10 Station Usage
10.1 Internal Bottle Refill
The current amount of refrigerant inside the bottle has been inserted to run a station test. For this reason, the gas
bottle has to be recharged using an external bottle before starting the station.
Total suggested quantity 3-4 Kg of refrigerant.
NB: check that the station is set on the type of gas that you want to charge (R134a or HFO1234yf)
NB: to change the type of gas you have to place the rapid couplings in the appropriate sites and click on the
desired refrigerant, confirm the choice with Enter. Do not perform the refrigerant changing if the rapid couplings are
connected to the vehicle!!
NB: if a gas type different from the last one used is selected, the station will perform an internal flushing. In this
case, connect the hoses to their seats on the side of the station and wait for the flushing to be completed.
NB: the operator must wait that the flushing step is over before proceeding with other operations. If the
flushing gets stopped, the machine will require to perform the flushing again before allowing any other
operations.
To charge the DUAL PLUS internal bottle, connect the high pressure red hose to an external bottle (liquid side!).
Open the bottle tap. Open the high pressure tap.
Use the arrow keys left/right to navigate through the menu and select "Bottle Refill".
To confirm the procedure press “Enter” on the display and the current amount of gas available will be visualized on
the display;
Use the arrow keys up/down to program the amount of gas you want to load. It will be possible to program an
amount of gas, but do not exceed 80% of the maximum capacity of the bottle;
Open the high pressure tap (fig. 7b) and confirm with "Enter" to start charging the internal bottle;
The display will show: the amount of recovered gas and the total current amount left in the bottle.
Once the amount of gas is achieved, the display will show a warning message to close the tap of the external bottle
and confirm the procedure by pressing “Enter”.
In this way the current gas inside the hoses and in the AC station circuit will be recovered
Take notice: if the programmed amount of gas is not achieved the display will show a message “the external bottle
is empty”.
THE INTERNAL BOTTLE IS EQUIPPED WITH A MECHANICAL SECURITY VALVE WHICH OPENS
AUTOMATICALLY WHEN THE PRESSURE EXCEEDS 16 BAR.
