7. Connection to Automatic Pressure Pump
The heater can be connected to an automatic pump system also, provided the line
pressure does not exceed the rated pressure as given in the name plate sticker of the
water heater.
On connecting an automatic pump to the water heater, the Multi Function
Valve(MFV) may drip during the usage of the heater. As the water is heated,
it expands and tries to owback through the inlet-pipe but is prevented by
the presence of the automatic pump. Hence water may drip from MFV. If the
dripping is slow and intermittent, provide a thin tube from the valve tip to a
nearby drain. If it is steady and excessive, call our mechanic. Never try to adjust
the MFV setting, as this will damage the heater.
Important : The MFV should never be removed or blocked by any means to
prevent it from dripping or releasing the excess pressure inside
the heater. The consequences of such an action may well be
disastrous. MFV if tampered, in any manner cancels the war-
ranty of the heater.
8. Connection in high pressure areas
a. The rated pressure of the heater is mentioned on the name plate
sticker.
b. If the water pressure is more than the pressure rating, a pressure
reducer valve should be tted to reduce the pressure accordingly.
c. The output of the pressure reducer valve should be less than or equal
to the rated pressure of the water heater.
9. Connection in low pressure areas :
The water pressure should not be very low. The bottom of the overhead tank
should be atleast 1.0m from the top of the heater. Also, use 25 mm pipe for cold
water line with minimum of bends. An air vent should be provided near the
over head tank to avoid air lock.
WARNING
Do not t a non-return valve or check valve at the inlet.
A non-return valve prevents expansion of hot water inside the container. This
will lead to increase in pressure inside the container till the safety pressure
release valve opens. This will happen in each heating cycle and is not desirable.
So, a non-return valve should not be tted.
Note: Do not use an ordinary stop cock which also acts as a non-return valve.
C. Electrical Connections
1. All internal connections are made in the factory itself.
2. Use a 16Amps 3pin plug and preferably a 30Amps Double pole (D.P).
