Volkswagen Golf Service & Repair Manual: Before operating the air conditioning system after recharging with refrigerant

After installing a new air conditioner compressor or filling with fresh refrigerant oil (e.g. after blowing out refrigerant circuit), turn compressor pulley 10 revolutions by hand before starting engine. This will prevent damage to the air conditioner compressor.
–  On 5-cyl. or 10-cyl. diesel engine, turn air conditioner compressor at overload protection 10 times by hand. Then install compressor. This will prevent damage to the air conditioner compressor.
–  Start the engine with the air conditioning system switched off (the air conditioning system magnetic clutch -N25- and the air conditioner compressor regulating valve -N280- are not activated).
–  After the engine has stabilised at its idling speed, switch on the air conditioner compressor and allow the engine to idle for at least 10 minutes at maximum cooling power.
