The precharge pressure changes as the gas temperature changes. After having
filled or drained nitrogen wait until the temperature has equalized before you
check the gas pressure.
To set the precharge pressure, proceed as follows:
1.
Make sure that the system is depressurized.
2.
Remove the protective cap [
7
] from the gas side of the accumulator (and remove
the sealing cap [
8
] on the bladder-type accumulator).
