4. Check and tighten the screws which connect the pump and the board, pump and meter. For a
better employment the unit should be placed as near as possible to level of liquid to be
pumped. (Max. distance 2m).
5. Screw the delivery hose on the fitting of the flow meter and of the filling gun.
6. We suggest using a diesel resistant rubber or plastic suction hose; spiral shaped, with minimum
as 25mm internal diameter, the same as the union. The hose must be sealed to avoid leakage.
In case a 4 meters or longer hose is employed we suggest to use the foot valve with filter.
USE AND STARTING
STARTING
Once the hoses are sealed, the feeding cable is connected and the filling gun is in rest position,
the machine can be started. After placing the hose into the tank and the gun into the filling hole,
start the pump, gradually release the lever and start Diesel transfer. Once the filling is done
release the control of the gun and switch the pump off. When the pump isn’t in use disconnect it.
FLOW METER
1. The flow meter shows how many litres of liquid were pumped by the unit. Be aware that this
device is not suitable to measure products for resale.
2. The mechanical flow meters indicate the partial (resettable) and total (no reset function) of the
litres pumped. Each time the instrument must be reset, turn the knob on the left of the unit until
all zeroes are displayed.
Calibration
The meter used in the pumping unit is calibrated at the factory. Calibration is recommended upon
initial use, after disassembly or significant wear. Meter calibration can be easily changed with the
procedure hereafter. The proving container should be at least 50 litres.
Procedure:
Fill container to a know volume
Turn the calibration screw
+Clockwise to increase the number of liters counted
-Counterclockwise to decrease the number of liters counted
1. The gunlock has been provided to make filling easier. It is forbidden to leave the gun unattend-
ed to avoid overflow.
2. Don’t operate the machine if there is no liquid inside. Don’t start the pump before connecting
suction and delivery hoses.
3. Once the gun is closed switch the motor pump off as soon as possible. THE PUMP HAS TO
WORK IN BY-PASS CONDITION FOR SHORT PERIOD: MAXIMUM 3 MINUTES.
4. In case of current losses the pump should be switched off and the plug disconnected.
5. It is strictly forbidden to use the pump with wet hands, barefooted or dipped in water.
6. In case of blackout switch the pump off and disconnect the plug to avoid unexpected starts with
liquid overflow.
7. When transferring from open-air tanks, we suggest to place the machine as far as possible to
avoid sprays and sudden dips which may cause serious damage.
MAINTENANCE
Each kind of disassembly should always be carried out when the machine is stopped, the plug
is disconnected and after emptying the pump and the flow meter. For a better operation control
every three months that there isn’t any kind of debris in the flow meter filter.
