F. FRESH AIR SUPPLY REQUIREMENTS

When the dryer is operating, it draws in room air, heats this air through the tumbler (basket), and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If makeup air is inadequate, drying time and efficiency will be adversely affected, and safety will be compromised. Premature component failure may result.

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. An airflow of 13,000 cfm per minute (368 cmm) (cubic meters per minute) must be supplied to each dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum twenty (20) square feet (6.096 m2) is required for each dryer.

To compensate for the use of registers or louvres used over the openings, the makeup air area must be increased by approximately thirty-three percent (33%). Makeup 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 altitude or predominantly low pressure areas. The dryer must be installed with provisions for adequate combustion and make-up air supply.

IMPORTANT: Makeup air must be provided from a source free of dry cleaning solvent fumes. Makeup 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.
