CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6 months,
inspect the exhaust ducting and remove any lint buildup.
IMPORTANT: Dryer must be installed in a location/environment, which the ambient temperature
remains between 40° F (4.44° C) and 130° F (54.44° C).
C. FRESH AIR SUPPLY REQUIREMENTS
When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and exhausts it
out of the building. Therefore, the room air must be continually replenished from the outdoors. If the make-up air is
inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and sail switch “fluttering”
problems may result, as well as premature motor failure from overheating.
The dryer must be installed with provisions for adequate combustion and make-up air supply.
Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. An unrestricted
source of air is necessary for each dryer. An airflow of 6,500 cfm (cubic feet per minute) (184.05 cmm [cubic meters
per minute]) must be supplied to each gas dryer and 8,500 cfm (240.69 cmm) for each steam dryer. As a general rule,
an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 6 square feet (0.56 square meters) is
required for each gas dryer and a minimum of 8 square feet (0.74 square meters) for each steam dryer.
To compensate for the use of registers or louvers used over the openings, this make-up air area must be increased by
approximately thirty-three percent (33%). Make-up air openings should not be located in an area directly near where
exhaust vents exit the building.
It is not necessary to have a separate make-up air opening for each dryer. Common make-up openings are acceptable.
However, they must be set up in such a manner that the make-up air is distributed equally to ALL the dryers.
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.
