ADJUSTMENTS
6.4.1 PNEUMATIC TRANSPORT OF THE FERTILIZER
In models VARIANT and TELESCOPIC equipped with fertilizer unit with pneumatic transport of
the exterior rows, adjust the airow operating the adjusting valve placed in the air reservoir (A,
Fig. 6.26) and the venturi place at the fan’s air outlet (B, Fig. 6.26).
THE AIRFLOW NECESSARY FOR THE FERTILISER TRANSPORTATION TO THE EXTERIOR ROWS CAN
DEPEND ON THE TYPE OF FERTILISER AND THE FRAME’S APERTURE CONFIGURATION.
WHEN THE ADJUSTING VALVE IS COMPLETELY OPEN (A2, FIG. 6.26) AND THE VENTURI IS AT POSI-
TION 0 (B, FIG. 6.26), THE AIRFLOW FOR THE PNEUMATIC TRANSPORT IS MAXIMUM.
WHEN NOT SPREADING FERTILIZER, THE ADJUSTING VALVE SHOULD BE CLOSED (A1, FIG. 6.26)
AND THE FAN’S VENTURI SHOULD BE AT POSITION 1 (B, FIG. 6.26).
AFTER CHANGING THE POSITION OF THE ADJUSTING VALVE, CHECK THE PRESSURE VALUES
USING THE VACUUM GAUGE (FIG. 6.25). IF NECESSARY, ADJUST THE FAN’S TURNING SPEED
TO ADAPT THE PRESSURE VALUES TO THE ONES IN THE TABLE OF SECTION 6.4 SUCTION SYS-
TEM-FAN.
