the outlet is properly grounded. DO NOT modify the plug provided with this system – if it
does not fit in the outlet, have a proper outlet installed by a qualified electrician.
• DO NOT operate the UV system if it has a damaged cord or plugs, if it is malfunctioning
or if it has been dropped or damaged in any manner.
• DO NOT use this UV system for other than intended use (potable water applications). The
use of attachments not recommended or sold by the manufacturer/distributor may cause
an unsafe condition.
• DO NOT store this UV system where it will be exposed to temperatures below freezing
unless all water has been drained from it and the water supply has been disconnected.
WARNING
• Acuva is not liable for consequential or incidental damages due to improper installation.
• This system contains a UV-LED. Do not operate the device when water is not flowing in
the chamber.
