Lubricant fill level and changing the lubricants

NOTICE!
Risk of severe material damage if the quench fluid is not
compatible with the medium!
Loss of seal function if the quench fluid is not compatible with the
medium may lead to severe material damage.
— Observe the detailed specifications and instructions on
changing the lubricants in the lubricant list (
"Lubricant list" on page 187), which is part of this operating
manual, as well as the specifications in the data sheet
regarding the lubricants used.
— Regarding the quench fluid, especially consider: Due to
the possibility, though unlikely, of quench fluid entering the
working chamber and thus intruding on the process itself, the
quench fluid must be compatible with the medium in addition
to the other materials (especially with the material of the O-
rings).
NOTE!
Behavior of the quench fluid
The level of quench fluid may not drop below the minimum indi-
cated on the level indicator.
— The quench fluid can rise to the rim of the fill hole due to its
function and depending on the operating temperature. A leak
of the mechanical seal can only be assumed if the fluid over-
flows.
— A slow and slight loss of quench fluid may occur due to evap-
oration as well as due to lubrication of the mechanical seal.
— A sudden and persistently strong or complete loss of quench
fluid in vacuum operation is indicative of a leak in the mechan-
ical seal.
