Frequently Asked Questions - Piccolo Ariston Thermo

How to install the Piccolo water heater?

Installation must be carried out by a qualified professional. Fix the mounting plate to the wall with 6 mm plugs. Connect the blue (cold water) and red (hot water) hoses to the corresponding pipes. The unit must be installed less than 1 m above the tap for good flow.

How to adjust the water temperature?

Turn the adjustment knob (F fig. 6) to select a temperature between 40 °C and 80 °C. The recommended position is 60 °C to reduce scale and prevent legionella growth.

What to do if the water does not heat up?

First check the power supply and that the unit is properly filled with water. If the indicator lamp does not light up, the safety thermostat may have tripped: follow the reset procedure (press the Reset button with a screwdriver) or contact a professional.

How to drain the water heater?

Turn off the power supply and close the shut-off valve. Open the hot water tap to empty the unit. For complete draining, unscrew the inlet and outlet hoses. Beware of residual hot water.

When and how to descale the unit?

Descale once a year. Unplug the unit, empty it and remove the heating element. Clean scale with a non-acid product or by gently scraping. Reassemble with a new gasket and a tightening torque of 7-10 Nm.

Why does water drip from the tap during heating?

This is normal: the expansion of water during heating causes a slight flow. Do not fully close the tap to avoid damaging the seals.

What is the lifespan of the Piccolo water heater?

With regular maintenance (annual descaling, gasket replacement), the lifespan is about 8 to 12 years. The heating element can be replaced if necessary.

What are the risks of burns?

Water above 50 °C can cause serious burns, especially in children and elderly people. Set the temperature to a maximum of 60 °C or install a thermostatic mixing valve.

Can I use the unit without water?

No, never power on the unit without it being filled with water. This would irreparably damage the heating element. Always fill before plugging in.

How to activate the anti-freeze function?

Turn the adjustment knob to the * (star) position. The unit will maintain a minimum temperature to prevent freezing. The indicator lamp remains on during heating.

Anti-legionella recommendations (European standard CEN/TR 16355)

Information

Legionella is a small bacterium, of stick-like form, and is found naturally in fresh water.

Legionnaire's disease is a serious pulmonary infection caused by inhalation of the Legionella pneumophilia bacterium and other species of Legionella. The bacterium is frequently to be found in the plumbing of houses, hotels and water used in A/C and air cooling systems. The most effective measure against infection is to prevent the bacterium proliferating in water circuits.

European standard CEN/TR 16355 provides guidelines for preventing the proliferation of Legionella in drinking water systems, without substituting applicable local legislation.

General recommendations

"Conditions favourable to the proliferation of Legionella". The following conditions are favourable to the proliferation of Legionella:

• Water temperature in the range 25 - 50 °C. To reduce the proliferation of Legionella, the water temperature be kept with these limits to prevent them growing or reduce their growth to a minimum. If this is not possible, the drinking water system must be sanitised thermally;
• Stagnant water. To prevent water stagnating for a long time, the drinking water system must be flushed or made to run abundantly at least once a week;
• Nutrients, biofilms and sediment in the circuit, including boilers, etc. Sediment may promote the proliferation of Legionella and should be regularly eliminated from water storage devices, boilers and expansion/holding tanks (for instance, once a year).

As regards storage heater like the present, if:

1) the appliance is switched off for several months at a time or

2) the water temperature is kept constant in the range 25 - 50°C,

the Legionella bacterium may grow inside the tank. If such circumstances, to reduce the proliferation of the bacterium, one must run a thermal sanitisation cycle.

Electromechanical storage heaters are sold with a thermostat set to a temperature higher than 60^ C, which permits a thermal sanitisation cycle to be run to reduce the proliferation of Legionella in the tank.

This cycle is suited to use in domestic hot water systems and complies with the guidelines for the prevention of Legionella given in Table 2 of standard CEN/TR 16355 (see below).

However, the thermal disinfection cycle does not kill all Legionella bacteria in the storage tank. It follows that if the water temperature setting is less than 55^ C, the Legionella bacterium infection may reoccur.

Caution: the water temperature in the tank can cause immediate serious burns. Children, disabled persons and the aged are particularly at risk of burns. Check the water temperature before taking a bath or shower.

See warning no. 10

Local norms could set forth restrictions regarding the installation in a bathroom environment. Therefore keep to the minimum distances foreseen by the applicable norms in force.

The appliance should be installed as close as possible to the point of use to limit heat dispersion along the piping.

! See warning no. 20

Plumbing connection

Before making the plumbing connection, you must arrange for the system to be cleaned thoroughly to eliminate any residue or dirt that could compromise the proper operation of the water heater.

Connect the water heater inlet and outlet to resistant pipes or pipefittings, as well as to the operating pressure, the temperature of the hot water that could at times reach well over 80^ C. We advise against the use of materials that cannot withstand such high temperatures.

