AIRESHARETMLEVEL 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

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 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 Products.

Always disconnect the AireShare™ Ventilator from its power source before installation and servicing.
IMPORTANT: An in depth investigation of the floor joist/truss layout is required prior to installation. Avoid a floor/ceiling cavity that is a

path for plumbing supply lines, drains, vents or ductwork. Also confirm foundation block and upstairs walls do not obstruct installation.

• The AireShare™ may not be used to exhaust hazardous or explosive materials or vapors.

• The AireShare™ may not be used in kitchens or move moisture-laden air from sources such as bathrooms and kitchens.

• The AireShare™ may not be used to move air from from a utility room containing gas or oil fuel heating equipment.
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 con­firm 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.

INSTALLATION

THE FOLLOWING STEPS ARE FOR AN UPFLOW INSTALLATION

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).
