4. Maintenance
of the skimmer head PVC thread
All Bubble King
®
skimmers
have a CNC-milled PVC-
thread, providing 100%
tightness of the head in-
stalled to the skimmer tube.
After every thorough cleans-
ing the thread should be lu-
bricated by some silicone
grease or oil, which makes
the head much easier to
spin. The surface of the
seal should be also treated
by some oil, which allows
a smoother seating of the
head and adds more tightness. The seal itself was made
from silicone and, thus, is permanently salt water proof.
5. Maintenance of the resonator / silencer
Bubble King
®
skimmers are extremely low-noise. The
noise of the air jet is perfectly dimmed by a valuable reso-
nator. The so called Helmholtz-Resonator reduces noise
by frequency phase shifting. The Royal Exclusiv
®
resona-
tors are mostly maintenance-free, because the air is not
forced through filters like in other devices, but smoothly
pass through the resonator.
Dusty air
or
accidentally dipping
the
resonator into salt
water
may require an internal cleaning to prevent plugging
from accumulated salt crystals.
Please check the resonator for obstructions by manual-
ly blowing through it. If you experience some resistance
please proceed as follows:
Open the resonator by the use of a matching M5 tool.
Thoroughly clean the resonator and reassemble. The left
figure below shows the opened resonator.
Thoroughly clean the resonator and reassemble. The cel-
lular material is only helpful for noise reduction but must
not be replaced if not desired.
Please do not overtighten the screws.
6. General
Important:
correctly seated adjustable nozzle
(only internal)
The noozle fits tightly into a notch and is removable. After
cleaning the nozzle please check that it was completely
pressed into the notch, like shown in the left figure. The
nozzle must be firmly seated. If the nozzle was not firmly
seated the consequences are equal to a wide open noz-
zle screw causing huge water flow and turbulences in the
skimmer.
6.1. Ozon plug
Please remove the hose from below the resonator and in-
stall a 12mm T-set auf. Install another hose on the lower
end of the T-set. The 12mm T-opening must be reduced
to 6mm and fitted with a nozzle. Plug the ozoniser to the
small nozzle.
Usually the depression of the Bubble King
®
pump is suf-
ficient to provide enough suction to the ozone. If the hose
is too long you may use a small air pump to feed the air-
ozone mix into the skimmer.
Under no circumstances
try to connect the 10mm
silicone hose from the Bubble King
®
pump directly to the
ozoniser.
It is definitely not functional!
The high resistance of ozonisers make it impossible to
be directly driven through the pump. The skimmer per-
formance would be instantly reduced by 90 %.The pump
would be overloaded and the safety circuit will emergency
shut off the pump to prevent damage to the pump.
