If the fan is equipped with a shaft seal which has been
provided for connection to a barrier gas line, the shaft seal
must be connected to the barrier gas line before starting up
the fan for the first time.
The standard configuration features connection thread
G1/2".
DANGER
Ineffective shaft seal!
Fatalities or extremely serious injuries resulting from
explosion. Hazard to health as a result of leaking gases.
→ Seal the shaft seal with the impeller at a standstill using
the measures specified as follows:
Connect the shaft seal to the barrier gas line.
Ensure that sufficient barrier gas pressure is
available at all times. Perform pressure
measurements.
Inspect all connections for leaks.
Replace damaged or worn sealing rings.
In the event of damage or the onset of rust,
replace the complete shaft seal.
NOTICE!
Set the barrier gas pressure at the shaft seal approx.
30 ... 50 mbar higher than the actual pressure of the
medium within the fan housing (perform a
measurement).
NOTICE!
Refer also to the separate instructions of the shaft
seal manufacturer.
