Pump Pressure Adjustment - Lamborghini Caloreclima ECO PRO 20/2 Manual Para La Instalacion Y El Mantenimento

RECOMMENDATIONS TO PROPERLY SET THE GEARED MOTOR
The geared motor is set upon testing as follows:
Red cam:
is set on approx 90°-120°
Orange cam: is set on approx 25°÷50°.
Black cam: is set in such a way that the 2nd stage valve opens when the air shut-off valve
is at 60°÷80°.
Blue cam: is set on 0°
Changes to this calibration during installation are legible even when the burner is in operation
by acting on the adjusting screws of the cams. Tightening the screws increases the angle
and positioning of the cams.
NOZZLE HOLDER ADJUSTMENT
The special shape of the draught tube and the diffuser,
the position of which is adjustable even when the burner
is working, allows optimisation of combustion parameters
right across the burner flowrate range and even in critical
working conditions. Turning the screw (1) clockwise re-
sults in the advancement of the nozzle port and a smaller
flow of air around the deflector disc. Turning the screw
counterclockwise increases the passage of air.

PUMP PRESSURE ADJUSTMENT

Pump pressure is calibrated at the factory at 10 bar for the 1st stage and 18 bar for the 2nd
stage. However, should it be necessary, pressure can be adjusted by turning the screw (P1)
for the 1st stage, and screw (P1) for the 2nd stage. To check the obtained pressure fit a pres-
sure gauge on the pressure take-off point (P).
N.B. With a scale range of up to 30 bar the working range of the pump is min 7 - max 14 bar.
