*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 Teflon 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
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 flow 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.
