Ensure that the same Gas Type and Range of Sensor is fitted in place of the old Sensor.
Care should be taken when removing and refitting the Sensepoint XCD plug-in Sensor
Cartridge to the Sensor Socket so that damage to the connection pins can be avoided.
The sensor head must be fitted with the supplied weather protection, and mounted so that
