- Page 11 REGULATIONS Pump priming Before regulating, the oil pump must be primed as follows: Before starting up the burner, make sure the storage tank return pipe is not blocked. Blockage could cause the pump seal to break. Start up the burner, open the solenoid valve and vent the air at the pressure gauge connection, then illuminate the photoresi- stor.

- Page 15 BURNER IGNITION PROCEDURE Oil pump Check that mains voltage corresponds to the voltage indicated on the rating plate. Check oil pressure in the feeding hydraulic circuit (about 2 bars at 50°C). Check that the oil supply cocks are open. Check that the motor rotates anticlockwise looking at the motor from the cooling cover. Manually operate the burner motor command contactor until the pre-heating tank and entire burner oil circuit is full.
- Page 16 PART II: OPERATION MANUAL LIMITATIONS ON THE USE OF THE EQUIPMENT THE BURNER HAS BEEN DESIGNED TO OPERATE ONLY AFTER IT HAS BEEN CORRECTLY CONNECTED TO A HEAT GENERATING UNIT (E.G. BOILERS, WARM AIR HEATERS, FURNACES ETC.) AND ALL OTHER USES MUST BE CONSI- DERED IMPROPER AND THEREFORE DANGEROUS.

- Page 31 SUNTEC PUMPS E SERIE The SUNTEC oil pumps incorporate a pressure regulating valve with cut-off function. The E pumps can also be used with heavy oil. The gear set draws oil from the tank through the built-in filter and transfers it to the valve that regulates the oil pressure to the nozzle line. All oil which does not go through the nozzle line will be dumped through the valve back to the return line, in two pipe installation or, if it is a one-pipe installation, back to the suction port in the gear-set (in that case, the by-pass plug must be removed from the return port, and the return port sea- led by steel plug and washer).
