14. inertial storage tank
The accumulation tank is necessary in the event of the following:
• the water in the system is very low
• the unit will not be used in a private house (in an industrial process or other)
WATER CIRCUIT EMPTYING
The unit is equipped with outlets for the pump emptying and storage.
Outlets are accessible from the rear side (left side in the figure).
Storage content: size 82÷122 80 litres
(optional) size 162÷302 130litres
RECOVERY EXCHANGER
OPTIONAL - The unit can be equipped with exchangers to
recover the condensation heat.
The recovery can be:
PARTIAL
• with 25% recovery
• The customer is responsible for the management of the
circulation pump, valves, thermostats, etc
The recovery input water must not be below 25°C, in the
event that, wrongful operations and breakages of the unit
can occur .
Water connections must be performed carefully as for the
evaporator (filter, circuit washing, etc) .
Perform all necessary interventions to avoid the RISK OF
FREEZING (tubes insulation, emptying of circuit, addition of
glycol, anti-freeze heaters) .
Water temperature can reach high temperatures (up to
100°C), therefore:
• avoid the RISK OF BURNS by adopting the necessary
precautions (insulation of tubes, temperature detecting
station on water if the sanitary use is foreseen, etc)
• Install safety valves and specifically dimensioned
expansion tanks in the hydraulic circuit.
