Remedy Of Faults; Maintenance And Cleaning - Oase Bitron Eco 120W Notice D'emploi

• Select the operating mode.
– A garden pond is subject to a number of different influencing factors that encourage algae growth (e.g. direct sun-
light, nutrient contamination, natural planting). Therefore the suitable Eco mode can only be individually deter-
mined.
– Observe the information regarding the selection of a suitable operating mode. (→ Selecting the operating mode)

Maintenance and cleaning

W A R N I N G
Possible death or severe injury from hazardous electrical voltage!
• Prior to reaching into the water, isolate (switch off and disconnect) all units/devices used in the water.
• Isolate the device (disconnect from the power supply) before carrying out any work on it.
C A U T I O N
Quartz glass and UVC lamp can break and cause cut injuries.
• Handle the quartz glass and UVC lamp with care.
Cause
Water is extremely soiled or contaminated.
Insufficient circulation of the pond water.
Capacity of the UVC lamps is not sufficient.
The quartz glass is soiled.
The quartz glass is scratched.
Unit is deactivated.
The quartz glass is soiled as the cleaning ro-
tor is not rotating.
− Inspection: Remove the unit head,
switch on the filter pump and shine a
torch into the casing.
Power plug not connected
Connection defective
Safety switch-off activated.
Seal is not sufficient.
The locking screw has not been undone.
A vacuum has formed inside the unit.

urement
Remedy
− Remove algae and leaves from the pond.
− Clean the pond thoroughly.
− Change the water, remove algae and leaves from
the pond.
− Clean the pond thoroughly.
− Change the water.
− Ensure that the pond water is sufficiently recircu-
lated.
− Place the pump in a different position.
− Use a pump with a higher circulation capacity.
Change the UVC lamps after 12000 operating hours.
Clean the quartz glass
− Replacing the quartz glass
− If the profile is worn, replace the cleaning rotor
Exit Of mode and select Eco mode.
− Clean the cleaning rotor and quartz glass
− If the delivery rate of the pump is < 10000 l/h, use
an inlet nozzle for driving the cleaning rotor.
− If the profile is worn, replace the cleaning rotor
Connect the power plug.
Check the electrical connection.
For safety reasons, the lamps are deactivated when
the unit is opened.
Defective lamps are indicated on the display by ErL1 or
ErL2.
− Check the seating of the seal.
− Tighten the screw connection.
Undo the locking screw.
Switch on the unit and allow it to warm up for a few
minutes. Subsequently pull the power plug and re-
move the unit head.
The temperature probes are precise to ± 1 °C. If other
units with temperature display are operated, the dis-
played temperature values may differ from one an-
other by up to 2 °C.
− Recommendation: The arithmetic mean of all dis-
played values produces a useful approximation of
the actual temperature.
− Greater deviations are possible if the units are ex-
posed to direct sunlight. For this reason, ensure
that the unit is installed such that it is protected
from direct sunlight.
