Page 13: Electrical Connections
C.I.B. UNIGAS Electrical connections Respect the basic safety rules. Make sure of the connection to the earthing system. do not reverse the phase and neutral connections. Fit a differential thermal magnet switch adequate for connection to the mains. ATTENTION: before executing the electrical connections, pay attention to turn the plant’s switch to OFF and be sure that the burner’s main switch is in 0 position (OFF) too. - Page 14 C.I.B. UNIGAS Fan motor direction ( and pump motor direction only for PN520 - PN525) Once the electrical connection of the burner is performed, remember to check the rotation of the motor. The motor should rotate in an counterclockwise direction looking at cooling fan. In the event of incorrect rotation reverse the three-phase supply and check again the rotation of the motor.

Page 24: Oil Circuit
C.I.B. UNIGAS Oil circuit The fuel is pushed into the pump 1 to the nozzle 3 at the delivery pressure set by the pressure governor. The solenoid valve 2 stops the fuel immission into the combustion chamber. The fuel flow rate that is not burnt goes back to the tank through the return circuit. The spill-back nozzle is feeded at constant pressure, while the return line pressure is adjusted by means of the pressure governor controlled by an actuator coupled to an adjusting cam. -
