Electric Showerheads

And the other way round? Can I do it?In the case of showers from the 127V models without electronic control and a pressurizer, if the heating element is replaced by another one of the same model – but in the 220V tension – the shower will work normally in a 220V installation, as its internal mechanisms are sized to receive electrical currents and dissipate heat properly.

However, you should take care with the marks shown in the shower, which will indicate that is a 127V model. This may cause confusion in future maintenance or for new house owners. Therefore, you should by a shower in the proper tension.

In the case of a 220V shower the resistor should never be replaced for a 127V version and it should never be installed in a 127V network, since it is not prepared for such condition and safety may be compromised.

The neutral wire should never be used as grounding. Should the power network be overcharged – as in the case of lightning – the neutral wire may be charged and burn the electrical devices which are connected to it.

The directions for changing the heating element are contained in the guide that accompanies the product at the time of purchase.

In order to avoid of electric shocks the ground wire (green or green/yellow wire) should be connected to a grounding system, according to Brazilian rule NBR-5410.

The electric installation and the grounding system for this device should be performed by qualified people. The grounding system ensures your safety during the use of household appliances.

What side should I turn it to?Once the shower has been installed, you should look at it from underneath and turn the spreader anticlockwise.

The power is stated on the packages and is a unit that measures the maximum heating capacity of an electric shower.

The highest the power, the highest the temperature the shower water can achieve. It is expressed in Watts and W is its symbol. The usual maximum powers of Lorenzetti Showers are 3200 W, 4500 W, 5500 W, 6800 W and 7500 W.

When you change the position of the shower temperature switch, it starts to operate in powers which are lower than its maximum power, thus making water less hot and saving electric power.

The intermediary operation powers for Lorenzetti’s Electric Showers can be found in the respective instruction guide.

3-temperature showers are those in which the temperature change switch provides 3 different power options: maximum, medium and zero. As a requirement, a 3-temperature shower can have a maximum power of 5500W, whether its tension is 127V or 220V.

Lorenzetti’s Multi-Temperature Showers are those in which the temperature change switch provides 4 different power options: maximum, medium 1, medium 2 and zero. In these showers, the 220V tension is usually 6800W or 7500W, which enables a great water heating.

These showers also allow the user to save a large amount of power, as they have two intermediary power options. The 127V multi-temperature showers, due to a requirement, can have a maximum power of 5500W.

Lorenzetti’s Electronic Showers feature a turning button for controlling the electric power – rather than a temperature change switch – which allows the water temperature to be gradually set.

Theses models provide users with maximum comfort and power saving, since it’s possible to achieve the precise temperature that suits them best in any weather. The 220V Lorenzetti Showers have a maximum power of 7500W. Due to a requirement, 127V electronic showers can have a maximum power of 5500W.

Electric tension is the difference of electrical power between two points. Voltage is a synonym colloquially used in Brazil. Volt is the measurement unit for the electric tension and its symbol is V. 127V and 220V are standards for the secondary tensions received in Brazilian houses.

In some regions, houses are served by 127V and 220V tensions, while in other regions they receive 127V only or 220V only. For historical reasons, the 127V tension is also called 110V, which was a secondary tension used by energy providers in the past.

Before buying an electric shower, check the electric tension available at the power source where it will be installed. As opposed to what it may seem, the electric power consumption depends on the shower power rather than on its tension.

Their purpose is to ensure safety. Connectors provide a good electric contact between the device wiring and the house installation.

A better electric connection means that there is a good contact area between the two sets of wiring and that the electrical current finds less resistance to circulate.

This makes the connection safer, since it avoids the set heating while increasing the useful life of the device and the installation. The right way to use them may be viewed in the device installation guide.

The Turbo (or Pressurized) model is equipped with a pressurizer, which increases water pressure and provides a more pleasant shower. The Turbo model is suitable for those who live in places where the water pressure is low.

The Master model doesn’t come with a built-in pressurizer and suitable for those who live in places where the water pressure is good.

It should be installed whenever the pressure is higher than that determined in the product installation guide. The use pressure varies according to the model.

In the case of Maxi Ducha, the reducer should be installed from 80 kPa, which corresponds to 8-m water column.

The circuit breaker and the wiring are subject to two factors, namely the product tension and power. See the table below for the technical specifications of the different models of showers and power showers:

For distances above 30m, use larger section conductors.

As it is fed by an alternating current, an electric shower doesn’t have positive or negative wires.

In the alternating current, as the word itself indicates and as opposed to the direct current, the current extension and direction alternate according to its frequency.

As a result, there is no order for the electric connection of the shower wires to those of the power network.

General use plugs and sockets are not prepared to resist to the electrical current that circulates in Lorenzetti’s heating household appliances, as such appliances have a high electrical power. Their use compromises the installation safety.
