Drain Water; Electrical Connections; Preparing To Connect The Power Cables; Electrical Installation - Carel humiSonic Manual Del Usuario

Periodical washing is also recommended so as to maintain the WTS that
supplies the humidifi er in good working condition. The water inside the
reverse osmosis system needs to be stirred periodically to avoid excessive
build-up of minerals on the membranes.
Important:
•
do not add disinfectants or anticorrosive compounds to the water, as
these are potential irritants;
•
the use of well water, industrial water or water from cooling circuits
and, in general, any potentially chemically or bacteriologically
contaminated water is prohibited.

3.1 Preparing to connect the power cables

C
1. Unscrew the screw (A) and remove the cover (B);
2.
If the humidifi er is wall-mounted/installed on a horizontal support,
remove the corresponding metal knock-out using cutting nippers on
the bottom/rear panel (C);
3. Fit the cable gland (D).

3.2 Electrical installation

Important:
•
before proceeding with the electrical connections, ensure that the unit
is disconnected from the mains power supply;
•
check that the unit's power supply voltage corresponds to the rated
data shown on the product label;
•
do not power on the unit if tilted or upside down: the transducers may
be damaged.
Connect the power cable to the terminal block through the cable gland.

Note: to avoid unwanted interference, power cables should be kept
separate from probe signal cables.
The humiSonic electronic control board in fact comprises two boards,
a main board (1) installed horizontally, and an auxiliary card (2) installed
vertically.
