MAIOR P 35 : The pressure of SUNTEC AS 67 B pump is adjusted to 12 bar during the test phase.
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 12 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 consequent, 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 bur-
ner. 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.
Once having installed the burner, check the following items:
- The burner power feeding and the main line protection fuses
- The correct length of pipes and that sames are sealed.
- The type of fuel, which must be suitable for burner.
- The connection of boiler's thermostats and all safeties.
- The motor direction of rotation.
