Page 4: Introduction
The CVF4 is meant for all CM, CMP, SMP, CG, CGR and CUV radiometers. However with the CMP3 and SMP3 and CGR3 the ventilation effect will be less due to the larger opening around the dome. The CVF4 is meant to run continuously. -

Page 8: Installation Procedure
4.4. Installation procedure First the CVF4 is screwed flat on its mounting plate. In case the CVF4 is mounted on a solar tracker, the tracker has to be levelled first. On our sun trackers the CVF4 is positioned such that the fan sticks out over the edge of the plate. This ensures the air inlet is never blocked (see picture of the CVF4 on the SOLYS2 Sun Tracker on the next page). - Page 9 (not secured yet). In case the CVF4 is mounted on a solar tracker, finish the alignment of the tracker first before securing the radiometer screws because tracker (and radiometer) levelling might need re-adjustment.

Page 10: Electrical Connections
Shield Earth The ground is common for the ventilator and the heater (red, blue and brown). The CVF4 has an optional 8- wire Kipp & Zonen cable for connecting the 12 VDC to the ventilator and heater. The tacho output provides a 5 Volt square wave signal. It can be connected to a data logger to (remotely) check proper operation of the CVF4. -

6. Maintenance Regular inspection of the CVF4 is advised. Depending on the location (air pollution) this can be monthly or yearly. When on site for inspection of other instruments it is advised to check the CVF4 filter. At the same time radiometer levelling and desiccant can be checked. For access to the desiccant the 2 mounting nuts have to be loosened and the top cover taken off. -
