Water Monitoring
The
HE2
water system must be must be monitored for hygiene as part of the maintenance programme. Please
refer to the maintenance section for further guidance.
Disinfection Tablets
Depending on the system hygiene, it is advised that preventative disinfection tablets should be added to the
HE2
water tank at an appropriate frequency, such as a monthly basis.
Condair Ltd.
recommend adding disinfection tablets (our code DISIFIN XL) to the tank at approx 500 ppm
strength on a monthly basis to control microbiological activity. DISIFIN is a safe, non toxic, environmental
friendly & 100% biodegradable chemical which provides a prophylactic, disinfection dose and is effective
against all types of microorganisms including; legionella and E.coli.
DISIFIN may be added to the tank whilst the system continues operating and left to dissolve away naturally.
Please refer to the maintenance section for further guidance.
Note: Adding DISIFIN tablets or other disinfection chemicals will increase the conductivity in the tank. This
should be taken into account on systems where a conductivity control system is in use.
If you are in any doubt about the suitability of water quality please contact your
Condair distributor who will be
pleased to support you.
