B. LOCATION REQUIREMENTS

The model ADG-464 dryer requires 36-inches (91.44 cm) of space on each side of the dryer and 36-inches
(91.44 cm) of space behind the unit for ease of maintenance and tilting. The dryer

must be

leveled for proper

operation. If shimming is required, put (24.13 cm) 9-1/2” x 9-1/2” (24.13 cm) metal shims under the base feet.
The dryer

must be

lagged to the floor.

IMPORTANT

: Dryer

should be

located where a minimum amount of exhaust duct will be necessary.

1. The dryer

must be

installed with a proper exhaust duct connecton to the outside.

2. The dryer

must be

installed with provisions for adequate combustion and make-up air supply.

CAUTION:

This dryer produces combustible lint and

must be

exhausted to the outdoors. Every 6

months, inspect the exhaust ducting and remove any lint build up.
