3a Mounting of temperature sensor
ON CYLINDER: To ensure accurate control of your cylinder, the temperature
sensor should be mounted on the bottom 1/3 of the cylinder. It is essential that
the sensing element is in direct contact with the cylinder and that there is no
insulation between it and the cylinder. 60°C is the temperature level required in
order to prevent the build up of legionella bacteria. The temperature sensor can
be fixed to the cylinder using the provided foil tape.
