Observe the permitted gas temperature. The following values refer to the maximum ambient temperature
of the pump of 40 °C / 104°F.
Operation condition Inlet pressure Permitted gas temperature
Continuous operation > 100 mbar / 2.95 inHg (high gas load) +10 °C to +40 °C / 50°F to
104°F
Continuous operation < 100 mbar / 2.95 inHg (low gas load) 0 °C to +60 °C / 32°F to 140°F
Short-time operation (< 5 min.) < 100 mbar / 2.95 inHg (low gas load) -10 °C to +80 °C / 50°F to 176°F
Do not exceed the permitted gas inlet temperature. An excessive gas inlet temperature may diminish the
lifetime of the pump.
CAUTION
Exceeding the gas inlet temperature.
Damage to the vacuum pump.
∅ Do NOT exceed the set-point temperature of the permitted gas temperature.
With higher set-point temperature, take appropriate measures to cool down the sucked-
in gas before its entry to the vacuum pump
16.4 Vacuum module with speed controlled chemical membrane pump VP 3.1
and vacuum controller (option)
This option consists of:
• Pump stand PC 3004 Vario with speed-controlled chemical vacuum pump MD4C Vario (suction power
4.6 m
3
/h) and vacuum controller CVC3000
• Vacuum module with accompanying mounting instructions
The mounting instructions 7001-0137 delivered with the vacuum module describe
mounting the vacuum drying oven onto the vacuum module and installing the suction line
to the vacuum module.
The chemical vacuum pump and the vacuum controller are delivered ready-assembled as a vacuum
pump stand PC 3004 Vario in separate transport packaging. For installation and connection, see chap.
16.3.
Do NOT connect DIN sockets (16) and (20) when using this option.
To permit switching on and off the pump, keep switch (18) switched on (position I).
For operating the chemical membrane pump MD4C Vario, please refer to the enclosed
pump manufacturer's operating manual.
Observe the permitted gas temperature. The following values refer to the maximum ambient temperature
of the pump of 40 °C / 104°F.
