Instruction Manual - CVF4

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.
Both the World Meteorological Organisation (WMO) and the Baseline Surface Radiation Network (BSRN) guidelines advise using
a ventilator to optimise the performance of radiometers in general.
The use of the CVF4 will:
- Increases the maintenance interval.
- Increase the accuracy of the measured data (cleaner dome / window)
- Reduce the zero offset of the radiometer.
The CVF4 is meant for all CM, CMP, SMP, CG, CGR and CUV radiometers. However with the CMP 3 and SMP3 and CGR 3 the
ventilation effect will be less due to the larger opening around the dome. The CVF4 is meant to run continuously. The heater can
either be switched on permanently for cold regions or be switched by a data logger or clock to remove dew in the morning and
be switched off afterwards. In that case the heater is operated from a 2 hours before sunrise to an hour after sunrise. This saves
power in situations where power is limited such as PV operated sites.
This manual, together with the instruction sheet, give information related to installation, maintenance, product specifications
and trouble shooting of the CVF4.
If any questions should remain, please feel free to contact your Kipp & Zonen dealer or e-mail: info@kippzonen.com .

2.2 Tools required
If the CVF4 is mounted with the supplied screws only the supplied Allan key is required. Make sure there is space to fasten the
screw under the bottom of the plate. To fasten the radiometers other Allan keys or screwdrivers may be necessary.
2.3 Preparation
Like for any radiometer with 360 ° field of view, make sure there are no obstructions that are higher than ten times their distance
when selecting a location for the CVF4.

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.
CVF4 mounting holes
When using your own mounting plate, make sure the CVF4 is mounted in the same way with the fan sticking out. The CVF4
mounting holes size and distances are indicated in the drawing below.
Ø 7 mm (2x)
The CVF4 is mounted with the supplied 4 washers and 2 screws through mounting plates from 4 to 8 mm thick. The other 2 feet
are for stability but do not need screws.
Instruction Manual - CVF4
12
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. The radiometer cable
goes (down) through the slit in the CVF4 base plate.
Finally the CVF4 cover can be put on and the two cover nuts can be fastened.
Make sure the cover is horizontal (check equal space around the radiometer dome) and the two cover nuts are fastened hand tight.

The CVF4 has a 4 wire cable for connecting the 12 VDC to the ventilator and heater. The ground is common for the ventilator,
heater and the tacho output.
The tacho output (Ut in diagram below, pin 4, yellow wire) provides a 5 Volt signal that gives two pulses per revolution. It can
be connected to a data logger to (remotely) check proper operation of the CVF4. The tacho output uses the same power supply
ground (pin 3, green wire).

0 Volt
The nominal speed is 4400 rpm, resulting in 8800 pulses per minute which equals 146 Hz on the tacho output.
Changes often indicate pollution of the filter (higher frequency), or mechanical problems with ventilator (lower frequency).
If sufficient power is available it is advised to use the heater in combination with the ventilator even in warm climates. The
heater will prevent deposition of dew in the morning.

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. This can best be done by checking the opening around the radiometer,
this should be evenly spaced.
Tip: When the tacho output is logged with the radiometer data, the performance of the ventilator can be remotely checked.

1 Refer to radiometer instruction sheet for maintenance instructions.
2 Regularly 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 part (see above drawing).
The filter cover clicks back on the ventilator.
3 Clean or replace filter every 6 months.
The interval strongly depends on the location and pollution of the air. Discolouration or pollution of the plastic cover will not
affect the proper operation of the radiometer. (the radiometer can not ‘see’ the CVF4 cover). Cleaning of the cover can be
done with water and a brush or cloth.
