General Instructions
Prerequisites for checking the air conditioning system according to the checking program:
· 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.
· Always use new O - rings.
· Before assembly, O - rings and all pipe and hose connection joints must be coated with special mineral oil (from the Parts and Accessories Department).
· In order to avoid twisting and kinking at the connection, the stationary part must be counterheld with a suitable tool when tightening.
· Connections may only be tightened to the prescribed torque.
· A completely or partially assembled system must not be left unsealed for any longer than is absolutely necessary.
· After repairs on components of the refrigerant circuit, connections must always be checked for leaks using a leak detector.
· Measure the amount of compressor lubricant in the replaced component.
On replacement, fill this amount of lubricant into the new component.
· Do not change the basic adjustment of the thermostatically controlled expansion valve.
Important: After reconnecting the battery, volatile memories must be reprogrammed.
With radio coding, inform the customer about the decoding.
