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 the
make-up air opening(s) are too close to the exhaust outlet, lint and fumes may be
drawn back into the dryer through these openings.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
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
ALL
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, a total make-up air opening of 16 square feet (1.49 square
meters) is required. Two (2) openings measuring 2 feet by 4 feet (0.61 meters by 1.23
meters) 16 square feet (1.49 square meters) is acceptable.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive
altitudes or predominantly low pressure areas.
