7.1 Periodic service
The recommended service interval
for the treatment plant is 1 year.
Regular service procedures guar-
antee treatment plant functionality
and long service life.
A periodic service refers to a once
yearly inspection and service visit
at the treatment plant. During the
visit, the Uponor Infra authorised
service partner will inspect the
functional units and carry out the
procedures in the service schedule.
A written service report is always
prepared.
7.2 Service instructions for
pumps and level switches
The pumps and level switches
should be cleaned each year or
when needed. Cleaning is part of
the periodic service, but if so de-
sired, the owners of the treatment
plant may carry it out by them-
selves. The pumps can be easily
lift ed from the attachment chains.
The structure of the treatment
plant is explained in section 1.7.
Before starting service, disconnect
the voltage from the treatment
plant by disconnecting the machine
room electrical socket! (picture 45)
Use protective gloves when
servicing.
NOTE! Before service, ensure
that the electrical supply to the
treatment plant is disconnected!
NOTE! Note the risk of falling into
the tank!
7.2.1 Transfer pump cleaning
The transfer pump is located inside
the treatment plant storage tank.
1.
Before service, remove the
control unit electrical socket
from the treatment plant
machine room (picture 45).
2.
Lift the sludge basket out
of the storage tank. Use the
chain to lift the transfer pump
out of the tank (picture 46).
The pump may be rinsed to
simplify service.
3.
Check the pump casing
(picture 47) and remove any
clogging.
4.
Ensure the free rotation of the
blade wheel inside the pump
case by rotating it
(picture 48).
5.
If the blade wheel does not
move, remove the pump
bottom plate and remove any
clogging. Carefully put the
bottom plate back in its place.
6.
Finally, clean the pump
attachment chain and the
level switches. Lower the
pump back in place by using
the chain.
7.
Reattach the control unit
electrical socket.
8.
Test pump operation by mo-
ving pump plug X0 into socket
X6. The pump should imme-
diately begin pumping the
wastewater from the storage
tank into the process tank,
if water has accumulated in
the storage tank. If the pump
does not work, call service.
9.
Aft er service, reinstall the
sludge basket and sludge
pipe.
