3.1. Setting Up The Pump And Location
Obey national safety regulations and safety requirements
concerning the use of vacuum and electrical equipment.
➡
Remove all packing material, remove the product from its
packing-box, remove the protective covers from the inlet
and outlet connection and keep, inspect the equipment.
➡
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 conditi-
ons.
➡
Read and obey this manual before installing or operating
the equipment.
➡
When transporting, use only the eye bolt provided for the
purpose.
3. Installation
3.2. Connecting The Vacuum Side
➡
Remove locking cap on intake connection 1.
➡
Connect pump with intake connection to the apparatus.
– Be sure the connection between the vacuum system
and the pump is flexible and as short as possible.
➡
Obey maximum permitted pressures and pressure differen-
ces, see section ”Technical data”. Do not operate the
pump with overpressure at the inlet.
➡
To protect the pump, separators, filters and cooling traps
etc.(see Section 9. Accessories) can be fitted upstream of
the pump.
➡
The diameter of the inlet line should be at the least as
large as the diameter of the pump connection.
3.3. Connecting The Exhaust Line
Pressure can rise to dangerous levels in exhaust
lines. Therefore, lay exhaust lines without shut-
off valves. Do not connect the exhaust line with
a closed system due to the danger of bursting.
In certain applications, exhaust gases and
vapors can be very hot and represent a health
and/or environment hazard.
➡
Lay exhaust lines from the pump sloping downwards so
that condensate cannot run back into the pump, otherwise
fit a separator.
➡
Do not permit any uncontrolled pressurizing (e. g. make
sure that the exhaust pipeline cannot become blocked).
Risk of bursting!
– Interchanging the connections vacuum side/ exhaust
line causes dangerous excess pressure levels.
➡
The diameter of the outlet line should be at the least as
large as the diameter of the pump connection.
The pumping speed rate can be affected by the
exhaust silencer.
It is better to use an exhaust line with extraction
system as an alternative.
If condensable vapors are present in the
exhaust, the supplied silencer can not be used.
Instead, use a length of hose which will reduce
the exhaust noise as well as allow the collection
of the condensate.
Note: Needs 1/2 inch hose nipple to make
connection.
If other pumps exhaust into this system exchan-
ge of contamination can take place.
WARNING
CAUTION
CAUTION
Transporting the pump
➡
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.
➡
Provide a firm level platform for the equipment and check
that the system to evacuated is mechanically stable and
that all fittings are secure.
Attention: Flexible elements tend to shrink when
evacuated.
To the best of our knowledge the equipment is in compliance
with the requirements of the applicable EC-directives and
harmonized standards (see “Declaration of conformity”) with
regard to design, type and model, especially directive
IEC 1010. This directive gives in detail conditions, under which
the equipment can be operated safely (see also IP degree of
protection).
➡
Adopt suitable measures in case of differences, e. g.
improve cooling measures when installation in altitudes of
more than 1000 m above mean sea level.
➡
Ambient temperature range + 12°C (50°F) ... +40 °C (100°F).
➡
If the pump is to be installed in an enclosed space make
sure that adequate cooling air can circulate. Maximum
temperature in the enclosure cannot be above 40°C
(100°F). There needs to be at least 15 cm (6 inch) between
the enclosure and the motor fan.
