Assembly and Installation
5.1
Unpacking
Carefully unpack the Laboratory-Vacuum-System.
Check the system for:
Transport damage,
Conformity with the specifications of the supply contract (type, electrical supply data),
Completeness of the delivery.
Please inform us without delay if there are discrepancies between the delivery and the con-
tractually agreed scope of delivery, or if damage is detected.
Please take note of the general terms of business of the manufacturing firm.
In case of a claim under warranty, the device must be returned in packaging that is
suitable for protecting it during transport.
5.2
Installation and Connection
Set the Laboratory-Vacuum-System on a flat and horizontal surface.
Remove the protective caps on the connections.
Connect the intake connector of the LVS to your apparatus with vacuum hose DN 8.
Connect the cooling water tube to the emission condenser.
The cooling water return flow must be unpressurized.
Connect the air exhaust to the central air exhaust system.
Check that the connections are properly seated.
Connect the Laboratory-Vacuum-System to the power supply. (LVS with controller extern,
see chapter 3.1.3.1)
5.2.1
General instructions
Observe the basic safety instructions when using the LVS.
The pressure device regulation 2014/68/EU must be observed if devices with an
overpressure of 0.5 bar or more are connected.
The pressures at the intake and exhaust sides of the diaphragm pump at the time it is
switched on must correspond to the specifications of DIN 28432.
In order to avoid pumping speed losses, all the vacuum connecting hoses used should have
a large nominal diameter and should be laid out so that the lengths are as short as possible.
Avoid rigid connections. They must be assembled carefully in order to achieve a low leak
rate.
We recommend fitting
non-return valves
(order no. 720327) for applications with several
consumers.
The upstream
separator
on the intake-side serves to protect the diaphragm pump and the
vacuum sensor from condensates and mechanical contamination. It must be used for an ap-
plication. The level in the separator must be monitored and the separator emptied regularly.
The currently valid regulations must be observed when disposing of waste. The separator on
the intake-side can only be removed and emptied after the system has been vented.
