Make-Up Air Requirements

It is important that the laundry room has adequate make-up air for the unit(s). A dryer exhausts 180 cfm (measured at back of the unit) and sufficient make-up air must be supplied to replace the air exhaust by the unit.

Make-Up Air Dos and Don’ts

Do

●Supply adequate air for ventilating air and drying air.

NOTE: Each dryer pocket must have 260 cm2

(40 square inches) of unobstructed flow of make-up air for proper operation.

●Energy efficient buildings with low air infiltration rates should be equipped with an air exchanger that can accommodate on demand make-up air needs in the laundry room. These devices can be obtained through your building contractor or building material suppliers.

Don’t

●Draw make-up air from a room containing a gas fired water heater.

●Draw make-up air from a room containing a dry cleaner or a hair salon.

Installation

Exhaust Direction

The dryer can be exhausted to the outdoors through the back, left, right or bottom of the unit.

Unit is shipped from factory ready for rear exhaust; no kits required.

Exhausting the unit through sides or bottom can be accomplished by installing Directional Exhaust Kit 528P3, available as optional equipment at extra cost.
