MPORTANT
This manual should be read thoroughly before specifying, designing, installing or operating
a Devatec ElectroVap RTH system. Please retain for reference and should you have any
question, please contact one of our authorized dealers.
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 RTH generates steam during operation and
therefore, surfaces and pipe-work become very hot. Ensure that equipment not sustaining
high temperare be kept away.
Take care : the end user should ensure that the equipment be disposed of according to the
prevailing regulations.
DELIVERY & 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 the authorized dealer.
It is recommended that the ElectroVap RTH 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 co-
ver and protected from physical damage, dust, frost, rain and humidity. More than 6 months storage is not re-
commended.

Safety information
IMPORTANT
This section should be read carefully to ensure the safe and correct installation of your humidifier.
GENERAL
This manual contains all details necessary for the planning and installation of the ElectroVap RTH humidifier.
In addition commissioning and maintenance details are included.
The manual is intended for use by engineers and properly trained technical personnel. Maintenance, servic-
ing or repair work must only be carried out by suitable skilled and qualified personnel, the customer must be
responsible for ensuring their suitability.
Any risks or hazards, especially when working from ladders or towers should be identified by a skilled and
Health and Safety representative and effective control measure put in place.
No liability will attach to the Distributor if any damage, injury or accident is attributable to inattentive, inappro-
priate, negligent or incorrect operation of the machinery whether or not caused deliberately. Always isolate
all electrical and water supplied before commencing any maintenance.
Every effort has been made to ensure details contained in this manual are correct, however, in view of the
wide range of conditions experienced in air handling systems, the information provided should only be used
as a guide. Please contact your Agent if any doubt.
CORRECT USE
ElectroVap RTH humidifiers are ONLY intended for use with air handling systems or direct air humidification.
ANY OTHER APPLICATION IS NOT CONSIDERED USE FOR THE INTENDED PURPOSE. THE MANU-
FACTURER CANNOT BE MADE LIABLE FOR ANY DAMAGE RESULTING FROM INCORRECT USE.
WATER
ElectroVap RTH humidifiers are designed to be used with mains, demineralized R/O (minimum 30 μs) or
softened water. On no account attempt to introduce any other fluid or chemical into the system. Water sup-
ply should not exceed 6.0 bar and installation should comply with local regulations.
ELECTRICITY
All work concerned with electrical installation MUST only be performed by skilled and qualified technical per-
sonnel (eg electrician or technicians with appropriate training). The customer MUST be responsible for en-
suring their suitability.
It is the duty of the installer to ensure that suitable sized cables and MCB protection is provided. Please ob-
serve the local regulations concerning the provision of electrical installations. The humidifier MUST be con-
nected to earth.
WARRANTY
A warranty term is applicable to the parts of the RTH humidifier to the exception of the valves and the heating
elements provided our recommendations of use & maintenance have been adhered to. Failure to specify and
fit original parts and accessories will invalidate our warranty.
NOTE
Our policy is one of continuous research and development. We therefore reserve the right to amend without
notice the specifications given in this document.

x Unpack the unit and check for any damage.
x Damage to packing and/or unit must be reported by registe-
red letter to carrier within 3 working days.
x Provide free space all around the unit : 1 m. to 1.20 m (3.3 to
4 ft) from the floor, 1.25 m. (4.1 ft) ahead and 0.60 m. (2 ft) on
the right hand side for allowing easy access for maintenance.
x Mark the mounting holes and drill. Insert pegs appropriate for
support.
x Screw the upper screws allowing about 10 mm (0.4") for han-
ging the cabinet. Hang the cabinet and screw the lower
screws. Thighten up all the screws for securing the installa-
tion.

A fresh mains cold water service should be used to supply the
unit. The water pressure should be between 1 and 6 bars (15
to 90 psi) & should not exceed 40°C (104°F) in temperature.
The water supply connection is under bottom of the unit. The
humidifier is delivered with a water inlet hose of 50 cm (20") long
with a 3/4" female fitting to the cold water supply. A direct
copper connection is PROHIBITED.
A check valve should be located on the mains and cold wa-
ter service connection to the unit.
The inlet valve base has a basket filter (s.a. page 38).
The RTH humidifier uses water to produce steam so lea-
kage may happen causing potential damage. If an installa-
tion in false ceiling or above prime rooms (such as mu-
seum, exhibition or laboratory rooms) is considered, ensure
that the floor below the humidifier is constructed from wa-
terproof materials (with draining facilities) to withstand any
water spilling during servicing or if a problem occurs.
Information about the water quality : Chloride concentration :
< 75 mg/l ; phosphate concentration : < 5 mg/l ; chlorine concen-
tration (3 to 6° dA) : < 100 mg/l ; poor concentration in CO2 ;
organic elements in poor concentration.
The RTH humidifier can run with the following water qualities :
x Tap or raw water : water TH between 5°and 40° French
grade
x Demineralized water : 30 μS minimum (caution : the de-
mineralized water is corrosive ; use appropriate piping
material : stainless steel, PVC)
x Softened water (TH 0° not recommended) : the cation exchangers (softeners) do not suit for the water
supply as they do not bring down the mineral salt content disolved in the water., the polyphosphate mea-
suring devices as well.
A water softener consists basically in replacing a calcium ion by a sodium ion the solubility capability of which is
about 7 times higher. So a water softener does not affect the quantity of mineral salts contained in the water but
alters their nature.
An excess of sodium chloride may generate foam which disturbs greatly the correct running of the humidifier. It
is essential that a duplex softener be used.
A small volume of tap water must be added to the softened water to get a TH value of 10° minimum and a wa-
ter analysis is recommended to determine the sodium chloride content.
