Manuals” on the TEL UK website: https://tel-uk.com/downloads/ The AFA4000/E airflow controller can be configured to monitor carbon filter saturation using an additional organic vapour type “gas” sensor. For recirculating fume cupboards, hoods and cabinets, the controller can be used to manually adjust the fan speed or can be set to control the fan speed to maintain a face velocity set point for Hepa Filter compensation. -

5. Configuration. Start Up: When the controller is first powered up, the following sequence of event occur: a. If the controller has been calibrated, the controller will run and enter normal operating mode. b. If the controller has not been calibrated, the unit will display “Requires Setup”, Press Mute to continue. - Page 7 Note – Steps 13, Power Up Memory, the controller stores the pushbutton on/off current status and when enabled, will restore the pushbutton to the previous state before powering down, e.g. if the fan was before power down on the controller will power back on with the fan on. Note –...

6.2 Calibration Tips. 1. Allow at least 15 to 20 seconds wait for the airflow to settle before capturing the airflow samples, this will minimize the chance of an error caused by turbulence or fluctuations. 2. Avoid moving in front of the cabinet whilst calibrating the controller. 3.The low and high samples should be at least 0.2m/sec apart to calibrate the controller to ensure the controller is calibrated over a sensible working range. -

Page 16: Installation
Fit the airflow sensor to the side of the cabinet, ensure that the sensor is open to the room. • Connect the airflow and gas sensors. Note – full fitting instructions for the AFA4000 and SM7 airflow sensor are found in the standard AFA4000/E operation manual. Typical Installation. - Page 17 *The sensitivity and response speed of the gas sensor will depend on the sensor location in the plenum. Pre-tested cabinets: for cabinets that have been previously used or have been tested with the gas sensor fitted, ensure the sensor is mounted in the correct location. Un-tested cabinets: for cabinets that have never had a gas sensor fitted, the system will require testing to ensure the sensor detects the filter saturation correctly.
