12 American Dryer Corp. 113063-11
D. FRESH AIR SUPPLY REQUIREMENTS
This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in
the national installation regulations.
The air supply (make-up air) must be given careful consideration to assure proper performance of each dryer.
An unrestricted source of air is necessary for each dryer. As a general rule, an unrestricted air entrance from
the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.14 square meters) is required for each dryer. If
registers or louvers are installed over the openings, then the area must be increased. It
is not necessary to have
a separate make-up air opening for each dryer. Common make-up air openings are acceptable. However, they
must be set up in such a manner that the make-up air is distributed equally to the dryers. The dryer must be
installed with provisions for adequate combustion and make-up air supply.
EXAMPLE: For a bank of eight (8) dryers, two (2) unrestricted openings measuring 2 feet
by 3 feet (0.61 meters by 0.91 meters), (6 square feet [0.56 square meters]) are acceptable.
IMPORTANT: Make-up air openings should not be located in an area directly near where exhaust
vents exit the building.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive
altitudes or predominantly low pressure areas.
IMPORTANT: Make-up air must be provided from a source free of dry cleaning solvent fumes.
Make-up air that is contaminated by dry cleaning solvent fumes will result in
irreparable damage to the motors and other dryer components.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
