Tmi IBD-3-60-1-SS Installation Manual

Wall Mounting

1. Remove the mounting plate locking screws from the back bottom corners of
the unit and detach the mounting plate from the back of the unit. Figure 1.

2. Keeping the mounting plate level, center it over the doorway opening. Be sure
the lipped edge of the plate is at the top. Figure 2. Note: The bottom edge of
the mounting plate should be no more than 108'' from the floor.

Never install your Air-Pro Air Door in an adverse environment,
such as, near splashing water, excess steam, explosive or
corrosive gases.

3. Mark the pre-drilled holes, remove the plate and check to
make sure you are tying into firm supporting material, i.e.
studs, header or block. Note: There should be at least 4
secure mounting holes used. If not, drill 4 new holes in the
mounting plate to accommodate a secure attachment. Drill the
wall holes.

4. Attach the mounting plate. (Screws not supplied)

Solid Wall Mounting

1. Perform the first two steps under “Wall Mounting” (see above).

2. Mark the 4 outside pre-drilled holes and remove the plate.

3. Drill the 4 anchor holes and place anchors in each hole.

4. Attach the mounting plate. (Screws not supplied)

Ceiling Mounting

If mounting the air door to the ceiling is necessary, you will need to
order our mounting brackets (optional). Also, 4 threaded rods
(supplied by others) will be needed.

1. Secure the 4 threaded rods to the ceiling at the proper distance
from the floor taking the height of the air door unit into consideration.

2. Using a hex bolt, washer and nut, attach each bracket to the
mounting plate using the pre-drilled holes. Make sure the
lipped edge of the plate is at the top.

3. Holding the assembly in place, fasten the rods to the
bracket collars. Figure 4.

By dropping the Air Door on its side during shipping the blower wheels may come out of the side bushing. This must be corrected prior
to operating the unit. 1) Remove the intake grill and the four screws on the side of the unit to remove the end plate. 2) Loosen the
screw that attaches the blower wheels to the motor shaft and remove the blower wheels. 3) Insert the metal wheel from the end of the
blower wheels into the rubber bushing. 4) Slide the blower wheels into the side of the unit over the motor shaft and reattach the four
screws to the side of the unit. 5) Tighten the blower wheels to the motor shaft and replace the intake grill.

IMPORTANT

Once your air door has been installed, it will be necessary to adjust the air flow. With the door

all the way open, turn the unit on “High,”, find the air stream split by holding a square piece of

light weight cloth by its corners in the stream of air and move it back and forth (inside and

outside), approximately 6" from the floor. The cloth will show the flow pattern and will allow

you to make the proper adjustments to the directional vane for maximum efficiency. If your unit

is properly adjusted, the split should be just outside the threshold with the top of the air

current being about 2' from the floor.

The air flow angle can easily be adjusted by turning the directional vane using your hand. No

tools are needed. The angle of the air flow depends on the height of the door and is normally

between 5° and 10°.

It should never exceed 20°.

If the air current is too severe or exceeds the 2' level, you can turn the power switch to “Low.”

Attaching the Air Door to the Mounting Plate

After the Mounting Plate had been securely attached using one of the mounting methods, the air door must be attached to the mounting plate.

1. Lift the unit, into place
with the outlet nozzle
at the bottom and the
intake grill facing
away from the
mounting plate.

2. Slip the unit over the
mounting plate lip.

3. Gently push the
unit down so it
rests on the lip.

4. Replace all the
mounting plate
screws and firmly
tighten.

4. Plug the unit
into a properly
grounded 3
prong, 120 V
electrical outlet.

SPECIAL APPLICATIONS

Mounting Above the Ceiling

1. Mount the Air Door using the “Wall Mounting” method (see page 1).

2. The intake vent should be at least 36'' away from the outlet vent.

3. It is extremely important to fabricate the intake ductwork so it encapsulates the
entire intake grill. Figure 5.

1. Mount the Air Doors using any
of the mounting methods
(see page 1).

2. The space between units
should be between 1'' and 2''.
