AUXILIARY PUMP
E
In some cases (excessive distance or difference in level) it is
N
necessary to install a "loop-type" supply system with an auxiliary
pump, which dispenses with the connection of the burner pump
G
directly to the tank.
L
In this case the auxiliary pump can be put into operation when the
burner is started up and cut-off when the latter stops.
I
The electric wiring of the auxiliary pump is made by connecting
the coil (230 V) which controls the pump remote control switch to
S
terminals 2 (N) and 6 of the control equipment for TBL 45LX and
terminals 2 (N) and 17 on the printed circuit for TBL 75LX.
H
It is important to comply strictly with the previsions set forth here

- 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.
