General provisions
For connection and switching-off of the measuring device the checked line should be blocked on the central valve as much as possible to lower leak of oil and not to empty the central valve which is under pressure.
Before removal or a detachment of any components DRC necessarily block a corresponding line on the central valve. If at works on DRC to the open central valve there is even a small leak of oil in any case the subsequent check of pressure in system with comparison of the set and actual values is necessary. In case of understating of the minimum pressure replacement of the corresponding central valve is necessary.
Small leak of oil from connections at the closed central valve, occurring at joining / a detachment of the measuring device, is not critical. It is necessary to avoid repeated measurements since at each connection system leaves a few oils. At the subsequent connection it leads to pressure decrease approximately on 0,3 bar in comparison with the previous measurement. Thus the considerable quantity of measurements reduces pressure in system to minimum and more low up to a system exit out of operation.
Дэмпферы and pipelines as spare parts are delivered empty.
Filling is made only at a room temperature (nearby 20 C).
Дэмпферы are filled only in the removed condition.
It is forbidden to put the car on wheels with the closed filled system and the blocked central valves. It will necessarily lead to leaks and a system exit out of operation.
Line do not bend.
