Temporary Decommissioning - Wilo Port 600 Instrucciones De Instalación Y Funcionamiento

English
RISK of death due to malfunction!
Lifting gear and equipment must be in perfect technical condi-
tion. 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.

7.1. Temporary decommissioning

For temporary decommissioning, the pump remains installed and
the system remains connected to the mains. To protect the system
against frost damage, a pumping procedure must be carried out at
regular intervals depending on the outside temperature.
NOTE:
At sustained outside temperatures below 0 °C, particularly if use is
restricted or suspended, there is a risk of frost in the pump cham-
ber due to insufficient water exchange.
• In this case, appropriate insulation measures must be taken in the
area above the pump cover.
• If the pump chamber is not to be operated at all, we recommend
completely draining the pump chamber and pressure pipe.
7.2. Complete decommissioning for maintenance work
DANGER due to toxic substances!
Pumps that convey media hazardous to health must be decon-
taminated after being lifted out of the pump chamber before
any other work is carried out. Otherwise there is a risk of death.
Wear the necessary physical protection equipment!
BEWARE of burns!
The housing components of the pump can heat up to well above
40 °C. There is a risk of burns! After switching it off, let the
pump cool down to ambient temperature.
Dismantling is to be carried out by specialist personnel only. Be-
fore work on pressurised parts, they must be depressurised.
1. Close the inlet
2. Remove the pump cover.
3. Drain the pump chamber in manual mode.
4. Flush the pressure pipe with the flush connection connected. Then
disconnect the flush connection.
5. Close the shut-off device.
6. Have the system disconnected from the electrical supply by a quali-
fied electrician and secure it against reactivation.
7. Have the pump disconnected from the switchgear by a qualified
electrician.
8. Carefully lift the pump and discharge pipe out of the coupling. After
uncoupling, immediately twist the pump and discharge pipe by 90°
and guide it along the opposite wall of the pump chamber.
For longer stoppages, we recommend flushing out the pump cham-
ber with clear water and pumping out the sewage with a suitable
pump.
If the pump is to be removed, use the chain contained in the pump
chamber for this purpose.
