CLEANING THE INNER TANK AND ELECTRIC HEATING ELEMENT
To keep your water heater running eciently, it's crucial to perform
regular maintenance on the inner tank and electric heating element.
Follow these steps:
• Switching o the power to the water heater.
• Shut o the cold water inlet valve and open a hot water tap to
release any built-up pressure.
• Attach a flexible pipe to the drain outlet and connect it to a
suitable sewage drain. Ensure that the drain pipe you use can
withstand temperatures of at least 34°C. If the drain pipe doesn't
meet this requirement, open the cold water inlet valve and hot
water tap until the water temperature is safe for the drain pipe.
• Open the drain outlet of the water heater and allow all the water
inside the inner tank to empty out. If needed, use water to rinse
the inner tank multiple times to eliminate any deposits.
• After cleaning the tank, close the drain outlet.
• Fill the inner tank with water and turn the power back on.
FILLING THE SYSTEM
Here are the steps to follow for filling and pressurising the system
after it has been properly connected:
• Once the system is correctly connected, proceed to fill and
pressurise the tank.
• To start filling the water system, first, open the non-return valve
on the cold-water inlet. Simultaneously, make sure at least one
hot water tap inside the property is open. As the system fills with
water, you'll hear air escaping from the open hot water tap. This
process, called "bleeding the system," ensures that any trapped
air is removed from the system. When you consistently see water
flowing from the hot water tap, it means the system is fully bled,
and you can then close the tap.
• Always ensure that the tank is completely filled with water before
connecting and activating the electricity supply.
