• If the mains cable is damaged, it must be replaced in order to avoid any
danger. Such replacement must be performed by the manufacturer, its
service support or a similarly qualified professional.
• The first heating cycle must be supervised by a professional.
• The electrical safety cover may not be removed, but by a professional;
failure to observe this may lead to electrical shock or other dangers.
• To ensure safe operation it is recommended to regularly (every year)
have the appliance and the combined safety valve checked by a qualified
professional for proper operation. Additionally, it is also recommended
to blow off the valve every two months by turning the blow off button of
the safety valve in the direction indicated by the arrow. This way, the
valve seat will be cleaned of any possible deposit (scale, sand grains
etc.).

PRINCIPLE OF OPERATION

This closed-system hot water tank can supply hot water to multiple water
withdrawing locations in households or institutions.
The hot water obtained is suitable for both cleaning and drinking purposes.
However, having regard to the fact that hot water has a higher capacity to dissolve
metals, it is recommended to use cold water for cooking and drinking, and consume
it after heating, when hot water is needed.
Before starting its use, fill the hot water tank with drinking water for one day, and
drain the rinsing water in the sewage network. Do not use the rinsing water for
household purposes. The proper use of the system may not be started, but after the
steps above.
Perform mechanical cleaning only; no other cleaning or disinfection is needed.
The temperature regulator turns off heating when the temperature of the water in
the tank reaches the preset value, and keeps it turned off until the water
temperature falls app. 3-4 °C below such value.
The polyurethane heat insulation surrounding the inner tank prevents the fast
cooling of the water, thus ensuring the availability of hot water from the container
over a long time. Due to the design of the container, hot water is discharged
unmixed.
The inner tank is made of corrosion-resistant steel. In addition to the special enamel
coating, the steel plate is also protected by an active anode against corrosion. The
enamelled design ensures long service life, even in the case of aggressive (soft)
water.
