Preventing condensate return flow
Preventing backlog
in the exhaust line
Condensate can damage the pump head. Condensate must never
flow back through the hose line into the outlet and into the pump
head. Liquid is not allowed to collect in the exhaust line.
ð
Prevent condensate return flow by using a separator. Conden-
sate is not allowed to enter the inner housing through the hose
lines.
ð If possible, lay the exhaust hose so that it is descending from
the outlet; i.e. running downward, so that no backlog can form.
ð Incorrect measurement due to blocked vacuum line, e.g. con-
densate in the vacuum line can distort the measurements of the
vacuum sensor.
ð
Prevent excess pressure in the suction hose (>/ 1060 mbar
[>/ 795 Torr]).
Dangers during ventilation
Looking out for dan-
gers during ventila-
tion
Depending on the process, a potentially explosive mixture can form
in installations or other dangerous situations can occur.
Dangers due to residual energy
Possible residual en-
ergies
After the vacuum pump has been switched off and disconnected
from the power network, dangers may still be present due to resid-
ual energies:
n
Thermal energy: Motor waste heat, hot surface, compression
heat.
n
Electrical energy: Installed condensers have a discharge time of
up to 3 minutes.
Please note the following before performing actions:
ð
Allow the vacuum pump to cool down.
ð Wait until the condenser have discharged.
