unit must have read and understood the operating instructions.
The unit must only be operated by trained and authorised personnel.
Personnel must be trained according to the operating instructions.
Responsibility for operation must be precisely defined in order to prevent any unclear
designation of responsibilities.
Operators must be proficient, instructed and appointed to the work.
Only trained and authorised electrical technicians may work on current-carrying
components. The unit must be disconnected from the power supply. Fuses must be
disconnected.
Safety instructions in relation to prevailing residual risks
The warning and information signs on the machine must be observed.
They provide important information about potential sources of danger.
Check that the machine is not damaged in any way before commissioning.
Do not operate the unit if electrical connections are damaged, defective or not properly
connected.
Do not operate the machine with exposed and accessible inlet or discharge sockets,
for the following reasons: Rotary piston machines are positive displacement machines
which present a risk of injury in the area around the conveying chamber.
Only suitable tools that correspond to the respective standards and design of the
bolts, nuts and screwed connections must be used.
When using cleaning agents and sprays, there is a risk of poisoning from inhalation,
and a risk of burning from coming into contact with them.
Please refer to the material safety data sheets for the operating materials used.
Avoid skin contact with or the swallowing of the lubricant.
Risk of poisoning!
Wear protective gloves.
Used lubricants are extremely harmful to the environment and can contain noxious
materials.
Lubricants must be stored and disposed of properly and in an environmentally-friendly
manner.
The appropriately fitted rotary piston machines must be used for conveying oxygen. A
lubricant especially suited for operating with oxygen must be used.
Disregarding these warnings is a
risk of fire and explosion!
Rotary piston machines with separate speed monitoring are equipped with a contact
plate on the drive shaft.
This contact plate rises above the diameter of the belt pulley and reaches operating
speed.
Disregarding the separating protective equipment is a
risk of shearing!
Warning signs for hazardous operations
Repairs and modifications to the unit must only be carried out in a professional man
-
ner. If you have any problems, please contact Aerzener After-Sales Service for assi-
stance.
Before carrying out any retrofitting, servicing or maintenance work that requires the
removal of protective equipmen, the power supply must be disconnected and the ma-
chine secured to prevent it starting up.
When replacing and cleaning the filter material (if present)
dust particles and fibres may be released into the ambient air. Do not breathe in these
materials. These materials must not reach the unprotected intake area of the rotary
piston machine.
Lubricating and control oil pipes should only be retightened or opened while the ma-
chine is in a depressurised state.
Depressurise conveying ducts before attempting to remove them.
When conveying technical gases, conveying ducts must be rinsed with a neutral gas
