A gas flow rate below the nominal flow rate results
in a higher concentration of ozone and lower
ozone emissions from the system. Ensure that the
gas flow rate does not exceed the permissible
range, because the control device will otherwise
switch off the system with a fault alert.
9.3 Adjusting the cooling water flow
WARNING!
Hazardous residual voltage
The following adjustments need to be made by a
ProMinent-trained expert when the system is run‐
ning with the cabinet door open.
– Wait at least 5 minutes after the supply of
power to the plant has been interrupted by the
mains switch before touching the components
on the inside of the cabinet.
– Do not touch any electrical components while
the system is carrying current.
– Before making the following adjustments,
ensure that the high voltage section is deacti‐
vated.
This is the case if the system is working in
‘Start without ozone generation’ operating
mode with an ozone setting of 0%.
The cooling water flow rate can be adjusted at the angle
valve (24) in the system cabinet adjacent to the cooling water
inlet connection on the system.
ð
The value appears on the touch panel.
A cooling water flow rate below the nominal flow
rate results in lower ozone emissions from the
system and overheating of the ozone generator.
Ensure that the cooling water flow rate and tem‐
perature do not exceed the permissible range,
because the control device will otherwise switch off
the system with a fault alert.
The cooling water flow rate is given in the "Tech‐
nical data" chapter.
The cooling water needs to be free of bubbles.
