Filling/washing location requirements
When filling the sprayer with chemicals and water it is important to avoid spot contamination by spray chemicals in order
to protect the subsoil water resources.
A. If the sprayer is always filled at the same place, a special filling/washing location should be established. This should
have a hard, liquid-impenetrable surface (e.g. concrete) securing against seepage and edges securing against run-off
to the surrounding areas. The place should be drained to an adequate receptacle (e.g. slurry tank or similar).
Any spillage or washings should be retained and diluted in order to be distributed on a larger area to ensure minimal
environmental impact and avoid build-up of larger chemical concentrations at one spot.
If no other requirements of distances exist, the following general recommendation of distance could be used. Not
closer than:
1) 50 metres from public water supplies for drinking purposes,
2) 25 metres from non-public water supplies for drinking purposes and from treatment sumps and cesspools of
drainage systems, and
3) 50 metres from surface water (watercourses, lakes and coastal waters) and from nature reserves.
B. Alternatively the sprayer can be filled in the field where the spraying is to take place. If so, choose a different location
for each refilling.
If no other requirements of distances exist, the filling should not take place closer than:
1) 300 metres from public or non-public water supplies for drinking purposes and
2) 50 metres from surface water (watercourses, lakes and coastal waters), treatment sumps, cesspools of drainage
systems, and nature reserves.

ATTENTION! Legislation and requirements vary from country to country. Always follow local legislation in force at any
time.
÷
NOTE! It is the responsibility of the sprayer owner/operator to comply with all relevant legislation. HARDI cannot
undertake any responsibilities for incorrect operation and use.
Filling of water
The tank should normally be filled 1/3 with water before adding
chemicals. Always follow the instructions given on the chemical
container!

WARNING! If the sprayer is put aside with liquid in the main tank,
all MANIFOLD valves must be closed.
