AUXILIARY PUMP
In some cases (excessive distance or difference in level) it is
necessary to install a “loop-type” supply system with an auxiliary
pump, which dispenses with the connection of the burner pump
directly to the tank.
In this case the auxiliary pump can be put into operation when the
burner is started up and cut-off when the latter stops.
The electric wiring of the auxiliary pump is made by connecting
the coil (230 V) which controls the pump remote control switch
to terminals “N” (equipment terminal board) and 6 of the control
equipment.
It is important to comply strictly with the previsions set forth here
below:
- The auxiliary pump should be installed as near as possible to
the fuel to be sucked.
- Its head should meet the requirements of subject system.
- We recommend a delivery rate equal to at least that of the
burner pump.
- Connection pipes should be sized to cope with the delivery rate
of the auxiliary pump.
- Always avoid to electrically connect the auxiliary pump directly
to the remote control switch of the burner motor.
