7. First use
Before using the combi drum filter for the first time, it is
advisable to thoroughly clean the pond manually and flush the
pipelines if possible. The reason for this is to prevent the newly
started filter from immediately experiencing an interval break-
down.
Note! Electrical shock hazard.
• Always switch off the current to the system before coming
into contact with the pond water.
• Secure the system to prevent it from unintentionally being
switched on.
• Never connect the system to a power supply that is fitted
with a dimmer.
• Do not use the system in combination with a switch that
has a timer function.
• Only switch on the control box if the submersible pump
is below the water level and the electrodes are below the
surface.
7.1 Sequence for first use
• Remove the cover from the filter.
• Check all the water inlet and outlet connections.
• Check the line from the pump to the spray tube to ensure
it is hand-tight.
• Open the valves on the outflow side.
• Open one valve in the in-flow line.
• Switch on the pump.
• Adjust the flow of the pump to point downwards in case
the desired water level quickly reaches the high level.
• Check all the water inlet and outlet connections again.
• Plug the connectors into the corresponding power sockets:
The plug for the spray pump goes into the power socket labelled
"spray pump".
The plug for the drum motor goes into the power socket labelled
"drum motor".
The plug for the water pump(s) goes into the power socket
labelled "pond pump".
Any additional components connect into the power socket
labelled "spare".
Please make sure that the power sockets can support a total
output of 2500 W from "pond pump" and "spare" combined!
7.2 Adjusting water level meter
The water level meter consists of 3 stainless steel electrodes:
• The "high-level" electrode (the short coated electrode)
• The "flush-cycle" electrode: the short coated electrode
• The common electrode: the long uncoated electrode
The flush-cycle electrode is set to the highest level by default.
This means that the flush cycle is initiated when the water level
drops by approximately 90 mm before the low level is reached.
If you would like for the flush cycle to take place sooner, you
can unscrew the cable gland and place the electrode lower.
Afterwards, tighten the cable gland again.
Note! The other two electrodes do not have an adjusting function.
7.3 Flush cycle
If the pond's water quality is such that the flush cycle lasts less
than 3 minutes, then the flow into the water inlet must be reduced
to ensure that the cycle lasts for more than 3 minutes. After the
contamination in the pond has decreased, the throttling in the
drainage duct can be gradually reduced as long as you allow
for the flush cycle time mentioned above.
