Key Features

Blue Diamond® Glass Lining
Blue Diamond® technology increases the life of the inner tank. The lining is stronger and more corrosion resistant than any other in the industry
Glass Coated Heating Element
Scale and sediment build-up on the surface of the element can lead to premature failure. A. O. Smith Glass Coating helps to prevent scale formation and extends the life of the heating element.
Anode Rod
The tank has an anode rod which has stainless steel core that is designed to protect the tank from corrosive elements. The anode rod uses a special cathodic action to fight these elements and thus prolong the life of the water heater.
Temperature Control Knob
The temperature control knob allows you to set the temperature anywhere between 25ºC to 75ºC.
Thermal Cutout
If the water temperature exceeds the highest preset level, the thermal cut-out cuts off the power supply to assure safety.
Multi-function Safety Valve
The Multi-function safety valve is designed to automatically relieve pressure and discharge water in case the pressure overshoots the preset limits.

Note: A. O. Smith reserves the right to amend or modify the specifications and features at any time, as and when required without any prior notification.

• Select a place to mount water heater vertically with water connection at the bottom
• 3-1/2ft. (approx.) from a 230V electrical outlet with proper grounding.
• at least twice the weight of the water heater when completely filled with water.
• drill 2 holes at least 90mm deep in the wall (Fig. 8 : Step 3). The two holes should be aligned horizontally. The horizontal distance between the 2 holes should be 150mm (Fig. 8 : Step 2).
• hole (Fig. 9 : Step 1).
• Expansion anchor and tighten the Hanging screw by rotating it till it gets fixed steadily (Fig. 9 : Step 2).

  Hot water is dangerous, especially for children aged or the disabled. The water heater allows you to control the temperature of your hot water. Water Ntemperatures over 52°C can cause severe burns instantly or death from scalds. NDo not leave a child or an infirm person in the bath unsupervised.

Connecting Multi-function Safety Valve

Wrap the threaded part of the cold water inlet pipe with Teflon tape in clockwise direction.Connect the Multi-function Safety valve to cold water inlet pipe and rotate it in clockwise direction till it get fixed.Connect one end of the discharge tube to Figure 13 the Multi-function Safety valve and connect the other end to the drain. Note: The Multi-function Safety valve may drip during the usage of the heater. As the water is heated, it expands and tries to flowback through the inlet pipe but is prevented by the presence of the non-return valve. Hence water may drip from the Multi-function Safety valve. Therefore a Discharge tube is given from the valve tip to a nearby drain. To avoid dripping, it is recommended to install non-return valve at a distance of atleast 40 feet away from the inlet of the water heater.

CAUTION

• prevent it from dripping or releasing the excess pressure inside the heater. Failure to do so may result in damage to the water heater and injuries to the user. This will also make the warranty null and void.
• Ensure that the free end of the Discharge tube is placed over a suitable drain and away from the users.
