Vacuum pump
NOTE
Please refer to the separate operating manual of the vacuum pump and
the exhaust filter!
The vacuum pump must be connected to the vacuum connector of the unit.
The electrical connection is located inside the housing next to the vacuum
pump.
The oil mist that escapes when the pump is in operation must be retained
or carried off by way of an oil mist separator.
• We strongly recommend using an oil mist separator. The filter prevents
air pollution by the oil mist that is emitted more or less strongly by the
pump depending on the working pressure.
• The exhaust gases must be discharged in a proper manner.
• The hose must be laid so that the condensate cannot flow back into the
pump. In the case of upward leading hoses, we recommend using a
separator (Woulfe's bottle or wash bottle).

Pressure control valve
The pressure control valve is integrated in the suction pipe between the
vacuum pump and ice condenser chamber. During certain, specified
process phases, it interrupts the volume flow to the vacuum pump (see
chapter 2.2.1 - "General information on freeze-drying")
CAUTION
The pressure control valve is integrated into the system. Only specialised
personnel is authorised to perform maintenance or repairs.
