MAINTENANCE

8. Maintenance
ELECTROCUTION hazard!
There is a risk of fatal electric shocks when
performing work on electrical devices. With
all maintenance or repair work, the pump
must be disconnected from the mains and
secured against being switched on again
without permission. Damage to the power
supply cable may only be rectified by a quali-
fied electrician.
FATAL injury hazard due to impermissible
work!
Maintenance and repair work which may
impair explosion protection may only be per-
formed by the manufacturer or by authorized
service centers.
Also note the additional information in the
appendix!
• Before performing maintenance or repair work,
switch off and dismount the pump as described in
the "Decommissioning/disposal" section.
• After completing maintenance or repair work, the
pump must be installed and connected according
to the Installation section.
• The pump must be switched on as described in
the "Commissioning" section.
Note the following information:
• All maintenance and repair work must be carried
out by Wilo customer service, authorized service
centers or by trained specialist personnel with ut-
most care, in a safe workplace. Proper protective
clothing is to be worn.
• This manual must be available to the maintenance
personnel and its instructions must be followed.
Only the maintenance and repair work listed here
may be performed.
Further work and/or structural changes may
only be carried out by Wilo customer service.
• When carrying out work in basins and/or con-
tainers, the respective local protection measures
must be observed in all cases. A second person
must be present for safety reasons.
• Only lifting equipment that is in a technically
perfect condition and load-carrying equipment
that has been officially approved may be used for
lowering and raising the pump. When lifting and
lowering the pump, make sure that it does not
become jammed. If, however, the pump does be-
come jammed, the lifting forces must not exceed
1.2 x the pump weight! The maximum bearing
capacity should never be exceeded!
Make sure that all fastening devices, ropes and
safety devices of the lifting equipment are in
a technically perfect condition. Work may only
commence if the lifting equipment has been
checked and found to be in perfect working
order. If it is not inspected, fatal injuries may
result.