We recommend you use dielectric joints for the electrical insulation of the appliance from the water mains.

Connect the inlet pipe (marked with a blue rubber washer) and the outlet pipe (red rubber washer) to the corresponding pipes of the system. Tighten couplings E using a pair of spanners as illustrated in fig. 4

In the event of low mains pressure values, install the appliance at no more than one metre above the tap (fig. 3) and no more than 2 metres form the side of the latter.

Should these distances be greater than the recommended values, you must include an air valve on the hot water pipe. Fill the appliance up and let the water flow out of the tap for a few seconds.

The water flow rate, with the tap turned on fully, should not be more than 5 l/min; for this reason, in accordance with DIN 44531 norm, you should adjust the small valve (fig. 5) to limit the water flow.

In the presence of particularly hard waters, there will be a considerable and rapid formation of limescale inside the appliance, with a consequent loss in efficiency and damage to the electric heating element.

Electrical connection

For greater safety, have qualified personnel carry out a careful inspection of the electrical system, ensuring it complies with the applicable norms in force, because the appliance manufacturer will not be held responsible for any damage caused by the lack of earthing of the system or for faults in the electricity supply.

See warning no. 24 - Check that the system is suitable for the maximum power absorbed by the water heater (please refer to the data plate) and that the cross-section of the electrical connection cables is suitable, and no less than 1.5 mm ^2 .

The power supply cable (type H05 W-F 3x1.5, 8.5 mm in diameter) should be inserted in the corresponding hole (X fig. 6) situated in the vicinity of the control knob and feed it until it reaches the thermostat slots (T fig. 6). The electrical connection should be made directly on the terminals (D fig. 6) of the thermostat (respect the L-N polarity).

The appliance is fitted with a cable and plug. For installations without a plug, use a bipolar switch in conformity with the applicable norms in force (fused with a minimum contact opening of 3 mm).

To access the electrical parts (heating element, thermostat, pilot lamp), remove the cover C by unscrewing screws D (fig. 4).

In the event of an intervention on the thermostat, disconnect the latter from the electricity mains and slide it out of its seat on the heating element. In the event of an intervention on the heating element, unscrew the bolts (A fig. 6) using a 10 mm spanner.

When remounting the components, make sure you put the flange seal, the thermostat, the heating element and all pipes back in their original position.

We recommend you replace the seal each time you dismount the flange.

Once the aforementioned operations are complete, make sure you fill the appliance with water before powering it.

Periodic maintenance

The following operations should be performed annually:

• empty the appliance and dismount the heating element;
• carefully remove all limescale from the heating element parts; if you prefer not to use acids designed especially for this purpose, use non-metallic objects to break off the limescale crust that has formed, taking care not to damage the heating element's armour.
• We recommend you replace the seal each time you dismount the heating element.

To remount the heating element, the tightening torque of the bolts (A fig. 6) should be between 7 and 10 N/m. You must respect the “criss-cross” type of tightening.

Once the aforementioned operations are complete, make sure you fill the appliance with water before powering it.

Resetting the bipolar safety

In the event of an abnormal overheating of the water, a thermal safety switch in compliance with CEI-EN norms cuts off the electrical circuit on both the power supply phases of the heating element.

To reset the operation of the appliance, proceed as follows:

- leave it to cool;

- set the knob (F fig. 6) to the maximum temperature position;

- remove the cover C by unscrewing screws D (fig. 4);

- disconnect the thermostat (T fig. 6) from the electricity mains;

- using a cross-head screwdriver, press on point A fig. 9 until you hear it click.

Remount everything in the reverse order, paying particular attention to repositioning the components correctly.

Once the aforementioned operations are complete, make sure you fill the appliance with water before powering it.

USER INSTRUCTIONS

Operation

To turn the water heater on, insert the plug into the wall socket or switch on the bipolar switch.

The pilot lamp (A fig. 4) only stays on during the heating cycle; during this time, the expanding water could cause some water to trickle from the tap: this is completely normal and does not mean the tap is faulty. Do not screw the taps too tightly to prevent damaging their seals.

The thermostat will automatically disable the heating element as soon as the selected water temperature is reached. During the final stage of heating, it is normal for a few cycles of thermostat starting and stopping to take place.

During normal operation, the electric heating element may make a little noise inside the appliance, which is due to the heat exchange; the plumbing connections may also become hot to the touch.

Adjusting the operating temperature

The temperature of the water can be selected on the knob (F fig. 6) and can be adjusted from 40 to 80°C approximately. We recommend you set the temperature of the water heater to 60°C to:

• reduce the formation of limescale;
• reduce heat dispersion;
• avoid the risk of bacteria proliferation.
