• The equipment is designated for an ambient and gas inlet temperature
during operation of +10 to +40°C. Never exceed these ambient and
gas inlet temperatures. If pumping / measuring gases which are not
potentially explosive, extended gas inlet temperatures are permissible.
See instructions for use, section “Gas inlet temperatures” or “Techni-
cal data”.
After any intervention at the equipment (e.g., repair / maintenance) the ul-
timate vacuum of the pump has to be checked. Only if the pump achieves
its specified ultimate vacuum is the pump’s leak rate low enough to en-
sure that no explosive atmospheres will occur in the interior of the equip-
ment.
After any intervention at the vacuum sensor, the leak rate of the equip-
ment has to be checked.
