Introduction; Operating Stages - Carel compactSteam Mode D'emploi

Range of isothermal humidifiers for steam production in rooms.
The steam is produced from the water contained in the cylinder
(connected to the mains). The water boils and evaporates due to
the electric current generated by two immersed electrodes in the
cylinder.

1.1 Operating stages

• the humidifier opens the fill valve (1) connected to the main
water supply;
• the water flows through the hose (2) to the tank (3), the flow
restrictor (4) controls the filling speed;
• when the tank is full, the water overflows into the hose (6) and
starts filling the cylinder (5);
• once the level of water in the cylinder has been reached, the
humidifier closes the fill valve (1);
• the current generated by the immersed electrodes in the
cylinder (7) heats the water until it boils;
• the steam exits the cylinder through the outlet (8) and -
depending on the model of humidifier - is distributed directly
into the room (using a fan), or into the duct (via a steam line).
Note:
• if the water in the cylinder exceeds the level sensor (9), the
humidifier will activate the drain pump (11) and empty the
excess quantity;
• if the current generated in the cylinder exceeds the required
level, the humidifier will activate the drain pump (11) and
discharge the amount of water needed to restore the correct
current;
• before emptying the humidifier activates the tempering valve
(10) to cool the water to 60°C/140°F;
• the humidifier automatically controls the quantity of mineral
salts dissolved in the water by activating the fill (1) and drain
(11) pumps;
• the cylinder is fitted with a filter (12) to prevent the mineral
debris from blocking the drain pump (11);
• if the humidifier is in standby and does not produce steam
for more than 3 days (72 hours), the water in the cylinder is
automatically emptied;
• the fill tank (3) is connected to an overflow hose (13) to prevent
contact between the mains water and the water in the cylinder;
• the current running through the cylinder is controlled by the
current transformer connected to the electrodes (7).
