Страница: 3 / 6

THERMOSTAT AND THERMAL CUTOUT :
Your instant water heater is provided with Capillary type thermostat and
Disc Thermal Cut-out.The device cuts off electricity supply when
temperature rises above 85 degrees.
FUSIBLE PLUG:
There is a fusible plug provided in the water heater which melts if the
temperature of the water heater exceeds the safety limits due to any
reason. In addition, melting of the fusible plug drains the hot water while
simultaneously drawing in cold water thereby allowing the water
temperature to reach a safety level. Contact the service centre
immediately.
PRESSURE RELEASE VALVE:
The instant water heater is provided with a pressure release valve to
release excess pressure inside the tank in case it crosses the specified
limit as per ISI norms.
ISI MARK:
This Water Heaters are ISI approved.
1. Your Usha Instant Water Heater is made of non-corrosive ABS plastic
body, copper heating element and SS tank along with safety devices
like thermostat, thermal cut out, fusible plug, pressure release valve.
2. Water enters into the inner tank through the inlet pipe at a normal
working pressure.
3. When the tank is full, the water will flow through the outlet. Switch the
power supply ON. The green lamp will light up.
4. Water flow can be controlled to control the water temperature. With a
greater rate of flow, the temperature of the water drawn is lower and
vice versa.

INSTALLATION GUIDELINES SAFETY FEATURES
Place the installation template (provided with this manual) in a vertical
position on the wall wherever you need to fix the water heater on the
wall.
Taking reference from the markings on this template, drill suitable holes
in the wall.
Plug these holes with wooden or plastic pegs (rawl plugs) and fix the
screws very firmly into them.
Provide an electric power supply connection to the unit using a D.P
switch, properly earthed.
Please ensure that the pressure in the water heater is less than the
rated pressure. If it is more than rated pressure, install pressure
reducing valve at the inlet.
Check for water line blockages. Ensure proper water flow.
Connect the inlet of the unit to the incoming water supply line with only
flexible tubing.
The cold and hot water pipes should not be directly connected to the
heater unit – flexible connector tubes are required to prevent damage
to the unit when tightening the couplings with a wrench.
Ensure flow of water from outlet before connecting electric power
supply to the appliance.
Do not use excessive force while tightening inlet and outlet couplings.
This may cause serious damage to the water heater. Use cross
spanner for tightening.
Do not tamper with the Pressure Release Valve settings.
It is strongly recommended to use ELCB.
Check supply voltage at the place of installation.
No extension cord to be used.
Ensure all couplings/joints are leak-proof.
Check the water heater operation for one complete cycle i.e. one cycle
of Thermostat operation, i.e. Cut-off and cut-in.
5. The heating element heats up the water to a predefined temperature.
At this point, the Green light will turn OFF and thermostat automatically
switches OFF the power supply to the unit. As the temperature of water
inside the tank drops the thermostat again switches ON the power to
the heater and the Green light will turn ON. This process continues till
you switch OFF the main power supply to the heater after usage.
6. In the rare case of the thermostat failing to operate, the thermal cut out
operates at 85 degree Celsius and switches OFF the power supply.
The Red lamp will light up in case of this event contact nearest
authorized service centre or customer care centre.
