Maintenance - Comfort Glow QDE1320 Owner's Manual

Your heater is equipped with a washable filter. For proper operation this filter must be kept clean. If the heater is used
without the filter, dirt and dust can accumulate inside and may cause the unit to smell while in operation and could lead
to operational problems. Use without a filter will void your warranty.
1. WARNING! Make sure the power is turned off before performing any maintenance. Turn off heater, by
using the main power switch on the rear of the unit and unplug the heater from the wall outlet.
2. Remove the filter from the rear of the heater.
3. Vacuuming will generally clean the filter in most cases.
4. If dirt remains, rinse filter with warm tap water through the rear side of the filter (opposite of air intake
direction) until clear of dust and debris.
5. If the filter is extremely dirty or clogged with grease, you can soak the filter in a mild solution of dish soap
and water, and repeat rinsing process.
6. Shake filter to remove excess water and lay on clean cloth or paper towels to dry. Do not use heat source to
dry filter.
7. Replace filter in heater ONLY after it is completely dry.
