FIRST HYDRAULIC CIRCUIT FILLING
FUEL PIPES
After checking that the protective caps on the pump fittings have been
removed, proceed as follows:
•
Turn the switch on the burner to the “O” position to avoid the burner
automatic activation.
•
Turn to "on" position the switch (1) on the synoptic panel, making
sure that the thermostat line switch (2) is set to "O".
•
Make sure that the line voltage coincides with the one indicated in
the burner's identification plate. Make sure that the motor rotates
anti-clockwise, by observing the burner from the pump side. The
rotation direction can be determined also looking at the direction of
fan rotation through the inspection window on the back of the scroll.
To start up the motor, close the remote control switch manually by
pressing on the mobile part for a few seconds and watch the sense
of rotation of the fan.
•
If it is necessary to reverse the rotation direction, reverse the two
phases on the line input terminals (L1_L2_L3).
DANGER / ATTENTION
To positively determine the direction of rotation, wait until the
fan turns very slowly because it is quite easy to misinterpret the
direction of rotation.
•
Detach, if already attached, the flexible hoses from the intake and
return pipes.
•
Dip the end of the flexible intake hose in a tin containing either
lubricant or diesel (do not use low-viscosity products such as
petrol, kerosene, etc.).
•
Now press on the mobile part of the motor remote control switch
in order to start up the motor and therefore the pump. Wait until
the pump has sucked in an amount of lubricant equal to 1 or 2
glassfuls, then stop. This operation will prevent the pump from
operating dry and will increase the suction power.
DANGER / ATTENTION
Pump operating at 2800 r.p.m. must not work dry otherwise
they will jam (seizure) within a very short time.
•
Attach the flexible hose to the intake pipe and open any gate valves
fitted on this pipe and any other shut-off element on the fuel pipes.
•
Now press on the mobile part of the motor remote control switch to
start up the pump that extracts the fuel from the tank.
•
When you see fuel coming out of the return line (not yet connected),
stop.
DANGER / ATTENTION
If the pipe is long, it may be necessary to bleed the air out
through the cap; if the pump is not fitted with a cap, remove the
pressure gauge connector cap.
•
Connect the flexible return hose to the pipe and open any gate
valves fitted on this pipe. The burner is now ready to start up.
