3.3 General description of the working cycles
After switching on the unit, the display shows the model number and the SW version for few seconds:
Following screen is then displayed including information on the status of the unit:
a) the weight of the refrigerant in the internal tank
b) the temperature of the gas in the tank and
c) the corresponding (theoretic) pressure value of R134a
d) the currnt date and time

Meaning
Refrigerant level in the internal tank and weight value
Temperature of the refirgerant in the internal tank and (theoretical) gas max presssure value
3.3.1 Release of Non-Condensable Gases
If the value of the (theoretical) gas pressure (see above point c) -
calculated on the base of the gas temperature measured by the
temperature probe - is significantly higher than the actual pressure
of the gas in the tank (you may read its value by means of the tank
pressure gauge, see above fig.n.2) the refrigerant is mixed with
non-condensable gases. (NCG).The unit automatically releases the
gases during the vacuum phase through the NG release valve You
may also pull the ring on the max pressure valve to release the
NCG's until the theoretical and the actual pressure comply.
Note:
if the value on the pressure gauge, on the opposite, is lower
than the theoretical one, the gas quantity in the tank is too low.
