Filling/Washing Location Requirements

When filling the sprayer with chemicals and water, it is important to avoid spot contamination by spraying chemicals in
order to protect the subsoil water resources.
A. If the sprayer is always filled on the same location, a special filling/washing location should be established. This should
have a hard, liquid-impenetrable surface (e.g. concrete), together with edges securing against run-off to the
surrounding areas. The location 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 in a larger area. This is 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 can be used. Filling
location must be no closer than:
1. 50 metres from public water supplies for drinking purposes, and
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.
D. 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.
