☞
The pumped gases at the outlet of the pump or at the exhaust waste vapour
condenser have to be drained under consideration of all applicable safety regula-
tions.
The user has to check the possibility of an explosive atmosphere at the outlet of
the pump or the exhaust waste vapour condenser. Therefore for example calcu-
late the solvent partial pressure at the present cooling water temperature at the
exhaust waste vapour condenser and compare with the explosion limits of the
pumped solvent. If there is an explosive mixture, drain the gas at the outlet in
antistatic lines according to the valid explosion protection guidelines.
During operation
•
Maximum ambient temperature
: 40 °C
• If the pump is installed in altitudes of more than 1000 m above mean sea level
check compatibility with applicable safety requirements, especially IEC 60034
(motor might overheat due to insufficient cooling).
• I
f the pump has been exposed to increased ambient temperature (> 40°C)
check the pump for damage and perform a leak test if necessary (integral
leak rate < 0.1 mbar*l/s).
The pump achieves its pumping speed, ultimate total vacuum and vapour pumping
rate only at operating temperature (after approx. 15 minutes).
☞
Prevent internal condensation, transfer of liquids or dust. The diaphragm and
valves will be damaged, if liquids are pumped in significant amounts. Check the
pump regularly at the outside for
pollution or deposits
, clean the pump if neces-
sary to avoid increase of the operation temperature of the pump.
Shutdown
Short-term:
Has the pump been exposed to condensate?
Allow the pump to continue to run at atmospheric pressure for a few minutes.
Has the pump been exposed to media which may damage the pump materials or
form
deposits
?
Check and clean pump heads if necessary.
Long-term:
Take measures as described in section short-term shutdown.
Separate pump from the apparatus.
Close inlet and outlet port (e. g. with transport caps).
Close the gas ballast valve.
Store the pump in dry condition
