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 any questions, contact the manufacturer.
B. Before servicing or cleaning unit, switch power o 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 qualied person(s) in accordance with all applicable codes and standards, including
re-rated construction.
D. Sucient air is needed for proper combustion and exhausting of gases through the ue (chimney) of fuel burning equipment to prevent
back drafting. Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National Fire
Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and local
code authorities.
E. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.

I. UNCRATING
Carefully examine the carton(s) for damage before opening. If the carton
is damaged, immediately notify shipping company. If the unit(s) were
shipped on wooden skids, remove protective wood and banding straps
securing the carton(s) to the skid. Open the carton(s) and remove all protective packaging. Remove the plastic cover housing by lifting vertically.
Remove and discard four (4) nuts and washers holding the motor/blower
section to the bottom of the carton. Remove motor/blower section from
the carton.
CAUTION: ONLY LIFT THE UNIT BY GRASPING INLET RINGS ON THE
BLOWER HOUSING WITHOUT TOUCHING BLOWER WHEELS.
Immediately verify that the electrical rating nameplate located on the
cover matches electrical power supply available. Retain the shipping
carton(s) until the unit(s) are installed and properly operating.
ACCESSORIES: If the unit(s) were ordered with optional electrical accessories (door switch, control panel, etc.), the accessories may be found in
the carton containing the unit or in a separate carton(s) accompanying
the unit(s). Check all of the cartons/skids for accessories before discarding.
II. MOUNTING INSTRUCTIONS (General)
INDOOR MOUNTING - Environmental/Insect Dust Control
OUTDOOR MOUNTING (Unheated Only) - Insect/Dust Control
The Aristocrat/Star Air Door is designed to be an eective barrier against
cold drafts in the winter and hot air in the summer. To achieve optimum
protection, the unit should be mounted on the inside of the building,
ush to the wall and as close to the top of the door opening as possible.
To ensure peak performance keep air stream free of obstructions.
The Air Door will not perform properly if negative air pressure exists
in the building. Under these conditions, a means for makeup air to
the building must be provided so that the air pressure on both sides
of the opening is in balance.
Before mounting the unit, check the supporting structure to verify that
it has sucient load-carrying capacity to support the weight of the
unit(s). The mounting hardware (supplied by others) should be capable
of supporting a minimum of three (3) times the weight of the unit. See
Table 1.

FIGURE 1 - Air Stream
NOTE: The Air Door is weatherproof, therefore no special covering is
required for outdoor mounting.
IMPORTANT: A minimum of 4” is recommended above the top of the Air
Door for the installation and removal of the cover housing.
A. When determining the mounting location for the unit(s), make sure
that nothing interferes with the curtain of air developed when the
discharge vanes are directed from 0° to 20° toward the door opening.
If the air stream strikes any obstruction (the top edge of the doorway,
a door opening device, etc.), the eectiveness of the unit will be
greatly reduced. See Figure 1.
B. For optimum performance, the bottom of the unit (discharge nozzle)
should be no more than 1” above the top of the door opening with
the unit mounted ush to the wall. If the unit must be mounted
higher, it must be spaced out from the wall ³/₈” for every inch the
unit is above the door opening. For optimum protection, any void
between the Air Door and the wall should be sealed along the full
length of the unit.
See Figure 2.

C. Electric heated units shall:
1. Have a minimum clearance of at least 4” between the sides and
top of the unit and any combustible material.
2. Have a minimum clearance of at least 6’ between the bottom of
the unit and the oor.
3. Be installed indoors only.
D. Proceed to either Section III - WALL MOUNTING, or Section IV
SUSPENDED MOUNTING
III. WALL MOUNTING
To prevent damage to the Air Door during shipping, the unit is shipped
with each blower attached to the back plate by two phillips head screws.
These screws should be removed before installation.
See Figure 3.
FIGURE 3 - Mounting Screws
A. The Aristocrat/Star Series Air Door is equipped with ¼” keyhole
mounting slots on the back of each unit for wall mounting. It is recommended that a minimum of two keyhole slots are used from each
end.
B. Determine the exact mounting location of the Air Door unit.
NOTE: A minimum of 4” is recommended above the unit to
provide clearance for installation and removal of the unit blower
assembly.
C. Choose four (4) keyhole slots that are located where suitable support
is available for the unit. If the keyhole slots are not located where
suitable support is available, drill new holes in the unit backplate
where space is available.
D. Mark the wall in the top center of the keyhole slots or in the center of
the holes drilled.
E. Keyhole Mounting:
Install the mounting hardware (supplied by others), allowing for
space to hang the unit by not fully tightening. Lift and slip the
blower assembly over the mounting hardware by grasping the inlet
rings on the blower housing, without touching the blower wheels.
Tighten the mounting hardware. See Figure 4.
Drilled Mounting Holes:
Lift the blower assembly by grasping the inlet rings on the blower
housing, without touching the blower wheels, and install the mount-
ing hardware (supplied by others) through the drilled holes.
FIGURE 4 - Keyhole Mounting
F. Do not install the cover housing at this time.
G. Proceed to Section V - ELECTRICAL CONNECTIONS.
IV. SUSPENDED MOUNTING (Ceiling Suspension)
NOTE: TWO (2) TOP MOUNTING BRACKETS
(PART#66LWA000TOP)ARE REQUIRED
PER UNIT FOR SUSPENDED MOUNTING.
To prevent damage to the Air Door during shipping,
the unit is shipped with each blower attached to the
back plate by two phillips head screws. These screws
should be removed before installation. See Figure 3.
A. The Aristocrat/Star Series Air Door is equipped with keyhole mount-
ing slots on the back of the unit. The top mounting brackets are
designed to attach to these keyhole slots.
B. Attach the top mounting brackets to the unit using the hardware
provided.
C. Determine the exact mounting location of the Air Door unit.
D. Attach /” threaded rods or other suitable hardware to the coupling
nuts, located on the mounting bracket(s).
E. Do not install the cover housing at this time.
F. Proceed to Section V - ELECTRICAL CONNECTIONS.
V. ELECTRICAL CONNECTIONS
All electrical wiring and connections MUST be performed by qualied
personnel in accordance with the latest edition of the National Electrical
Code ANSI/NFPA No. 70 or, in Canada, the Canadian Electrical Code, Part
1-C.S.A. Standard C22.1 and local codes and regulations.
A. Check the rating nameplate on the unit for supply voltage and
current requirements. A separate line voltage supply with a suitable
branch circuit protection device should be run directly from the
main electrical panel to the unit. A disconnect switch for each branch
circuit is a required part of this installation.
See Tables 2 & 3.
B. All eld wiring must be copper with a minimum insulation of 60° C
within approved conduit. If any of the wire supplied with the unit
must be replaced, it must be replaced with copper wiring with a
minimum insulation of 90° C.
C. Remove the junction box cover located on the right-hand side of the
unit. See Figure 5.
D. Connect all supply and control circuit wires according to the wiring
diagram. To connect wiring from the left-hand side, an optional
knockout is provided.
