2.1.2 Product return :
• Ground the vehicle.
• Fit a DN50 connector to the nozzle and fix it to the product
return device.
• Select the storage tank to be filled.
• If necessary, reset the meter to 0 and put a ticket in the
printer.
• Do not turn on the CENTREX MULTI 2 unit pump to carry
out this operation.
• Start measured distribution from the tanker and select
the compartment to be emptied.
• Open the valve 9.
• The liquid passes the no return valve 11, crosses the
strainer 10 and the meter 14.
• The setted check valve 8 prevents any backflow.
• When the operation is finished :
- Stop the measured distribution from the tanker.
- Open the drainage valve 12 in order to return the
residual volume to the pump, closing it again after-
wards.
- Disconnect the nozzle and reattach the DN50 plug.
- The no return valve 15 generates an extra counter
pressure requested when the storage tank is under-
ground. That avoids generating a suction effect when
the nozzle is disconnected in order to not suck any air.
- Close the valve 9.
- Print the ticket where necessary and reset the counter
to zero.
