Removing the heating element

1.Turn off power supply and drain the heater (see previous section).

2.Remove the front cover plate, disconnect terminals X, Y and T (fig. 3/2).

3.Unscrew the 4 heating element retaining nuts F (fig. 3/2).

4.Remove the element. G (fig. 5/1).

Descaling the heating element

Scale deposits can affect the heating capability of the element.

Heavy scale can even cause the element to burn out. The element can be descaled either chemically or manually:

A)Soak the element in white vinegar or other descaling solution. Once descaled, rinse well with fresh water, to which you should add some baking soda, OR

B)Once the element has dried up, use a soft brush (non metallic to prevent damaging the stainless steel sheath) on element. Brush the dried mineral off. Reinstall the element with gasket and make the wire connections.

C)Replace anode rod (N Fig. 5/2) if it is noticeably deteriorated or considerably shorter then seen in figure 5/2.

WARNING: make sure the tank has been refilled with water before restoring power.

REPLACEMENT OF PARTS

Changing the anode rod

The anode rod (N fig. 5/2) helps protect the tank against corrosion. Depending on the water condition, the magnesium anode rod may need to be changed every year or so. Galvanic and electrolytic corrosion can destroy a tank if the anode rod is “spent”. Rusty water is usually an indication of a “spent” anode rod. If rusty water is present, examine anode rod immediately. Rapid degradation of the anode rod (less than 1 year) may indicate the presence of galvanic corrosion due to “stray” direct current. In this case, it may be necessary to add a “grounding strap” from the Ariston tank to the copper plumbing.

1.Turn off the power supply and drain the heater (see Draining the Heater).

2.Remove heating element (see previous section).

3.Remove and replace the anode rod N Fig. 5/2.

4.Refill tank with water before restoring power.

The GL 4 Ti model, with a capacity of 4 liters, is perfect for small households or for use in specific applications like kitchen sinks or handwashing stations. Despite its compact size, it features a 1500W heating element, providing quick heating for immediate hot water needs. Its lightweight design also allows for easy installation in tight spaces.

Moving on to the GL 2.5 Ti, this variant offers a slightly larger capacity of 2.5 liters, making it ideal for bathrooms or other small spaces where hot water demand is moderate. The unit’s compact design complements its energy-saving features, including a thermostat for precise temperature control. Users can easily adjust the water temperature to their preference, ensuring comfort and safety.

The GL 8 Ti model is the largest in the series, boasting an 8-liter capacity, suited for larger households or situations where multiple outlets require hot water simultaneously. With a robust 2000W heating element, it heats water rapidly, reducing wait times. This model also embraces eco-friendly technology, offering an Energy Saving mode that optimizes energy usage according to demand, making it an environmentally conscious choice.

All three models are equipped with a user-friendly control panel, providing straightforward operation and monitoring. Safety features are paramount in the design, with multiple cut-off systems to prevent overheating and protect users. Additionally, the units come with a double safety valve, emphasizing the commitment to safe water heating practices.

In summary, the Ariston GL series, including the GL 4 Ti, GL 8 Ti, and GL 2.5 Ti, reflects a perfect balance of efficiency, safety, and durability. The innovative technologies embedded in these models cater to a variety of hot water needs, making them compatible and reliable for modern living.
