ROUTINE INSPECTION AND MAINTENANCE
ISOLATE THE UNIT FROM THE POWER SUPPLY AND ENSURE THAT IT CANNOT BE ACCIDENTALLY SWITCHED BACK ON
1. At intervals appropriate to the installation, the fan should be inspected and cleaned to ensure there is no build up
of dirt or other deposits on the impeller or the motor (Caution – do not dislodge any balance weights which may
be fitted to the impeller). If the fan is handling dust laden air, it is recommended that a filter is installed.
2. All Vent-Axia acoustic fan motors are fitted with sealed for life bearings and do not require lubrication.
OVERHEATING PROTECTION
The fan motor is fitted with Standard Thermal Overload Protection. This will automatically switch the fan Off in the
event of a fault condition. If this occurs, isolate the fan, check for any obstruction, leave the fan for a short time for
the motor to cool before reconnecting the power supply. If the fault reoccurs, isolate the power supply and call a
service engineer.
