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.
Care should be taken to avoid starting pump with high viscosity cold oil leading to pump and coupling damage. For
this reason, the T and TA pump body includes a drilling to accept an electric preheater. This drilling has been located
to give maximum heat transfer from the heater to the oil in the pump without there being direct contact between the
heater cartridge and the oil. Heaters should be connected for a period of time prior to starting the pump. When the
right temperature is reached, they can be switched off or left permanently switched on to maintain fluid oil in the
pump during the periodic burner shut-downs. The oil supply, pipes and filters must be separately heated.
