1.3 -WATER TREATMENT

• The hardness of the mains water supply conditions the frequency with which the heat exchanger is cleaned.

• In hard water areas where the main water can exceed 15°f total hardness, a scale reducing device is

recommended. The choice of this device has to be made taking into consideration the characteristics of the

water.

• In order to improve the resistance to lime scale it is recommended to adjust the domestic hot water temperature

as near as possible to the one you really require.

• We recommend you to check the state of cleanliness of the domestic hot water heat exchanger at the end of

the first year and subsequently, on the basis of the lime scale found, this period can be extended to two years.

The user has to be instructed on the use and operation of his heating system, in particular:

• Hand over these instructions to the end user, together with any other literature regarding this appliance,

placed inside the envelope contained in the packaging. The user has to keep these documents in a safe

Instructions for the installer

Inspections and maintenances made accor-

ding to the to rule of art and at regular inter-

vals, as well as the exclusive use of original

spare parts, are of primary importance for

an operation exempt from anomalies and a

guarantee of long duration of the product.

The guarantee is valid if the maintenance of

the appliance has correctly been performed.

5

INSPECTIONS AND

SERVICE

The consumer has to be trained on the correct use and on the

operation of his own heating system, particularly it is the duty

of the installer:

- To deliver to the user this instruction manual, as well as the

other documents related to the appliance inserted in the plastic

bag. The user has to guard such documents in order they can

be available for any further consultation.

4

INFORMATIONS TO BE

GIVEN TO THE USER

- To remember that, in the respect of the norms in force, the

control and the maintenance of the appliance must be

performed accordingly to the prescriptions and with the

frequency stated by the manufacturer.

- If the appliance had to be sold or transferred to another owner

make sure that this manual always accompany it, so that it can

be consulted by the new owner or the technician.

3.10- FIRST UTILISATION

Preliminary checks

The first put in operation must be done by professionally

qualified personnel. In the case of damages to people, ani-

mals and goods deriving from the no observance of the

instructions contained in this manual, Unical cannot be

considered responsible.

Inspections and Maintenances not perfor-

med can cause material and personal da-

mages

For this reason we recommend to stipulate an inspection or

maintenance contract.

The inspection serves to determine the real state of an ap-

pliance and to compare it with the optimal state. This happens

through measurement, control, observation.

The maintenance is necessary to eliminate possible devia-

tions of the real state from the optimal state. This takes place,

normally, through the cleaning and the replacement the of

single components submitted to consumption.

ATTENTION!

Before connecting the storage tank to the

heating system proceed with an accurate

cleaning of the pipelines with a convenient

product, in order to eliminate metallic residues of work-

manship and of welding, of oil and of fats that could be

present and that, coming up to the tank, could alter its

operation.

For the washing of the heating system do not to use sol-

vents, because its use could damage the system compo-

nents.

The non observance of the instructions of this manual can

cause damages to people, animals and goods, towards

which the Unical cannot be considered responsible.

WARNING!

Before putting into operation the storage tank it is conve-

nient to ascertain that on the domestic hot water circuit,

the safety valve, the automatic air vent and a drain valve

are fitted.

- In case of particularly calcareous water its treatement is

necessary.

- In case the water supply pressure is higher than 4 bar, a

pressure reducing valve has to be fitted.

- For a convenient optimization of the water outlet tempe-

rature the use of a thermostatic mixing valve is recom-

mended.

- Never exceed the maximum working temperature of sto-

rage tank.

- In case the storage tank is used in combination with a

solar system:

The expansion vessel of the solar system has to with-

stand the high temperatures and the membrane has to be

suitable to the contact with mixture water/glycole.

- To avoid the self natural circulation it is necessary to in-

sert a non return valve.

- Never exceed the maximum temperature of the heating

circuit’s storage tank.

SERVICE

Cleaning of the inside of the tank

Because the cleaning to be made concerns

surfaces which come in contact with the

domestic hot water it is necessary to take all the

precautions in the selection of the apparatuses

and cleaning products.

Before proceeding with the operations of maintenance, perform

the following operations:

- Disconnect the appliance from the electrical supply (if any).

- According to the maintenance intervention to be performed,

close the sanitary circuit or heating circuit gate valves.

To clean the inside surface of the reservoir, proceed as follows:

- Close the gate valves of the storage tank.

- Drain the tank

- Remove the front cleaning flange.

- Clean the inside with a strong water jet. If necessary, to

eliminate scaling deposits use a proper plastic or wooden tool

and rinse.

For the external cleaning of the tank it is recommended the

use of a cloth with water and neutral detergents, avoiding

solvents or abrasive products.

Warning!

During the cleaning works, be carefull not to

damage the enamel of the coil heat exchanger

and of the inside wall of the tank.

Refit the cleaning flange with the relevant

gasket.

Tighten the fixing bolts

Old or damaged gaskets must be replaced.

Every time the inspection flange is removed the

sealing gasket has to be replaced.

Fill the storage tank and check for water leaks

Danger of burn with hot water!

The drain connection of the safety valve must

be always open.

Vice versa, if it is plugged, the storage tank will

explode!.

Control of the protecting magnesium anode

The reservoirs are equipped with a protecting magnesium

anode, whose duration depends on the installation place

(water quality). The anode is screwed on the upper connection

of the tank.

For the maintenance of the anode, placed under the insulation

cover of the tank, it is necessary to remove the plastic cover

and its insulation.

Visual control:

Remove the magnesium anode once a year and check its

condition.

If necessary replace it with a new original one and fill in the

rekord sheet (see the second last page).

To assure for a long time all the functions of your appliance

and not to alter the conditions of the standard product, only

original spare parts from Unical have to be used.

WARNING

Make sure the anode is earthed!
