FIGURE 3 - Positioning of Mounting Plate
D. Anchor the wall mounting plate over the door opening with
the mounting tabs pointing upwards.
E. Raise the unit over the door (air discharge nozzle facing down)
and on to the mounting plate. First, tilt the unit upward
matching the holes in the frame with the tabs on the mount-
ing plate. See FIGURE 4.
F. Lower the unit into place allowing it to rest on the mounting
plate. The unit flange should rest above the mounting plate
flange.
G. After the unit is securely seated to the mounting plate, install
the locking screws along the bottom flange. See FIGURE 4.
IV. SUSPENDED MOUNTING
(Ceiling Suspension)
A. When the unit is top mounted, the wall mounting plate is
designed to store on the back of unit for future use.
B. Four (4) factory installed #10-24 threaded inserts are located
on the top of the unit for top suspension mounting.
See Figure 5
C. Determine the exact mounting location of the air door unit.
D. The top of the unit is provided with an electrical knockout
for power connection. Remove the wiring tray
compartment cover. Remove the knockout and attach
necessary electrical hardware. Save the wiring diagram
found inside of wiring tray.
E. Attach #10-24 threaded rods, or other suitable hardware to
the top mounted threaded inserts.

V. ELECTRICAL CONNECTIONS
All electrical wiring and connections MUST be performed by
qualified 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 TABLE 2
B. All field 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 wiring compartment cover located on the top of
the unit. See FIGURE 6
D. A ½" knockout is provided next to the wiring compartment
