Multi-function
Safety valve
Note: The Multi-function Safety valve may drip during the usage of the heater. As
the water is heated, it expands and tries to ow back through the inlet pipe but is
prevented by the presence of the non-return valve (an external valve provided before
cold water tap). Hence water may drip from the Multi-function Safety valve. Therefore,
Discharge Outlet is provided to discharge water from the Water Heater. To avoid
dripping, it is recommended to install non-return valve at a distance of at least 40 feet
away from the inlet of the Water Heater.
CAUTION
•The Multi-function Safety valve should never be removed or blocked by any means
to prevent it from dripping or releasing the excess pressure inside the heater.
Failure to do so may result in damage to the Water Heater and injuries to the user.
This will also make the warranty null and void.
•Discharge Outlet is provided to release the discharge from the Water Heater in
case excessive pressure is developed. The contents of the discharge from the
Multi-function Safety valve may be hot and may cause burns to the users and
damage nearby objects, therefore it is recommended to take pre-cautions while
discharging water from the Water Heater.
•It is recommended to operate the Discharge lever in the Multi-function Safety valve
on a regular basis to ensure that there are no blockages and also to remove any
lime deposits that would have been formed inside the Water Heater.
•Ensure that the Water Heater is in power OFF condition when the Discharge Lever
is being operated. Ensure that the water is lled completely in the Water Heater
before switching it ON.
•Ensure that the Multi-function Safety valve is not damaged while tightening.

2. Make necessary plumbing with reference to the Installation Diagram (Refer
“Installation Diagram”).
3. Connect the cold water pipe to the inlet [Blue Sticker].
4. Connect the hot water pipe to the outlet [Red Sticker].
Note: A. O. Smith recommends Nylon/ Stainless Steel (SS) braided hoses (Flexible
Hoses) having a minimum pressure rating of 8 Bar and hoses should be compatible for
hot water applications.
CAUTION
•Make sure a suitable Teon tape is used for all plumbing connections to prevent
leakage.
•Use only Nylon/ Stainless Steel (SS) braided hoses (Flexible Hoses) having a
minimum pressure rating of 8 Bar and hoses should be compatible for hot water
applications.
•Failure to follow this instruction can result in property damage.
Operation
Filling the Water Heater Tank
Figure 13 1. Open a nearby hot water faucet to
permit air to escape.
2. Open the cold water inlet valve fully,
lling the Water Heater and the
piping.
3. Close hot water faucet when water
ows.
4. Check all the connections to see
if there is any leakage. In case of a
leakage, drain the water completely,
repair the leaking joint and then rell
the Water Heater.
CAUTION
•This Water Heater should not be operated with insucient amount of water. Failure
to do so may result in damage to the Water Heater and injuries to the user. This will
also make the warranty null and void.
•Once the Mounting, Multi-function Safety valve, Plumbing and Water lling is
completed, then only the power supply should be switched ON.
•Do not splash water directly or clean with benzene, pesticides, thinner, alcohol, etc.,
but use a soft, dry cloth to clean the Water Heater.
Connecting to Electrical Supply
Figure 14 The power cord and plug are connected
with this Water Heater. Find a separate
socket for power plug and make sure
the socket is in rm contact with the
plug. Ensure that reliable earthing has
been done.
CAUTION
•Connect the Water Heater using independent sockets, do not use any adapters. Use
multimeter to check whether the live line and neutral line are not reverse, to ensure
complete safety.
•Before installing the Water Heater, conrm that the power of Water Heater matches
electric meter capacity and supply wire.
•The Water Heater should be earthed reliably. It is prohibited to connect the earth
wire to neutral wire or faucet water pipe.
