Routine Maintenance

Regularly clean the water filter at the injector inlet and the fertilizer suction filter.
If its planned not to operate the injector for a long period, operate the injector for a few minutes
with the metering tube immersed in a tank with clean water to remove fertilizer residues from the
injector preventing them solidifying in the injector.
If there is fear of frost and the temperature falling below 4°C (39°F) empty the water from the
injector. To do this, close the entry and exit valves securely. Open and dismantle the 3/4" record
that connects the suction pipe. Press the suction check valve using a finger or a thin rod, allowing
all the water that has collected in the injector to drain out while pressing the air release valve at
the top of the injector.
