High pressure resistance suitable for high rise buildings
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
5 Star Rated (15L / 25L ) energy efficient
High grade ABS material of outer body for better finish and strength
High grade thermostat(VDE mark) and thermal cut out (CE Mark)to cut off
electricity when temperature exceeds set limit
High Density PUF Insulation reduces heat loss and improves energy
efficiency

• 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.
• 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
• In case of new installation of water heater,make sure that before electric supply
is switched on, the water should flow freely from the outlet tap or spout
• Inlet water line should be continuously open when water heater is in use except
when it I being serviced
• It is recommended that the “IN/OUT pipes and heating element be de- scaled at
least once a year. Dilute hydrochloric acid is recommended for scale removal

Capillary type high precision with highest safety UL 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 CE 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.
4in 1-Multi Function Safety Valve (MFV):
The MFV used with this unit is a unique Safety Valve. This has four
functions:
1. Pressure Release Valve (PRV)
2. Non Return Valve (NRV)
3. Drain Device
ELCB - Earthing Leakage Ci rcuit 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.

Water Entering:
After connecting all the pipes, rotate the hot and cold water blending valve in
clockwise direction towards maximum temperature. Then, open the water inlet
pipe. At this time the water will start flowing in the tank.
Cautions:
During operation, please make sure that the Inlet Valve is open before switching on the
Water Heater, till the time it is switched off. The inlet valve can be closed partially to
regulate the flow of water. The Outlet Valve is used to control the flow of heated water.
Please make sure that the tank is filled with water by opening the outlet valve once
before switching on the power.
