A. Do not
B Do Not SWITCH ON water Heater without water filled in tank.
1. In case inlet water pressure is more than 5.5MPa or water pressure head 80 meter, install the dead weight
valve before inlet as shown in Picture 2 (not provided with this unit).
2. Minimum height between the water heater and water supply tank should be at least 4 meter.
3. For connecting the inlet & outlet between water heater and bathroom fittings, use metal flexible pipes.
4. Cold water inlet is marked blue and hot water outlet is marked with red.
5. First, fix the multifunction valve (MFV) to inlet of water heater.
6. Connect cold water inlet to other end of MFV with metal flexible pipe.
7. Open inlet water tap and allow the water to fill in the water heater. Make sure that the water starts
flowing from outlet of water heater.
8. Connect the outlet with metal flexible pipe to hot water outlet point of bath fitting. Open the tap & valve and
check the water flow through the hot water tap
9. Connect MFV with PVC pipe for drain see Picture 3.
connect the inlet directly to water lifting pump.

1. This unit is provided with all internal connections/wiring made in the factory itself.
2. The water heater is provided with a supply cord, with 3 pin plug top of 15 Amp.
3. Make sure that the electrical contact of 3-pins plug and switch is secure with proper earthing
4. To energize water heater plug in the 3-pin in socket for electric supply.
Internal Wiring Diagram -

500mm from sides & minimum 1.8 m from ground).
C. Ensure following tools and accessories are made available before installation of this unit.
(not provided by company)
1. Drilling machine with concrete drill bit, set spanner and tool kit.
2. Two numbers of metal flexible pipes.
3. PVC pipe for drain
Preparation of Wall Structure
For installation of this unit, you need to prepare the wall suitably.
A. In case of hollow brick walls.
1. Dig up sufficient space to accommodate the wall mounting bracket (bracket supplied with water heater)
of minimum depth 100mm.
2. Fill up the complete dig up space with cement concrete.
3. Ensure cement concrete is properly cured/set.
4. Then, the wall bracket can be fixed with the help of bolts provided along with the unit.
B. In case of solid walls
Follow process as below :
1. Drill hole in wall as shown Picture 1.
2. Insert the nut/bolt assembly in drilled hole,
take out the bolt (as shown) Picture 1.
3. Fix the wall plate with the bolt and washer by testing testing
till the wall plate is firmly fixed, in order to carry the
weight of water heater safely (with water).
Always use services of qualified plumber/electrician to install this unit.
C. Multi Function Valve (MFV)
1. This valve prevents the built-up of excessive pressure within the water heater by releasing water from the drain.
2. It also acts as a non-return valve to avoid the return of water from the water heater back to supply,
thereby prevent the dry heating.
3. It acts as an expansion valve to allow the hot water expansion during heating which flows back through drain.
4. Customer can ensure proper working of the MFV by cleaning of salt deposits, by lifting the drain lever up.
Customer can drain out the water from tank in case of prolonged non-use of water heater.
A. Hollow brick walls. B. Solid walls.
