B. Tandem Mounting Brackets connect the end plates of the
units to be joined. Two brackets are required. Ideally, the
units are joined together before the lower unit is bolted to
the floor.
C. Using (4) ½ - 13 x 1” bolts, attach the Tandem Mounting
Brackets to the inside of one of the unit’s end plates as
shown in
Figure 8
.
D. Slide the end plate of the next unit over the brackets
installed in Step C and attach using (4) additional ½” bolts as
shown in
Figure 9
.
E. Assemble Floor Mounting Brackets to lower unit and attach
to floor per steps C and D of Section V.

VII. ELECTRICAL CONNECTIONS
All electrical wiring and connections
MUST
be performed
by qualified personnel in accordance with the National
Electrical Code ANSI/NFPA No. 70 (latest edition) or, in Canada,
the Canadian Electrical Code, Part 1-C.S.A. Standard C22.1, and
local codes and regulations.

IV. SUSPENDED MOUNTING
A. Suspended mounting works well with the majority of door
types commonly found in an industrial setting, such as roll-
up doors, “high rise” track doors, “low-rise” turn back doors,
and “high-rise” turn back doors.
B. The IDC12/IDC14 Series end plates are equipped with ½”
holes for suspended mounting. The unit may be suspended
using a minimum ³/8” suspension rod
(Figure 3)
, or using
³/8” suspension rods and extension brackets (available from
Berner).
See Figure 4.

V. VERTICAL MOUNTING
A. Vertical mounting works well when the opening is taller
than it is wide, or when the door type prevents a typical
“over-door” mounting position.
B. Optional Floor Mounting Brackets (available from Berner)
bolt to the unit end plate, and provide a rigid base to attach
the unit to the floor. Two Brackets are required.
C. To vertically mount a IDC12/IDC14 Series unit using optional
Floor Mounting Brackets, bolt brackets on the inside of the
end plate with (4) ½ - 13 bolts as shown in
Figure 5
.
D. Position the unit vertically in its intended position and
anchor it to the floor with a minimum ³/8” fastener.
See
Figure 6
.
E.
To improve the stability of the installation, it is required
that the top of the unit be attached to the wall. A common
approach is to attach a minimum length of
³/8”
threaded rod
through one of the open mounting holes in the top end
plate and affix the other end of the rod to the wall.
See Figure 7

VI. TANDEM MOUNTING BRACKETS
(For Vertical Mount Installation)
A. Optional Tandem Mounting Brackets (available from Berner)
are used to join two
air curtains together in a vertical
application when the door height exceeds 16’.
