Press ENTER
Decrease/increase the oil
quantity by means of the
buttons UP and DOWN
It is possible to set the oil quantity to be injected into the A/C system. I
t is suggested to set a quantity of
10/15 g for a medium sized A/C system
. Press EXIT to return to the main menu. By pressing the button
Enter, the unit would immediately inject the desired oilquantity.
Always check the presence of oil or dye in the relevant container
BEFORE
starting the procedure.)
Note(1):
it could be necessary to adjust the oil viscosity parameter (see menu “settings”, here following) if you notice the charged oil
quantity is not correct. This could be due to particular environment conditions; the default settings allows accurate oil charging for
medium viscosity oil at a temperature of 18-22°C.
Note(2)
:
in order to charge oil in the A/C systems always previously make a vacuum cycle.
Note(3)
:
the oil charging system is designed in order to charge
small
quantities of oil recovered from the
vehiclein during the recovery cycle. It is not recommended in case of charging bigger quantities.
3.4.2.6 Dye injection into A/C system (optional)
By selecting the icon and DYE INJECTION it is possible to set the quantity of dye liquid to be injected into
the A/C system. The procedure is similar to that used for the oil charging (see aboveI. Once set the
parameters, press EXIT as by pressing the button Enter again, the unit would immediately open the valve
for the necessary time to inject the desired quantity.
Always check the presence of oil or dye in the relevant container BEFORE starting the procedure.
3.4.2.7 Refrigerant gas recharging into A/C system
By selecting RECHARGING it is possible to set the refrigerant quantity to be injected into the A/C system (It
is furthermore be possible to derive the quantity from a data bank as shown above)
Press ENTER
Decrease/increase the
gas quantity by means of
the buttons UP and
DOWN
At the end of the cycle, the operator is requested to close the quick couplings on the vehicle in order to start
the recovery cycle of gas residuals in the connecting tubes.
Disconnect,
press ENTER
1) Current hose pressure
Note
(1)
If, on the opposite you wish to suction the gas residuals of the hoses into the vehicles' A/C system,
you should have set the hose length to the value “0” (see hereunder p “Setting the hose length” )
Note
(2)
The refrigerant charging is carried out thanks to the pressure difference between the tank and the
Ecos-150 sw 1.x.x - ver. 1.0
