INDOOR AND OUTDOOR MOUNTING FOR CURTRON AIR DOORS
INDOOR MOUNTING - Environmental/Insect/ Dust Control
OUTDOOR MOUNTING - Insect/ Dust Control
NOTE: The air door is weatherproof; therefore, no special covering is required
for outdoor mounting.
IMPORTANT: A minimum of 4” is required above the top of the air door for the
installation and removal of the cover housing.
1. Install the air door so that nothing interferes with the air stream when it is
deflected 20° to either side. If the air stream strikes any obstruction, for
example, the top edge of the doorway, a structural beam or a door opening
device, its efficiency will be reduced. See Figure 1. On electrically heated
units there should be 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.
2. The outlet nozzle should be no more than 1” above the top of the doorway
opening. See Figure 2A.
If the air door must be mounted higher, then it should be spaced out from
the wall 3/8” for every inch the unit is moved up above the doorway opening. Any void between the air door and the wall must be sealed (use foam,
plastics or similar packing) for best performance. See Figure 2B.
