4.1 Safety
WARNING:
Ensure that the installaon technician is familiar with the safety procedures which
relate to the pump oil and the products handled by the pumping system.
WARNING:
If a hydrocarbon oil is used in this pump, do not use the pump to process oxygen in
concentraons greater than 25% in volume. If the oxygen concentraon is greater
than 25%, there is a risk of re or explosion in the oil-box of the pump
WARNING:
Do not use the pumps to pump hazardous substances.
WARNING:
Obey the safety instrucons listed below and take note of appropriate precauons.
Failure to do so can cause injury to people and damage to equipment. Prevent any
part of the human body from coming into contact with the vacuum.
Ensure that the pump is suitable for your applicaon. If there is any doubt as to the
suitability of the pump for your applicaon, refer our guidelines on vacuum pump and
vacuum system safety (see the Associated Publicaon at the end of the contents list at
