113409- 2 www.amdry.com 11

D. FRESH AIR SUPPLY REQUIREMENTS

When the dryer is operating, it draws in room air, heats it, passes this air through the 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
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. As a general rule, an unrestricted air entrance from the outdoors (atmosphere)
of a minimum of 2.7 square feet (0.25 square meters) is required for each dryer. (Based on 1 square inch per 1,000 Btu.)

To compensate for the use of registers or louvers used over the openings, this make-up air 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.

is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are acceptable.

It
However, they must be set up in such a manner that the make-up air is distributed equally to ALL the dryers.

EXAMPLE: For a bank of six (6) dryers, two (2) unrestricted openings measuring 3 feet by 3 feet (0.91 meters by 0.91

meters) are acceptable.

will be adversely affected. Ignition problems and sail switch “fluttering” problems may

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.
