This manual is an integral and essential part of the product. It should be kept

with the appliance so that it can be consulted by the user and/or authorised

personnel.

Please read carefully the instructions and notices about the appliance

contained in this manual, as they provide important information regarding the

safe installation, use and maintenance of the cylinder.

Failure to do so may invalidate the guarantee.

When installing and servicing the cylinder, Ariston Thermo UK Ltd

recommend the use of protective clothing i.e. gloves.

The Ariston range of unvented cylinders come with varying guarantees

depending on the model of cylinder. The guarantee periods offered with

each model of cylinder are as follows:

ST Range

Classico HE Range

Aquabravo Range

Note: The guarantee is subject to the cylinder being installed and serviced

annually by a competent person as per the maintenance instructions in

Section 5.6 of this manual. For units with the ProTech anti-corrosion device

it must be ensured that this is connected and operating correctly (green LED

only).

The immersion heater(s) are controlled through a thermostat which senses

the water temperature. The operating temperature can be pre-set by

adjusting the spindle in the head of the thermostat. In addition to the

thermostat there is a thermal cut-out incorporated if the thermostat fails and

the water temperature rises too high. Once the cut-out operates it can only

be re-set manually after the fault has been rectified.

Indirect models have dual thermal controls. In addition to the above there is a

separate cylinder thermostat and thermal cut-out for controlling each indirect

circuit. Again the thermal cut-out operates if the cylinder thermostat fails, by

disconnecting the live feed (call for hot water) from the programmer.

ITI/ITD/ITSI models have a stainless steel tank and therefore need no

protection against corrosion.

STD/STI models have an enamelled steel tank and therefore are supplied

with magnesium anodes to prevent corrosion of the cylinder tank. It is

imperative that the top anode is checked during the annual service and if

found to be corroded both anodes should be replaced. Failure to do so will

invalidate the warranty of the tank.

The Wall-hung (ST) units utilise the ProTech anti-corrosion system

(electronic anode). This prevents an electrolytic reaction between the tank

and dissimilar metals. The ProTech system shows if it is operating correctly

(green LED) or incorrectly (red LED). In the event that the red LED lights

(even with the green light still showing), it is imperative that a service agent

is contacted immediately as continued use with the ProTech system in this

state could invalidate the warranty on the tank.

Note: Do not use a water softner on products with the ProTech anti-corrosion

system.
