2. Remove the temperature monitor cable(s).
3. Unscrew the monitor.
4. Refit the cable(s) to the monitor.
5. Dip the monitor sensor in water. Slowly heat the water (about 1° per
minute) using e.g. an immersion heater.
6. Set the control switch to ”ON”. Use a thermometer to check that the
warning lamp lights when the alarm is given at the correct temperature.
Correct temperature is stamped on the monitor’s hexagon.
Tolerance is ± 3° for the monitor.
