9.2. Cycle sequence
9.2.1. Recovery cycle
Before starting recovery, the unit initializes the scales and checks that
the measurement is stable. If the unit is subject to movements, this
stabilisation may take some time due to the sloshing of the liquid in the
tank.
Throughout the recovery, the screen displays:
- ECS circuit pressure,
- amount of recovered refrigerant,
- tank pressure.
When the pressure in the ECS circuit falls below -0.3 bar, the service
unit analyses the pressures for the programmed duration.
NB: During this stage of analysis, if the pressure rises beyond 0,2 bar, the service unit restarts an automatic
recovery.
The unit extracts the refrigerant from the internal separator.
The unit empties the recovered oil into the used oil container.
The unit returns oil to the compressor and shows the quantity of
recovered refrigerant and oil.
9.2.2. Vacuum cycle
Throughout the vacuum cycle, the screen displays:
- ECS circuit pressure,
- Tank pressure,
- Remaining vacuum time.
After vacuum, the unit performs a leak test for the programmed duration.
The screen displays:
- ECS circuit pressure,
- Tank pressure,
- Remaining vacuum time.
During the leak test, if the pressure rises over than -0.8 bar, the cycle is
interrupted and the unit displays a warning message.
