Priva NUTRIJET - Operation; Basic facility requirement; Location and environmental conditions

Operation
• Make sure that you understand the Safety (page 4) instructions before operating the
unit.
• Carry out periodic maintenance in accordance with the preventative maintenance
schedule (see Maintenance and repair (page 25)).
Basic facility requirement
The installer must find the following basic facilities in the room before he positions the unit:
• a spill containment facility underneath the unit and tanks to collect chemical substances in the
event of leaks;
• connection for supply water;
• electrical connection (separately fused);
• an emergency stop feature.
Additional facilities may be required, depending on the quality of the supply water:
• Mechanical pretreatment using a filter to prevent blockages due to the sedimentation of solid
particles in the system.
• Thermal conditioning using a heat exchanger if the temperature of the supply water is too low.
Heating the supply water prevents condensation from spreading to the electrical components
(such as the EC sensor connections). Moreover, the less cold the supply water is the more
accurately the unit will dose and mix.
• Chemical pretreatment by acidification of the supply water (Priva Neutralizer) if the water contains
too much bicarbonate (see Supply water quality (page 40)).
• Disinfection using UV light, optionally combined with dosage of hydrogen peroxide (Priva Vialux
Line). This is necessary in the event of the recycling of drain water and the use of dirty surface
water.
The following facilities must be also be present before the system is allowed to be filled with fertilisers:
• personal protective equipment;
• a shower (preferably a special emergency shower to rinse-off leaked chemical substances);
• an eyewash fountain;
• a water hose to dilute and rinse away leaked chemical substances;
• safety icons on the access door(s) to the room.
Workplace
Once the unit has been started up, it will operate autonomously. As a result, there is no specific work
location.
Location and environmental conditions
Minimum free space around unit
For maintenance, inspections and changing settings (for a unit with a local operating panel), the unit
must remain accessible on all sides.
