CONTROL PRINCIPALS:AC fan will run continuous at full speed
PLEASE BE AWARE: When using the the V04-1, 120VAC, NON IDLING VENT FAN, under certain climatic conditions, the potential exists for freezing and ice build-up in the discharge pipe of the ventilation system of a pump station. The amount of ice build-up may be sufficient to prevent the proper ventilation of the station. For this reason we highly recommend the use of the VO3 HAZLOC VENT FAN, running at a continuous idle speed, where climatic conditions do not necessitate the use of blower heater. The use of vent fans blowing continuous unheated air at FULL SPEED is not
recommended in cold climate areas, and their use will be at the sole risk and responsibility of the owner
