Damage to equipment can be caused by:
• external forces;
• corrosion;
• chemical action;
• erosion;
• material exhaustion;
• water hammer;
• thermal and/or mechanical shock;
• freezing;
• wrong transport/lifting.
If a danger of frost occurs, the tank and the coil(s) should be drained completely.
Sudden pressure and temperature changes should be prevented.
Even after stopping the installation some parts of it can still be hot! Therefore, it must be allowed to
cool down to intervene.
If welding activities have to be carried out near the equipment, never use the tank for earthing.
Electric currents can cause severe damage to product.
If you have to weld, dismantle the connections and isolate the equipment from the system.
When a tank (filled with water or water mixture) which is not in operation is exposed to
temperatures below zero, the tank can be damaged.
The water heater coils are only suitable for hot water or water-glycol mixtures in the liquid
phase. In the coils, steam and superheated water cannot be used as heating medium.
Potable water with a hardness of 20 Fr and above should not be used in a storage water heater
without reducing its hardness. Otherwise, lime deposits formed on hot coil surfaces both reduce
the equipment's heating capacity by preventing heat transfer and may cause perforation on the
overheated coil surfaces due to corrosion.
The chemical and physical nature of the water to be heated and stored in the tank must comply
with the limit values specified in the Council directive 98/83/EC of 3 November 1998 on the quality
of water intended for human consumption.
We reserve the right to make changes in technical information.
