And now follow the next steps with max care:
•
Close the valves on the EMX port of outdoor unit (050, 065, 080, 110).
•
Disconnect the bypass from the valves on the EMX port (take care of it because you will need it in case of
dismount of AF ACS B unit).
•
Connect the copper pipes between outdoor unit and AF ACS B for (050, 065, 080, 110).
(warmly suggested a strong insulation in order to avoid loses of precious energy).
•
Perform the vacuum procedure.
•
Open the valves of EMX port.
•
Connect the water to the tank (It is recommended to install an expansion tank of 18 lt, service valves on the
connections of the water circuit in order to make installation and maintenance operations easier and a pipe
on the high pressure safety output of the security valve).
•
It is warmly suggested to install the filter upstream the water circuit and a softener or polyphosphate filter to
avoid limestone.
Refrigerant Circuit
AF ACS B is a component that may be connected to the other types of indoor units at the same time and without spe-
cific limitations by using the special connection for AF ACS B and duly considering the length of the AF ACS B pipe to
be added to the total length set by the outdoor unit (we advise a specific insulation of the AF ACS B pipes to guarantee
the minimum dispersion of energy).

MAXIMUM HEIGHT DIFFERENCE OUTDOOR UNIT/INDOOR UNIT:
10 m - H1, H2, H3, H4, H5
MAXIMUM HEIGHT DIFFERENCE BETWEEN INDOOR UNITS:
5 m - H
Tot L = Total length of pipes, given by the sum of pipe lengths for each indoor unit (L1+L2+L3...)
L n = Maximum pipe length per single indoor unit (n = 1, 2, 3...)
