Safety
Thermal hazards
Most of the pump and drive surfaces can become hot during operation.
The surfaces in question also remain hot after switching off the unit. These surfaces
may only be touched with extreme caution. Wear protective gloves if it is essential to
touch hot surfaces.
Make sure that the drained water is not too hot for more intensive contact with skin.
Install appropriate equipment to safeguard against contact with components that may
become hot.
Hazard due to articles of clothing or other objects being caught
To avoid the dangers presented by the rotating parts of the device:
ƒ
Do not wear loose or frayed clothing or jewellery.
ƒ
Do not dismantle devices for protecting against accidental contact with moving
parts (e.g. coupling guard).
ƒ
Only put the device into operation once this protection is in place.
ƒ
The devices for protecting against accidental contact with moving parts may only be
removed when the system is at a standstill.
Hazards due to noise
Observe the applicable health and safety regulations. If the device is operated under
normal operating conditions, the operator must measure the sound pressure.
Sound pressure levels of 80 dB(A) and above must be noted in the work regulations!
The operator must also introduce the following preventative measures:
ƒ
Inform the operating personnel
ƒ
Provide hearing protection
For a sound pressure level of 85 dB(A) and above, the operator must:
ƒ
Make it a mandatory requirement to wear hearing protection
ƒ
Demarcate the noisy areas
ƒ
Take measures to reduce noise (e.g. insulation, noise barriers)
Leakages
Observe local standards and regulations. Avoid pump leakages to protect persons and
the environment against hazardous (explosive, toxic or hot) substances.
Ensure that a dry run of the pump is not possible. A dry run can damage the shaft seal
and thereby cause leakages.
ƒ
Wear the following protective equipment:
–
Sealed safety goggles
–
Safety shoes
–
Safety gloves for protection against cuts
ƒ
Only carry out the maintenance tasks described in these installation and operating
instructions.
ƒ
Only original parts from the manufacturer may be used for maintenance and repairs.
Use of parts other than original parts releases the manufacturer from any liability.
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.
The operator must:
ƒ
Provide the installation and operating instructions in a language which the personnel
can understand.
ƒ
Make sure that personnel are suitably trained for the specified work.
ƒ
Ensure that safety and information signs mounted on the device are always legible.
ƒ
Train personnel with regard to the operating principles of the system.
ƒ
Eliminate any risk from electrical current.
ƒ
Equip hazardous components (extremely cold, extremely hot, rotating, etc.) with an
on-site guard.
ƒ
Demarcate and cordon off the hazardous area.
ƒ
Define personnel responsibilities to ensure safe working practice.
