Installation
5.3 Connecting the vacuum side
Remove locking cap from the vacuum flange;
– pay attention to the cone strainer and the respective O-ring in the intake port.
The connection between the pump and the vacuum chamber should be kept as short
as possible.
– Depending on the pump type, use metallic hoses or PVC hoses with flange con-
nections.
– Separators, filters etc. may be installed upstream to protect the pump (see acces-
sories). However, please observe the loss of pumping capacity due to the conduc-
tivity of the accessories.
5.4 Connecting the exhaust side
Before attaching the piping at the exhaust flange remove locking cap and insert cen-
tering ring/centering ring with nozzle with the respective O-rings.
Choose the cross-section of the exhaust line to be at least the size of the nominal
connection diameter of the vacuum pump's exhaust connection.
Piping to the pump must be suspended or supported.
– Physical forces from the piping system must not be allowed to act on vacuum
pumps.
WARNING
Toxic vapours!
Danger of poisoning when igniting and heating synthetic operating fluids (e.g. F4/F5)
above 300°C.
Observe the application instructions.
Do not allow operating fluid to make contact with tobacco products; observe safety
precautions when handling chemicals.
CAUTION
High pressure in the exhaust line!
Danger of damage to the seals and danger of the pump bursting.
Install the line without shut-off valves on the exhaust side.
If there is danger of a build-up of excess pressure (> 1500 hPa abs.) in the lines, ob-
serve all official accident prevention safety regulations.
If the exhaust gases are being extracted, the exhaust pressure must be at least
250 hPa greater than the pressure at the intake side.
