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.
Temperature Control Knob
The temperature control knob allows you to set the temperature precisely
between 25ºC and 75ºC. Only for HSE-SBS-006 & 010 Litres models.
Remote Control
Displays the temperature and the total energy consumed by the water heater.
Temperature can be precisely set between 25ºC and 75ºC. It is easy to
operate the water heater with remote control even if it is placed in an
enclosed area by connecting with an approximately 8 feet wire.
Only for HSE-SBS-015 & 025 Litres models.
Safety Valve
The safety valve is designed to automatically relieve pressure and discharge
water, in case the pressure overshoots the preset limits.
Thermal Cutout
If the water temperature exceeds the highest preset level, the thermal cutout
cuts off the power supply to assure safety.
Glass Coated Heating Element
Scale and sediment build-up on the surface of the element can lead to prema-
ture 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.
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.

Do not install the water heater where there is
direct sunlight or rain. It is has to be installed
indoor only.
