• A filter box should be installed in front of the heater coil to prevent contamination and decrease in performance (please order separately)
• The PWW heater coils 100-200 are controlled by the temperature regulating system TRW 300 which contains a gate valve 3/4", a thermostate with remote adjustment and a remote sensor (sensor can be used inside the duct or room), the TRW 300 is not included in the delivery and needs to be ordered separately
• The RWHR should be planned in the direction of the flow behind the fan so that the maximum permissible motor temperature is not exceeded because of the transported medium
