1. Introduction This manual will show you how to install, use and maintain the CVF4 Ventilation Unit. The CVF4 is meant for ventilating solar radiation sensors with the purpose to keep the mounted radiometer window or dome clean from dew, precipitation and pollution. It can be used outdoors under all-weather conditions. The CVF4 has a built in heater to keep the air just above ambient temperature.

2. Installation The CVF4 consists of: - Base plate with ventilator, heater and connector - Replaceable filter plus cover - Top cover 2.
2.4 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 SOLYS 2 Sun Tracker on the next page). The locations of the CVF4 mounting holes on the SOLYS 2 top mounting plate are shown below.
Then the radiometer is mounted in the CVF4 and levelled with its own levelling feet. Afterwards the radiometer mounting screws and shoulder washers are fitted (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. After all mounting screws have been secured the cables of the CVF4 and the radiometer can be connected.

4. 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. When replacing the cover, make sure it is placed correctly.
