How to disconnect and/or remove AF ACS B unit
In case of AF ACS B 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 B 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 B unit;
- disconnect AF ACS and reconnect another AF ACS B unit;
- make the vacuum;
- restore the refrigerant from recovery unit to the pipe and AF ACS B unit;
- disconnect the recovery unit and re-open the valves of EMX port.
In case AF ACS B 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 B unit;
- disconnect AF ACS B 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 empty the water tank
