ƒ Make sure that there is no risk of explosion when carrying out any type of welding
work or work with electrical devices.
2.9 During operation
ƒ Wear the following protective equipment:
– Safety footwear
– Hearing protection (in accordance with work regulations notice)
ƒ The work area in which the device is used is not a recreational area. No persons are
allowed in the work area during operation.
ƒ Depending on the process, the product is switched on and off using separate con-
trols. The product may automatically switch on following power cuts.
ƒ Users must immediately notify the person in charge of every fault or irregularity.
ƒ If hazardous defects occur, the operator must immediately deactivate the device.
Hazardous defects include:
– Malfunction of safety and monitoring devices
– Damage to housing parts
– Damage to electrical equipment
ƒ Do not reach into the suction port. The rotating parts can crush and sever limbs.
ƒ If the motor emerges during operation, the motor housing can heat up to above
40°C (104°F).
ƒ Open all gate valves in the piping on both the suction and pressure sides.
ƒ Ensure minimum water submersion by using dry-running protection.
ƒ Under normal operating conditions, the sound-pressure level of the product is below
85dB(A). However, the actual sound-pressure level depends on several factors:
– Installation depth
– Installation
– Fixation of accessories and piping
– Duty point
– Immersion depth
ƒ If the device is operated under normal operating conditions, the operator must
measure the sound pressure. From a sound-pressure level of 85dB(A), wear hearing
protection and mark out the working area!
2.10 Maintenance tasks
ƒ Wear the following protective equipment:
– Closed safety goggles
– Safety shoes
– Safety gloves for protection against cuts
ƒ Always carry out maintenance tasks outside the operating space/installation site.
ƒ Only carry out maintenance tasks mentioned in these installation and operating in-
structions.
ƒ Only original parts from the manufacturer may be used for maintenance and repairs.
Use of parts other than the original parts releases the manufacturer from any liabil-
ity.
ƒ Collect any leakage of fluid and operating fluid immediately and dispose of it ac-
cording to the locally applicable guidelines.
ƒ Store tools at the designated locations.
ƒ After completing work, reattach all safety and monitoring devices and check that
they function properly.
Changing operating fluid
In case of a defect, a pressure of several bar can build up in the motor! This pressure
escapes when the screw plugs are opened. If screw plugs are opened without due cau-
tion, they can be ejected at high speed! To avoid injuries, observe the following instruc-
tions:
ƒ Adhere to the prescribed sequence of work steps.
ƒ Unscrew the screw plugs slowly, but never unscrew them completely. As soon as the
pressure escapes (audible whistling or hissing of air), stop turning the screw plug any
further.
WARNING!Hot operating fluids can also spray out when the pressure is escaping.
This can result in scalding! To avoid injuries, allow the motor to cool down to the
ambient temperature before carrying out any work!
ƒ When the pressure has completely dissipated, fully unscrew the screw plug.
2.11 Operating fluid
In the sealing chamber, the motor is filled with white oil. Operating fluid must be re-
placed during regular maintenance work and disposed off according to the local
guidelines.
