1.3 TRANSPoRT AND UNPAcKING
Due to its weight and dimensions, the unit can easily be moved
by hand. Inspect the package for damage and verify that the
unit is not damaged. Damage must be reported within 10 days
of receiving the unit.
For correct unpacking carefully follow these instructions:
1. Placed the case on the ground following the indications on the
package.
2. Carefully open the case, remove the unit and place it on the ground
or on a steady surface.
3. Verify that the pump and its accessories are not damaged. Remove
the plugs in the pump inlet and in the flow meter outlet.
4. Fasten the panel, placing unit on the ground or on a steady surface
in an environment with a temperature between -20° C and +50° C.
The area should be well lit and ventilated. The unit should be placed
as near as possible to the level of liquid to be pumped (maximum
height of 2 m above the liquid level).
5. Screw the delivery hose onto the flange of the flowmeter and into
the filling nozzle.
6. We suggest to use a Tuthill suction hose; or use a diesel
resistant rubber or plastic suction hose, spiral shaped, with
a 25 mm internal diameter. The hose must be liquid tight. If a
4 meter or longer hose is used, we suggest to use a foot valve
with pressure relief and screen. We suggest using a Tuthill
hose and Tuthill (nozzle to obtain optimal performance and safety.
2. USE AND STARTING
2.1 ELEcTRIcAL PoWER coNNEcTIoN (220 V)
The pump must be provided with a safety device of 30mA mini-
mum Din standard. The plug must be connected to an earthed
SHUKO socket. Do not cut or replace the provided plug.
2.2 STARTING
Once the plumbing is properly installed, the electrical cable is
connected and the filling nozzle is in the closed position, the
pump is ready to be used.
After placing the suction hose into the tank and the nozzle into
the filling hole, turn on the electrical power switch to the pump,
gradually release the nozzle lever to start diesel transfer. Once
the filling is done, close the filling nozzle and turn off the electri-
cal power switch.
The pump should be disconnected from power source when not
in use.
WARNINGS
1. The nozzle lever lock has been provided to make fil-
ling easier. Do not leave the nozzle unattended to avoid
oil overflow. Do not operate the pump without liquid. Do
not start the pump before connecting suction and deli-
very hoses.
2. Once the nozzle is closed, switch the pump off as soon
as possible.
3. In case of power loss, the pump should be switched off
and the plug disconnected to avoid unexpected starts.
4. Do not use the pump with wet hands, barefoot, or while
standing in water.
5. This machine has a 30 minutes duty cycle. If it is used
for a longer period, the temperature could raise above
60 °C.
3. MAINTENANCE
All maintenance or repair should always be carried out when the
machine is stopped, the power source is disconnected, and the
equipment has been emptied of fluid.
For a better operation, every three months inspect and clean the
flow meter screen.
