Checking the buffer tank
If the buffer tank is not completely filled during the start-up procedure, it is possible that
the pressure in the tank is too high compared to the pressure of the supplied water.
In this case it is possible to release some of the (air) pressure step-by-step via the
valve situated underneath the tank under a black cap, until the tank is filled. It is also
possible to measure the pressure with the same kind of meter that is used for car tyres.
To check that the pressure is not too low, the tank must be disconnected with the tap
closed. Open the tap in an area where this is possible and allow the tank to empty
completely.
If the pressure is too low, it is possible to increase the pressure using the valve and
the same system that is used to increase the pressure in car tyres. The pressure is
normally adjusted to 0.45 bar.
Procedure:
Before replacing the filters, the system must be de-pressurised.
1. Switch the humidifier off.
2. Close the supply tap.
3. Close the tap on the storage tank.
4. Disconnect one of the tubes from the storage tank and collect the excess water.
5. Exchange the filters by unscrewing the filter holders.
Beware: The filter holders still contain water.
6. Before re-installing the filters, the O-ring must be checked for damage and correct
seating.
7. The holders can be cleaned with soap and water or with chlorine, if necessary.
Rinse thoroughly afterwards.
8. After re-installing, screw the holders back into place (hand-tight!).
Starting up again:
1. Open the supply tap and let the system flush through for about 5 minutes (in order
to flush out any air).
2. Supply voltage to the pump.
3. Reconnect the tube to the storage tank.
4. Open the tap on the storage tank.
5. Wait until the system reaches the correct pressure (the discharge water will stop).
6. Switch the humidifier on again.
Ozone generator
The ceramic element must be cleaned once a year:
-
The humidifier must be disconnected from the mains.
-
Remove the screws on the side where the timer is located.
-
Remove the side panel and disconnect the timer.
-
Remove the 2 Phillips screws (bottom and top) from the stainless steel cover
plate (on the black aluminium casing).
-
Remove the ceramic element from the holder.
-
Carefully clean the ceramic element on both sides with cleaning spirit or alcohol.
-
If the vapour-deposited metal on the ceramic element is damaged, replace the
ceramic element.
-
Re-assemble in the reverse order.
