Information
The specified labor times were determined specifically for carrying out this campaign and include all
necessary preliminary and subsequent rework. The labor times may differ from the labor times published
in the Labor Operation List in PCSS.
Information
Depending on usage and environmental influences, approx. 10% of the refrigerant can escape from
the refrigerant circuit per year. This corresponds to 66 g for refrigerant R134a and 70 g for refrigerant
R1234yf during a service life of two years.
If significantly more refrigerant has escaped the refrigerant circuit, the refrigerant circuit must be
checked and the cause for the refrigerant loss eliminated. This work cannot be invoiced under the
workshop campaign number.
