c) Cleaning the outdoor sensors
Dirt on the outdoor sensors can be removed with a damp cloth.
Never use aggressive cleansing agents or other chemical solvents since they can damage the surface
of the housing or even impair operation.
Do not hose down the outdoor sensors because the outdoor sensors are only protected against rain
that comes from above and not against a jet of water from the side or from below.
d) Cleaning the rain collector
Depending on the installation site, it is possible that the wind carries dirt particles, sand, small branches etc. into the
collection funnel of the rain collector. Bigger parts could block the funnel.
You should therefore check the collection funnel regularly. Remove any leaves or other dirt you find there.
A tipping bucket is located inside the rain collector. Greater amounts of sand or dust that accumulate here can corrupt
the measurement result.
Therefore, you should disassemble the rain collector from time to time and clean the tipping bucket. We
recommend to do this at least once each year.
To disassemble or re-assemble the rain collector, proceed as follows:
1. Open the lower part of the rain collector by turning it counter clockwise
by approx. 1 cm until you can slide it down at the metal tube.
Remove next the collection funnel by turning it slightly clockwise and lift
it off.
Bear in mind the orientation of the latch lugs.
2. You can now take out the rain collector (the plastic part with the two brass pins and the cable).
Keep in mind the orientation: the connecting cable of the rain collector is located on one side.
3. Take out the tipping bucket.
Keep in mind the orientation: there is a small magnet on one side of the tipping bucket.
