How to disconnect and/or remove Emix unit
In case of Emix is connected to a normal indoor unit port, as common use of Emix with AEI1G30EMX/GR9FI30R5IBA,
the unit must be disconnected exactly as any other air indoor unit, like hi-wall, ow ceiling, etc.
In case of Emix is connected to the EMX port and by any reason it has to be disconnected and replaced, the installer
has to do this procedure using a refrigerant recovery unit:
- close the valves of EMX port;
- connect the refrigerant recovery unit (R410A);
- recover the refrigerant inside the copper pipes and Emix unit;
- disconnect Emix and reconnect another Emix unit;
- make the vacuum;
- restore the refrigerant from recovery unit to the pipe and Emix unit;
- disconnect the recovery unit and re-open the valves of EMX port.
In case Emix must be removed de nitively:
- close the valves of EMX port;
- connect the refrigerant recovery unit (R410A);
- recover the refrigerant inside the copper pipes and Emix unit;
- disconnect Emix and reconnect the bypass disconnected during the rst installation;
- disconnect the recovery unit;
- make the vacuum on the bypass;
- open the valves of EMX port;
- switch on one of the indoor unit in cooling mode;
- connect the recovery unit to one of the liquid valve of indoor units;
- recover the refrigerant inside the outdoor unit;
- disconnect the recovery unit and be sure that the EMX port valves are open.
How to connect Emix to a solar thermal system
Emix 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 must be connected to the solar tank exactly
like any other tank in parallel to the cold and hot tap water (mixing valve); by the electric point of view Emix could be
submitted to the solar control box if it has a dry contact to enable/disable Emix energy support to the water. In case the
solar control box does not have any backup contact, Emix 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.
In case of solar panel with natural circulation, the tank of the panel is equivalent to the normal tank connected to the
Emix. Connect in parallel the cold and hot tap water is enough to make working together the solar panel and Emix, but
take care about two important matters:
- elevation between Emix and solar tank cannot be more than the 7,5 meters, the max. elevation supported by the Emix
water pump to work properly;
- higher temperature of water due by the sun in some geographical areas; if the water temperature exceeds 95°C is
better to install a security system in temperature, in order to avoid over temperature of the Emix internal components.
Domestic hot water sanitary circuit
Emix is a device using directly tap water; it is fully compliant with the European current regulation 98/83/EC about
legionella cycle and raw material in contact with tap water and it is equipped with a double wall plate heat exchanger
that give you the max. safety between refrigerant and tap water.
