(See technical notice page n°31)
All works concerned with electrical installation must be carried out by a skilled and qualified
personnel.
Make sure that all incoming power supplies are isolated before installation and maintenance of
the ElectroVap RTH humidifier.
1 - Power supply isolator and MCB ( near the unit )
2 - Power supply cable
3 - Electrical compartment
WARNING :
Failure to fit an electrical power isolator and MCB as part of
the electrical installation signif icantly increases the risk of
electric shock, which can be f atal.
Q1 and Q2: MCB and electrical power isolation
The symbol
∆
between Q1 & Q2 means that these
MCB are coupled. The power MCB Q2 and control
MCB Q1 are mechanically linked together. So if a
fault is detected, the power and the control circuits
are switched off and there is no voltage on the unit.
The unit is really off voltage.

Install a differential electrical circuit breaker in head of the line supplying the humidifiers inside the general swichboard.
In case of several humidif iers, we would recommend to install a differential circuit breaker per humidif ier so as to
prev ent a total power cut off of all the humidif iers.
