Incoloy 800 Coated Heating Element:
Incoloy 800 Coated Heating Element offers superior heating
performance with its excellent resistance to both oxidation &
carbonization at high temp. setting. Also resists erosion against most
extreme and hard water conditions thus extending life span of heating
element with minimum energy loss
Heavy duty Magnesium Anode Rod to prevent rust and corrosion:
Magnesium Anode Rod protects enamelled tank from rust and
corrosion. Also enhances life of tank and element even with the usage
of hard water
4 Star Rated (35L) / 3 Star Rated (50L) energy efficient
Blue Sapphire enamel coating on tank to prevent from rust and corrosion
External Temperature control knob
High Density PUF Insulation reduces heat loss and improves energy
efficiency

Safety Features General Maintenance
Capillary type high precision Thermostat with highest safety VDE Mark:
“Cut-off” and “Cut-in” functions regulate the power supply between a
narrow band of temperature range. Functioning of indicator lamps
during ‘cut-off’ and ‘cut-in’ indicates proper working of thermostat. This
device is provided with an adjustable knob to set the desired water
temperature.
Preset Thermal Cut out with VDE mark:
A non-self resetting thermal cutout is provided as a safety device.
When the thermostat fails to function, this cut-off the power at 900C. The
thermal cutout has to be manually reset before the heater can start
operating again.
Multi function Safety Valve (MFV):
The MFV used with this unit is a unique Safety Valve. This has three
functions:
1. Pressure Release Valve (PRV)
2. Non Return Valve (NRV)
3. Drain Device
ELCB - Earthing Leakage Circuit Breaker:
This water heater is equipped with an Earth Leakage Circuit Breaker
(ELCB) which will cut-off the power immediately in case of any current
leakage. This will ensure protection against electric shock in case of
current leakage. In order to ensure that the ELCB is working normally,
press the ‘Testing’ button on the Device. If ELCB cuts off the power to
the heater, it means that it is working properly. After testing, please
reset button to restore normal functioning of the heater. It is advisable
to periodically repeat this test to verify the functioning of the ELCB.
16 Amp Power Plug
• Check frequently if the connection of power source plug and the outlet is in good
condition. The plug’s outlet is well connected to the ground or not.
• Clean the heating parts once in a year in order to assure high efficiency of storage
water heater.
Caution and Installation Instructions
• Do not install the Electric water heater without Multifunctional Valve.
• Before installing the Electric Water Heater check the water pressure of the Inlet
connection. If it is more than the rated pressure, install pressure reducer valve
before connecting with the Inlet of Heater.
• Usha strongly recommends use of ELCB
• It is Strongly recommended to use flexible pipes at inlet and outlet points
• Do not tamper with the settings of Multi functional Valve.
• To have longer life of Heating Element, ensure the water hardness should not be
more than 100TDS
• Please ensure Water Heater is mounted on solid cement walls and installed 200M
above the ground
