CAUTIONS:
The refrigerant identification equipment must
be used before checking, otherwise the service unit
may become contaminated. Contaminated
refrigerant must be disposed of as hazardous
waste. Always follow the manufacturer's
instructions when using the service units.
When recovering the refrigerant do not allow it
to enter the atmosphere under any circumstances.
Connect the R-134a refrigerant center or the set of
2
R134a pressure gauges to the refrigerant circuit
and measure the refrigerant pressure in the
refrigerant circuit.
Is a refrigerant pressure of more than 3.2 bar
measured?
Yes
