1.11 Water supply connections

Feed water must come to the humidifier from water mains through an intercept tap of a 1/2"
minimum diameter. If more humidifiers are connected to the same mains, the pipe diameter has to
be proportionally increased.
If the water quality is poor, add a secondary mechanical filter to the solenoid one of the machine.
The filters must be regularly cleaned - mainly in, the first working period, and with new plumbing -
. To avoid problems, use the Elsteam flexible piping, supplied with a 3/4" connection already
mounted.
WARNING: Do not feed demineralized water into humidifier!
Supply water need not be potable, but it should not contain physical particles such as sand, mud,
algae, etc. which could interfere with the operation of the water supply valve. If the water supply
system includes a softener composed by resins cartridges, the stainless steel electrodes in the
boiler could be corroded in a short time (if this happens, the boiler will not be covered by the 2
years guarantee).
Water pressure must be kept between 2 and 7 bars. The machine works regularly with feed water
having conductivity between, 800 and 8000 (ohm - cm), but it could also work using water with
different characteristics, giving, however, less performances. With acid water, you should check
for an unusual corrosion, of the electrodes.
If the feed piping is new, before connecting the humidifier solenoid, drain the water for a few
minutes, removing all the waste matter. Intake water temperature must not exceed 50°C.
The electronic controls of the humidifier stop automatically income water in case of leakage inside
the cabinet; however, it will be useful to inspect, every year, all the hydraulic components to avoid
any damage.

1.12 Steam pipe connections

Elsteam humidifiers include a linear stainless steel steam distributor for efficient humidification of
the units inside air and a plastic flange with rubber "o-ring". The steam distributor must be installed
with the steam holes on the top and far from possible obstructions of the air ducts (curves, forks,
changes in piping section size, fans, filters, grids, etc.).
The distance between steam distributor and obstruction has to be kept more than 600 mm in the
direction of airflow.
Steam distributors should not be installed close to cooling batteries or humidity regulation probes
and away from the external air input. Put the distributor in the lowest side of air duct: a minimum
