Mounting And Installation of Bajaj Instant Water
Heater (Fig. 2)
1.
Mount the Instant Water Heater (IWH) at a suitable place on the
wall. Ensure that it's in a perfectly vertical position.
2.
It is advisable to connect the unit to a D.P. switch fuse unit of 16
Ampere rating.
3.
Connect the inlet of the unit to the supply line from the overhead
tank or municipal water supply as the case may be.
4.
In case of pressure type installation (Multipoint usage) get a
licensed plumber/electrician to connect the outlet of the heater to
the various points of usage.
5.
The cold and hot water pipes should not be connected directly to
the inlet and outlet of the heater. They should instead be
connected by flexible tubes of appropriate material. Never use
plastic tubes especially at the outlet as it cannot withstand the
heat. In case of direct pipe connections, tightening of couplings
using wrench can damage the heater unit. Use a control valve at
the inlet. Ensure that it is always kept open. (In Pressure Type
Installations)
6.
The overall & mounting dimensions are shown in Fig. 2.
How to Operate? - Pressure Type installation. (Fig.
3)
1.
With this installation you can take hot water out at more than one point of usage.
2.
Allow the cold water to flow from the outlet.
3.
Keep the Gate valve at the inlet ALWAYS
OPEN.
4.
Switch ON the power supply to the unit.
5.
The hot water flow at the usage point can be
controlled by the Gate valve provided at the
usage point.
6.
Ensure that Pressure at the inlet is not more
than 50 PSI. In case it is more, install a
Pressure Reducing Valve at the inlet.
7.
After use, first switch OFF the power supply.
8.
Allow the hot water to flow out. This
enhances life of the element by preventing
scaling.
9.
Close the gate valve at the usage point.
