Installation and Operation
5.1 Unpacking
Carefully unpack the chemvac Combination Pump 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 Ilmvac GmbH without delay if there are discrepancies between the delivery
and the contractually agreed scope of delivery, or if damage is detected.
Please take note of the general terms of business of ILMVAC GmbH.
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 chemvac Combination Pump System on a flat and horizontal surface.
•
Remove the protective caps on the connections.
•
Connect it to the vacuum apparatus by means of the small flange DN 16 KF or DN 25 KF.
•
Connect the pressure port to the central laboratory air evacuation duct. Ensure that the
substances fed in are absolutely safe and harmless.
•
Check that the connections are properly seated.
•
Connect the pump system to the electric supply mains and switch on.
5.3 Operation
CAUTION !
Observe the basic safety instructions when using the chemvac combination pump
system !
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.
Do not start extracting aggressive media or solvent vapours until the rotary vane pump of the
chemvac combination pump system has reached its operating temperature. Also check at
the oil level gauge for intermittent formation of foam. Operation with a "bubbler" is an excep-
tion, as flushing the gas through the oil casing is intentional in this case.
Also check the oil level against the relevant markings during operation. Top up the oil if nec-
essary.
The separator must be emptied when it becomes half full. For this purpose, vent the system
and remove the union nut from the glass vessel. Please comply with the disposal regula-
tions.
