IMPORTANT TIPS
DRAIN PIPE
While installing your Water Heater, please ensure that the drain pipe faces downwards.
HARD WATER
In hard water areas, a salt deposit (scale) forms on surfaces in contact with water. This reduces heat
transmission and causes failure of the element. In such areas, the door assembly should be removed
and checked atleast once in a year. The deposits, if any, can be removed by scraping or cleaning the
element with diluted Hydrochloric acid.
PRESSURE RELEASE VALVE (PRV)
The PRV should never be tightened or blocked by any means to prevent it from dripping or releasing
excess pressure inside the water heater. The consequences of such an action may be disastrous.
Pressure release valve if tampered, in any manner, voids the warranty of the water heater. The company
shall not be responsible for any consequences arising out of such tampering.
HIGH PRESSURE AREAS
Your water heater is rated for a maximum pressure of 80N/cm2 (120 PSI) or 20 meters (66 ft) of water
head. If the water pressure is more than the rated pressure, a pressure reducer should be fitted to reduce
the pressure below 2.0kg/sq.cm (28 PSI).
WATER PRESSURE
The bottom of the overhead tank should be at least 1.0 m from the top of the water heater. Use a 25
mm pipe for the cold water line with minimum bends. An air vent should be provided near the overhead
tank to avoid airlock.
INLET VALVE
Never close the inlet stop valve during the use of the unit
AUTOMATIC THERMAL CUT-OUT
Because of the automatic thermostatic control, the storage water heater may be kept on 24 hours. If
the thermostat fails to operate, the thermal cut-out is so set that it will automatically cut off the power
supply when the water heater exceeds a specific temperature or gets dry heated.
FLUSHING OUT / DESEDIMENTATION
To flush out sediments deposited in the tank, periodically drain water with the help of the drain plug.
TEMPERATURE SETTINGS
For soft water, we recommend a maximum setting between 60ºC and 65ºC. For hard water areas, a
maximum setting of 50 ºC -55ºC is recommended.
OFF SEASON
For off season discontinuation, remove the drain plug and drain out the water from the heater.
Security Valve
This electric water heater has a single-directional safety valve. It must be installed at the water inlet.
When the tanks pressure is over 0.8 MPa (For Glass line tank) & 0.6 MPa (For Stainless steel tank)
Geyser. This valve will automatically release the pressure to protect the water heater against high inlet
water pressure (mostly installed in High rise buildings)
