System Elements
Safety Valve : In case of high pressure in the boiler it discharges the water. Expansion Tank : It adjusts pressure fluctuations that can occur within the system. Check Valve : It allows fluid moving within the system in the desired direction and blocks the fluid flow to the opposite direction. Filter : It is used to remove impurities from the water circulating in the system. Valve : It is used as an installation element that allows or stops the flow of water into system. Pump : It enables the circulation of fluid used in the system. Manometer : It is used to measure the pressure inside the system. Thermometer : It is used to measure the temperature of the liquid in the system. Pressure Reducer : In case the water pressure in the system exceeds the optimal allowable pressure of the device a pressure reducer must be installed on the connection line to automatically discharge water in the system until pressure is normalized.

Device Settlement and Installation Guide
• Products will be delivered with wooden pallet. Before the installation the wooden should be removed. • The installation should be performed according to the Flow Diagrams in this document. • The device should be placed on a suitable base with smooth and strong surfaces to support the weight of the boiler. • The user should choose the area of installation according to maintenance requirements. • The device should be placed indoors or in an area where there is no danger of freezing. • In order to make the device work effectively, the system to which the water heater is connected should be according to schemes. Heating resources should be chosen according to hot water supply needs. • If the installation guidelines are not followed or if damages occur during the installation process the product will be out of warranty. • If the automatic safety valve is not assembled or if it is is incorrectly installed then the product will be out of warranty. • The place of installation should be protected against fires and floods. The warranty does not cover any product failure caused by external system elements.

THE MOST IMPORTANT POINT WHEN INSTALLING A WATER HEATER IS NOT TO FORGET TO INSTALL THE SAFETY VALVE Water expands when heated. The expansion rate with temperature is illustrated at the table and plot below. For example, water expands 1.19% at 50 oC. This extra volume of water should be removed from the water heater. Water is an incompressible liquid. If the expanded water is not removed from the water heater then there will increased pressure on the product body which can cause damages on the weakest point of the water heater. d (kg/lt) 0.9998 0.9996 0.9982 0.9956 0.9922 0.9880 0.9832 0.9777 0.9718 0.9635 0.9583 0.9519 0.9431

Expansion Tank Application The expansion tank used in the system should have at least 10% of the volume of the water heater, capable of work under 10 bar pressure and initial pressure should be set to 10 bar. The most important feature in the system is to use safety valve and expansion tank. Always install the expansion tank and the safety valve between the water heater and the valve.

Before Activating
• The domestic hot water circulating in the system should be according to the quality standards defined in the last page of this document. The warranty does not cover the cases where the domestic hot water does not meet these standards. • Verify the mechanical and electrical connections of the product. • Check for leakages in all connections and pipes. • The electric resistances should be grounded. When you are working on the connections of the system please turn off electricity. Activating • Please do not start to operate your water heater before you make sure that it is filled with water and that the cold water inlet is available. • After completely filling the water heater, in order to release remaining air in the product please open the hot water tap. • Electric connections of the device must be done by a qualified electrician. • Check the cable section, voltage and grounding line and then set the safety thermostat in the control panel. • Do not turn on the electric resistance before completely filling the water heaters.

Periodic Maintenance and Cleaning
• It is suggested to clean inside the water heater through the cleaning flange in order to remove dirt particles that may exist in the water system. • If the product is with electrical instruments please disable the electrical connections. • The gaskets used on the products are only suitable for one usage. In case they are removed for any reason they should be replaced and you should contact the seller. • Please be sure that the elements like valve, check valve, strainer, security valve, expansion tank and thermometer are in good condition. • Please remove and clean the filter of the strainer periodically • The magnesium anode rod should be checked every year. The substitution frequency can be determined after the first control. The quality of the water is important for the life of the anode. • If the magnesium anode rod diameter is less than 12mm it should be changed. (Original diameter is 26mm) • The magnesium anode rod is out of the warranty. • When the water heater is deactivated please be sure that the tank is empty to prevent possible freezing problems. • When cleaning the interior of the product please be sure that you do not damage the enamel inside. • After cleaning the interior of the product please be sure that cleaning flange, thermowell (sensor) and thermostat are safe and there is no leakage.
