Key Features

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.

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.

Safety Valve

The safety valve is designed to automatically relieve and discharge water, in case

the pressure overshoots the preset limits.

Dual Glass Coated Heating Elements

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 elements. Dual element helps in quick

water heating.

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.

Remote Controls

The LED displays set temperature, actual temperature, timer, clock, etc. The user

can select the set temperature within the range of 35°C to 75°C. It is easy to

operate the water heater with wired remote control even if the water heater is

placed in an enclosed area.

Do not install the water heater where there is

direct sunlight or rain. It is has to be installed

indoor only.
