14.1 Cleaning
The rain[e]H3 and the collecting vessel must not be cleaned with a steel brush or similar equipment or
aggressive detergents.
All water-bearing parts should be cleaned regularly. Rinsing with clear water is sufficient in most cases to remove
contamination. It is necessary to be carefully to remove the dirt in the collecting funnel or in the discharge. Slight
contamination of the collecting vessel is not critical (for example, pollen or dust). The collecting vessel can be
cleaned with water and a mild detergent.
Keep the measuring station free from overgrown scrubs and trees.
Caution is required when cleaning the collecting vessel to avoid damage.
14.1.1 Cleaning of the Top of the Housing (Funnel)
Open the housing as described.
Pull the connector to the upper heater.
Hold the upper part of the housing with one hand and hold with the same hand the cable with the clamping con-
nector so that no dirt or water can run into the clamping connector during cleaning. Rinse the funnel with plenty
of clear water. Solid dirt can be removed with a mild detergent and a cleaning cloth.
If a mild detergent has been used for cleaning, rinse the funnel with plenty of clear water.
If necessary, remove the dirt trap spiral for cleaning and then reinsert it.
When handling with the upper part of the housing, ensure that the housing edge of the collecting surface
is not damaged!
After cleaning, reinsert the plug connector to the upper heating on the heating board.
Close the housing as described.
14.1.2 Cleaning of the Dirt Trap Spiral
To do this, grasp the dirt trap spiral in such a way that you can turn it counterclockwise a whole turn, and pull the
dirt trap spiral upwards out of the mouth of the funnel.
Clean the dirt trap spiral with a small brush and/or put it in some water with a mild detergent to rinse off the dirt.
Finally rinse the dirt trap spiral with plenty of clear water.
Reinsert the dirt trap spiral into the funnel. Try to hold the dirt trap spiral in such a way, that a full counter clockwise
turn is possible and push the dirt trap spiral from above into the mouth of the funnel.
14.1.3 Cleaning of the Protective Grid
Open the housing as described. Carefully lift off the inner protective cylinder. When lifting the protective cylinder,
be careful not to bump it against the load cell.
Press the protective grid slightly upwards through one of the drain holes with the small finger or a suitably dull
object (e.g., wooden stick) and remove it with the other hand.
Clean the protective grid with a small brush and/or place it in some water with detergent to rinse off the dirt.
Insert the cleaned protective grid lateral to the load cell into the provided gap.
Avoid contact with the load cell when inserting the protective grid!
Be careful not to cant the protective cylinder with the cables between the load cell and the main board. Close the
housing as described.
