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.
ON PIPEWORK:
To ensure accurate control, the temperature sensor should be
mounted on the pipework as tightly as possible. It is essential that the sensing
element is in direct contact with the pipework and that there is no insulation
between it and the pipework. The temperature sensor can be fixed to the
pipework using the provided foil tape.
