What You’ll Need to Install a Chevron LEV Indicator
The Chevron LEV indicator comes with all of the parts required to attach it to your system.
In order to install a Chevron LEV indicator, you’ll need:
- A drill with drill bit (6mm)
- The LEV indicator & tubing that come with the indicator
The installation process is as follows:
- Attach the strapping. This will attach the monitor to the ducting
- Thread the strapping through the indicator & into the tab that tightens the strap
- Put the monitor into position & tighten the strap. If you have a pre-drilled hole, put the rubber plug provided into the hole & attach the tube to the rubber plug & the monitor
- Run the system & use the magnet to calibrate. Simply hold the magnet to the right of the LED hole, approximately 10mm to the right of the LED, until the LED illuminates continuously. When this happens, move the magnet away from the Chevron and wait until the LED starts to flash. Once more, hold the magnet in the above position until the LED illuminates continuously. Now take the magnet away again.
The monitor can be installed both on a suitable surface or on the duct. You can also use alternative methods like banding, self-tapping screws, nuts, and bolts.
What Does a Chevron LEV Indicator Display?
The display will show you an arrow if the system is working. If things aren’t working as expected, the system will display an X.
Before installing the indicator, you will need to know that the duct you are connecting the LEV monitor to has sufficient airflow to ensure the system is working correctly. This information is usually provided within your LEV report or by the LEV Engineer at the time of testing.
What is a Chevron LEV Indicator?
An LEV Chevron Monitor is visual LEV indicator. The Health & Safety Executive recommends fitting indicators to all Industrial Ventilation & LEV systems. The Chevron Monitor will give a visual representation of the direction of airflow as well as whether the airflow is sufficient.
