INSTALLATION OF SENSORS
On the upper side of the storage tank there are two sensor tubes for mounting the sensors for regulation of the system connection
of the hot water storage tank to other heating sources. The maximum diameter of the sensors is 8 mm.

must be removed. This is done by pulling out the knob on the
thermostat axis and unscrewing two screws.
An all-pole disconnect device must be installed in the electric
installation to comply with the National Installation Regulations.
USE AND MAINTENANCE
The hot water storage tank is ready for use once it has been connected to water and electricity and other heating sources. The
usual main sources for heating domestic water are central heating or solar power; in this case any regulation of water heating is
performed in the heating system.
The built-in electric heater is intended for additional water heating only and can be controlled by an external unit.
In case of exposure to sub-zero temperatures, the water should be drained from the storage tank thoroughly before the onset of
freezing conditions. Water from the storage tank is drained through the inlet pipe of the storage tank. For this purpose, a special
fitting (T-fitting) with an outlet valve must be mounted between the safety valve and the inlet pipe. Before discharge make sure the
storage tank is disconnected from the power supply, close the inlet of cold water into the storage tank, open the hot water tap on
the connected mixer tap and wait for the water in the storage tank to cool down. After discharging through the inlet pipe there is
still some water left in the storage tank.
The external parts of the water heater may be cleaned with a soft cloth and mild cleaning fluids. Do not use cleaning fluids
containing alcohol or abrasives.
Regular preventive maintenance inspections ensure faultless performance and long life of your storage tank. Tank Warranty is
subject to regular inspections of the wear of the protective anode. The period between individual regular inspections should not be
longer than specified in the Guarantee statement. Inspection should be carried out by an authorised maintenance service provider
recording the inspection on the Guarantee Certificate of the product. During the inspection, the wear of the corrosion protection
anode will be inspected and any limestone built up in the interior of the storage tank, depending on the quality, quantity and
temperature of used water, will be removed as required. After inspecting the storage tank, the maintenance service provider will
also recommend the date of the next inspection according to the ascertained status.
