Information

The MBE AFP heater can be used very simply to reheat the incoming fresh air. If setting the outlet temperature with the internal potentiometer is not sufficient, a room wall thermostat with an expansion contact can be used, which will block the heater operation when the room temperature is reached. If the room temperature drops, the thermostat will unlock the heater operation.

Warning

A minimum of 0.5 m of steel pipe must be installed in front of and behind the heater to prevent contact with combustible parts. The use of an air flow sensor or pressure sensor is required to block the operation of the heater if the flow rate or flow velocity falls below the permitted limit.

When shutting down the HVAC system, the fan must be allowed to run for a minimum of 2 min to cool the heating rods.
Otherwise, damage to the heater and other equipment may occur.
