2.2 Health & Hygiene
DANGER!
Risk of infection or serious illness
The Condair ML System 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.
DANGER!
Risk of water contamination
To prevent water stagnation and microbial contamination, the systems power supply should be left
switched on. If the system is switched off for more than 48 hours, the pipework and system must be
disinfected as per the instructions, and a full risk assessment must be undertaken to ensure safe
operation.
Health Risks
Please observe the local health and safety codes, standards and technical guidance on the control of
Legionella in water systems.
The user is responsible for ensuring that the water system complies with local regulations, bye-laws and
guidelines (such as the HSE ACoP L8, VDI 6022, ISO 22000, HACCP or equivalent). If inadequately
maintained, water systems, of which any humidier is a part, can support the growth of microorganisms,
including the bacterium that causes Legionnaires’ disease.
Condair ML systems, products and components are produced according to the ISO 22000 standards,
which means that we have considered all aspects of this equipment to reduce the risk of Legionnaires’
disease and other similar conditions. However, the user is responsible for ensuring that the installation,
operation and maintenance work on the equipment is performed in a manner ensuring that the system
stays clean.
Any risks or hazards relating to the system, including during installation and maintenance, should be
identied by a competent health and safety representative who is responsible for introducing effective
control measures.
Water monitoring
The quality of water being used in the Condair ML Humidication System should be checked prior to
system commissioning and comply with the guidelines in the high pressure pump manual.
The Condair ML Humidication System must be monitored for hygiene as part of the maintenance pro-
gram. Please refer to the maintenance section for further guidance.

9For Your Safety
Condair MLP XXXXXXX_EN_1905
Guidelines for a Hygienic System
• Carry out a risk assessment of the water system using a competent person, and implement an ap-
propriate monitoring and control program.
• Initiate procedures for changing lters, disinfection etc.
• Enter into a service contract that suits your company.
• Stop the system if polluted drinking water is found in your area.
• Avoid water temperatures between 77 °F (25°C) and 113 °F (45°C), which favour the growth of
Legionella.
• Do not stop the system unless it is faulty or leaking (avoid water stagnation).
• Refrain from closing nozzles or sections, unless there is leakage or a fault (avoid water stagnation).
• Disinfect the high-pressure system at least once a year and after every maintenance or repair. Always
carry out a complete system disinfection if it has been turned off for more than 48 hours.
• Have water samples taken and tested for harmful bacteria at least once a year.
• Conduct follow-up measurements until the system is clean if bacteria have been detected in the system.
Disinfection
Depending on the system hygiene, it is advised that preventative disinfection uid be added to the ex-
ternal RO water tank at an appropriate frequency, but at least once a year.
Condair Ltd. recommends using the disinfection uid HaloSpray or Sanosil S010 AG 5% (part number:
155404000) to the System via the high pressure pump, desired concentration 0.1%. HaloSpray or Sanosil
is safe, non-toxic and eco-friendly which provides a prophylactic, disinfection dose and is effective against
all types of microorganisms, including Legionella and E.coli.
Please read the pump manual for more information on disinfection.
If you are in any doubt about the suitability of water quality, please contact your Condair distributor who
will be happy to support you.
