SAFETY VALVE

This water heater has a temperature and pressure safety valve. This valve is designed

to automatically relieve and discharge water incase the pressure or temperature

overshoots the preset limits

Safety Valve helps to relieve and discharge water in case pressure or temperature exceeds

preset limit

The colored LED module displays actual temperature and set temperature. It also

displays off-peak, timing, clock and power modes to enable you set these options.

Electronic Controls & Display helps set temperature and power options

Blue Diamond Glass Lining offers the best protection against tank corrosion

The new Blue Diamond technology with enhanced levels of zircon increases the life

of the water heater. The lining is proven to be stronger and more water-resistant than

any other in the Industry.

Dual Glass Lined Heating Elements increases the life of the heating element and heats

water faster

Dual Glass Lined Heating Elements provide extended life to the water heater by

preventing Scale Formation on the element surface. They help in quick water heating.

In the event of one glass lined element failing, the other element ensures that water

gets heated. It is recommended in all areas that have hard water.

DUAL GLASS LINED

HEATING ELEMENTS

Key Features

The tank has an anode rod system with a stainless-core that is designed to protect the

tank from corrosive elements. The system uses a special cathodic action to fight the

corrosive elements which in turn prolongs the life of the water heater.

Safety Features

The water heater employs a high temperature limit protection switch which is reset by manual operation.

The switch rapidly cuts off the phase and neutral line simultaneously to guarantee safety in case the water

heater happens to be faulty and the water temperature exceeds the highest temperature preset in the

thermostat. If this happens, please call the Customer Care Center.

We strongly suggest that you read this manual thoroughly before installation and use of this water heater.

Be sure to keep the manual for future reference.

• A. O. Smith Company will not be liable for any damages resulting from incorrect installation of this

water heater. Only professionals recognized by A. O. Smith should be allowed to install this water

heater for you.

• Be sure to shut off the power before carrying out any repair and maintenance on this water heater.

Non-professionals should not be allowed to adjust or repair this water heater.

• Hot water may cause serious scalding injury. Hot water must be mixed with cold water before usage.

• The water heater may produce steam or extremely hot water if operated without enough water inside

the tank. Make sure the water heater is full of water. Any part supposed to be immersed in water

needs to be examined or repaired by qualified professionals before further use.

• In case of a damage to the power cord of the water heater, only manufacturer’s customer service

personnel or similar professionals are allowed to replace it. All key parts of this water heater are

electrically insulated and have heat-insulated layers, so users may be assured while using it.

• The water heater is equipped with a pressure-relief safety valve. It is prohibited to change the

installation position of the pressure-relief safety valve without permission, or block its outlet. The

pressure-relief safety valve must be equipped with a discharge pipe, which is facing downward

without any knot and connected directly to the floor drainage.

Attention: If the content in the manual is not strictly abided by, fire may be caused which may lead to

property loss, personal injuries or death.

Warning: A power socket cannot be used unless it is securely grounded, and it is forbidden to use a

water heater without being securely grounded. Floor drain openings with good drainage

conditions should be arranged near the water heater.

General Safety Information

Installation Instructions

Place the heater near an electric power socket, floor drain and the terminal for hot water utilization. There

must be a floor drainage, since there may be water flowing out of the pressure relief port of the press

relief safety valve, when the water heater is being used. Be sure the inlet and outlet of the heater are on

the bottom and are facing downward. It is forbidden to install the water heater vertically.

Warning: Be sure to install the water heater with the provided mounting hangers. The heater can be hung

up only after it is certain that the mounting hangers are solidly mounted. Serious damage and

harm may result if the heater falls off from the wall.

Installation Procedure and Cautions

• Make sure that the wall can withstand fourfold weight of a fully filled water heater.

• To locate the fixing bolts, make sure that there is a clearance of no less than 300 mm between the

right side of the heater and the wall in order to open up the plastic service cover for maintenance or

reset the high limit when necessary. In case, the water heater is embedded in the ceiling, the right side

ceiling of the heater should be removable so as to remove the plastic service cover for maintenance

when necessary.

• Use a drill bit with a diameter of 10 mm to drill 2 holes at least 90 mm deep in the wall. The 2 holes

should be in line horizontally. The distance between the 2 holes is as shown in the below diagram.

• Use the inner hex wrench and expansion bolts to mount and fix the hangers on the wall. Refer to the

first diagram on next page.

Particular Cautions

• The nylon expansion tube must be put through the hole of the hanger first, before being inserted into

the drilled hole.

• Only special hex wrench should be used to drive the bolt into the nylon expansion tube. Once, the bolt

head has pressed against the hanger plate and made the hanger unmovable, stop further tightening

to prevent damaging the nylon tube.

Mounting

Hanger

Screw

• Hang the water heater on the wall by placing the 2 holes of the mounting bracket onto the hanger

hooks. Move the water heater downward to ensure that the square holes are pressing on the root of

the hanger hooks and confirm water heater is fixed steadily.

Caution: The provided mounting hangers can only be used on solid cement wall. Inappropriate

installation may result in heater falling down. See the diagram below for details.

Correct Wrong

Black

Connect the pressure-relief safety valve in the water inlet (on the side of the blue plug cap) in the

direction of the arrow pointing in the direction of water flow (i.e. pointing to the water heater). Connect

hot water pipe to the outlet (on the side of the red plug cap). See above content on safety valve for

the installation of the safety valve. In case, the water pressure is close to over the safety valve

rating (0.8Mpa), please install a pressure-reducing valve in the inlet piping with sufficient distance

from the heater. Refer to the below diagram for water connection details.

Attention: Make sure a suitable tape thread sealant is used for all connections to prevent leakage.

Meanwhile, the safety valve must not be excessively tightened so as to prevent damage.

Plumbing

Black

1. Make necessary plumbing with reference to the below diagram.

2. It is recommended that suitable nylon braided hoses should be used. These hoses should have a

minimum pressure rating of 8 Bar and should be compatible for hot water applications.

3. Connect the cold water pipe to the inlet [blue].

4. Connect the hot water pipe to the outlet [red].

Attention: Make sure a suitable sealing tape is used for all connections to prevent leakage. Meanwhile,

the safety valve must not be screwed too tight to prevent damage.
