2.2 Type of supply water
☺
demineralised water by osmosis;
drinking water ((however more dust in the room
and more frequent maintenance and cleaning the nozzles);
softened water
(the mineral content dissolved in the water is not reduced).

Important: the supply water must comply with the requirements of
UNI 8884 UNI 8884 standard, “Characteristics and treatment of the water
in cooling and humidifi cation circuits”. According to this standard, the
humidifi er must be supplied with water that, as well as being drinkable
(EC directive 98/83), must remain within the following limits:
•
electrical conductivity <100 μS/cm;
•
total hardness <5 °fH (50 ppm CaCO3);
•
6.5 < pH < 8.5;
•
chloride content <20 mg/l;
•
silica content <5 mg/l;
•
conductivity less than 30 μS/cm (it is recommended to use the MC
cabinet in the version for aggressive water).
Similar requirements are also specifi ed in the European reference
standards VDI6022, VDI3803.
Upstream of the cabinet, connect the following to the water line:
•
a water fi lter with a fi lter size no greater than 5 microns (fi lters available
upon request).
•
an expansion vessel (not supplied by Carel SpA) with a capacity of several
litres, to avoid water hammer that may damage the installation.
The water line is tested, and checked at a pressure of 0.35 bars downstream
of the cabinet.

2.4 Type of compressed air
YES
dry and oil-free air
Upstream of the cabinet connect the following devices (available upon
request):
•
a 5 micron fi lter upstream of the cabinet.
•
a fi lter to remove oil and particles upstream of the 5 micron air fi lter
The air line is tested, and checked at a pressure of 2.1 bars downstream
of the cabinet.
2.5 Type of water and air lines
YES
copper pipes (mains drinking water only),
plastic hoses,
polypropylene hoses: ensure faster and simpler connections by
welding.
NO
galvanised steel pipe: may lead to the detachment of impurities,
and cause blocking or damage to the nozzles.
Important: Apply sealant to the joints of the pipes and hoses
running to the atomising nozzles (preferably Tefl on or liquid Tefl on).
