Operation
Observe the basic safety instructions when using the chemvac combination pump
system!
WARNING !
Do not block the exhaust port. Remove any exhaust caps or plugs. Otherwise, pres-
sure will build up with potential of bursting hazard with possible injury to personnel.
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.
CAUTION !
For optimum operation of the pump stand, the user may not change the factory
Bubbler setting
(see also sign at the Bubbler)
. That is only the manufacturer and/or
one of it authorized dealers reserved.
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.
5.4
Storage
The pumps are to be stored in a low-dust, interior room within the temperature range from
+ 5 to + 40 °C and at a relative air humidity < 90%.
Leave the protective elements on the suction and pressure ports. Another equally good pro-
tection may be used.
5.5
Scrap Disposal
CAUTION !
The chemvac combination pump system must be disposed of in accordance with the
2012/19/E
U
guideline and the specific national regulations.
Contaminated pump systems must be decontaminated according to the laws.
