Page 12: Commissioning
COMMISSIONING 12.1 The unit operates by extracting warm, stale air from kitchens, toilets / bathrooms, etc, passing it through a heat exchanger and out to atmosphere. A second fan draws in cool fresh air and passes it through the same heat exchanger where it absorbs heat from the outgoing stale air. 12.2 The unit must be set up as detailed in section 10.3, so that the NORMAL setting on the fan speed control enables the INLET fan to deliver the designed volume airflow. -
