An A. O. Smith Glass Coated Element helps to prevent scale formation on the element reducing your electricity bill and extending the life of the element. GLASS COATED ELECIENT Blue Diamond Glass Lining offers the best protection against tank corrosion The new Blue Diamond technology with enhanced levels of zircon increases the life of the water heater. The lining is proven to be stronger and more water-resistant than any other in the industry. BLUE DLAINONDT GLASS UNING Anode Rod protects the tank from corrosion The tank has an anode rod system with a stainless-core that is designed to protect the tank from corrosive elements. The system uses a special cathodic action to fight the corrosive elements which in turn prolongs the life of the water heater. ANODE ROD PROTECTION Safety Valve discharges water in case pressure or temperature exceeds preset limits This water heater has a temperature and pressure safety valve. This valve is designed to automatically relieve and discharge water incase the pressure or temperature overshoots the preset limits. SAFETY VALYE Thermal Cutout cuts off live line and zero line, in case of fault, ensuring safety The breaker rapidly cuts off live line and zero line simultaneously to guarantee safety, in case the water heater happens to be faulty and water temperature exceeds the highest temperature preset in the thermostat. THERMAL CUTOUT 3 Installation Mounting - 120 -90 S 13 111111 Illllll 5 *** 2 - Wall * * * 1 Make sure that the wall can withstand at least twice the weight of water heater when completely filled with water. 2 Before locating the position for installation, make sure that there is a clearance of no less than 300 mm between the front of the heater and the wall. This allows easy opening of the decorative front panel for maintenance or to reset the thermal cutout when necessary. 3 Use a drill bit with diameter of 10mm to drill 4 holes at least 90mm deep in the wall. The four holes should be aligned horizontally and vertically. The horizontal distance between the 2 holes should be 120mm and the vertical distance should be 57mm as shown in the above diagram. 4. Insert the expansion anchors into the holes. Place the wall bracket over the expansion anchors and screw the four screws tight against the bracket. 5 Hang the water heater using the hanger hooks on the wall, through the 4 holes on its mounting bracket. Move the water heater downward to ensure that the holes are pressed against the root of the hanger hooks and ensure the water heater is fixed steadily. Plumbing 1 Make necessary plumbing with reference to the installation diagram on the right page. 2 Connect the safety valve in the water inlet [blue]. It must be installed at the side of the inlet pipe. It has been factory set at 0.8 MPa and is not adjustable. The discharge tube of this valve must face downward and the discharged water must be piped up to or within 15cm above a suitable drain. Under any circumstances, the drain line cannot be blocked and must be open to atmosphere. Attention: The direction of arrow points to the water heater that indicates the direction of the water flow current. 3 Connect the hot water pipe to the outlet [red]. Attention: Make sure a suitable sealing tape is used for all connections to prevent leakage. Meanwhile, the safety valve must not be screwed too tight to prevent damage. Electrical Connections The power cord and plug are connected with this water heater. Find a separate socket for power plug and make sure the socket is in contact with the plug. Filling Water ACSmith 1 Open a hot water faucet nearby to permit the air to escape. 2 Open the cold-water inlet valve fully, filling the heater and the piping. 3 Close the hot-water faucet when water flows. 4. Check all the connections to see if there is any leak. In case of a leak, drain the heater completely, repair the leaking joint and then refill the heater Hot Water outlet Safety Valve Lever Tube Cold Water Inlet Mixing Valve Mixing Water Floor Drain Operation Instructions 1 Switch on the water heater's power supply. The yellow indicator light comes on. 2 Turn the thermostat knob clockwise for the device to commence heating and change the set temperature. A red light will come on. The set temperature increases if the thermostat knob is turned clockwise. Temperature can be set in the range of 25°C to 75°C. 3 The red light's switching off indicates the heater has been heated to the set temperature. Maintenance and Cleaning Check proper functioning of the safety valve every two months by opening and closing the test lever. The heating element should be checked annually for scale formation, caused by impurities in the water supply. Also, the anode should be checked annually and replaced when worn out over 60%. For cleaning the element or replacing the anode use the following procedure: 1 Switch off the electric supply to the water heater. 2 Open the hot water taps until the water is not hot any more. 3 Close cold water supply. A 4 Drain the water heater by removing the safety valve in the direction of the arrow as indicated in the diagram shown along side and open the hot water taps. 5 6 7 Take off the water heater from the hanger hook, when the water heater is empty. Remove the decorative front panel, unscrew the heating assembly flange. Clean the container and the heating element assembly from scale by using a suitable acid or by gently scraping the scale. 8 Replace anode if required. 9 Remount the heating assembly flange. 10 Hang the water heater on the hanger hook on the wall through the 2 holes of its mounting bracket. Move the water heater downward to ensure that the holes are pressed against the root of the hanger hooks and ensure the water heater is fixed steadily. 11 Open cold water supply until water flows without interruption from hot water faucets. 12 Close the hot water taps and check for eventual leakage around the flange. 13 When there is no leakage, replace the decorative front panel. Then switch on electric supply.
