3.1. Preparations For Installation
Fill up with operating fluid before operating the
first time (included in a separate pack in the
delivery consignment).
When transporting, use only the handle
provided for the purpose. When filled with
operating fluid, do not tilt the pump otherwise operating fluid
could escape via the vacuum and exhaust flanges.
3.2. Pump Set-Up And Location
➡
Where stationary installation is involved, anchor the pump
on site.
➡
Sight glass 5 on the front side must be visible and the gas
ballast valve readily accessible.
➡
When installing the pump in a closed housing, ensure
there is sufficient air circulation.
Maximum angle of inclination to each side 10°
Maximum erection height 2000 m N.N
Maximum and minimum ambient temperature 40 °C
and 12 °C respectively
Maximum relative humidity 85%
3. Installation
3.3. Connections, Vacuum Side
➡
Keep the connection between the vacuum chamber and
pump as short as possible.
➡
Remove all scaling and loose particles from welded lines
prior to assembly.
– To protect the pump, separators, filters and cooling traps
etc. (see Section 9. Accessories) can be fitted upstream of
the pump. However, this does mean that owing to the
conductance value of the accessory, there is a reduction
in volume flow rate.
– For the intake lines, metal or PVC hoses with small flanges
are available for laboratory work.
3.4. Connecting The Exhaust Side
Pressure can rise to dangerous levels in exhaust
lines. Therefore exhaust lines should not be
fitted with shut-off units.
If, for internal works reasons, shut-off devices
are fitted, or if there is a risk of a build up of
excess pressure in the lines, observe all official accident
prevention safety regulations.
- Lay minimum diameter exhaust lines of DN 10.
- If the exhaust gases are being extracted, the pressure of
the exhaust must not fall below 200 mbar.
- Lay lines from the pump sloping downward so that no
condensate can flow back into the pump. Otherwise fit a
separator.
- Forces from the piping system may not be allowed to act
on rotary vane pumps which are anchored.
All piping to the pump must be suspended or supported.
Exhaust gases and vapours can be detrimental
to health and/or can pollute the environment.
For this reason, when working with toxic
substances it is essential to ensure compliance
with the applicable regulations. Only officially
approved filter systems may be used to separate out these
substances. This is also applicable to operations involving
poisonous, chemically unstable, polymerising or peroxide
forming gases (see Section 9 Accessories).
