Introduction
Emix tank is the innovative indoor unit in the iSeries system range, able to provide domestic hot water from a thermo-
dynamic source all year round, i.e. independently of the system’s operating mode.
Emix tank is a new component of the iSeries system which is added to the very broad range of indoor units.
The purpose of Emix tank is to produce domestic hot water through storage, using the energy produced directly from
the heat pump (therefore renewable energy) and providing the service at the same time as heating and cooling the
environments, thanks to the various air and/or hydronic indoor units of the iSeries range.

Emix tank is both a proper heat pump tank and a full feature electrical water heater
Emix tank must be connected to an outdoor unit of the iSeries range equipped with special software and a specic
connection dedicated to Emix tank. The compatible outdoor units are all the following outdoor units of the iSeries range
with EMX port (*)

Refrigerant Circuit
Emix tank is a component that may be connected to the other types of indoor units of the iSeries range at the same
time and without specic limitations by using the special connection for Emix tank and duly considering the length of
the Emix tank pipe to be added to the total length set by the outdoor unit (we advise a specic insulation of the Emix
tank pipes to guarantee the minimum dispersion of energy).

Legionella
Legionella is a bacteria present in any water system.
The proliferation of this bacteria depends on many factors and it nds the best conditions to survive between 20º C to
45º C. Country by country, there are some different local regulation about Legionella prevention but all of them require
to heat water over than 50ºC.
Anti legionella cycle is a special operation function performed by Emix. The goal of this function is to heat all water
buffer volume. In this way, all bacteria that may have been inside the buffer would be killed.
Anti legionella cycle can not be deactivated in order to avoid health issues for end users. The cycle procedure can not
be modied, neither.
Anti legionella cycle
The anti legionella cycle is closed by one of the following conditions:
a) if the water temperature is 50º C for 2 hours continuously.
b) if the water temperature is 55º C for 30 minutes continuously.
c) if the water temperature is 60º C for 2 minutes continuously.
If within 72 hours (3 days) none of the above conditions have bee satised, automatically the water set point is moved
up to 60ºC if lower to perform the cycle. The yellow LED is switched on.
If there are electrical elements connected, they can be used during anti legionella cycle.
During the cycle, if none of the above conditions is veried and, by water temperature trend analysis, the software
understands that there is not enough energy using only the heat pump, the rst electrical element will be switched on
automatically. All the other electrical elements will be switched on every120’ checking temperature trend analysis up
to reach one of the three conditions and to close the cycle. If cycle is closed, all electric elements are switched off.
Ifafter4hoursnoneoftheaboveconditionsoccurred,thecyclewillbeconsideredNOTclosed,itwillcontinueand

Electric back up management – Booster mode
By pressing operation button until the blue led is blinking, end users can activate the booster mode. In this case the
software will manage the electric heaters under certain conditions.
If after 120’ from the start up of the system (time counter does not start when the automatic mode is set but when the
heat pump is switched on), water set point is not reached, the rst electrical element will be activated automatically.
The other steps, one by one, will be turned on every 120’ following water temperature trend, up to reach set point.
To exit the booster mode, it’s necessary to repeat the starting procedure.
Electric back up management – Super Booster mode
By pressing operation button until yellow led is turned on (3 beeps will be listened when the button will be released),
end user can activate the super booster mode. In this case all electric elements connected are switched on in one shot,
together with the heat pump. When water set point is reached, all heaters are switched off.
To exit super booster mode, it’s necessary to repeat the starting procedure.
This option is very useful when it’s necessary to heat the water as soon as possible.
Electric back up management – Automatic modes
Emix tank software can automatically manage electric back up heaters under certain conditions. This mean that these
operation modes are not to be set and that can not be deactivated.
They are:
- Antifreeze mode
- Cold draft prevention
- Electric water heater mode
Electric back up management – Antifreeze mode
If water temperature inside the buffer tank is lower than 10° C, all electric elements connected are switched on. When
the water temperature reaches 11° C all the elements are turned off.
Electric back up management – Cold draft prevention
If water temperature is lower than 40º C and one or more indoor units is in cold draft condition, one by one electrical
element are switched on per time (every 10’) and switched off all together when water temperature reaches 50º C and
no cold draft condition on any indoor unit is detected.
Electric back up management – Electric water heater
If the outdoor unit is stopped for maintenance of end user’s decision (no communication), Emix tank unit could be used
as controller of the electrical heater elements located inside the tank, exactly like any electric water heater. In this case,
if the water temperature is lower than the desired temperature for more than 30’, all the connected electrical heaters will
switch on up to the reaching of the setpoint. End users can switch off Emix tank if they do not want to have this option.

How to disconnect and/or remove Emix tank unit
In case of Emix tank is connected to a normal indoor unit port, as common use of Emix with G30, the unit must be
disconnected exactly as any other air indoor unit, like hi-wall, ow ceiling, etc.
In case of Emix tank is connected to the EMX port and by any reason it has to be disconnected and replaced, the in-
staller has to do this procedure using a refrigerant recovery unit:
-closethevalvesofEMXport;
-connecttherefrigerantrecoveryunit(R410A);
-recovertherefrigerantinsidethecopperpipesandEmixtankunit;
-disconnectEmixandreconnectanotherEmixtankunit;
-makethevacuum;
-restoretherefrigerantfromrecoveryunittothepipeandEmixtankunit;
- disconnect the recovery unit and re-open the valves of EMX port.
In case Emix tank must be removed denitively:
-closethevalvesofEMXport;
-connecttherefrigerantrecoveryunit(R410A);
-recovertherefrigerantinsidethecopperpipesandEmixtankunit;
-disconnectEmixtankandreconnectthebypassdisconnectedduringtherstinstallation;

-connecttherecoveryunittooneoftheliquidvalveofindoorunits;
-recovertherefrigerantinsidetheoutdoorunit;
- disconnect the recovery unit and be sure that the EMX port valves are open.
How to connect Emix tank tank tank to a solar thermal system
Emix tank tank could be connected to any type of thermal solar system, both natural and forced circulation.
In case of forced circulation solar system, by the water point of view, Emix tank tank must be connected to the solar
tankexactlylikeanyothertankinparalleltothecoldandhottapwater(mixingvalve);bytheelectricpointofviewEmix
tank tank could be submitted to the solar control box if it has a dry contact to enable/disable Emix tank tank energy
support to the water. In case the solar control box does not have any backup contact, Emix tank tank will run in parallel
mode with the solar system and obviously will stop immediately the operation if the water is already hot by the sun.
