Safety Devices :

Havells Water Heater is built-in with a host of Safety Devices to ensure your safety at all times. The operation of these devices are
described below :
A. Thermostat
Capillary type thermostat: This device "cut-off" and "cut-in" the power supply between a narrow band of temperature range.
The indicator lamp provided with this circuit glow and un-glow during cut-in and cut-off. This shows the proper working
thermostat. This device is provided with an adjustable knob to set the desired water temperature.
B. Thermal Cutout
A non-self resetting thermal cutout is provided as a safety device. When the thermostat fails to function, this cut-off the
at 90°C.
The thermal cutout has to be manually reset before the heater can start operating again.
C. Earth Leakage Circuit Breaker (ELCB)
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 press reset button to restore normal functioning of the heater. It is advisable to periodically
repeat this test to verify the functioning of the ELCB.

Multifunctional Safety Valve (MFV) :

1. Pressure Release Valve ( PRV)
2. Non return Valve ( NRV)
3. Vacuum Release Valve ( VRV)
4. Drain Device
Adjustable Temp. Knob with Thermostat :
Allows a manual setting for heating of water between ambient temperature to 75°C.
4 Bolt Flange :
Provides an easier way for product maintenance.
Ensure high level of protection to electrical parts from water splashing.
