5.2 Connecting the refrigerant piping
DANGER: RISK OF BURNING/SCALDING
CAUTION
▪ No brazing or welding on site for units with R32
refrigerant charge during shipment.
▪ During installation of the refrigeration system, joining of
parts with at least one part charged shall be performed
taking into account the following requirements: inside
occupied spaces non permanent joints are not allowed
for R32 refrigerant except for site made joints directly
connecting the indoor unit to piping. Site made joints
directly connecting piping to indoor units shall be of non
permanent type.
CAUTION
Do NOT connect the embedded branch piping and the
outdoor unit when only carrying out piping work without
connecting the indoor unit in order to add another indoor
unit later.
5.2.1 Connections between outdoor and indoor
unit using reducers
INFORMATION
▪ For the DHW generator for Multi use the same reducer
as for the 20 class indoor unit.
▪ For the Hybrid for Multi, see the indoor unit installation
manual for the capacity class and applicable reducer.
