Ozone is an extremely aggressive gas which - if not used properly - can damage one's
health. For this reason, ozone should never be breathed in directly.
In addition, at high doses ozone can damage the skimmer.
The dosing of ozone must be set so that no free ozone can be detected at the skimmer lid.
Deltec skimmers can be operated with 50 mg/h of ozone per pump. An ozone-resistant T-
piece should be fitted in the air hose above the skimmer pump. The free end of the T-piece
is connected to the ozonizer by means of an ozone-resistant hose. Use an air tap below the
silencer to regulate the air flow through the ozonizer.
The air is automatically sucked into the ozoniser by the skimmer pump. Should the skimmer
performance deteriorate please check the ozoniser for blockage.
Safety information:
The maximum ozone quantity of 50mg/hour per pump must not be exceeded.
-
The air passage can be reduced as a result of dust deposits in the ozonizer. This can
-
result in an increase in the water level in the skimmer, which - in extreme cases - can
overflow. To avoid this, check the ozonizer regularly to make sure that there are no
deposits of dust. If necessary, clean the ozonizer.
Never breathe in free ozone.
-
In order to avoid water damage, the ozonizer must be placed above the skinner, high
-
enough to ensure that no water can enter it when the skimmer pump is switched off.
