   • c. Pressure release valve
   • d. Drain valve
8. Compact size.
9. Drip proof construction.
10. Special flush mounting .•
11. Smart Mix:

During the use, every withdrawal of hot water from the water heater is then balanced by cold water coming in. The “Smart Mix” technology provides better management of the cold water coming inside the water heater. The special Smart Mix deflector allows the water to mix more slowly, keeping the internal water tempera­ture high and avoiding re heating of water unnecessarily thereby saving precious electricity. The Smart Mix system, with its new deflectors of water coming in, allows the user to draw upto 10% more hot water than a traditional water heater of the same capacity.

SAFETY DEVICES

A. Multi functional Safety Valve :

In-built multifunction safety valve (Pressure relief valve) is set to operate between 7.5 bar (109 p.s.i.) to 8.5 bar (123 p.s.i.). Drain lever (L) is provided to drain the water heater only in case of servicing as shown in Fig.2.To avoid deposition of lime in the safety valve, please move the lever(L) up and down few times once in a 6 month. lncase of safety-valve dripping during normal use, connect a discharge pipe (P) as shown in Fig.2.This will happen only if the pressure inside the tank reaches beyond rated pressure limits.

B. Thermostat :

Hi-tech adjustable thermostat with automatic ON OFF display and variable settings. The temperature of the thermostat can be adjusted by varying the knob position. The thermostat can be withdrawn without draining the water from water heater.

C. Thermal Cutout:

Hi-tech thermal cutout non-self resetting type set to disconnect electrical connection in case of any fault occurs and/or the water temperature exceeds the present limit (this ensures extra safety). Please contact Only authorized service personnel in such an event.

OPERATIONAL INSTRUCTIONS

• A= Arrow Mark (Reference Point), B= Red Lamp, C= Display Slicker,
• D=4) Temp control knob (clockwise incremental)
  • E= Blue Lamp

1. 1. Switch on the water heater’s main supply, red and blue indicator lamp comes on.
   2. The arrow mark knob should be position as per bathing requirement using the point mention on the display sticker.
   3. The red indicator lamp switches off indicates water inside the water heater reached to the set temperature .
   4. The Blue indicator lamp, which is ON during the normal operation, goes OFF when the thermal cut-out is activated. Contact qualified service personnel in this event.

SMART BATH LOGI

The intelligent Smart Bath Logic indicators around the temperature regulator knob allows you to choose the hot water requirement to suit to your bathing requirements and thereby choose the amount of power the water heater consumes. The Smart Bath Logic indicators allow you to be in total control of the energy consumed, by adjusting the knob to the required position The following are the indicative saving in each of the desired knob positions as compared to the maximum thermostat setting.

PREPARATION FOR INSTALLATION

1. For the installation of this water heater you need to prepare the wall suitably and more so if the wall is constructed out of hollow bricks.
2. For solid bricks the usual method of installa­tion of drilling holes in the wall and securing bolts in the right position with the help of cement concrete can be adopted, use MS x 75 mm bolts.
3. However for hollow bricks the following procedure should be adopted: Dig up sufficient space to accommodate the wall mounting bracket supplied with this water heater, upto a minimum depth of 80mm and till up the complete space with cement concrete. After the cement concrete is properly set the wall bracket can then be secured to the wall with the help of bolts. It is very important to put the wall bracket only after the cement concrete has set in.

FOR VERTICAL INSTALLATION

INSTALLATION

Mounting and plumbing

ELECTRIC WATER HEATER INSTALLATION GUIDELINE FOR PLUMBERS

• Read Instruction Manual carefully and follow installation instructions.
• Check product type : Whether Vertical or horizontal, if Horizontal whether wall Mounting (WM) or Floor Mounting (FM) and install accordingly.
• Safety valves are pre-set for certain working pressure . Under any circum­stances do not tamper/ over-tighten the safety valve.
• Continues water dripping from Safety valve is an indication of excessive pressure at inlet of water heater compared to the rated pressure. In that case install pressure reducing valve at the inlet
• Check for leakages after installation, plumbing & before switching ON the power supply.
• Ensure flow of water from outlet before connecting electric power supply to the appliance.
• Do not use excessive force while tightening inlet and outlet Couplings. This may cause serious damage to the Water Heater. Use Cross spanner for tightening.
• Check supply voltage at the place of installation 230V.
• Ensure proper earthing of electrical connection.
• No extension cords to be used.
• Use only ISi marked electrical accessories of proper rating e.g. 3 Pin Plug, Connection Boxes, Wires etc.
• In Storage water Heaters , check whether both blue and red lamps are glowing when the water heater is switched on.
• Ensure all Couplings/ Joints are leak-proof.
• Check the Water Heater operation for one complete cycle i.g. one cycle of Thermostat operation, i.e Cut-off and cut-in
