PB1 pumps are supplied with service switch, safety fuse, 4 m cable and crocodile clips for connection to the
battery.
The fuse specifications are indicated for each model on its body and in the technical specifications section
(Chap. 2.3).
For proper installation and electrical maintenance of the system, please follow these instructions:
- make sure the power lines are not live when installing or carrying out maintenance operations on the system
- use cables with minimum section, rated voltages and type of installation suitable for the system’s specifications
- always use a fuse that is suitable to the current required by the pump
CAUTION! The pumps are provided without safety devices such as fuses (only for the PB
85 model), motor protectors, systems against accidental restart after a power failure. The
switch, if any, will only start/stop the pump. It is therefore the direct responsibility of the
installer to connect the pump to the power source in compliance with the regulations in force
in the country of use.
6 - INTENDED USE
6.1 - Preliminary checks and start-up
After ensuring there is diesel fuel in the suction tank, that all pipes and components on the hydraulic line are in good
condition and properly sealed, and the nozzle is closed, the pump can be started.
After inserting the nozzle into the filling hole, switch the pump on, gradually release the nozzle lever and start
transferring the diesel fuel. When you have finished filling, close the nozzle and switch the pump off. If you are using
an automatic nozzle, it will automatically close as soon as you have finished filling.
WARNINGS! Never leave the filling position to prevent accidental diesel fuel spillage. Do not
start the pump before having connected the suction and discharge pipes. Do not start or stop
the pump by connecting or disconnecting any crocodile clips to the battery. Do not touch any
switches with wet hands. Avoid direct contact of the diesel fuel with skin or eyes as it may cause
harm. Use of goggles and gloves is recommended. In the event of a power failure, remember
to switch the pump off and unplug it before restoring it. Work cycles that are continuous or in
extreme conditions for the pump can cause the motor temperature to rise and its subsequent
shutdown by the circuit breaker. Switch the pump off and wait for it to cool down before resuming
work. The circuit breaker automatically switches off when the motor has cooled sufficiently.
CAUTION! During the first priming phase, the pump must be able to discharge the air, initially
present in the suction pipe and in the pump, from the discharge line. To facilitate this procedure,
make sure the nozzle or the discharge outlet is kept open. If an automatic nozzle is installed on
the discharge line, it is recommended to temporarily disassemble the nozzle to facilitate pump
suction during first start-up.
