have been carried out.
Cable not connected
Control system has switched off due to
overheating (temperature switch)
Safety fuse has tripped due to a blockage
of the rinsing pump (excessive current

Harmless food-grade oil may leak from a
new rinsing pump for a short time when
first used
Remedy
Switch on the filter pump, connect the power
plug
Clean the supply and/or return
Clean, replace if necessary
Check hose, and replace if necessary
Reduce line length to necessary minimum
Adjust the pump capacity accordingly
•
Remove algae and leaves from the pond
•
If the water is particularly contaminated,
change 30 % of the water to avoid damage to
the fish.
•
Optimize the water flow so that the skimmer
and/or the filter pump can draw in the dirt
particles.
•
Align the skimmer and/or filter pump in rela-
tion to the water flow so that they can draw
in dirt particles.
Reduce number of pond animals
Clean or replace screen elements
Check the position of the drum seal
Replace the drum seal
Remove a screen element and remove dirt par-
