8 - Maintenance, Replacement of Magnesi-
um Anode Rod
If the tank is fitted with a heating element, disconnect it from the mains first. Clean the exterior of the tank with
a soft cloth and a mild detergent. Never use abrasive cleaners or solvents.
Check all connections for leaks.
The tanks are equipped with an anti-corrosion sacrifice magnesium anode rod. The anode rod shall be chec-
ked within 12 months after commissioning and subsequently always not later than 12 months after the last
check. In locations where water contains more ferrites or calcites, it is recommended to check the anode every
6 months. If more than 1/3 of its total volume is consumed, the anode shall be replaced with a new one. Dis-
regarded of its state, the anode rod shall be replaced with a new one within 24 months from commissioning.
In case an electronic anode is used, the above described procedures are not necessary. Then only a visual
check of the indication lamp is necessary every 3 months.
Proper working of the Electronic Anode is described in its User’s Manual.
If damage to a tank occurs due to neglected substitution of a magnesium anode rod or a non-working electro-
nic anode, warranty cannot be claimed.
9 - Disposal
Packing shall be disposed of in compliance with the valid rules. When the product reaches the end of its life, it
shall not be disposed of as household waste. It shall be dropped off at a Local Waste Recycling Center. Insu-
lation shall be recycled as plastic and the steel vessel as scrap iron.
10 - Warranty
This product is covered by warranty according to the conditions described in this Manual and according to the
Warranty Certificate. A Warranty Certificate is an integral part of the supply. Tank transport or storing in a hori-
zontal position is considered a warranty violation!
11 - Recommended Accessories
11.1 Expansion vessels for storage water heaters
The inner surface of R2BC hot water tanks as well as the heating coils are enameled. In order to compens-
ate for fluctuations in temperature and pressure, and avoid damage to the enameled surface, installation of
a properly sized expansion vessel is necessary. This vessel also saves water escaping through a safety valve
during warm-up. A calculation of the expansion vessel volume shall be included in the heating design. The
volumes of expansion vessels in the table are informative only. Working pressure 2-8 bar and domestic water
temperature inside the tank 10-70 °C are presumed. For tanks of bigger volumes, use of an expansion auto-
mat is recommended.
