Initial Operation - Gardena 1251 Operator's Manual

2. INITIAL OPERATION

If the Irrigation Valve is installed below ground
level, it must be installed in a sturdy and step­
proof valve mount 1 (valve box) e. g. GARDENA
Art. 1254 / 1255 / 1290 / 1292.
Install the valve mount [ Fig. I1 / I2 ]:
1. Draw up a plan (see e. g. Fig. I3).
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 2 underneath the valve mount
This ensures proper drainage of the box.
3. Install the valve box with the top edge of the box
at ground level.
This avoids damage when mowing the lawn.
Please refer to the relevant operating instructions
for information on how to install the Irrigation
Valves in GARDENA Valve Boxes V1 and V3.
