PLEASE NOTE: Vent Fans are suitable for stations not requiring preheated air. It is not Dexon's responsibility to determine if preheated air is required. Dexon will not be liable for any personal injuries, equipment or property damage caused by inappropriate installation and operations

WARNING: If not run continuously Vent Fans may freeze up with frost due to moisture in a wet well when used in cold weather. We therefore recommend that all Vent Fans run continuous to prevent frost build up and also to prevent premature rusting. Failure to do so may void Warranty.
