Pentair Jung Pumpen 120/2 M 300 E 400 E Instructions De Service page 11

In the case of compli 300, a mains-indepen-
dent alarm device can be fitted as an acces-
sory. There is a mounting base on the tank
for this purpose.
In the case of duplex units: External 230V~
flashing light or warning light (accessory)
Connect a 230V~ lamp (1 A max.) to terminals
N and 41.
Lay an insulated wire bridge from terminal
U~ to terminal 40. The electric circuit is pro-
tected by F1.
Set Jumper BRX2 as follows:
Flashing light without BRX2
(Continuous ===)
Warning light with BRX2
(Flashing (_Π_Π_ )
OPERATION
Test run and functional check
1. Open the maintenance cover of the tank.
2. Open the shut-off valves in the inlet and
the pressure pipe.
3. Connect the unit to the power supply and
observe the indication for the rotating
field direction.
4. Fill the tank up to the switch-on level.
5. The pump will now switch on and empty
the tank. Observe the pumping process
through the maintenance opening.
6. Lift the float of the level controller slowly
by hand until it is above the switch-on
point and hold it there until the alarm is
triggered.
7. Then close the maintenance opening with
the cover and seal.
8. Check to ensure that the tank, fittings and
pipes are watertight, by carrying out sev-
eral switching runs.
Automatic operation
Automatic operation is the normal operating
mode of the unit. The rocker switch must be
set to "Automatic". The integrated level con-
troller switches the pump on and off depend-
ing on the water level in the tank. A green
LED lights up when the pump is operating (in
the case of compli 300 when it is ready for
operation).
Attention! If unusually large quantities of
wastewater flow into the unit (e.g. when a
pool is drained), partially close the shut-off
valve at the inlet until the unit can operate
normally again, switching on and off, (not
pumping continuously, since this could over-
heat the pump motor).
Manual operation
Set the rocker switch to "Hand". The pump
will now operate permanently and indepen-
dently of the wastewater level. The pumping
out operation should therefore be observed
through the maintenance opening.
Shutting down
Set the rocker switch to "0". This shuts down
the pump. The alarm system remains ready
for operation.
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
We recommend that you service the equip-
ment in accordance with EN 12056-4.
To ensure continued reliability of service, we
recommend that you take out a service con-
tract.
The maintenance of the sewage
lifting station and maintenance
measures are carried out by spe-
cialists at intervals of 3 months in commer-
cial premises, multi-family homes in 6
months or 12 months in family homes.
Before carrying out any works: dis-
connect the pump and the controls
from the mains and take steps to
ensure that it cannot be emergized again.
Check the cable for mechanical or
chemical damage. A damaged or
kinked cable must be replaced.
We recommend that the following works be
included in the service:
1. Check the connection points for water-
tightness and inspect the areas sur-
rounding the unit and the fittings.
2. Operate the shut-off valves and check that
they move easily. 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.
Worn impellers can have sharp
edges.
5. Oil check. If necessary top up or change
oil (if oil chamber available).
6. Clean the inside of the tank (as necessary,
or if especially required); remove any
grease, for example.
7. Check the condition of the collecting tank.
8. Flush the system through with water once
every 2 years.
9. Inspect the electrical section of the unit.
The control unit itself is maintenance-
free, but if a rechargeable battery is fit-
ted, 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
ENGLISH
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 per-
formed, 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.
Oil check
(Only applies for units 08/2, 25/2 and 35/2).
First of all, unscrew the hexagon screws or
Allen screws around the pump and lift the
pump and impeller off the tank. The drain
plug is labelled "Öl". In order to check the
mechanical seal, the oil, including any resi-
due, must be drained from the oil reservoir
and collected in a clean measuring container.
∙ If the oil is contaminated with water
(milky), an oil change must be carried
out. Check again after a further 300 op-
erating hours, but at the very latest after
6 months!
∙ However, if the oil is contaminated with
both water and pollutants, then not only
the oil must be replaced, but the mechan-
ical seal as well.
For monitoring the oil reservoir, it is also
possible to retrofit the electrode of our "DKG"
seal leak detector in place of the "DKG" seal-
ing screw.
Changing the oil
(Only applies for units 08/2, 25/2 and 35/2).
To ensure operational liability, the first oil
change should be carried out after 300 oper-
ating hours, with further oil changes carried
out after every 1000 operating hours.
If the number of operating hours is very low,
an oil change should still be carried out at
least once a year.
If wastewater with strongly abrasive con-
stituents is being pumped, the oil changes
should be carried out at correspondingly
shorter intervals.
Use HLP hydraulic mineral oil, viscosity class
22 to 46, e.g. Mobil DTE 22, DTE 24, DTE 25,
to replace the oil in the oil reservoir.
The quantity of oil required is 380 cm³ for
the MultiCut pumps UC 08/2 M and UC 25/2
M, and 1000 ml for the MultiFree pumps UC
25/2 BW and 35/2 BW.
The oil reservoir may only be filled with the
specified quantity of oil. Overfilling will result
in the pump being rendered inoperable.
Checking the cutting clearance
Only for pumps with cutting system. The
housing screws for the pump, and the con-
necting and fixing screws of the installation
must be checked to ensure they are fixed se-
curely. They should be tightened if necessary.
If the pump performance decreases, or if
increasingly loud noises can be heard dur-
ing operation, or if the cutting performance
