Application/Use
Dulcodes R UV systems serve the purpose of disinfecting and photochemically treating
• drinking water
• service water and
• swimming pool water.
The UV disinfection process involves subjecting the water to be disinfected to short-wave UV light.
This so-called UV-C radiation has a fast and reliable germicidal and sterilising effect.
Chloramines in swimming pool water, for instance, are reliably degraded as part of the photo-
chemical treatment process.
Dulcodes R UV systems feature a manual wiper for the purpose of cleaning the protective tubes
for the UV lamps.
Dulcodes UV systems are turnkey systems ready for connection.
They are available in different versions as defined by the identcode.
The performance data are defined in the datasheet supplied with the Dulcodes UV system.
Scope of delivery
• Radiation chamber
• UV lamps with protective tubes (quantity dependent on type of system)
• UV-C sensor

Safety
2.1
Use for Intended Purpose
• The system serves the sole purpose of treating water.
• The system must only be used corresponding to the technical data and specifications defined
in the operating instructions!
• Any other use or modifications are prohibited.
• Only persons specifically trained and authorised for the purpose are permitted to operate the
system!
• You must observe the information provided in the operating instructions at the various phases
in the life of the system!
2.2
Safety Information
WARNING!
• UV-C radiation is harmful to the eyes and skin!
Place the UV lamps into operation only in their installed state!
Install the UV system in accordance with regulations and instructions before starting up
the UV lamps!
• If not calibrated correctly, a sensor cannot perform its monitoring function.
Under unfavourable circumstances, it is then possible that insufficiently disinfected
water may be fed to the consumer.
• In the case of applications with stringent disinfection requirements (e.g. drinking water
disinfection), disinfect/sterilise the piping system, e.g. in a high-chlorinating process,
prior to initial operation! This is particularly necessary in piping systems that have
already been subject to soiling, germs or micro-organisms.
• Make sure that
- the maximum permissible water flow rate is not exceeded and
- the UV transmission does not drop below the minimum permissible levels
otherwise adequate disinfection can no longer be guaranteed!
• In the event of longer periods of operation of the UV system without flow, particularly in
the case of larger systems, monitor the water temperature and switch off the system or
flush the system to cool it (see “Intermittent Flushing”)!
• The place of installation must be dry and frost-free while ensuring the UV system is
protected from the effects of chemicals, dyeing agents and vapours.
• The ambient temperature and the radiation temperature in the immediate vicinity must
not exceed 40
°
C!
• If the water to be disinfected contains solid particles or turbidity substances, a suitable
filter should be installed upstream of the UV system.
• Make sure that the maximum permissible operating pressure is not exceeded
(see Section 8 “Technical Data”).
• Switch off the master switch or disconnect the power plug before installation and
connecting the UV lamps!
• Do not switch on the system before the radiation chamber is filled with water!
• Make sure that the UV lamps are operated with the standard current!
