Failure to comply can result in explosion or fire. For these applications see PDS CXH-EP (PF305). MAINTENANCE WARNING: Turn off all power to service heater. Do not attempt to service heater while unit is operating as there is hazard of electric shock, injury from operating fan and burns from hot heating elements. 1. Fan motors in these heaters are provided with sealed ball bearings, factory lubricated, requiring no further lubrication under normal service conditions. 2. Following long periods of idleness, heater should be vacuumed before start-up, to remove accumulated combustible particles which otherwise may smoke or incinerate on initial heat up. 3. Periodically inspect all electrical connections and terminals to avoid electrical wiring difficulties. Inspect all wiring for frayed or worn insulation.
