Safety
ƒ
Locally applicable laws and regulations for work safety and ac-
cident prevention must be complied with.
ƒ
Disconnect the device from the mains and secure it against be-
ing switched on again without authorisation.
ƒ
All rotating parts must be at a standstill.
ƒ
Provide adequate aeration in closed rooms.
ƒ
When working in chambers and closed spaces, a second person
must be present for safety reasons.
ƒ
Take immediate countermeasures if there is a build-up of toxic
or suffocating gases!
ƒ
Clean the device thoroughly. Disinfect devices that are used in
fluids hazardous to health!
ƒ
Make sure that there is no risk of explosion when carrying out
any type of welding work or work with electrical devices.
2.8
During operation
ƒ
Wear the following protective equipment:
–
Safety shoes
–
Ear protection (in accordance with the notice of the work
regulations)
ƒ
Work area of the device is not a recreational area. No persons
are allowed in the work area during operation.
ƒ
The operator must immediately report any faults or irregularit-
ies to their line manager.
ƒ
If safety-endangering defects occur, the operator must imme-
diately deactivate the device:
–
Malfunction of the safety and monitoring device
–
Damage to the housing parts
–
Damage to the electrical equipment
ƒ
Never 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 the suction and pressure
side.
ƒ
Ensure minimum water submersion through dry-running pro-
tection.
ƒ
Under normal operating conditions, the sound pressure level of
the device is below 85 dB(A). However, the actual sound-pres-
sure level depends on several factors:
–
Installation depth
–
Installation
–
Fixation of accessories and pipe
–
Duty point
–
Immersion depth
ƒ
If the device is operated under normal operating conditions,
the operator must measure the sound pressure. Ear protection
