The working pressure is determined by the tension of
the spring in the regulating valve (RV). This tension
can be increased to raise the pressure and decreased
by turning the adjusting wheel clockwise and anti-
clockwise respectively.
To adjust the normal working pressure, proceed as
follows:
1. Start and warm up the engine (see section
2. With the outlet valves (AOV) closed, pull out the
knob, adjust the regulating valve (RV) until a
pressure of X bar is reached (see table).
3. Check the minimum speed of the engine. Adjust
minimum speed stop screw if necessary.
4. Open an outlet valve (AOV) sufficiently to let the
engine (E) run at maximum speed. The working
pressure must be Y bar (see table); adjust if
necessary with regulating valve (RV).
5. Check the engine maximum speed. Adjust the
maximum speed by means of adjustable eccentric
nut on top of speed regulator (SR).
6. Close the outlet valves (AOV), check that the
pressure is between Z1 and Z2 bar (see table).
Lock the regulating valve (RV) by pushing the
knob down.
7. Check the operation of the solenoid valve (SVsr)
when equipped with a generator.
Modifying the set point above the
nominal working pressure can affect the
correct working of the unit and result in
failure. After the end test in the factory
the regulating valve is sealed. Only the
AC customer center or an authorized
distributor may work on the regulating
valve!
Incorrect use/operation of the machine,
including modifying the working
pressure above the nominal pressure,
will void warranty.
Be aware not to touch hot parts when the
hood is open.
