Pentair Jung Pumpen COMPLI 310E Instructions De Service page 9

Shutting down
Set the rocker switch to "0". This shuts down the pump. The
alarm system remains ready for operation.
DANGER!
Do not use the position "0" of the selector switch for repair and
maintenance work on the control and pump, but always unplug
the unit from the mains.
Inspection
To maintain operational reliability, carry out a visual inspection
of the unit, including the pipe connections, once a month.
MAINTENANCE
Maintenance and inspection of this product must be carried
out in accordance with EN 12056-4. To ensure continued reli-
ability of service, we recommend that you take out a service
contract.
NOTICE! The maintenance of the sewage lifting station and
maintenance measures are carried out by specialists at inter-
vals of 3 months in commercial premises, multi-family homes
in 6 months or 12 months in family homes.
WARNING!
Before carrying out any works: disconnect the pump and the
controls from the mains and take steps to ensure that they
cannot be energized again.
WARNING!
Check the cable for mechanical or chemical damage. Damaged
or kinked cables must be replaced by the manufacturer.
We recommend that the following works be included in the
service:
1. Check the connection points for watertightness and in-
spect the areas surrounding the unit and the fittings.
2. Operate the shut-off valves and check that they move eas-
ily. Adjust and grease them if necessary.
3. Open and clean the swing-type check valve; check the seat
and ball (valve)
4. Clean the pump and the pipes where they connect to the
unit; check the impeller and the bearings.
CAUTION!
5. Worn impellers can have sharp edges.
6. Oil check. If necessary top up or change oil (if oil chamber
available).
7. Clean the inside of the tank (as necessary, or if especially
required); remove any grease, for example.
8. Check the condition of the collecting tank.
9. Flush the system through with water once every 2 years.
10. Inspect the electrical section of the unit. The control unit
itself is maintenance-free, but if a rechargeable battery is
fitted, then it should be checked regularly to ensure that it
is in good working order. To do so, unplug the unit from the
mains and lift the float of the level controller slowly by hand
and hold it there until the alarm is triggered. In addition,
clean the float if necessary.
When all the servicing tasks have been performed, carry out a
test run and then put the unit back into operation. The service
must be documented, giving details of the important data and
of all the tasks carried out.
QUICK TIPS FOR REMEDYING
FAULTS
The unit isn't working
• Check the mains voltage, the fuse and the ground fault cir-
cuit interrupter. Replace defective fuses only with fuses
with the same nominal value! If the fuse triggers again, call a
qualified electrician or our customer support service.
• The internal 2 A glass tube fuse (delay) for the 230/12V con-
trol transformer, the motor contactor and the 230V AC pow-
er supply are faulty. Replace defective fuses only with fuses
with the same nominal value!
• If the mains cable is damaged, it may only be replaced by the
manufacturer.
• If the float switch is obstructed, close the inlet shut-off
valve, open the maintenance cover and clear the blockage.
If the alarm is triggered and the unit does not
work:
• The thermostat in the motor windings may have switched
off the system because the pump is obstructed. In this case,
close the shut-off valve at the inlet, drain the tank, pull out
the mains plug, remove the pump module, and clear the
blockage.
Decreased pumping performance
• Check that the shut-off valve in the pressure pipe is fully
open.
• If the pressure pipe is blocked, flush water through the pres-
sure pipe to clear it.
• If the non-return valve is blocked, empty the pressure pipe
and clean the non-return valve.
• If the ventilation system is blocked, clean the ventilation
hose that leads from the pump tank and check the drilled
holes.
• If the unit works normally when it starts pumping, but be-
comes very loud towards the end, then a qualified electrician
must redefine the switch-off point in the control unit.
