1. Safety Precautions
Obey all relevant safety requirements (regulations and guide-
lines) and adopt suitable safety measures.
☞
Read and follow all the instructions in this manual.
☞
Inform yourself regarding:
- Hazards which can be caused by the pump;
- Hazards which can arise in your system;
- Hazards which can be caused by the medium being
pumped.
Use the equipment for the intended use only (for generation
of vacuum).
☞
Avoid pumping of suddenly decomposing gases.
☞
Adopt suitable measures to prevent any danger arising
from the formation of hot surfaces or electric sparks.
☞
Do not expose any body parts to the vacuum.
☞
Obey notes on correct vacuum and electrical connections,
see section ”Use and operation”.
☞
Make sure that the individual components are only
connected, combined and operated according to their
design and as indicated in the instructions for use.
☞
Observe the safety and accident prevention regulations.
☞
Check regularly that all safety precautions are being
complied with.
☞
Do not carry out any unauthorised conversions or
modifications on the pump.
☞
Check that mains voltage and current conform with the
equipment (see rating plate).
☞
When returning the pump to us please note the shipping
instructions in the Service Section.
Due to the residual leak rate of the equipment, there may be
an exchange of gas, albeit extremely slight, between the
environment and the vacuum system.
☞
Adopt suitable measures to prevent contamination of the
pumped substances or the environment.
Electronic equipment is never 100% fail-safe. This may lead to
an indefinite status of the equipment. Provide protective
measures against misfunction and failure.
☞
Stand still of the pump or operating a valve must not lead
to a critical dangerous situation under any circumstances.
Ensure that in case of failure the pump and the vacuum
system always will turn into a safe status.
☞
In case of diaphragm cracks or leaks in the manifold
pumped substances mighty be re-leased into the environ-
ment or into the pump housing.
☞
Obey especially notes on operation and use and
maintenance.
Use only genuine spare parts and accessories.
☞
Otherwise safety and performance of the equipment as
well as the electromagnetic compatibility of the equipment
might be reduced.
☞
Ensure that maintenance is done only by suitable trained
and supervised technicians. Obey local and national safety
regulations. If necessary the pump should be
decontaminated.
☞
Before starting maintenance work vent the system, isolate
the pump and other components from the vacuum system
and the electrical supply and allow sufficient cooling of the
pump.
