WARNING: For a correct working of the pump, verify what follows:
Pump :
Oil temperature at the pump:
Maximum allowable pressures:

VERIFY:
- That piping system is perfectly sealed;
- That the use of hoses is avoided whenever is possible (use copper pipes preferably);
- That depression is not greater than 0,45 bar, to avoid pump's cavitation;
- That check valve is suitably designed for the duty;
The pump pressure is set at a value of 22-25 bar during the testing of burners. Before starting the burner, bleed the air
in the pump through the gauge port. Fill the piping with light-oil to facilitate the pump priming. Start the burner and
check the pump feeding pressure. In case the pump priming does not take place during the first prepurging, with a con-
sequent, subsequent lock-out of the burner, rearm the burner's lock-out to restart, by pushing the button on the control
box. If, after a successful pump priming, the burner locks-out after the prepurging, due to a fuel pressure drop in the
pump, rearm the burner's lock-out to restart the burner. Do never allow the pump working without oil for more than
three minutes.
Note: before starting the burner, check that the return pipe is open. An eventual obstruction could damage the
pump sealing device.
