green
red
The green light is off/ the red lights are off
The single green light indicates the correct power supply. If it is off, there is no active power supply
and Vulcan can not function. This could be caused by a malfunctioning of the power plug. Please
check if the power plug is correctly connected to the power source. Also please check if the impulse
bands are without damage. If both are in order, the electric power adaptor may be malfunctioning.
Green light is active/ all red pilot lights are off
The flashing of the red pilot lights indicates that the impulse generation is operating correctly.
Although the power supply is active, if the red lights are off, the impulse generation may not be
performing correctly. In this case, please contact the CWT office.
The green light is off/ the red lights are on
Although the green light is not illuminated which indicates the absence of power, the red lights
approve the correct impulse generation. In this case, the green lamp is simply out of order due to
a lamp malfunctioning.
My client installed Vulcan some days or weeks ago and now finds small particles and
pieces in the aerator.
This is a normal effect. The first layer of scale deposits inside the pipe are
quite loose and crumble off easily. It is typical that they can be found within the first weeks of the
operation. After that initial loose layer has been dismantled, you will normally not be able to notice any
of the deposit removal as the scale is dissolved in the water and washed away.
My client came home after a vacation and when he turned on the water for the first time,
it showed a red color.
As the water in the house has been sitting in the pipe for some days or weeks
it was soaking up the rusty color of the deposit. You will then see the red color until all water in the
piping has been flushed out and new water is pumped through after that. This is not at all caused by
Vulcan. Rather, the existence of red water in such a case simply proves that there are rusty deposits
in the piping system. Vulcan will slowly dissolve them.
The top layer of the acrylic cast looks dull or yellowish.
There are several possible reasons for a
decolorization of the acrylic surface: Cleaning the Vulcan surface should only be done with a wet cloth
and with no cleaning additives. A common mistake is to use a glass cleaner (e.g. windex) which harms
the material. Another possible reason is direct exposure to sunlight. This can also discolor the surface.
However, this is a cosmetic problem and does not influence the effectiveness of the treatment. CWT
offers a repolishing service in such cases for a small fee.
My client tells me that he thinks the unit has been working great for a while (some
months/ years) but seems to loose its effectiveness. What could be the reason behind
this? And how can I check whether or not it is working?
In order to verify results, in such
cases, we advise you to provide your client with a new aerator for one of the faucets (e.g. for the
bathroom). Please ask your client to send it back to you after a time-period of 12 weeks. How the
aerator looks after that time is a very good indicator for the performance of Vulcan.
Furthermore, we advise unplugging Vulcan for a period of 4-8 weeks and then putting it into operation
again. A rare but common phenomenon is that people get used to the Vulcan effect in the water after
time - they lose their original objectivity. By stopping Vulcan for a while, the „normal“, untreated water
will show its typical problems again. When Vulcan is then put into operation again, the change will be
obvious.
