8.4 Dust filter replacement . The dust filters (fig. 3/2) on either end of the UV recircula-
tor with the hidden UV lamp should be checked monthly and cleaned or replaced
when they become clogged. To check, replace or clean the filters, simply unclip the
covers, fit a new filter if necessary or rinse current filters in water, dry and place
back. Clip covers back in place.
8.5 Cleaning and decontamination . Disconnect from the mains before cleaning.
Caution! Do not let liquid get into the control box.
8.5.1 Model UVC/T-AR and shelves P-5 and F-1 , full cleaning. Transparent panels and
shelves are made of acrylic glass (polymethylmethacrylate Altuglas
®
EX) and are
prone to scratches and optical transmission capacity decrease if improperly cleaned.
Use mild soap and water with a soft cloth or sponge for cleaning the panels. Rinse
remaining washing solution with distilled water. Wipe dry the excess water with clean
soft cloth or sponge.
For decontamination, we recommend using a special DNA/RNA removing solution
(e.g. Biosan
PDS-250 ). After washing the inside parts of the box it is necessary to
rub them dry.
Caution! Never use organic solvent based compounds, pure alcohol, alcohol-con-
taining cleaners (more than 20%) or ammonia containing cleaners for
acrylic glass. Do not use abrasives. The table below shows the interaction
of acrylic glass with ethyl alcohol and other solutions.

period and is regarded as normal wear and not covered by the warranty.
Acrylic glass panels can be replaced.
8.5.2 Models UVC/T-M-AR , UVT-B-AR and UVT-S-AR , external cleaning. Glass panels

and water with a soft cloth or sponge for cleaning the panels. Rinse remaining wash-
ing solution with distilled water. Wipe dry the excess water with clean soft cloth or
sponge. Do not use ethanol or other organic solvents.
