Maintenance Guidelines Component
Screen The screen should be free of all debris such as cured material, lint,
dust or anything that might impede cooling or UV transmittance.
Soaking in a compatible solvent to remove any such items may
clean the screen.
as needed
Do not use damaged screens. This can result in RF
leakage.
Reflectors Reflector surfaces should be cleaned every 500 working hours
(more frequently in dirty environments) and at every bulb change.
Clean the reflector surface and cavity with a small amount of
isopropyl alcohol on a lint-free soft cotton cloth, clean room wipes,
or an optical lens cleaning cloth. Do not use paper towels or other
non-optical compatible supplies. Use gentle cleaning pressure.
Use care to protect the edges and corners of the reflectors.
Be careful when replacing reflectors. They are made of glass and
may break if dropped or forced.
as needed
Never use metal polish or any abrasive media to clean the
reflectors.
Pressure Switch
Pressure switches are rated for operation between -40 _ C and
120 _ C. If your system experiences repeated loss of cooling air, the
pressure switch may overheat and fail. Make sure that the
lamphead cooling fan cools the system sufficiently to avoid pressure
switch and other internal lamphead component failures.

enclosure/
lamphead
Filter material is designed to capture dust and contaminants from
the plant before entering the UV equipment. These filters are
located on the lampheads, remote blowers, and some power
supplies (customer-supplied filters). Eventually, the filters will
become loaded with matter and will start to impede the flow of air.
A dirty filter also will release matter into the air stream that may
deposit on the part being cured as well as the bulb and reflector.
Use soap and water to wash all filter material that provides cooling
to any part of your UV system.
