Before starting carrying out of servicing of system KB connected with демонтажем of pipelines or knots of system, it is necessary to familiarise with corresponding paragraphs of the present section in detail. At servicing of system of KB and its knots it is necessary to be guided strictly by the instructions resulted more low on a discharge and a gymnastics of system a coolant, доливу oils etc. should be removed Safety covers from unions of units of system KB only directly ahead of installation. At installation connected details grease with pure refrigerating oil of mark 525 if the system is filled хладаген volume R-12, or oil PAG in case of use of coolant R-134a. At assemblage it is authorised to use only new sealing rings of round section which preliminary dip into capacity with pure refrigerating oil: accordingly marks 525 or PAG depending on the used mark of a coolant. Greasing facilitates assemblage and helps to provide tightness of connection. At an inhaling of carving connections it is necessary to use the second wrench for deduction of a motionless detail. Only so it is possible to provide density of a joint and correct assemblage.

The definitive tightening штуцерных connections of pipelines should be made according to the inhaling moments. Insufficient or too strong inhaling of connections can lead accordingly to leaky connection or deformation of details. In both cases coolant leaks are possible.
