Safety information!
Remove all packing material, remove the product from its packing-box, remove the
protective covers from the inlet and outlet ports and keep, inspect the equipment.
If the equipment is damaged, notify the supplier and the carrier in writing within three
days; state the item number of the product together with the order number and the
supplier’s invoice number. Retain all packing material for inspection.
Do not use the equipment if it is damaged.
If the equipment is not used immediately, replace the protective covers. Store the
equipment in suitable conditions.
☞
Read and comply with this manual before installing or operating the equip-
ment.
☞
Transport the pump at the provided handles.
Use the equipment
for the intended use only
(i.e. for generation of vacuum).
☞
Prevent any part of the human body from coming in contact with the vacuum.
☞
Comply with notes on correct vacuum and electrical connections, see section ”Use
and operation”.
☞
Make sure that the individual components are only connected, combined and oper-
ated according to their design and as indicated in the instructions for use.
Comply with
national safety regulations and safety requirements
concerning the
use of vacuum and electrical equipment.
☞
Equipment must be connected only to a
suitable fused and protected electrical
supply
and a suitable earth point. Failure to connect the motor to ground may result
in deadly electrical shock.
☞
The supply cable may be fitted with a moulded European IEC plug or a plug suitable
for your local electrical supply. If the plug has been removed or has to be removed,
the cable will contain wires colour coded as follows: green or green and yellow:
earth; blue or white: neutral; brown or black: live.
☞
Check that mains voltage and current conform with the equipment (see rating plate).
☞
If the equipment is brought from cold environment into a room for operation, allow
the equipment to warm up (pay attention to water condensation on cold surfaces).
☞
Make sure ventilation is adequate if pump is installed in a housing or if ambient
temperature is elevated.
Comply with all
relevant safety requirements
(regulations and guidelines) and adopt
suitable safety measures.
☞
Provide a firm level platform for the equipment and check that the system to be
evacuated is mechanically stable and that all fittings are secure.
Attention:
Flexible elements tend to shrink when evacuated.
Due to the high compression ratio of the pumps, pressure at the outlet port might be
generated being higher than the max. permitted pressure compatible with the mechani-
cal stability of the system.
☞
Comply with
maximum permitted pressures
and pressure differences, see sec-
tion ”Technical data”. Do not operate the pump with overpressure at the inlet.
Do not permit any
uncontrolled pressurizing
(e. g. make sure that the exhaust pipe-
line cannot become blocked). If you have an exhaust-isolation valve, make sure that
you cannot operate the equipment with the valve closed.
Risk of bursting!
☞
Ensure that the system design does not allow the exhaust pipeline to become
blocked.
☞
Avoid overpressure of more than 0.2 bar in case inert gas is connected.
☞
The diameter of the inlet and outlet pipeline should be at the least as large as the
diameter of the pump connection pipelines.
