free performance.
II. PRECAUTIONS DURING INSTALLATION:
1. Do not switch on the heater without water inside.
2. Do not close the inlet Control valve ever, except when servicing the
Heater.
3. Do not plug the opening of the MFV ever.
4. Ensure the maximum height of the over head tank from the heater does
not exceed the prescribed values as given. If the height is more, use a
pressure reducer valve to reduce the pressure accordingly.
5. Connect the water heater to an automatic pump only after referring the
instructions given in page no.4, point no.7.
6. Ensure the heater is properly earthed.
III. INSTALLATION :
To install the water heater, you need the following tools and accessories.
(Not provided along with the heater)
1. One No.23mm, one No.26mm and one No.27mm double end spanners.
2 Drilling machine with 8mm to 12mm drill bit.
3. Two no of exible hose (ISI Certied)
4. Star screw driver .
A. Fixing to the wall :
1. The heater should be xed to the wall only in the vertical position with the
inlet and outlet pipes facing downwards.
2. Fix the wall plate provided with the heater on the wall using the screws
and nylon plugs.
a. First drill 3 holes on the wall for 55mm depth synchronizing with
those on the wall plate.
b. Insert the Nylon plugs in the holes.
Fig : 1
3
GLASS LINED
WATER HEATER
c. Fix the wall plate by inserting the screw into the nylon plug and tight-
ening it till the wall plate is rmly held.
d. The heater can now be hang on to the wall plate by the hanger.
3. Leave a minimum clearance of 25mm between the heater and the ceiling
to facilitate removal of the heater from the clamps if necessary.
4. The bottom of the heater should be about 1.8 m or more from the ground
to avoid splashing of water on to the heater.
B. Water supply connection :
1. Connect the water heater to the cold water line from the over head tank or
from the mains.
2. Do not connect the cold water mains to the heater directly if the mains
pressure exceeds the rated pressure of the water heater. In this case a pres-
sure reducer valve is to be provided.
3. Fix a control valve at the inlet to the heater. Ensure that this is a gate valve
or angle valve that opens and closes positively when operated.
4. Connect cold and hot water pipes by exible tubes like (a) Chromium plat-
ed Copper Tubes, or (b) Heavy duty exible PVC tubes.
5. Heater inlet (cold) and outlet (hot) pipes are marked “ IN” and “OUT” on the
inspection cover.
6. The heater can be connected to multiple outlets - shower, wash basin, bath
tub etc., Fig.2 shows the schematic layout of multiple outlet connections.
Fig : 2 Heater Outlet Arrangement

GLASS LINED
WATER HEATER
7. Connection to Automatic Pressure Pump
The heater can be connected to an automatic pump system also, provided the line
pressure does not exceed the rated pressure as given in the name plate sticker of the
water heater.
On connecting an automatic pump to the water heater, the Multi Function
Valve(MFV) may drip during the usage of the heater. As the water is heated,
it expands and tries to owback through the inlet-pipe but is prevented by
the presence of the automatic pump. Hence water may drip from MFV. If the
dripping is slow and intermittent, provide a thin tube from the valve tip to a
nearby drain. If it is steady and excessive, call our mechanic. Never try to adjust
the MFV setting, as this will damage the heater.
Important :
The MFV should never be removed or blocked by any means to
prevent it from dripping or releasing the excess pressure inside
the heater. The consequences of such an action may well be
disastrous. MFV if tampered, in any manner cancels the war-
ranty of the heater.
8. Connection in high pressure areas
a. The rated pressure of the heater is mentioned on the name plate
sticker.
b. If the water pressure is more than the pressure rating, a pressure
reducer valve should be tted to reduce the pressure accordingly.
c. The output of the pressure reducer valve should be less than or equal
to the rated pressure of the water heater.
9. Connection in low pressure areas :
The water pressure should not be very low. The bottom of the overhead tank
should be atleast 1.0m from the top of the heater. Also, use 25 mm pipe for cold
water line with minimum of bends. An air vent should be provided near the
over head tank to avoid air lock.
WARNING
Do not t a non-return valve or check valve at the inlet.
A non-return valve prevents expansion of hot water inside the container. This
will lead to increase in pressure inside the container till the safety pressure
release valve opens. This will happen in each heating cycle and is not desirable.
So, a non-return valve should not be tted.
Note: Do not use an ordinary stop cock which also acts as a non-return valve.
C. Electrical Connections
1. All internal connections are made in the factory itself.
2. Use a 16Amps 3pin plug and preferably a 30Amps Double pole (D.P).

