INDOOR INSTALLATION - WALL MOUNTING
For maximum efficiency, the unit should be mounted no
higher than 8'0" above the floor.
1. Install the DIPLOMAT/MARK II Series Air Door so that
nothing interferes with the curtain of air when it is
deflected 20° to either side. If the air stream strikes any
obstruction, i.e. the top edge of the doorway, a structural
beam, a door opening device, etc., its efficiency will be
greatly reduced. See Figure 2.
2.
The lower lip of the mounting plate should be no more
than 1" above the door open- ing when the unit is
mounted flush to the wall. If the air door must be
mounted higher, it must be spaced out from the wall
for every inch the unit is above the
the best performance, any void between the air door and
the wall must be sealed (use foam, plastics or a similar
packing). See Figure 3.
3. Do not block the air flow to or from the unit since this
could cause overheating. On electrically heated units
there should be:
A) a minimum clearance of at least 4" between the side
of the unit and any combustible material if the unit is
enclosed in the ceiling or a decorative cover.
B) a minimum clearance of 8" between the top of the
unit and the ceiling in order to service the junction
box(es).
C) do not install less than six feet (or 1.8 meters) from
the floor to the unit. See Figure 2.

WALL PREPARATION
1. Position and center the mounting plate over the door
opening. The mounting plate must be positioned with the
45° lip and the rubber vibration gasket on top. Four (4)
slotted mounting holes are provided on the mounting
plate. See Figure 4.
2. Mark the wall in the center of each mounting plate hole.
The wall must provide sufficient support for the air door.
The mounting hardware (supplied by others) must be
capable of supporting a minimum of three times the net
weight of the air door. See Weight Chart, Table 1. If the
location of the marks on the wall do not provide suitable
support, mark and drill additional holes.
3. Drill the four holes as marked on the wall and attach the
mounting plate with anchors (if used) and the four
mounting screws (provided by others).
