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.
lkW
Read and comply with this manual before installing or operating the equip-
ment.
lkW
Transport the pump at the provided handles.
Use the equipment for the intended use only (i.e. for generation of vacuum).
lkW
Prevent any part of the human body from coming
in
contact with the vacuum.
lkW
Complywith notes on correct vacuum and electrical connections, see section "Use
and operation".
lkW
Make sure thatthe individual components are onlyconnected, 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.
lkW
Equipment mustbe connected only to a suitable fused and protected electrical
supply and asuitable earth point. Failureto connectthe motorto ground may result
in
deadly electrical shock.
lkW
The supplycable maybe fitted with a moulded European IEC plug ora 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.
lkW
Checkthat mainsvoltage and current conform with the equipment (see rating plate).
lkW
If the equipment is broughtfrom cold environment into a room for operation, allow
the equipmentto warm up (payattention to watercondensation on cold surfaces).
lkW
Make sure ventilation
is
adequate if pump is installed
in
a housing or if ambient
temperature is elevated.
Complywith all relevant safety requirements (regulations and guidelines) and adopt
suitable safety measures.
lkW
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 shrinkwhen evacuated.
Due to the high compression ratio of the pumps, pressure at the outlet port might be
generated being higherthan the max. permitted pressure compatible with the mechani-
cal stability of the system.
lkW
Complywith maximum permitted pressures and pressure differences, see sec-
tion "Technical data". Do not operate the pump with overpressure atthe inlet.
Do not permitany 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. Riskof bursting!
lkW
Ensure that the system design does not allow the exhaust pipeline to become
blocked.
lkW
Avoid overpressure of more than 0.2 bar
in
case inert gas is connected.
lkW
The diameter of the inlet and outlet pipeline should be at the least as large as the
diameterof the pump connection pipelines.
