Important Instructions
Please read operating instructions before using the appliance to ensure
safe and reliable performance.
Do's
1. Before plugging in the socket ensure that the mains voltage complies
with the rated one.
2. The gate valve at the inlet shall be kept open.
3. Make sure that no other appliance(s) is (are) plugged into the same
circuit with heater, as this may overload the circuit.
4. If the main cord of the heater is damaged, authorized service personnel
must only replace it.
Don'ts
1. Do not switch ON the heater till it is completely filled with water.
2. Do not install a pressure reducer valve at the inlet.
3. Safety devices are pre-set and sensitive. Do not temper with them. This
could be hazardous.
5. Do not use outdoors. This product is for household use only.
6. In case of any abnormality during operation, immediately switch OFF
the main power supply and contact the nearest service center.
How to Install
1. Installation shall be done by a qualified plumber / electrician.
2. There should be enough space around the heater for easy installation and
servicing.
3. Make sure that the supporting walls or fixtures are strong enough to
carry the weight of the heater when it is completely filled with water.
4. Fix the water heater in perfectly straight position at a suitable height
from the floor.
5. There should be a minimum space of 50 cm between the heater unit and
roof. This is to ensure that heater can be removed easily when required.
6. The heater should be saved from being damaged by splashing water. For
this keep a minimum distance of 1.8 m between the floor and bottom of
the heater.

Water supply
1. You can connect the water heater directly to the overhead water
supply tank. Do not connect the water heater directly to water lifting
pumps.
2. The water level should not be too low. The minimum height between
the heater and water supply should be at least 2m.
Water connections
 Do not connect the cold and hot water pipelines directly to the heater.
Instead connect them using flexible copper pipes. Never use plastic
tubes especially at the outlet, as it cannot withstand heat over extended
usage. In case of direct pipe connections, tightening of couplings
using wrench can damage the heater unit. Always use control / gate
valves at the inlet and outlet. Ensure that the valve at the inlet is always
open.
How to Use
1. Do not switch ON the power supply before filling the heater with
water.
2. Leave the hot water outlet open and open the inlet valve to allow the heater
unit to be filled with water. When the heater is full the water will start
flowing out from the outlet.

3. Now close the gate valve at the outlet. Always keep the inlet valve
open.
4. Switch ON the power supply. Red neon lamps will glow 'ON' to indicate
that power is ON and water is getting heated.
5. Switch OFF the power supply when the unit is not in use.
Safety Devices
Thermostat
An adjustable bimetallic stem type snap action thermostat with temperature
range between 25 C to 75 C, generally set at 60 C cuts the electric power
supply as soon as the water temperature rises above the set temperature and
restarts automatically when the temperature goes low.
Reset type thermal cutout
It is bimetallic type snap action device set to operate at 90 C. In abnormal
conditions, if the water temperature inside the tank exceeds 90 C or if the
water heater is switched on without water the thermal cut out cuts the
power supply and protects the system.
Fusible Plug
Accidentally if the thermostat and the thermal cutout fails to operate, the
fusible plug melts at around 98 C reducing the water steam pressure
inside the tank.
