1 - SYMBOLS USED IN THIS MANUAL
When reading this manual particular care has to be given to the parts marked with the followings symbols:
NOTE!
Suggestions
for the user
WARNING!
Indicates a potentially dangerous
situation for the product and the
environment
DANGER!
Indicates serious danger
for your personal safety
and for your life
2 - A CORRECT USE OF THE APPLIANCE
The INOXIA GJ appliance has been designed utilizing today’s heating technology 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 pumped hot water central heating systems and for the
production of domestic hot water.
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 foreseen scopes it is necessary to carefully follow the
instructions indicated in this manual.
3 - WATER TREATMENT
• The hardness of the mains water supply conditions the frequency with which the DHW 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.
