Pump Boost
pins 1 and 2
5.6 Pump Boost
The Pump Boost (PB) function has been designed
to facilitate filling the fuel hoses during installation
and maintenance.
Connect the PB by turning the maintenance per-
son’s switch to the vent position and connecting the
J6 pins 1 and 2 of the maintenance coupling. The
pump will click once and by holding the pins together
for at least two seconds, the PB will work. There is
no vent position on the control panels of stoves.
The integrator stops the PB after the pump has
pumped 300 times; by opening the studs, the pump
will pump another 300 times. The PB will stop imme-
diately if you open the pins. If you want to start the
PB, again must turn the switch to the 0 position (> 1
sec.).
The PB works when the operating voltage is more
than 11 V and the over-heating protector T3 is not on.
The PB function may only be
used in situations where the
device is completely “cold” or if
the fuel hose is empty.
