Check whether the condensate pan is completely emptied by Condensate drain Ø16 mm partly filling it. NOTE SCHAKO recommends installing vibration-damping fixing elements to avoid structure-borne noise transmission. NOTE The rods, screws or vibration damping fixing elements required for installation are not included in the delivery.
If no differential pressure gauge is available, the filter should be replaced when it is full (dark filter mat). SCHAKO recommends purchasing replacement filters to avoid prolonged downtimes during maintenance activities.
