General Instructions
· Incorrect operation of the air conditioning must not be the cause of the complaint.
· During the check, the battery must be in good condition and adequately charged. (Battery voltage greater than 11.5 V).
· Pipes, hoses and individual aggregates may only be installed if the connection parts are in good condition.
· In order to equalize temperatures and prevent moisture condensing, ensure that parts that are being installed are at room temperature.
· Closure caps (plugs) may only be removed immediately before installation.
· Connection parts without closure caps and parts which have been exposed to dirt, grease or moisture must not be installed.
· The receiver/dryer must not be connected until all other parts of the system have been connected.

· A completely or partially assembled system must not be left unconnected for any longer than is absolutely necessary.
· After repairs on components of the refrigerant circuit, connections must always be checked for leaks using the leak detector.
