Safety Precautions

During Installation

Do not install the Water Heater where there is direct sunlight or rain. It is has to be installed indoor only

Do not install the Water Heater where water splashes on the Water Heater.

Installation

Before installing, ensure the tools Adjustable wrench, Teflon tape, Measuring tape, Hammer, Bubble level indicator and Impact drill tool are available.

Mounting the Water Heater

• It is recommended as per IS302-1 to have 6 inches clearance from wall.

• Select a place to mount Water Heater vertically with water connection at the bottom.

• • Water Heater must be located within 2.5 ft. (approx.) from a 230 V electrical outlet with proper grounding.

• Make sure that the wall can withstand at least twice the weight of the Water Heater when completely filled with water.

Use a drill bit with diameter of 12 mm to drill 2 holes at least 90 mm deep in the wall (Step 3). The two holes should be aligned horizontally. The horizontal distance between 2 holes is 75 mm.

• Insert the Expansion Anchor into the hole (Step 1).
• Insert the Hanging screw over the Expansion Anchor and tighten the Hanging screw by rotating it till it gets fixed steadily (Step 2).

Mount the Water Heater on the Hanging screw through Wall mount bracket. Tug downwards on the Water Heater to ensure that the Water Heater is fixed steadily

Connecting Multi-function Safety valve

Wrap the threaded part of the cold water inlet pipe with Teflon tape in clockwise direction.

Connect the Multi-function Safety valve to cold water inlet pipe and rotate it in clockwise direction till it gets fixed.

Note: 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.

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 filled completely in the Water Heater before switching it ON.

• Ensure that the Multi-function Safety valve is not damaged while tightening.

Connecting to Water Supply

*Flexible Hoses to be procured by the customer, not part of standard product.

1. Wrap the Teflon tape around the inlet and outlet connections of the Water Heater to prevent leakage.
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 Teflon 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

1. Open a nearby hot water faucet to permit air to escape.
2. Open the cold water inlet valve fully, filling the Water Heater and the piping.
3. Close hot water faucet when water flows.
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 refill the Water Heater.

CAUTION

• This Water Heater should not be operated with insufficient 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 filling 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

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 firm 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, confirm 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 Provider in order to avoid a hazard.

Temperature Control Knob

Switch on the Water Heater’s power supply. The Heating indicator LED glows.

Temperature Setting

Turn the Temperature control knob clockwise for the device to commence heating and change the set temperature [The set temperature increases if the Temperature control knob is turned clockwise]. Temperature can be adjusted from 25°C to maximum 75°C. Modes

There are two types of modes depending on the actual water temperature inside the inner tank of the Water Heater:

When the actual temperature of the water is less than the set temperature, it enters into Heating mode. The Heating indicator LED glows as shown in “Figure 16”.

| After the Water Heater reaches set temperature, it will enter into the Standby mode due to the thermostat cut-off, the Heating indicator LED switch off as shown in “Figure 17”.

When the temperature of the water drops by 5°C from the set temperature due to usage of water, the Water Heater again enters into the Heating mode.

Draining the Water Heater Tank

Whenever the Water Heater is not used for an extended period or if the product is below freezing temperature, you will need to unplug the unit and drain it.

|

1. Switch OFF the electric supply to the Water Heater.
2. Open the hot water faucet until the water runs cool.
3. Close cold water supply.
4. Drain the water by lifting the Discharge Lever of the Multi-function Safety valve upwards. (Refer “Figure 18”)
