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) 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.
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 yards (meters) from any water supplies for drinking purposes,
2) 25 yards (meters) from treatment sumps and sewer drainage systems, and
3) 50 yards (meters) from surface water (watercourses, lakes and coastal waters) and from nature reserves.
ATTENTION! Legislation and requirements vary. 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.

Filling through tank lid

Water is filled into the tank by removing the tank lid located at front of the sprayer tank which is accessible from the platform.
It is recommended to use as clean water as possible for spraying purposes. Always fill water through the strainer basket to
prevent foreign particles from entering the tank. An overhead tank can be used in order to obtain high filling capacity.
±
WARNING! Do not let the filling hose enter the tank. Keep it
outside the tank, pointing towards the filling hole. If the hose is
led into the tank and the water pressure drops at the water
supply plant, chemicals may be siphoned back and contaminate
the water supply lines and source.
±
WARNING! The water supply line should be provided with a check
valve as additional safety precaution. Follow local legislation in
force at any time.
±
WARNING! The water supply should be provided with a meter to avoid spillage by over-filling. Follow local legislation
in force at any time.
