4.6. Electrical connections
● D isappearance of the causes of the stoppage may pose the risk of danger
during restarting.
● D isconnect the electrical supply to the unit before carrying out any work.
● O nly personnel qualified to perform electrical work may carry out installation
and maintenance work.
Before connecting the unit to the network, ensure that the voltage matches that

An earth connection is compulsory. CIAT shall not be liable for incidents
resulting from faulty or non-existent earthing. Always follow the circuit
diagram delivered with unit.
Circuit diagrams for customer applications should be based on the diagrams supplied:
- Unit wiring for 2-tube systems, without condensate pump (Fig. 10).
- Unit wiring for 4-tube systems, without condensate pump (Fig. 11).
- Unit wiring for 2-tube systems with an electric heater using 2 heating elements,
without condensate pump (P=900 or 1200W max) (Fig. 12).
Note: if necessary, the output of the 300W electric heater can be reduced by
removing the shunt positioned between terminals 8 and 9.
CIAT recommends using a system that controls the unit in relation to the temperature
of the water (to actuate the valve(s) and the use of an electric heater.
All electrical connections are fed into the electrics box marked with the symbol
The electrics box is equipped with a cable grommet to facilitate the routing of the
cables to the terminal block.
● To access the electrical terminal block:
Disconnect the device from the electrical power supply.
