Exhaust System Maintenance

The dryer unit interior and the complete exhaust system should be inspected after one year of use and cleaned if necessary. Inspect and clean exhaust duct every one to two years as required thereafter. The weather hood should be checked frequently to make sure the dampers move freely, dampers are not pushed in and that nothing has been set against them. This maintenance work should be done by a qualified service person.

WARNING

To reduce the risk of electric shock, disconnect the electrical service to the dryer before cleaning.

Exhausting the dryer unit in hard-to-reach locations can be accomplished by installing the 521P3 Flexible Metal Vent Kit, available as optional equipment at extra cost.

The kit comes in two halves that can be separately attached to the dryer unit, the wall outlet and to each other. Once attached, the dryer can be slid back into position.

Dryer Airflow

Efficient dryer unit operation requires proper dryer airflow. Proper dryer unit airflow can be evaluated by measuring the static pressure.

Static pressure in the dryer unit’s exhaust duct should be no greater than that shown in the chart below. (Check with dryer unit running and no load.)

NOTE: This can be measured with a manometer placed on the exhaust duct approximately two feet (61 cm) from the dryer unit, see illustration below.

MAXIMUM STATIC

IMPORTANT: DO NOT block the airflow at the bottom of the dryer unit’s front panel with laundry, rugs, etc. Blockage will decrease airflow through the dryer unit, thus reducing the efficiency of the dryer unit.

Reduced Clearance Elbow

Installing the dryer unit in shallow closets can be accomplished by using an Elbow, Part No. 62688, which is one inch narrower than a standard venting elbow.
