DE-SCALING INSTRUCTIONS
As an
optional extra
, the generator can be fitted with a Descaling Kit, to facilitate the addition of
citric acid solution into the tank. De-scaling of HSS M and HST M steamers is carried out by
installing the pipe with filler in line between the generator and pressure release valve. (see
illustration)
Remove parts from packaging. Unscrew pressure release valve from generator and attach filler pipe
using PTFE tape provided to ensure a good seal. Use only Citric Acid recommended by Saunatec,
to ensure the process poses no health risks.
This is how you de-scale using citric acid
1. Add 50g (one bag) of citric acid to approx. 1 litre of water and mix well. Let it dissolve into
the water.
2. Lift the plastic protective cover from the generator and open the filling pipe tap.
3. Pour the liquid into the steamer's tank using a suitable funnel and close the tap.
4. Start the generator normally and let the water boil for about 10 minutes. Then stop the
generator and continue depending on whether the generator has been fitted with an automatic or
a manual flushing valve:
•
Automatic flushing valve:
The generator will empty and rinse itself after 15
minutes of idle time. After the first flush, generator is started again and water is
allowed to fill the tank. The generator is stopped again and it will flush and rinse
after 15 minutes. This can be repeated about 3 - 5 times.
•
Manual flush valve:
After boiling, let the citric acid work in the tank for about 15
minutes and empty the tank by opening the flush valve. Close the valve after the tank
is empty, start the generator again and let the water fill the tank. Stop and empty the
generator again. Repeat 3 - 5 times.
The generator is ready for use straight after de-scaling. If the steam room is filled with a citric
scent after treatment, rinse the generator again. Use of citric acid is not harmful to health.
STEAMERS IN PROFESSIONAL USE
In addition to de-scaling treatment, a further service plan is recommended if the generator is in daily
use (5 or more hours). Servicing is recommended at least twice a year so that elements, water level
sensor and the tank will be checked internally for lime-scale build-up. Parts damaged by scale
should be replaced. The tank may be cleaned following removal of the elements.
