Vacuum Function

Display Message: PRESSURE TOO HIGH!
Before the machine begins evacuating the A/C system,
it checks for pressure in the system that might damage
the vacuum pump. If pressure greater than 0.7 bar is
detected, the machine displays
PRESSURE TOO HIGH!
CHECK CONNECTIONS
Select OK, and recover refrigerant before proceeding.
Display Message: VACUUM TIME X:XX MIN
If a leak test was programmed, and a leak is detected,
the machine displays
VACUUM TIME X:XX MIN
LEAK TEST RESULT NEGATIVE
Press ESC to exit the automatic sequence and perform
needed repairs. Press OK to continue the automatic
sequence despite the failed leak test.
To ensure an accurate leak test, it is imperative that
a thorough recovery and evacuation of the system be
performed. During the recovery process, cold spots can
develop in the A/C system. Pockets of refrigerant in
desiccant and in system oil will continue to vaporize as
the A/C system temperature equalizes toward ambient.
As this occurs, A/C system pressure will increase,
which may be interpreted by the machine as a leak.
This will vary somewhat with ambient temperature
conditions.

System Flush

Display Message: NO FLOW DETECTED
