Table 5-1 lists typical maintenance guidelines and replacement schedules
for the components of the CW2 410 lamphead.

and reflectors and cleaning or replacing filter material. It is also
recommended that reflectors be cleaned periodically.

UV Bulb Bulbs are warranted for a specific number of hours when operating
under manufacturer operation specifications (hours vary with
differing bulbs). Depending on your application, some installations
may provide acceptable curing well beyond the warranty.
NOTE: Do not touch or handle the bulb with bare hands. Be sure to
clean them with a lint-free cloth or tissue to remove any fingerprints
that might be present.
as needed
Magnetrons The magnetrons are warranted for a specific number of hours when
operating under the manufacturer operation specifications. Each
application will be different and, in many cases, the magnetron life
will last well beyond the warranty.

hours of
operation
or as needed
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
radiation leakage.
Reflectors Reflector surfaces should be cleaned every 500 working hours
(more frequently in dirty environments) and at every bulb change.
Wipe the reflector surface and the cavity with a clean, lint-free cloth
dipped in a suitable solvent such as isopropyl alcohol.
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.

lamphead
Filters are designed to prevent dust and contaminants from entering
the UV equipment. In some applications these filters are located on
the lampheads, remote blowers, and some power supplies.
Eventually, the filters become loaded with matter and start to
impede the cooling air flow, causing excessive heat which will result
in premature failure of the UV equipment. A dirty filter can also
release matter into the air flow that may deposit on the part being
cured as well as the bulb and reflector.
Clean filters as needed.
Weekly
or as needed
NOTE: Nordson does not supply filters on the power supply, the lamphead, or external blowers. Filters
must be supplied by the customer. Internal blower lamphead filter is provided.
