*Flexible Hoses to be procured by the customer, not part of standard product.
**Multi-function Safety valve comes included with the Water Heater.
1. Remove MFSV from the inlet pipe by rotating it in anti-clockwise direction.
2. Wrap the Teon tape around the inlet and outlet connections of the Water Heater to prevent
leakage.
3. Connect MFSV to the inlet pipe by hand tightening it in clockwise direction.
4. Make necessary plumbing with reference to the Installation Diagram. (Refer“Installation
Diagram”)
5. Connect the cold water pipe to the inlet [Blue Cap].
6. Connect the hot water pipe to the outlet [Red Cap].
Note:
•Make sure to connect Multi-function Safety valve to the Water Heater before connecting inlet
to the cold water tap.
•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.
•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.
7

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(through the
Multi-function Safety valve) 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.
•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 11 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 12 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.
•If the power supply cord is damaged, it must be replaced by the manufacturer or Authorised
Service Technician in order to avoid a hazard.
Installation of Wireless Router
1. Install the Wireless router using user manual.
2. HeatBot®-Wi-Fi supports only Wi-Fi 2.4 Ghz products.
