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.
B.
C.
D.
Recovery check
Drain check
Vacuum check
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 hotline on (+61)08 8340 7055
if such a message appears.
After the test you land in the
“Home
Page”:

Theoretical

4
–
Actual
gas temperature
NOTE:
Air Pressure relief
If the
theoretical gas tank
pressure shown on the home page (see above n. 3)
calculated on the base of the gas temperature is significantly
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 theoretical and the actual pressure values 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.
