Air Filter Cleaning
The COOL CURE 365/ 390/ 395 has one exhaust cooling fan located at the rear panel and
one intake air hole, both equipped with a removable air filter. To remove the air filter, snap
off the flexible plastic fan cover. The air filter is easily removable from the fan opening. Wash
the filter with warm water and air dry. When dry, place the filter inside the plastic cover and
snap shut over fan.
6.1.3
Fuse Replacement
The external fuse is below the power-input receptacle on the rear panel. Remove power cord
and open the small drawer underneath the receptacle. Using a small screwdriver remove
the fuse and replace, then push the drawer shut. Insure that the replacement fuse has the
same rating as the blown fuse.
6.2 Optical Components
The optical components that need maintenance are the heat sink assembly and the light
guide.
6.2.1
Light guides
AUV/LESCO light guides are available in either “liquid-filled” (LF) or “fiber optic” (FO) types.
3.3.2.1.
Liquid-Filled Light guides
The standard light guide shipped with most AUV/LESCO SUPERSPOT cure products is a
1M x 5mm LF model. This device allows flexible delivery of high intensities of energy with
approximately 80% transmission efficiency in the UV “A” and visible ranges. LF light guides
come standard in 1M and 1.5M lengths, in single, bifurcated (dual outputs), and trifurcated (3
outputs) orientations. The light guide tips are available in 3mm, 5mm, or 8mm diameter
models. AUV/LESCO also offers a variety of custom light guides for special purposes.
These include special models optimized for high transmission in the UV “B” and UV “C”
range (230 to 390 nm). Custom lengths are also available upon request. Contact
AUV/LESCO for price and delivery of special products.
AUV/LESCO’s precision-built LF light guides are high quality optical instruments, but their
performance will degrade with exposure to UV energy. Under normal operating conditions,
the user can expect from 1 to 2 years of use from a LF light guide if cared for properly.
However, normal degradation will be greatly accelerated with aggressive radiation and/or
extreme heat levels. For a given dosage, it is well established that higher intensity for
shorter time periods is the preferred method for producing maximum cure strength for the
majority of applications. However, care must be taken to minimize very high intensity levels
for sustained periods of exposure time.
