HYDRAULIC SYSTEMS
WARNING:
A filter must be installed on the suction fuel line.
Before starting the burner make sure that the return pipe-line is not clogged: any obstruction
would cause the pump seals to break.
Warning
The pump is supplied for use with a two pipe system.
For use on a one pipe system, it is necessary to remove the by-pass
screw (A), (see figure).

The pump vacuum should not exceed a
maximum of 0.4 bar (30 cm Hg).

Beyond this limit gas is released from
the oil.

Oil lines must be completely airtight.

The return line should terminate in

the oil tank at the same level as the
70
suction line; in this case a non-return
30
valve is not required.
20
When the return line arrives over the
fuel level, a non-return valve must be
used.
This solution however is less safe than
previous one, due to the possibility of
leakage of the valve.
PRIMING THE PUMP
Start the burner and wait for the priming.
Should lock-out occur prior to the arrival
of the fuel, await at least 20 seconds
before repeating the operation.
