desired location ASLL will be installed in. Make sure a
proper analysis as noted above has taken place before cutting hole in ceiling. In the center of the tape cut a 3” x 3” inspection hole
to review the intended installation area using a flashlight and small mirror if necessary, (See Diagram B).
NOTE: The following installation illustrations show the upper level floor with carpeting.
2. If floor above has carpeting it may be desirable to pull carpeting back if possible. If it is a good installation area, slowly drill a small
pilot hole with a 1/4” drill bit through the 3” x 3” inspection hole or center of joist/truss area up through subfloor. Drill bit might cause
carpet to unravel so be cautious. Once you go through subfloor reverse out of the hole. Use an extended screw driver or scratch awl
to push through the carpet above.

3. Place ASLL Outer Sleeve template center alignment hole over drill bit or screw driver. Align template cutout lines parallel with
baseboard and tape template to floor, (See Diagram C). Use a utility knife and cut out carpeting and pad along Outer Sleeve
template lines denoted, (See Diagram D).
4. Drill the 4 corners out on floor with a 3/8” drill bit and saw opening out using a jig saw or reciprocating saw. The final rough-in opening in
the floor for an Upflow application must measure 4 5/16” x 12 5/16” for Outer Sleeve. IMPORTANT: Rough-in openings must
not exceed dimensions provided or Outer Sleeve flange may fall through opening, (See Diagram E).
5. Proceed to step 8 if ceiling below is unfinished. Slide the Outer Sleeve through the floor. Using a 1/4” long drill bit, follow the corners of
the Outer Sleeve straight down and drill 4 holes through the ceiling material below, (See Diagram F). Connect the 4 holes on the ceiling
below with a straight edge and compare the dimensions on the ceiling to Blower Housing template dimensions which measure 4 1/16” x
12 5/16”, See Diagram G).
6. If ceiling is sheetrock use a sheetrock saw and follow the lines from step 5 and cut out ceiling opening, (See Diagram G). If ceiling is
not sheetrock, use a jig saw or reciprocating saw. IMPORTANT: Both openings should be directly centered above one another.
7. If ceiling is sheetrock or ceiling tile, slide sheetrock mounting brackets over sheet rock ends. The 2 large holes in brackets must face
down, (See Diagram H). IMPORTANT: If using ceiling tile, it must be able to support 8 pounds to support the ASLL blower. If ceiling
tile is not adequate enough to support the ASLL then the ASLL must be framed in and properly supported by ceiling track.
8. Use a rod with wire attached to ASLL Blower Housing mounting bracket to suspend ASLL blower from floor above while
wiring, (See Diagram I).
9. Supply electrical power through ceiling opening on the side of ASLL where power will enter unit. See “Wiring” section for wiring
specifics. Use provided strain relief bushing for standard 14-2 w/ground NM-B nonmetallic sheathed cable (Romex) and snap into
place in 7/8” knockout on ASLL electrical box with about 6-8” of wire pushed into ASLL electrical box, (See Diagram J). Push wire up
tight against ASLL Blower Housing and slide the ASLL up through the hole in the ceiling until the flange of the ASLL blower section
meets the ceiling, (See Diagram K).

10. Using the (4) provided black screws, align holes on ASLL Blower Housing mounting bracket with holes in sheetrock mounting brack-
et (utilized if ceiling is sheetrock or ceiling tile). Install the (4) screws straight up. The screws must grip the sheetrock mounting
bracket small grip hole. Do not over tighten screws, (See Diagram L). If ceiling is unfinished cut (2) pieces from floor cutout
material and secure each piece to the joist/truss and install (4) screws in ASLL Blower Housing mounting bracket, (See Diagram L).
11. Wire the ASLL as illustrated in the “Wiring” section. Push the wires into the ASLL electrical box and install electrical box cover
and ceiling grille with the provided screws, (See Diagram M). Ceiling grille may be painted if desired.
12. IMPORTANT: If the combined width of the Joist/Truss thickness, ceiling and subfloor is over 13”, adhere both air flow leakage stickers
over electrical relief slot opening in Outer Sleeve to prevent air leakage into joist/truss cavity, (See Diagram N).
13. Install the Outer Sleeve in floor. CAUTION: When installing Outer Sleeve make sure electrical relief opening is on the side electrical
enters ASLL, (See Diagram O).
14. Unit can be operated by switching the on/off switch below floor grille, (See Diagram P). ASLL can also be wired into a 120 VAC wall
switch or thermostat if desired, see “Wiring” for details. Insert the floor grille.
IMPORTANT: An in depth investigation of the floor joist/truss layout is required prior to installation. Avoid a joist/truss cavity that is a
path for plumbing supply lines, drains, vents or ductwork. Also confirm foundation block and upstairs walls do not obstruct installation. If
wiring to an existing outlet, it is best to select a joist/truss section that contains an electrical outlet for wiring.

1. Proceed to step 2 if ceiling is unfinished. If ceiling is finished use a stud finder to locate the inside edges of the joist/truss cavity the
ASLL will be installed between. Apply masking tape on ceiling along joist/trusses in the desired location ASLL will be installed in.
Make sure a proper analysis as noted above has taken place before cutting hole in ceiling. In the center of the tape cut a 3” x 3”
inspection hole to review the intended installation area using a flashlight and small mirror if necessary, (See Diagram B1).
NOTE: The following installation illustrations show the upper level floor with carpeting.
2. If floor above has carpeting it may be desirable to pull carpeting back if possible. If it is a good installation area, slowly drill a small
pilot hole with a 1/4” drill bit through the 3” x 3” inspection hole or center of joist/truss up through subfloor. Drill bit might cause car-
pet to unravel so be cautious. Once you go through subfloor reverse out of the hole. Use an extended screw driver or scratch awl
to push through the carpet above.
3. Place ASLL Blower Housing template center alignment hole over drill bit or screw driver. Align template cutout lines parallel with
baseboard and tape template to floor, (See Diagram C1). Use a utility knife and cut out carpeting and pad along Blower Housing
template lines denoted, (See Diagram D1).
4. Drill the 4 corners out on floor with a 3/8” drill bit and saw opening out using a jig saw or reciprocating saw. The final rough-in opening in
the floor for a Downflow application must measure 4 1/16” x 12 5/16” for Blower Housing. IMPORTANT: Rough-in openings must
not exceed dimensions provided or Blower Housing flange may fall through opening, (See Diagram E1).
5. Proceed to step 7 if ceiling below is unfinished. Using a 1/4” long drill bit, follow the corners of the Blower Housing cutout straight down
and drill 4 holes through the ceiling material below, (See Diagram F1). Connect the 4 holes on the ceiling below with a straight edge and
compare the dimensions on the ceiling to Outer Sleeve template dimensions which measure 4 5/16” x 12 5/16”, (See Diagram G1).
6. If ceiling is sheetrock use a sheetrock saw and follow the lines from step 5 and cut out ceiling opening, (See Diagram G1). If ceiling
is not sheetrock, use a jig saw or reciprocating saw. IMPORTANT: Both openings should be directly centered above one another.
7. Supply electrical power to side of ASLL where power will enter unit. See “Wiring” section for wiring specifics. Use provided strain
relief bushing for standard 14-2 w/ground NM-B nonmetallic sheathed cable (Romex) and snap into place in 7/8” knockout on
