Installationtips:
The humidifier should be operated within 5°C and 40°C in a room with less than 80% of
humidity.
When in operation, the rear panel becomes hot (60°C) so do not hang the humidifier on a heat
sensitive surface.
The devatec humidifiers have been developped to be hanged on wall. Before installation,
make sure that the surface material is strong enough to hold the humidifier.
The best performances of the humidifier are achieved when the steam discharge is made at
short distance from the humidifier (see after page n°20).
Consider free space around the humidifier to allow easy access for maintenance purposes
(s.a. here under sketches).

ELECTROVAP MC2
Installation - Step 2
Recommendations:
The operating principle of the electrode steam humidifier is the electrolyse
where an electrical current runs through stainless steel electrode plates
immersed in water made conductive by the mineral salts it contains.
The ElectroVap humidifier can produce steam from 3 water qualities having
the following characteristics :
Town water or raw water : the water TH should be between 0 and 40°
French grade for a conductivity between 350µS and 1000µS/cm (Micro
Siemens per centimetre).
Softened water: water treated by sodium/calcium permutation on resins.
The titration value TH should be kept as constant as possible and between
0° and 2°.
It is essential that the salt maintenance of softeners be programmed for the
water volume consummed in order to prevent an excessive salt
concentration to humidifer once the regeneration cycle is finished (please
refer to the softener’s user manual). Duplex softeners are best suited to
your humidifier in this regard. In doubt, please consult devatec.
Demineralised water: this is a water treatment by reverse osmosis or
running through resins.
The ElectroVap humidifier can work with demineralised waters having a
minimum water quality of 30µS/cm. A tea spoon of bicarbonate of soda
must be added on start-up to initiate steam production.
Nota Bene : on starting up the humidifier, the nominal steam production is
reached after one or two days when using low conductivity waters.
This period can be shortened by adding a tea spoon of salt that has been
firstly diluted in 1/4 litre of water. Pour the mixture into the filling cup.
Caution : do not touch the water - Risk of electric shock.
THIS MUST BE CARRIED OUT BY A SKILLED AND QUALIFIED
PERSONNEL.
No chemical agent whatsoever (chlorine, disinfectant, ozone… ) must
be added to the water. Some water qualities may generate foam that
can disturb the correct functionning of the humidifier. If this occurs to
your humidifier, please refer to devatec for further assistance.
WATERCONNECTION
Recommendationsonwatertapping:
A fresh mains cold water service should be used to supply the unit. The
water pressure should not exceed 6 bar and should not be inferior to 1 bar
with a temperature less than 40°C. In case the water pressure exceeds 6
bar, a water regulator valve must be used.
The water supply connection is on the bottom of the unit. All the ELMC are
supplied with a 500 mm long water inlet hose with a 3/4” female
connection to the cold water supply. A check valve should be located on
the mains and cold water service connection to the unit.
The ELMC humidifier uses water to produce steam so leakage may
happen causing potential damage. If an installation in false ceiling or
above prime rooms such as museum, exhibition or laboratory rooms
is considered, ensure that the floor below the humidifier is
constructed from waterproof materials (with draining facilities) to
withstand any water spilling during servicing or if a problem occurs.
b a
The water level must be
between « a » and « b » for
the maximum capacity of
the cylinder.

Evaporationdistanceorvaportrail«D»
A certain length is required so that the steam coming out of the steam distribution pipe be
absorbed by the air. All along this length, descrided as the evaporation distance, the steam can still
be seen in the airflow as a mist which can condensate in water against any obstacle if placed within.
To prevent condensation, this evaporation distance should be calculated before positioning the
steam distribution pipe.
Howtocalculatetheevaporationdistance«D»
In order to determine the evaporation distance, the attached calculation table can be used :
HR1 = relative humidity of air before humidification in %.
HR2 = relative humidity of air after humidification in %.

1. We would recommend to use the steam hose from Devatec supply .
NB : when the humidifier is started up for the first time, a smell of burning may be smelt
especially when brand new hoses are installed. This is normal and will eventually dispel.
2. Steam hose selection :
• SM CYL = small cylinder, LG CYL = large cylinder
3. The ELMC humidifier can be used with pressure ducts (P) having the following characteristics :
If P is inferior to 150mm CE (Water column) i.e. 1470Pa.
If P is between 150mm CE et 300mm CE, our optional filling cup plateform must be
used
4. Please adhere to the recommendations given underneath for the installation of the steam hose
according to one of the shown examples, the most suited to your installation. A set of hose
clamps are supplied for ensuring a correct installation.
The humidifier should be located within 3 m. of the steam distribution pipe. If the distance is
superior to 3 m., insulated steel or copper pipe of a slightly larger diameter must be used.
