Maintenance; Care And Cleaning; Replacing The Uv Germicidal Or White Light Tubes - VWR PCR Workstation Instruction Manual

MAINTENANCE

NOTE: Polycarbonate ages 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 warranty.
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
microfibre) 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 polycarbonate
panels!
Due to the specific qualities of polycarbonate panels made of Makrolon
cleaning.
Warning: Unplug the unit before cleaning around the UV tube contacts and internal plug outlets.
Warning: Exposure to UV light is harmful.
The polycarbonate front panel blocks UV not allowing UV radiation to pass through
the panel. The UV lamp will shut off if the front panel is opened. The PCR
Workstation contains a powerful source of UV radiation that will cause damage to
unprotected eyes and skin. Before operating any unit, be sure all personnel in the
area are properly protected. Even though the unit shuts the UV off when the front panel is open, UV
blocking eyewear should be worn as well.

Replacing the UV germicidal or white light tubes

Turn the unit power off and unplug the unit from the power
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 at 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.
We recommend you change the UV tubes after 1000 – 1500
hours of operation.
