Installation Of The Vacuum Pump Vp4 In The Pump Module (Option) - Binder VDL Series Operating Manual

6.5.3

Installation of the vacuum pump VP4 in the pump module (option)

Avoid the solvent accumulation in the pump module as this would cause the pump module to
become an occasionally or continuously / for long periods / frequently potentially explosive
area (Zone 0 or 1). The VDL vacuum drying oven located on top of the module is constructed
in device category 3 in regards to its surroundings.
Installation of the supplied vacuum pump
• The vacuum drying oven is mounted onto the pump module as described in the mounting instructions
Art. No. 7001-0137.
• The suction line to the pump module is installed as described in the mounting instructions Art. No.
7001-0137. Connect the vacuum connection (6) (small flange DN 16) on the back of the chamber to a
vacuum suction lead. When using a vacuum tube BINDER recommends the BINDER connection kit
for VP4 (chap. 6.5.5). The optional pump module has a corresponding hose outlet on its rear.
• When the pump is removed from the original packaging, place it in the pump module.
• Connect the grounding elements as described in the mounting instructions Art. no. 7001-0137.
• Connect the pre-installed suction line to the vacuum pump inlet at the suction-side small flange con-
nection located at the top of the condensate catchpot).
• Connect a conduit that is suitable for removing the extracted vapors from the pump module, onto the
pressure-side connection of the vacuum pump (hose olive on the top-back of the emission conden-
ser).
• Guide the end of the conduit into an exhaust air system, which is explosion-proof constructed in con-
sideration of any possible residual solvent contents. The operator must check if an explosive atmos-
phere may be present at the pump exit or at the exhaust waste vapor condenser. For this purpose,
use a calculation of the solvent's partial pressure at the set-up coolant temperature of the exhaust
waste vapor condenser and compare it to the explosion limits of the pumped solvent. The exhaust sol-
vent concentration should be minimized by selecting the most appropriate condensation temperature
for the solvent at the refrigeration plant that can be connected to the exhaust waste vapor condenser.
The pumped-out gases at the pump exit or the exhaust waste vapor condenser must be removed in a
controlled manner and according to applicable security regulations. If there is any possibility that an
explosive mixture could still exist, the exhaust must be removed through antistatic conduits and dis-
posed of according to the valid regulations of explosion protection.
• Establish the electrical connection at the pump's connector box. This must be carried out according to
the original user manual of the pump manufacturer and to EN 60079-0, observing the zone that has
been defined by the operator for the installation site of the pump. Equipotential bonding between the
pump housing and the housing of the vacuum drying oven must be assured by the connected equip-
ment grounding conductors of both units.
Inappropriate execution of the pump connection can lead to the risk of explosion.
Danger of ignition and explosion by inappropriate pump connection .
Serious injury or death from burns and / or explosion pressure.
 It is obligatory to follow the instructions of the pump manufacturer regarding correct
connection and commissioning.
 Observe the safety advice as in chap. 1.7.
