2. OPERATION

The hot water tank with closed internal circulation system performs hot water supply for several water connection points in
household and in institutions.
The hot water provided by the unit can be used for washing and eating purposes.
The water has drinking water quality if it complies with limit values as defined in Government Decree of the Republic of
Hungary No. 201/2001. (X.25). The temperature of the water stored in the unit can be set according to your needs, up to
65 or 80 ºC. After reaching this temperature, the temperature controller switches off heating automatically. This way, the
water tank supplies hot water for a long time. The polyurethane insulation covering the internal tank impedes rapid
cooling down of the water, this way, the water tank supplies hot water for a long time. The storage structure ensures that
hot water outflows without mixing.
The internal tank is made of anti-corroding steel plate. Besides a specially fired enamel coating, an active anode also
protects the steel plate against corrosion.
The specially fired enamel design provides long life in case of aggressive (soft) water. The main outline dimensions of the
water storage are described in Figure 1
3. STORAGE INSTALLATION / DEPLOYMENT
Pursuant to regulations of Hungarian Standards IEC 60364 / HD 60364, the hot water storage must be installed and
connected to pipeline and electricity by a professional technician.
Before installation of the unit, a professional architect has to analyze the structure of the wall where the unit will be
mounted.
The following solutions are proposed in case of different wall types:
• Stone, brick and concrete walls of thickness of 100-150 mm: hex head bolts (Hungarian Standard M 12, EN ISO
4017), bolt washer for wood connection (M 12). It is mounted with horizontal flat steel of 50 x 5 at the back side of the
wall.
• Really thin walls: hex head bolts (Hungarian Standard M 12, (EN ISO 4017), bolt washer for wood connection (M
12). Fixed with 2 U shaped steels of 60 x 40 x 3 (EN 10279) vertically at the back side of the wall.
4. PIPELINE CONNECTION
Any steel pipe, plastic pipe and red copper pipe or flexible pipe connection adequate to a water pressure rated as 0.6
MPa can be used as hot or cold water pipes.
In case of connecting red copper pipes to the pipeline system, the use of insulating intermediate pieces is compulsory.
One of the intermediate pieces has to be mounted directly to the hot water pipe of the water tank, while another
intermediate piece has to be mounted between the already fixed fittings and the red copper pipeline system. In case of
connection without intermediate pieces, our Company undertakes no guarantee for defects due to corrosion of internally
threaded pipe ends of the water tank, neither any liability resulting from or related to such events. The middle piece not
accessory.
Can be ordered: 1/2" Article Nr.1252122514
The water tank should be connected to the pipeline system according to Figure 2.
IT IS AT THE RISK OF DEATH AND THEREFORE IT IS FORBIDDEN TO PUT THE WATER TANK UNDER A
PRESSURE LARGER THAN THE PERMITTED OPERATION PRESSURE!
4.1 The combined safety valve is an accessory of the water tank. Its connection to the hot water tank and to the pipeline
system: Rp1/2 internally threaded.
The valve has to be mounted DIRECTLY in front of the water tank into the cold water pipe, respecting the flow direction
marked by an arrow. Before mounting the valve, the cold water pipeline has to be flushed thoroughly, in order to avoid
any damage caused by any possible pollution.
The outlet tube has to be placed vertically downwards and the blow-off button has to be accessible. In the order of water
flow, it contains the one-way valve, the security valve and the outlet tube that has to be left open toward the air space.
4.2 If the water pressure in the system exceeds the value of 0.6 MPa temporarily, a pressure reducing valve has to be
mounted in front of the hot water tank. This pressure reducing valve has to be purchased and mounted by the customer.
The pressure reducing valve has to be mounted in front of the combined safety valve.
4.3 An arbitrary number of taps and mixing faucets can be mounted on the hot water tank. The flow back of the hot water
through the outlet towards the pipeline system is blocked by the one-way valve, which is not an accessory of the hot
water tank.
