A-8

A-9 CVF3 filter replacement

A.5.2 CVF4

Regular inspection of the CVF4 is advised. Depending on location

(air pollution) this can be monthly or yearly. Remember to check

the CVF4 filter.

1. Refer to Section 8, Maintenance, for pyranometer’s maintenance.

2. For access to the desiccant, the 2 mounting nuts have to be loosened and the

top cover taken off. When replacing the cover, make sure it is placed correctly

by checking that the opening around the radiometer is evenly spaced.

3. Inspect the fan inlet by unclipping the cover. For optimal air flow, make sure

the diagonal line on the cover is in line with the ventilator. The filter cover

clicks back on the ventilator.

4. Be sure to clean and replace the filter every 6 months. The interval strongly

depends on the location and air pollution. Discoloration or pollution of the

plastic cover will not affect the proper operation of the radiometer. Cleaning of

the cover can be done with water and a brush or cloth.
