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 filters, 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 fluid be added to the MLP
RO water tank at an appropriate frequency, but at least once a year.
Nortec Humidity Ltd. recommends using the disinfection fluid SANOSIL S010 AG 5% (our code:
155404000) to the System via the high pressure pump, desired concentration 0.1%. DISIFIN 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 Nortec Humidity distributor
who will be happy to support you.
