Setting up and installing the equipment
➨
Equipment must be connected only to a
suitable electrical supply
and a suit-
able ground point. As such, the plug must be plugged into an outlet that is proper-
ly grounded. Failure to connect the motor to ground may result in deadly electrical
shock.
The supply cable may be fitted with a molded European IEC plug or a plug suit-
able for your local electrical supply. The cable contains wires color coded as fol-
lows: green or green and yellow: ground; blue or white: neutral; brown or black:
hot.
+
Due to the high compression ratio, the pump may generate overpressure at the
outlet. Check pressure compatibility with system components (e.g., exhaust pipe-
line or exhaust valve) at the outlet.
+
Do not permit any
uncontrolled pressurizing
. Make sure that the exhaust tub-
ing cannot become blocked to avoid a
risk of bursting
!
+
Keep the electrical power cord away from heated surfaces.
• Provide a firm, level platform for the equipment. Check that the system which you
are going to evacuate is mechanically stable. Check that all fittings are secure.
Ensure a stable position of the pumping unit.
• Comply with
maximum permissible pressures
at inlet and outlet and with
max-
imum permissible pressure differences
between inlet and outlet. See section
“Technical data“. Do not operate the pump with overpressure at the inlet.
• Avoid overpressure of more than 1.2 bar absolute in the event that inert gas is
connected to the pump, to the gas ballast or to a venting valve.
•
Note
: Flexible elements will shrink when evacuated.
• Connect hoses gas tight at inlet and outlet of the pump.
• Ensure that no foreign objects can be drawn into the pump.
• Check the power source and the pump’s rating plate to be sure that the power
source and the equipment match in voltage, phase, and frequency.
• Use only oil of the recommended type. Other oils or operating fluids may cause
damage of the pump or danger.
Use
special oils
for the rotary vane pump, if, e.g.,
- the pump operates in the vicinity of potential ignition sources.
- oxygen or other flammable gases account for a large proportion of the evacu-
ated gases.
• Under normal operation conditions, pump oils and lubricants are not toxic and
their use entails no danger. Certain hazards are, however, associated with some
of these products.
• Take adequate precautions when handling pump fluids, lubricants, and solvents.
Use appropriate protective clothing, safety goggles and protective gloves to avoid
excessive contact with the skin and possible skin irritations (including dermatitis).
Do not inhale or swallow. Maintain adequate levels of hygiene and cleanliness.
Ensure that the pump location is well ventilated and that possible toxic effects of
certain vapors are avoided.
• Comply with all relevant statutory requirements and regulations concerning the
handling, storage and disposal of oil.
Attention
! Do not allow oils to be poured into or enter the drainage system or
other bodies of water.
Spillage can cause accidents, use suitable means of removing spilled oil.
