• Use:
The C 1.20 heater may only be operated in conjunction with the
C 1 calorimeter. The C 1.20 heater serves to maintain the correct
temperature of drinking-quality tap water, which must be connec-
ted to the heater at a maximum pressure of 6 bar/0.6 MPa. The
C 1 control connection cable supplied is used to control the C 1
calorimeter.
The conditions for operating the C 1 calorimeter with the C 1.20
heater on a water supply line are:
- tap water: drinking-quality tap water is recommended,
- temperature range: see "Technical data" section; the measuring
mode must be selected according to the water temperature:
water temperature < 21 °C : measuring mode 22 °C,
water temperature > 21 °C : measuring mode 30 °C.
- water pressure: see "Technical data" section (for high or irregular
pressure, we recommend using the C 25 water pressure control val-
ve, available in our accessories range.
Operating mode: tabletop device
Safety instructions
• The C 1 calorimeter's power supply unit must never be positi-
oned beneath the heater or beneath water hoses.
• Connect the C 1.20 heater to the C 1 in accordance with these
operating instructions.
• Use only drinking-quality tap water for operation.
• The permissible operating pressure must not exceed the value
given in the technical data.
• Check the hose system between the devices for tightness be-
fore commissioning.

• Ensure that the hoses and tubes do not slip or bend.
• Regularly check hoses, tubes, and heater for possible material
fatigue (cracks/leakage).
