Maintenance and Repair
WARNING: Allow only qualified personnel
to perform the following tasks. Follow the
safety instructions in this document and all
other related documentation.
Maintenance and
Replacement Schedule
Recommended maintenance to the power supply
consists of cleaning or changing the cooling fan
filter material, if present, and removing dust from
the power supply.
Establish acceptable curing levels for your process
and then develop a maintenance schedule that fits
your needs. Radiometers can be used to measure
relative readings for spectral output as a means of
monitoring spectral intensity.
The maintenance and replacement schedule for
the system will depend upon your:
S
application process
S
plant environment
S
quality of cooling air passing through the
system
S
coating formulation

Filters
Remote blower
cooling fan
electrical
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.
Weekly
or as needed
NOTE: Dirty filters can cause excessive heat, which will cause premature failure.
