9 MAINTENANCE AND SERVICE
9.1 Camera and Lens Cleaning
9.1.1 Camera Body, Cables and Accessories
The camera body, cables and accessories may be cleaned by wiping with a soft cloth. To
remove stains, wipe with a soft cloth moistened with a mild detergent solution and wrung dry,
then wipe with a dry soft cloth.
Do not use benzene, thinner, or any other chemical product on the camera, the cables or the
accessories, as this may cause deterioration.
9.1.2 Lens
Note
•
The cleaning of all optical elements, in particular when coated, risks deterioration of
it surface.
•
Minimize cleaning by storing the optical elements in their case, or covering the
element and its support by a protective cover when not used.
Use the following procedure to clean the lens surface.
Procedure
1
Blow or brush loose particles from surface. Don’t let them contaminate your work area.
Use air from a can or a filtered source.
2
If dust remains, take a lens tissue (ref. Melles GRIOT: 18LAB020) and wipe surface
gently in circle from center to exterior.
3
If necessary, change the lens tissue and repeat the operation
4
If dust persists, apply propanol-2 RECTAPUR 20 (ref. PROLABO: 839.322) to your
lens tissue. Use slow, even, light pressure working from edge to edge across the optic.
9.2 Cooler
General
The microcooler is designed to provide maintenance-free operation for many thousands of
hours. The microcooler contains pressurized helium gas.
After several thousand hours of operation the gas pressure decreases, and cooler service is
required to restore cooler performance. The cooler also contains microball bearings, which
may exhibit wear-out by becoming louder.
Signs to watch for
The FLIR Systems microcooler is equipped with a closed-loop speed regulator, which adjusts
the cooler motor speed to regulate the detector temperature.
Typically, the cooler runs at maximum speed for 7–10 minutes (depending on model), and
then slows down to about 40% of the maximum speed. As the gas pressure degrades, the
motor continues at maximum speed for longer and longer periods to reach operating
temperature.
Eventually, as the helium pressure decreases, the motor will loose the ability to reach and/or
maintain operating temperature. When this occurs, the camera must be returned to FLIR
Systems Customer Service Department for service.
