If the machine is operated for the first time:
1. Decrease oil pumping unit pressure and ensure that all the connections are correct and there are no leaks.
2. Increase pressure progressively to suit individual flow requirements.
7. PUMP OPERATIONS
MANUAL OPTION
Output adjusting of the manual FLOWMASTER is easy: through the use of two needle valves the output adjustment can be
coarsely (par. 11.3, fig.1, pos. X) or finely adjusted (par. 11.3, fig.1, pos. Y).
To coarsely adjust:
1. Unlock the locknut of the needle valve.
2. Close the fine adjustment valve (par. 11.3, fig.1, pos. Y), by turning clockwise with a M3 allen spanner.
3. Increase or decrease the output by turning counterclockwise or clockwise, with a M5 allen spanner, the coarse
adjustment valve (par. 11.3, fig.1, pos. X).
It is advisable to make the fine adjustment only after the coarse adjustment, as follows:
-Increase or decrease the output by turning counterclockwise or clockwise, with a M3 allen spanner, the fine adjustment
valve (par. 11.3, fig.1, pos. Y) to suit individual flow requirements.
The fine adjustment valve (par. 11.3, fig.1, pos. Y) only is used for the size “A” module.
7.1 MOTORIZED OPTION
To adjust motorized FLOWMASTER output:
-Close the fine adjustment valve (par. 11.3, fig.1, pos. Y) and let the electronic control equipment start automatically in line
with the setting data.
8. TROUBLESHOOTING
The following diagnostic table indicates the main anomalies, which may be encountered, the probable causes and possible
solutions.
If you cannot solve the problem, do not attempt to disassemble parts of the machine but contact the Engineering Department of
DROPSA S.p.A., pointing out anomaly details.
9. MAINTENANCE PROCEDURE
FLOW MASTER has been designed and constructed to require a minimum of maintenance.
For an easy maintenance, it is advised to assemble the machine in an adequate location.
-To facilitate maintenance tasks without interrupting the operation of the machine, it is recommended to provide the flow
meter with an input ball valve to disconnect parts of the system.
-Periodically check pipe-joints to detect possible leaks.
-Always keep the machine unit clear to readily detect possible leaks.
-Periodically (once a year or when required) replace the refilling filter, part n°: 3130139.
