72605794-0 EN 2307 For your safety
2 For your safety
General
Every person working with the Condair ME Control must have read and understood the operation manual
of the Condair ME Control before carrying out any work.
Knowing and understanding the contents of the operation manual is a basic requirement for protecting
the personnel against any kind of danger, to prevent faulty operation, and to operate the unit safely and
correctly.
All ideograms, signs and markings applied to the components of the Condair ME Control must be ob-
served and kept in readable state.
Qualicationofpersonnel
All work described in this operation manual may only be carried out by specialists who are well
trainedandadequatelyqualiedandareauthorizedbythecustomer.
For safety and warranty reasons any action beyond the scope of this manual must only be carried out
by personnel with appropriate industry recognised qualications or training.
It is assumed that all persons working with the Condair ME Control are familiar and comply with the
appropriate local regulations on work safety and the prevention of accidents.
The Condair ME Control may not be used by persons (including children) with reduced physical, sensory
or mental abilities or persons with lacking experience and/or knowledge, unless they are supervised by
a person responsible for their safety or they received instructions on how to operate the system.
Children must be supervised to make sure that they do not play with the Condair ME Control.
Intended use
The Condair ME Control is intended exclusively for airhumidicationandaircoolinginAHU'sor
air ducts within the specied operating conditions. Any other type of application, without the written
consent of the manufacturer, is considered as not conforming with the intended purpose and may lead
to the Condair ME Control becoming dangerous.
Operation of the equipment in the intended manner requires that all the information contained in this
operation manual are observed (in particular the safety instructions).

8For your safety 2605794-0 EN 2307
Danger that may arise from the Condair ME Control
DANGER!
Risk of electric shock!
The Condair ME Control unit (and the optional submerged UV system) contain live mains
voltage. Live parts may be exposed when the control unit (or the terminal box of the optional
submerged UV system) is open. Touching live parts may cause severe injury or danger to life.
Prevention: Before carrying out any work on the Condair ME Control switch off the control unit, dis-
connect it from the mains via the electrical isolator and secure the electrical isolator in "Off" position
against inadvertent power-up.
DANGER!
Health risk because of inadequate hygiene!
Inadequatelyoperatedand/orpoorlymaintainedevaporativehumidication/coolingsystems
may endanger health. When inadequately operated and/or poorly maintained micro-organisms
(including the bacterium which causes Legionnaire’s disease) may grow in the evaporative
module, the water tank and the water system of the Condair ME Control and may affect the air
in the AHU/air duct.
Prevention: the Cond air ME Control must strictly be operated and maintained in accordance with this
manual.
WARNING!
Some types of evaporative material are manufactured from glass bre. Though this material is not clas-
sied as hazardous, it is recommended that Personal Protection Equipment such as gloves, protective
clothing and eye protection are used during handling to protect the user from bres or dust. If dust is
generated during handling it is recommended that respiratory protection is worn.
Correct lifting and handling
Lifting or handling of components always carries an element of risk, and therefore must only be carried
out by trained and qualied personnel. Ensure that any lifting operations have been fully planned and risk
assessed. All equipment should be checked by a skilled and competent health & safety representative.
It is the customer's responsibility to ensure that operators are trained in handling heavy goods and to
enforce the relevant lifting regulations.

92605794-0 EN 2307 For your safety
Preventing unsafe operation
If it is suspected that safe and hygienic operation is no longer possible, then the Condair ME Control
should immediately be shut down and secured against accidental power-up according to Section
4.6. This can be the case under the following circumstances:
– if the Condair ME Control is damaged
– if the Condair ME Control is contaminated
– if the electrical installations are damaged
– if the Condair ME Control is no longer operating correctly
– if connections and/or piping are leaking
All persons working with the Condair ME Control must report any alterations to the system that may
affect safety to the owner without delay.
Prohibitedmodicationstotheunit
Nomodicationsmustbeundertaken on the Condair ME Control without the express written consent
of the manufacturer.
For the replacement of defective components use exclusively original accessories and spare parts
available from your Condair representative.
