Safety information
IMPORTANT
Please read, heed and follow the enclosed safety information and
the warning labels inside the humidifier before installation or
maintenance.
Warnings & safety symbols
Warning : This symbol is used to designate a danger of injury or
potential damage to the system.
Caution : High voltages are present inside the humidifier. All works
concerned with the electrical installation must be carried out by skilled
and qualified personnel.
Caution : Danger of scalding ! The ElectroVap KIT MC generates
steam during operation and therefore surfaces and pipe-work become
very hot. Ensure that equipment not sustaining high temperatures be
kept away.
Warning : the end user should ensure that the equipment be disposed
of according to the local prevailing regulations.
Delivery and storage
Any loss or damage during delivery should be reported to carrier by
registered letter within 3 working days and be advised to devatec or to
authorized dealer.
It is recommended that the ElectroVap KIT MC humidifier be kept in its
transit packaging for as long as possible prior to maintenance. If the
humidifier is to be put into storage prior to installation, it must be stored
under cover and protected from physical damage, dust, frost, rain and
humidity. More than 6 months storage is not recommended.

ELECTROVAP KIT MC
Installation - Step 1
 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.
 Consider free space around the humidifier to allow easy access for maintenance purposes

Method :
ELECTROVAP KIT MC
Installation - Step 1
Pick up the supplied drilling template and lay it
flat against the wall where the humidifier
should be installed paying care of the
measures.
The small KIT MC 5 to 30 requires 8 drilling
marks while the large KIT MC 40 to 60
requires 16 drilling marks. For the large kit,
mark the first eight drilling marks, trace the
template corners and then report the drilling
template to the right side aligning the corners.
Mark the eight drilling marks anew.
Drill holes at the drilling marks, insert pegs
appropriate to the support.
Any loss or damage during delivery should be reported to carrier by registered letter within 3
working days and be advised to devatec or to authorized dealer.
Unpack the humidifier from its carton box, take the steam cylinder off the bracket and lay it gen-
tly on ground and attach the humidifier bracket on the the wall as per the following :procedure :
Take the upper bracket and fix it with a screw
(as per in 1 on the attached drawing). Level
the bracket with a bubble level and screw up
the other three screws.
Take care : KIT MC 40 to 60 requires that two
upper brackets be wall installed and secured
by 8 screws.
Take the lower bracket, install it on wall with
screws 2 & 3 as per attached drawing. Control
vertical alignment and distance H (s.a. pages
12-13) and screw up the 4 screws.
Take care : KIT MC 40 to 60 requires that two
lower brackets be wall installed and secured
by 8 screws.

ELECTROVAP KIT MC
Installation - Step 1
Pick up the cylinder, tilt it a little to
engage the steam outlet inside the
retaining spring.
Lift the cylinder upward, put the drain
outlet facing the drain valve body and
push downward to fit it into it.
For KIT MC 40 to 60, install the
second cylinder the same way.
Make sure that the retaining spring
fits correctly the top of the cylinder.
For KIT MC 40 to 60, attach the
second retaining spring the same
way.
The Installation step is now over.
The unit should now be properly connected to mains, water supply and to steam dis-
charge.

15
ELECTROVAP KIT MC
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 1000µ and 350µS/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.
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.
WATER CONNECTION
Recommendations on water tapping :
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.
The water supply connection is on the bottom of the unit. All the KIT MC
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 KIT MC 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.

16
ELECTROVAP KIT MC
Installation - Step 2
Steam ouput
The connection to the steam outlet should be made with a Ø 25 or 40 mm steam
hose as per the model of humidifier. To prevent steam leakage, it must be tightened
with the supplied clamp.
A Ø 25 mm heat resisting drain hose must be connected to the drain outlet. To prevent
any water leakage, the drain hose must be tightened with a collar clamp.
For an easy installation, a water hose kit (part nb 10005902) is available (s.a. page 8) .

ELECTROVAP KIT MC
Installation - Step 3
RECOMMANDATIONS :
All works concerned with the electrical installation must be carried out by
skilled and qualified personnel (eg electrician with appropriate training).
The customer is responsible for ensuring their suitability. Please observe
local regulations concerning the provision of electrical installations.
Check all electrical terminal screws at commissioning, after 50 hours
operation and at every service thereafter.
Take care : the KIT MC electronic components are very sensitive to
electrostatic shocks. Appropriate steps must be taken before any
operation.
