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.
Air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An
unrestricted source of 400 cfm (11.3 cmm) is necessary for each dryer. A n 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. This area must be
enlarged if louvers or registers cover the opening. 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. For example, for a bank of eight (8) dryers, a total make-up air
opening of 12 square feet (1.15 square meters) is required. Two (2) openings measuring 2 feet by 3 feet (0.61 meters
by 0.91 meters) 6 square feet (0.56 square meters) are acceptable. The dryer must be installed with provisions for
adequate combustion and make-up air supply.
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.
IMPORTANT: Make-up air openings should not be located near ductwork exhaust outlets. If
make-up air openings are too close to the exhaust outlet, lint and fumes may be drawn
back into the dryer area through these openings.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
