This manual is an integral and impor-tant part of the cylinder and is to be given to the user.

Should the cylinder be sold, its pos-session transferred or the user move out of the premises, this manual is to be left with the cylinder for future user and/or installer reference.

Carefully read the instructions in this manual as they provide important information concerning safe installa-tion, use and maintenance. Keep this manual for future reference.

Cylinder installation is to be imple-mented in accordance with current regulations, manufacturer instructions, and by professionally qualified per-sonnel. “Professionally qualified per-sonnel” means people with specific technical expertise in heating system components for domestic use, certi-fied in accordance with current laws and regulations.

Incorrect installation may cause serious injury to people and animals, and damage to property.

Manufacturer shall not be held liable for any such injury and/or damage.

The cylinder is designed for domestic hot water production and accumula-tion. It is to be connected to a water heating system, domestic hot water distribution system and water main network, compatible with cylinder per-formance and power specifications.

Cylinder use other than specified is forbidden and manufacturer shall not be held liable for injury and/or damage caused by improper or incorrect use.

Cylinder exterior surface is to be clea-ned by means of a cloth dampened in products specifically made for the purpose. Do not use abrasive products or paint thinner. Do not use water.

In order to preserve efficient operation, have the cylinder serviced annually by qualified engineer.

Appliance repair is to be implemented always using manufacturer approved spare parts.

Any accessory to the cylinder has to be manufacturer approved.

Always disconnect electric power and water main supply prior to servicing the cylinder.

Should the cylinder malfunction, turn it off and have it serviced by qualified personnel.Manufacturer recommends an appro-ved and qualified Service Centre to be contacted for servicing.

DHW temperature is adjusted by means of the thermostat knob. Boiler electronics will heat water in cylinder prior to CH system water. When cylinder water tem-perature drops below set level,

DHW pump starts and CH pump stops to allow CH water to cylin-der heat exchanger. (Verify boi-ler technical specs to be com-patible with cylinder operation). Manufacturer recommends kee-

ping cylinder water temperature to 50°C, and raising temperature to 65°C every 15 days for 8 hour in order to prevent “Legionella” bacteria growth.

3 - OPERATION

WARNING: Installation is to be performed in accordance to current regulations and by professionally qualified per-sonnel under penalty of nullity of warranty.

A) Choose a locationIt is advisable to install the cylin-der as close as possible to the boiler, in any case it is important to insulate the connection pipes.

B) Water connection and preli-minary operations- verify volume and pre-set pres-sure of DHW expansion vessel are suitable to the system- should water be particularly hard, install a water softener upstream from cylinder- should water main contain impu-rities, install a suitable filter and verify the pumps have adequate flow rate capacity and pressure head.

When the boiler is placed in a lower position with respect to the water cylinder it is advisable to install a de-aerator on the circu-lator side (3).

Fill up cylinder with domestic water and bleed air in the system by opening a tap. Fill up cylinder heat exchanger with CH water and bleed air in the system. Set DHW temperature on con-trol panel, following the instructions

provided. DHW temperature is best set to 50°C.The cylinder is to be started by qua-lified personnel.

6 - START-UP PROCEDURE

In order to clean external surfaces of cylinder, use a cloth dampened in specific cleaning products. Do not use abrasive, paint thinner, or petrol-based products, etc. Do not use water.On a yearly basis, check magnesium anode fitted on the flange. It can be inspected directly, through the flange or externally by means of a tester.Should water be particularly hard, the cylinder is best to receive a decalcifi-cation treatment at least once a year.

Proceed as follows: empty cylinder by opening the drain tap, then remove the flange to access the inside of the cylin-der. Remove any calcium build up by means of a plastic or wooden spatula and rinse with water.During cleaning procedure, be very careful not to damage internal coating.Upon completion of cleaning proce-dure, install the flange and its sealing gasket (if it is damaged, fit a new one), close the drain tap and fill up the cylin-

der, checking for leaks from flange and drain tap.
