Initial Operation - Gardena 9V Betriebsanleitung

3. Initial Operation

If the Irrigation Valve is installed below ground level, it must be
installed in a sturdy and step-proof valve mount
e.g. GARDENA Art. No. 1254 / 1255 / 1290 / 1292.
1. Draw up a plan (an example is shown in the figure below).
Additional information is provided in the GARDENA Sprinkler
System Planning Guide which is available from your GARDENA
dealer.
2. For underground installation, place a layer of coarse gravel
underneath the valve mount
This ensures proper drainage of the box.
