D. FRESH AIR SUPPLY

The MDG-50 air supply (makeup air) must be given careful consideration to assure 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 1-1/2 square feet is required for each dryer. If registers or louvers are installed over the openings, then the area must be increased. It is not necessary to have a separate makeup air openings for each dryer. Common makeup air openings are acceptable. However, they must be set up in such a manner that the makeup air is distributed equally to the dryers.

EXAMPLE: For a bank of eight (8) dryers, twelve (12) square feet; two (2) unrestricted openings measuring 2 feet by 3 feet (6 square feet each) is acceptable.

IMPORTANT: 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 altitudes or predominantly low pressure areas.

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 motors and other dryer components.

NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
