Install the temperature sensor in the middle of the cylinder
Ensure the temperature sensor and cylinder make
good contact.
▶ Make sure that the temperature sensor is
positioned correctly in the sensor pocket so that
the temperature will be measured accurately.
▶ Install the installation set [1], temperature sensor NTC of
the accessory [2] and the temperature sensor NTC of the
control unit [3] and position them as shown in Fig. 7.
▶ Push the temperature sensor into the sensor pocket as far
as it will go.
▶ Fasten it using the cable tie supplied.
▶ Secure fastening clip [4].
▶ Connect the terminals of the temperature sensor NTC in
the terminal box to the "NTC TANK" terminals.
