2

Connect  the  gas  stop  valve  from  the  outdoor  unit  to  the  refrigerant  gas
connection of the indoor unit.

NOTICE

It  is  recommended  that  the  refrigerant  piping  between  indoor  and  outdoor  unit  is
installed in a ducting or the refrigerant piping is wrapped with finishing tape.

INFORMATION

When the indoor unit is installed in a place with limited space, an optional pipe bend
(EKHVTC) kit can be installed to facilitate the connection to the refrigerant gas and
liquid connections of the indoor unit. For installation instructions, see the instruction
sheet of the pipe bend kit.

8.3 Checking the refrigerant piping

8.3.1 About checking the refrigerant piping

The outdoor unit's 

internal

 refrigerant piping has been factory tested for leaks. You

only have to check the outdoor unit's 

external

 refrigerant piping.
