Instructions for Use and Installation HNS-M / HLS
Decalcification instructions
Decalcification procedure for the HNS-M steamer is very easy. By using the citric acid recommended by Helo, the
procedure is safe.
HNS-M steamer's lid is equipped with a filling tube for deliming agent, which makes it easy to add the agent into the
tank.
HLS steamer must be equipped with a separate Descale Kit to get the agent into the tank. Descale Kit is installed on
the steam pipe before the relief valve.
How to decalcify
-
Add 50g citric acid (one bag) to 1 litre water and mix, let the agent dissolve into the water.
-
Lift the plastic cover off the steamer and open the filling pipe cap.
-
Pour the solution into the tank (use a funnel, if necessary) and close the cap.
-
Start the steamer as usual and let the water boil for about 10 minutes. After the water has boiled enough, stop
the steamer and follow these instructions:

The steamer is ready to be used right after the calcification treatment. If there is a lemon scent in the steam
room after the treatment, rinse the steamer again. Use of citric acid is not hazardous to health.
Steam generator in professional use
In addition to decalcification treatment, it is recommended to make a service plan for steam generators in daily use (6
hours or more). Service is recommended to be done 6 times a year and it is to include visual inspection of the heating
elements and the surface sensor, inspection and cleaning (lime accumulation) of the inner surface of the tank, and
replacing components, if necessary. Tank cleaning is done through the heating element mounting holes.

Automatic flush valve: The steamer flushes and rinses itself 15 minutes after it has been
stopped. After the first flushing the steamer is restarted and the tank is allowed to fill up with
water, after which the steamer is stopped again and allowed to flush and rinse again after
15 minutes.
This can be repeated about 3 to 5 times.
If HSX – L is equipped with an automatic flush valve, install the manual flush valve found in
the original packaging temporarily in the unit and rinse the unit according to the manual
flushing instructions.
Manual flush valve:: After boiling, let the citric acid solution act in the tank for 15 minutes
and flush the tank after that by opening the flush valve. Close the valve after the first flush-
ing and restart the steamer and allow the tank to fill up with water. Stop and flush the stea-
mer again, and repeat this about 3 to 5 times.
