MAINTENANCE

NOTE: Polycarbonate is aging in UV light, therefore crazing is considered as a normal process.
Crazing will occur with time. Reduce crazing by keeping exposure to UV to a minimum. Crazing
may occur within the warranty period and is regarded as normal wear and not covered by the war-
ranty. Polycarbonate panels can be replaced.

Care and cleaning

The front and side panels are made of polycarbonate and are subject to scuffing and scratches if
improperly cleaned. Therefore it is strongly recommended to use a soft cloth (preferentially microfi-
ber) for cleaning.
Wipe excess water from inside the unit and outside the unit with an absorbent soft cloth or
•
sponge.
Use mild detergent and water with a soft cloth or sponge to clean the exterior and interior of the
•
unit.
Clean the front and side panels with a mild detergent only.
•
Do not use abrasive pads or cleansers.
•
A plastic cleaner solution is recommended to clean the front panel and is available from local
•
plastic supply distributors.
Never use organic based compounds like acetone or ammonia containing cleaners for polycarbon-
ate panels!
Due to the specific qualities of polycarbonate panels made of Makrolon
for cleaning.
All metal parts consist of stainless steel V2A. Stainless steels have sufficient corrosion protection
against normal environmental influences. It is strongly recommend to use a stainless steel cleaning
and care spray. This cleans not only, but also leaves a protective layer. Do not use aggressive
cleaning agents.
Warning: Unplug the unit before cleaning around the UV tube contacts and internal plug outlets.

Replacing the UV germicidal or white light tubes

Turn the unit power off and unplug the unit from the outlet. Lift
up the front panel and locate the tubes. The tube has two
prongs on each end that first fit into a socket, then rotate into
place.
Carefully hold the tube on the end and insert the tube into the
socket. Twist the tube 90° until the tube locks into place.
Drawing shows tube location in top assembly. Outer tubes are
the shortwave 254 nm UV and the middle tube is white light.
