Free Selection

The Free selection menu is used to perform air conditioning maintenance step-by-step. You can perform the
same processes as in the short selection menu, but also omit individual procedures. In addition, it is possible to
enter the values for each individual process using the keypad. You can also enter the vehicle data for the service
report in this menu.
The following four processes can be performed individually in the Free selection menu:
• Recycling phase: Extraction, recycling of the refrigerant, pressure rise test, draining the waste oil.
• Vacuum phase: Evacuating the system, leak test / vacuum check.
• Filling phase: Before working on the vehicle air conditioner, a leak inspection must be carried out. The air con-
ditioner is filled with a sample of refrigerant. The pressure in the air conditioner must remain constant over a
period of 5 min. The air conditioner can only be completely filled if this test has been successfully completed.
The sample filling is then drained and the air conditioner evacuated. The final filling quantity is completely filled
up to ensure high filling accuracy. Filling with fresh oil, filling of UV additive, filling of refrigerant.
• Selecting connections: The air conditioning system has a high pressure and low pressure connection, high
pressure or low pressure only connections.
