1.2 -CORRECT USE OF THE APPLIANCE
The appliance has been designed utilizing today’s technical level and in compliance with the current safety
regulations. However, following an improper use, dangers could arise for the safety and life of the user or
of other people, or damage could be caused to the appliance or other objects.The appliance is designed to
be used in hot water central heating systems, with a dedicated loading pump for the D.H.W. storage
cylinder. Any other use of this appliance will be considered improper. UNICAL declines any responsibility
for any damages or injuries caused by an improper use; in this case the risk is completely at the user’s
responsibility. In order to use the appliance according to the scopes it was designed for it is essential to

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:
• Handovertheseinstructionstotheenduser,togetherwithanyotherliteratureregardingthisappliance,
placedinsidetheenvelopecontainedinthe packaging. The user has to keep these documents in a safe
place in order to always have them at hand for future reference.

appliance respect the following safety indica-
tions:
- Put the appliance in places in which it is pos-
sible to prevent the access from children, as
potential source of danger for their safety.
3.5 - PRELIMINARY CHECKS
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 workmanship 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.
Thenon observance of the instructions of this manual can
cause damages to people, animals and goods, towards
which the Unical cannot be considered responsible.
- Put the appliance in places protected against the freezing.
- Verify the resistance of the supporting surface, taking into
consideration the weight of tank once full.
- Leave a distance of 500 mm around and on top of the tank in
order to facilitate the maintenance operations.
- It is suggested to install the tank as near to the boiler as
possible and to insulate the connection pipes in order to re-
duce the heat losses.
