VD (E2.1) 07/2017 page 60/96
Maximum admissible load of the socket:
Standard 230 V / 50 Hz - 16 Amp
cUL-version 120 V / 60 Hz - 13 Amp
With cUL-version, connect only a UL listed vacuum pump with ratings of 120 V AC, 60 Hz,
and less or equal 12 Amp, 0.5 HP.
The VP 1.1 or VP 2.1 membrane pump is located in a separate transport packaging. With this option, the
mounted system, consisting of VD and vacuum module, has a total of two power supply leads.
Installation of the supplied vacuum pump
• The vacuum drying oven is mounted onto the vacuum module as described in the mounting
instructions Art. No. 7001-0137.
• The suction line is installed to the vacuum module as described in the mounting instructions Art. No.
7001-0137.
• When the pump is removed from the original packaging, place it in the vacuum module.
• Push the pre-installed suction line onto the opening of the vacuum pump (13) hose olive above the
suction-side condensate piston).
• Insert the shockproof plug of the vacuum pump into the permanently installed socket (19) in the
vacuum module.
• Push a suitable hose for removing the extracted vapors from the module onto the pressure-side
connection of the vacuum pump (hose olive at the back of the emission condenser at the top).
• Lead the hose end into an exhaust air unit.
• Connect DIN socket (20) at the vacuum module to DIN socket (16) at the chamber rear via the
supplied 1.2 m cable.
As soon as the connection between DIN sockets (16) and (20) is established, it is not possible
to manually switch the pump via switch (18).
To permit switching on and off the pump via operation line 1, keep switch (18) switched on
(position I).
WARNING
Release of extracted vapors.
Danger of injury.
Damage to oven and pump by corrosion.
Remove the extracte
d vapors from the module via a suitable hose into e.g., a fume
extractor facility.
Connect the hose to the vacuum pump outlet (hose olive at the back of the emission
condenser at the top).
You can connect a laboratory cooling system to the emission con
denser of the vacuum pumps
VP 1.1 or VP 2.1.
For operating the chemical membrane pumps VP 1.1 (MZ2C) and VP 2.1 (MD4C), please
refer to the enclosed pump manufacturer's operating manual.