Switch. Connect Red wire to Phase, Black wire to Neutral and Green wire
to earth terminal of the plug. A separate fuse can be provided as an addi-
tional safety feature.
IV. OPERATION
A. Using the heater for the rst time :
1. Do not switch “ON” before lling the heater with water.
2. Leave the hot water tap open. Now ll the heater by opening the control
valve at the inlet.
3. When the heater is full, water will start owing through the hot water tap.
Close the hot water tap.
4. Now the heater will always have water inside. Water drawn will be replaced
by water from the over head tank.
5. ALWAYS KEEP THE INLET CONTROL VALVE OPEN.
6. Now switch “ON” the power supply to the heater.
Fig : 3 Wiring Diagram

GLASS LINED
WATER HEATER
B. Using the heater regularly :
1. Always keep the inlet valve open so that water drawn from the hot wa-
ter tap is automatically replace from the mains.
2. Switch “ON” the Heater. The Red color indicator will glow, indicating that
the heater is working.
3. When the water reaches the required temperature the thermostat will
switch “OFF” the power automatically. The approximate time taken to
switch “OFF” by the thermostat for dierent capacities is give in “Perfor-
mance Table ” on Page no-8
4. In general, assuming a room temperature of 20°C it will take 12hours for
the water temperature to drop from 65°C (Very Hot) to 40°C(Warm)
5. The Thermostat setting may be changed by the user to suit own choice.
Lowering the setting of the thermostat will give a lower hot water tem-
perature increasing the setting will give a higher output temperature.
6. Initially it may take a long time for the water to get hot, So switch “ON” the
water heater at least an hour before you want use it,
7. If you require hot water early in the morning the heater can be switched
“ON” the previous night itself. The thermostat will switch “OFF” the power,
When the water reaches the set temperature.
8. The heater can also be kept “ON” always, if required, Since the heater is
completely insulated, the water will remain hot. The thermostat will switch
“ON” and “OFF” automatically to keep the water at a constant temperature
in the way you can always get hot water at the turn of the tap.
C. Operation in Hard Water areas
1. In hard water areas, a hard salt deposit (scale) forms on surfaces in contact
with water. The scale formed on the heating element reduces the heat
transmission and causes early failure of the element.
2. Scale formation can be reduced by operating the water heater at a
temperature lower than, 50ºC. This can be done by resetting the tempera-
ture to 50ºC or below.
CAUTION
The thermostat is a sensitive device and should not be adjusted
frequently in order to maintain its correct functioning.

3. In hard water areas, the door assembly should be removed and checked
once in a year. The deposits, if any, can be removed by immersion in a
solution of dilute hydro chloric acid for few minutes. Contact the nearest
service centre for this if required.
D. Draining the Water Heater:
The Water Heater can be drained fully by Lifting the drain lever provided in the
MFV. (See gure 4)

Scale formation can be prevented by operating in SMART Mode, Scale (calcium
deposits) forms on top of the heating element when water is heated above
50ºC. When the temperature does not cross 40ºC Scale does not form. This can
prolong the operating life of the heating element substantially as well as avoid
wastage of power.
We recommend trying out the SMART Mode operation and seeing whether it
works for you.

VII. SAFETY DEVICES
Your Venus Water Heater comes with a host of Safety Devices to ensure your safety
at all times.
A. Thermal Cutout
A non-self resetting thermal cutout is provided as a safety device. If the Digital
Temperature Sensor fails to function, this cuts o the power nearly 95 ± 4ºC. The
thermal cutout has to be manually reset before the heater can start operating
again.
B. Multi Function Valve (MFV) :
1. This valve prevents the build up of excessive pressure within the water heater
by releasing water from the valve tip.
2. It also acts as a non- return valve to prevent the return ow of water from the
heater back into the inlet, thereby preventing dry heating.
3. It acts as an expansion valve allowing the hot water expansion during heat-
ing back into the plumbing.
4. Customer can ensure proper working of the MFV by cleaning it of salt depos-
its, by lifting the drain leaver up. Also customer can drain the water inside the
heater by using drain lever for a prolonged period.
