Shutdown
Short-term:
Empty bottle.
Has the pump been exposed to condensate?
Set the VHC pro to continuous aspiration and the BVC to
maximum underpressure and allow the pump to continue
to run for a few minutes.
Has the pump been exposed to media which may damage
the pump materials or form deposits? Check and clean
pump head if necessary.
Long-term:
Take measures as described in short-term shutdown sec-
tion.
Close inlet and outlet port (e. g., with transport caps).
Store the pump in dry conditions.
The pump achieves its pumping speed, ultimate vacu-
um and vapor 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
transferred through the pump in significant amounts.
In case of excess temperature the motor is shut down by a
thermal cutout in the winding. Manual reset is necessary.
Switch off or unplug the pump. Identify cause of failure
and eliminate. Wait approx. five minutes before restarting
the pump.
Attention: In case of supply voltage below 100V (100-
120V version), the lock of the cutout might be restricted
and the pump might restart on its own after sufficient cool-
ing down. Take suitable precautions if an automatic restart
of the pump may lead to a critical dangerous situation.
After a power failure, the system will automatically start
again.
