How to disconnect and/or remove AF ACS unit
In case of AF ACS is connected to a normal indoor unit port, the unit must be disconnected exactly as any other air
indoor unit, like hi-wall, flow ceiling, etc.
In case of AF ACS 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 AF ACS unit;
- disconnect AF ACS and reconnect another AF ACS unit;
- make the vacuum;
- restore the refrigerant from recovery unit to the pipe and AF ACS unit;
- disconnect the recovery unit and re-open the valves of EMX PORT.
In case AF ACS must be removed definitively:
- close the valves of EMX PORT;
- connect the refrigerant recovery unit (R410A);
- recover the refrigerant inside the copper pipes and AF ACS unit;
- disconnect AF ACS and reconnect the bypass disconnected during the first 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 AF ACS to a solar thermal system
AF ACS 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, AF ACS 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 AF ACS
could be submitted to the solar control box if it has a dry contact to enable/disable AF ACS energy support to the water.
In case the solar control box does not have any backup contact, AF ACS 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 AF
ACS. Connect in parallel the cold and hot tap water is enough to make working together the solar panel and AF ACS,
but take care about two important matters:
- elevation between AF ACS and solar tank cannot be more than the 7,5 meters, the max. elevation supported by the
AF ACS 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 bet-
ter to install a security system in temperature, in order to avoid over temperature of the AF ACS internal components.
(check hydraulic layouts)
Domestic hot water sanitary circuit
AF ACS 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.
