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:

ð

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.

WARNING

▪ Only  use  R32  as  refrigerant.  Other  substances  may

cause explosions and accidents.

▪ R32  contains  fluorinated  greenhouse  gases.  Its  global

warming  potential  (GWP)  value  is  675.  Do  NOT  vent
these gases into the atmosphere.

▪ When  charging  refrigerant,  ALWAYS  use  protective

gloves and safety glasses.

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.
