Note
This manual contains all details necessary for the planning and installation of the JS
HumEvap Mobile Humidifier. In addition commissioning, operating and maintenance
details are included.
The manual is intended for use by engineers and properly trained technical
personnel. Maintenance, servicing or repair work must only be carried out by suitably
skilled and qualified personnel, the customer MUST be responsible for ensuring their
suitability.
No liability will attach to JS Humidifiers plc if any damage, injury or accident is
attributable to inattentive, inappropriate, negligent or incorrect installation and
operation of the machinery whether or not caused deliberately.
Always isolate all electrical and water supplies before commencing any maintenance.
Please contact JS Humidifiers plc if in any doubt.
Warning! This Humidifier must be installed, operated and maintained in
accordance with this manual. Failure to do so could result in contamination
that might cause Legionnaires’ disease, which can be fatal.
Your attention is drawn to the Health and Safety Executive's Approved Code of
Practice (ACoP) and their technical guidance on the prevention and control of
legionellosis in water systems. If inadequately maintained, water systems, of which
any humidifier is a part, can support the growth of micro-organisms including the
bacterium that causes Legionnaires' disease. JS Humidifiers plc has considered all
aspects of the design of their humidification systems to reduce as far as possible the
risk of Legionnaires' disease and other similar conditions but it is important that users
are also aware of their responsibilities under the ACoP in reducing the risk of
legionellosis.
To prevent the growth of legionella, users are required to:
Carry out a risk assessment of the water system by a competent
person, and implement a monitoring and control regime.
Avoid water temperatures that favour the growth of legionella
(20-45°C);
Avoid water stagnation;
Clean and disinfect the humidification system in accordance with the
ACoP and enclosed instructions;
NEVER leave your HumEvap Mobile out of operation containing water for more than
24hrs, as it could result in contamination that might cause Legionnaires’ disease,
which can be fatal. In the event that the humidifier is turned off for prolonged periods,
ensure that the water reservoir and pipe-work supplying the unit are drained, unless
they supply other systems which ensure a regular renewal of water in the system. If
the unit is found to have been out of operation for more than 24hrs containing water,
water stagnation and contamination may occur, and the system will require thorough
cleaning.
If you intend to shut the system down for any length of time please contact JS
Humidifiers plc for advice.

consulting JS Humidifiers.
