D.
There should be a minimum space of 50 cm between the top of the heater and the roof. This is to make sure
that the heater can be removed and taken out when necessary.
E.
The heater should be saved from being damaged by splashing of water. Therefore, keep a minimum space of
about 1.8 m. between the floor and bottom of the heater.
F.
During installation and plumbing (preferably by flexible metal pipes) remove the coupler cover by pulling it
out towards the front of the water heater. Connect the plumbing by bending the flexible pipes or elbow as
shown in fig. 2. sideview. Slide the coupler cover to complete the plumbing.
WATER SUPPLY.
A.
You can connect the heater directly to municipal water supply or vent pipe the water tank on top of your
house.
B.
If the height is more, use a Pressure reducing valve at the inlet.
C.
The water pressure should also not be too low. The minimum distance between the heater and the water
supply tank should be at least 2 metres.
D.
YOU SHOULD INSTALL THE VENT PIPE FROM THE TOP OF THE HEATER ABOVE THE LEVEL OF THE WATER
SUPPLY TANK. THERE, IT SHOULD BE LEFT OPEN TO THE ATMOSPHERE. THIS IS THE SAFEST METHOD OF
INSTALLATION.
WATER CONNECTIONS:
Do not connect the cold and hot water pipe lines directly to the heater.
Instead, connect them using flexible tubes of appropriate material. Never
use plastic tube especially at the outlet because it cannot withstand the heat.
In case of direct pipe connections, tightening of couplings using a wrench
can damage the heater unit. USE A CONTROL VALVE AT THE INLET. MAKE
SURE THAT IT IS ALWAYS KEPT OPEN.
WIRING
All the electrical connections inside the Heater are done at the factory. The
water heater is provided with a supply cord and 3 pin plug, which should be
connected to main power supply. Connect the red wire to phase, black to
neutral and green to earthing. Make sure that the connections in the plug
and socket are right, and proper earthing is provided to the unit.

THE OPERATION PROCESS
Operation Instructions:
Normally, Water heaters are connected to the water tank situated on top of the house. Since the heater unit is
designed to operate at a given working pressure, the exact installations are different. To help you install the unit
correctly, various alternatives are shown in Fig. 4 and 5.
1.
Do not switch ON before filling the heater unit with water.
2.
Leave the hot water outlet open and open the inlet valve to allow the heater unit to be filled with water. After
it is full the water will start flowing out from the outlet.
3.
Now close the outlet cover. ALWAYS KEEP THE INLET VALVE OPEN.
4.
Switch ON the power supply. Green neon lamp will glow ON to indicate that water is getting heated.
