Valve and Testing
•
To open the valve, push the gas on/off button.
•
Note: The valve can only be opened once the sensors have
stabilised and will also automatically close if the alarm goes
off.
•
To reconnect the gas supply after the alarm has stopped, press
the gas on/off button.
•
The alarm may be tested at any time by pressing the “test”
button. This simulates the presence of gas which should
immediately sound the alarm and close the gas valve.
Sensor Replacement
The gas sensors will lose sensitivity over time. Therefore, it is
recommended to replace the gas sensors every two years. Replacement
sensors available on the Envin Scientific online shop and part numbers are
listed in the Spares section on page 11.
To replace the sensor:
1.
Switch the power off
2.
Remove the top of the sensor housing
3.
Remove the old sensor from the socket
4.
Install the new sensor and push the top of the sensor housing
back on until it clicks shut.
