Untrained personnel can perform basic maintenance such as
cleaning and replacing filters. All other operations should be per-
formed by trained service personnel. When working on heating
equipment, observe precautions in the literature, on tags, and on
labels attached to the unit. Follow all safety codes. Wear safety
glasses and work gloves. Have a fire extinguisher available.
Recognize safety information.
