"humiFog direct" +0300073EN rel. 1.4 - 29.03.2022
4.2.2 Feedwater characteristics
humiFog Direct requires demineralised water, so as to ensure:
•
minimum maintenance;
•
no blockages of the nozzles;
•
no dust (the droplets that evaporate will not leave mineral salts in the
environment);
•
improved hygiene.
The use of demineralised water is also required to comply with standards
UNI8883, VDI6022 and VDI3803.
humiFog Direct must only operate on demineralised water that falls
within the limits listed in the following table. Normally, these values can
be obtained by reverse osmosis or nanofi ltration of the feedwater.
Ion exchange softening is not recommended, as it is ineff ective in
removing salts and as it can cause microbial contamination.
Temperature 5 ÷20°C (41÷68°F)
Specifi c conductivity 25 ÷ 80 μS/cm
ph 5.5 – 8.5
Total hardness (TH) 0 ÷ 25 mg/l CaCO3
Temporary hardness 0 ÷ 15 mg/l CaCO3
Chlorides (Cl) 0 ÷ 10 ppm Cl
Iron + manganese (Fe + Mn) 0 mg/l
Silicon dioxide (SiO2) 0 ÷ 1 mg/l
Chlorine ions (Cl-) 0 mg/l
Calcium sulphate (CaSO4) 0 ÷ 5 mg/l
With regard to microbiological parameters, the water used must be
of drinking quality. If it is not possible to keep the water temperature
below 20°C (68°F), appropriate measures must be provided for in the risk
assessment document by the person in charge of running the system.
4.2.3 Cabinet drain connection
The drain point located at the bottom of the cabinet must be connected
externally (3/4" GAS F fi tting) to an open discharge with drain trap.

Also remember that the cabinet cannot be installed on the fl oor without
a support that keeps the cabinet raised by at least 20-30 cm.
NO TI C E:
the drain water must be able to fl ow freely.
4.2.4 Blower water supply line
With reference to the high-pressure hoses provided by CAREL (inside
diameter Ø = 6.3 mm), in order to ensure correct operation of the
atomisation system, the water supply line to the blowers in a single zone
must respect the following maximum lengths:
Model Rated pump

4.3 Electrical installation
WARNING: electric shock hazard.
Dangerous electrical voltage.
Before making the electrical connections, the appliance must be
disconnected from the mains and secured against restarting. Electrical
disconnection must be ensured by means of a measurement.
The user is responsible for connecting the pumping station to the power
supply.
230 V 50 Hz for CE version UA***DD*01
120 V 60 Hz for UL version UA***DU*01
The connection must be made in accordance with local regulations,
using a suitable cable cross-section. A three-core cable (phase + neutral
+ earth) must be connected to the three terminals (L + N + GR).

L L / F (line)
N N / W (neutral)
GR GR / PE (earth)
Important: fi t an external power switch on the humidifi er power supply
line to isolate the power supply, and a TT earthing system with earth fault
current of 30 mA.
No additional wiring is required to the cabinet terminal block, except
for the power supply to the blower fans, using the terminals. For the
electrical connections from the cabinet to the blowers, see par. "Blower
unit electrical connection".
