Ariston ABSE VLS PRO INOX PW 50 Assembly And Operation Instructions Manual page 57

To work on the heating elements and anodes, first drain the appliance.
Remove the bolts (Fig. 5, Ref. C) and remove the flanges (Fig. 5, Ref. F). The flanges are coupled to the
heating elements and anodes. During reassembly, make sure to restore the rod carrying sensors and the
heating elements to the original positions (Fig. 7 and 5). Make sure that the f lange plate with the coloured
writing H.E.1 or H.E.2, is mounted in its position marked by the same writing.
We recommend replacing the f lange gasket (Fig. 6, Ref. Z) every time it is disassembled.
CAUTION! Swapping the heating elements will cause the appliance to malfunction. Work on one element
at a time, and only disassemble the second one after the first one has been reinstalled.
Use only original parts from authorized service centres authorized by the manufacturer.
Periodical maintenance
The heating element (Fig. 6, Rif.R) should be descaled every one years to ensure it works properly (the fre-
quency must be increased, if water is very hard). If you prefer not to use special liquids for this operation, simply
crumble away the lime deposit without damaging the heating element. The magnesium anodes (Fig. 6, Rif.N)
must be replaced every two years or the warranty shall be voided (this does not apply to appliances with
stainless steel boilers); however, the anode should be checked every year if the water is corrosive or chloride
rich. To replace them, remove the heating elements and unscrew them from the brackets.
The bypass pipe (Fig. 5, Rif. X) is inspected in the event of fault due to its obstruction. To inspect it remove the
two rings (Fig. 5, Rif. W). After routine or extraordinary maintenance, recommend filling its tank with water and
draining it completely so as to remove any residual impurities. Use only original spare parts supplied by the
manufacturer's authorised service centres
Safety valve
Regularly check that the overpressure device is not jammed or damaged; if it is, remove any scale or replace it.
If the device has a lever or knob, operate it to:
- Drain the appliance, if necessary
- Check its operation from time to time.
Advice for user
- Avoid positioning any objects and/or appliances that could be damaged by water leaks beneath the
water heater.
- Should you not use any water for an extended period of time, you should:
• disconnect the appliance from the electrical supply by switching the external switch to ''OFF";
• turn off the plumbing circuit taps;
- Hot water at above 50°C flowing out of the taps at the point of use could cause serious scalds or even
death from burns. Children, the disabled and the elderly are more exposed to the risk of burns. It is
strictly forbidden for the user to perform any routine or extraordinary maintenance.
To clean the external parts use a damp cloth soaked in soap and water.
ADJUSTING THE TEMPERATURE AND ACTIVATING THE FUNCTIONS (Fig. 8)
The product is set to a temperature of 70°C for the 30, 50 and 80 l models and to 60°C for the 100 l
model. The "ECO" function is active. In case of power shortages, or if the product is switched off using
the ON/OFF button " ", the product memorises the last set temperature.
During the heating phase, slight noise may occur due to the heating of the water. Press the ON/OFF
button " " to switch the appliance on.
Use the " " " " buttons to set the desired temperature to a value between 40°C and 80°C as shown
on the display. During normal operation, the display will show the temperature reached by the water
inside the product. During the heating phase, the status indicator (Fig. 8a/b Ref. 1) is red and turns blue
once the set temperature is reached. If the water temperature drops, for example after a withdrawal, the
heating function will be automatically activated.
