5.6 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. This filter prevents
air pollution by oil mist.
• In order to carry off the oil mist, connect a suitable hose to the exhaust
port of the vacuum pump (RZ-2.5 and RC-6: ½", DUO 5 or DUO 10 ¾").
• 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).

5.7 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.
