MENU DESCRIPTION
Main menu and main working cycle description
After switching on the unit displays the SW version and performs an automatic test to check if there are any
gas leaks in the machine and, eventually, stops the operation.
Switch on the unit which will display
Firmware version and refrigerant type
The unit automatically starts a series
of tests:
A. Recovery check
B. Drain check
C. Vacuum check
D. Safety Check
In case the test fails, the unit displays
a warning message (in the case at the
right, a leak in the system). Call the
service if such a message appears.
After the test you land in the “Home
Page”:
1 – Home page Icon
2 – Gas quantity in the tank
3 – Theoretical tank pressure
4 – Actual gas temperature
NOTE:
Release of Non-Condensable Gases
If the theoretical gas tank pressure shown on the home page (see above n. 3)
calculated on the base of the gas temperature is signficantly lower than the actual
tank pressure (shown on the gas tank manometer) the refrigerant is contaminated
by non-condensable gases (NCG’s) The unit automatically releases NCG’s during
the vacuum cycle, but the user (for instance in case of failure of the NCG release
valve) may also manually release by pulling the ring on the max pressure valve until
the theoretucal and the actual presur evalues comply. NOTE: If the theoretical gas
pressure, on the opposite, is higher than the actual value shown on the tank
manometer the gas quantity in the tank is too low .
