USER AND MAINTENANCE
INSTRUCTIONS
2.1 CLEANING AND MAINTENANCE.
Attention:
to preserve integrity of the storage tank unit and keep
the safety features, performance and reliability, which distinguish
it, unchanged over time, you must at least execute maintenance
operations on a yearly basis in compliance with what is stated in
the relative point at “annual check and maintenance of the appli-
ance”, in compliance with national, regional, or local standards in
force. Annual maintenance is essential to validate the Immergas
warranty. We recommend stipulating a yearly cleaning and main-
tenance contract with an authorised local firm.
2.2 FUNCTIONING.
This storage tank allows easy provisioning of water for domestic
use and industrial use.
The storage tank is connected to the water distribution network via
the cold water fitting and to the utilities via the hot water fitting.
If a utility withdraws hot water, the cold water enters the tank
where it is heated to the temperature set on the thermostat.
It is recommended to adjust the temperature between 60 and 65°C
because this temperature guarantees the best performance of the
storage tank unit and at the same time ensures:
- maximum hygiene
- maximum affordability
- delay in lime scale formation
The DHW in the storage tank is heated with the passage of CH/
solar water, which circulates inside the coils inside the storage
tank unit itself.
In all cases the maximum temperature inside the storage tank unit
must not exceed 99°C.
2.3 EMPTYING THE STORAGE TANK UNIT.
To drain the storage tank, use the special draining valve in the
lower part of the storage tank.
Before draining, ensure that the DHW inlet valve is closed.
2.4 CASE CLEANING.
To clean the outer parts of the storage tank, just use a cloth damp-
ened with product suitable for the purpose that can be found on
the market. Abrasive, solvents, petrol and alcohol products are
not recommended.
2.5 DECOMMISSIONING.
In the event of permanent shutdown of the storage tank, contact
an authorised company for the relative operations, among other
things making sure that water supply is disconnected.
At the end of its service life the appliance must not be disposed of
like normal household waste nor abandoned in the environment,
but must be removed by a professionally authorised company.
Contact the manufacturer for disposal instructions.
