SINGLE ELECTROPUMPS: Basic operation.
No further equipment is necessary for the basic operation of the Hydrodriver.
The converter does not have a mains switch, so it is connected to the power mains; it is
always live.
DIGITAL INPUT CONTROLS (SINGLE ELECTROPUMPS):
−
Start-Stop input control (A) :
to switch on the control, remove the jumper
between terminal 1 and 5.
−
Input control for regulating the economy function (C) :
to switch on the control, remove the jumper
between terminal 1 and 7.
PRESSURE REGULATION (SINGLE ELECTROPUMPS):
All the digital inputs (A – C) must be closed.
1. Unscrew the closing cap of the regulating knob.
2. Turn the knob (in a clockwise direction) until the desired pressure is obtained, referring to the data plate
on the cover of the Hydrodriver.
3. On completing regulation, close the cap of the regulating knob again accurately.
