PROCEDURE 5—KEEPING FILTERS CLEAN
WARNING: Never operate unit without a filter or with filter access door removed. Failure to adhere to this warning
could lead to a hazardous condition which could lead to equipment damage and bodily harm.
As a homeowner, keeping filters clean is your most important responsibility. A dirty filter reduces efficiency of your system, causes erratic
performance of controls, and could result in damage to motor or heating equipment.
1. Inspect filters at regular intervals depending on dirt conditions. For new homes, check filters every week for 4 consecutive weeks. In all
cases, inspect filters at least every 3 to 4 weeks when system is in constant operation. Replace or clean filter at least at beginning of each
season (heating or cooling) and thereafter as needed.
2. If the permanent filter supplied with filter rack becomes dirty, it can be cleaned with cold water and soap.
Be sure that filter is thoroughly dry before installing back into furnace.
