en Safety
8 WILO SE 2019-01
Motor protection switch
Make provision for an on-site motor protection switch for devices without a plug! The
minimum requirement is a thermal relay/motor protection switch with temperature
compensation, differential triggering and anti-reactivation device in accordance with
the local regulations. In case of sensitive mains, make provision for the installation on-
site of other protective equipment (e.g. overvoltage, undervoltage or phase failure re-
lay, etc.).
Residual-current device (RCD)
Comply with the regulations of the local energy supply company! The use of a residual-
current device is recommended.
If persons come into contact with the device and conductive fluids, secure the connec-
tion with a residual-current device (RCD).
2.5 Use in fluids hazardous to health There is a danger of bacterial infection when using the device in fluids hazardous to
health! Thoroughly clean and disinfect the device after dismantling and prior to further
use. The operator must ensure the following:
ƒThe following protective equipment is provided and worn when cleaning the device:
–Closed safety goggles
–Breathing mask
–Protective gloves
ƒAll persons are informed about the fluid, the associated danger and its correct hand-
ling!
2.6 Transport ƒThe following protective equipment must be worn:
–Safety shoes
–Safety helmet (when using lifting equipment)
ƒAlways hold the handle to transport the device. Never pull the power supply cable!
ƒOnly use legally specified and approved lifting gear.
ƒSelect the lifting gear based on the existing conditions (weather, attachment point,
load, etc.).
ƒAlways attach the lifting gear to the attachment points (handle or lifting eyelet).
ƒThe stability of the lifting equipment must be ensured during operation.
ƒWhen using lifting equipment, a second person must be present to coordinate the
procedure if required (e.g. if the operator’s field of vision is blocked).
ƒPersons are not permitted to stand beneath suspended loads. Do not carry suspen-
ded loads over workplaces where people are present.
2.7 Installing/dismantling ƒWear the following protective equipment:
–Safety shoes
–Safety gloves for protection against cuts
–Safety helmet (when using lifting equipment)
ƒLocally applicable laws and regulations for work safety and accident prevention must
be complied with.
ƒDisconnect the device from the mains and secure it against being switched on again
without authorisation.
ƒAll rotating parts must be at a standstill.
ƒProvide adequate aeration in closed rooms.
ƒWhen working in chambers and closed spaces, a second person must be present for
safety reasons.
ƒTake immediate countermeasures if there is a build-up of toxic or suffocating gases!
ƒClean the device thoroughly. Disinfect devices that are used in fluids hazardous to
health!

area during operation.
ƒThe operator must immediately report any faults or irregularities to their line man-
ager.
ƒIf safety-endangering defects occur, the operator must immediately deactivate the
device:

Safety en
Installation and operating instructions Wilo Motor T 12 ... 72 + EMU FA, Rexa SUPRA, Rexa SOLID 9
–Malfunction of the safety and monitoring device
–Damage to the housing parts
–Damage to the electrical equipment
ƒNever reach into the suction port. The rotating parts can crush and sever limbs.
ƒIf the motor emerges during operation, the motor housing can heat up to above
40°C (104°F).
ƒOpen all gate valves in the piping on the suction and pressure side.
ƒEnsure minimum water submersion through dry-running protection.
ƒUnder normal operating conditions, the sound pressure level of the device is below
85dB(A). However, the actual sound-pressure level depends on several factors:
–Installation depth
–Installation
–Fixation of accessories and pipe
–Duty point
–Immersion depth
ƒIf the device is operated under normal operating conditions, the operator must
measure the sound pressure. Ear protection must be worn for sound pressure levels
of 85dB(A) and above and this must be noted in the work regulations!
2.9 Maintenance tasks ƒWear the following protective equipment:
–Closed safety goggles
–Safety shoes
–Safety gloves for protection against cuts
ƒAlways carry out maintenance tasks outside the operating space/installation site.
ƒOnly carry out maintenance tasks mentioned in these installation and operating in-
structions.
ƒOnly 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.
ƒCollect any leakage of fluid and operating fluid immediately and dispose of it ac-
cording to the locally applicable guidelines.
ƒStore tools at the designated locations.
ƒAfter 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:
ƒAdhere to the prescribed sequence of work steps.
ƒUnscrew 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!
ƒWhen the pressure has completely dissipated, fully unscrew the screw plug.
2.10 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.
2.11 Operator responsibilities ƒInstallation and operating instructions must be in a language which the personnel
can understand.
ƒMake sure that the personnel is relevantly trained for the specified work.
ƒProvide the necessary protective equipment and make sure that the personnel wears
it.
ƒSafety and information signs mounted on the device must be always legible.
ƒTrain the personnel pertaining to the functioning of the system.
ƒEliminate risk from electrical current.
ƒEquip hazardous components inside the system with an on-site guard.
ƒIdentify and cordon off the work area.
ƒTo ensure safe working practice, define the responsibilities of the employees.
