For service purposes, the pushbuttons on the main PCB need to be
accessed.  To  access  these  pushbuttons,  the  electrical  component
box  cover  does  not  need  to  be  opened.  See 

"16.1.3  To  access  the

field setting components"

 [

To  install  the  water  piping  and  field  wiring,  front  plate  B  has  to  be
removed.

13.2.2

To open the electrical component box of
the outdoor unit

NOTICE

Do  NOT  apply  excessive  force  when  opening  the
electronic  component  box  cover.  Excessive  force  can

14.1.1

Refrigerant piping requirements

NOTICE

Refrigerant  R410A  requires  strict  cautions  for  keeping  the
system clean and dry. Foreign materials (including mineral
oils  or  moisture)  should  be  prevented  from  getting  mixed
into the system.

NOTICE

The  piping  and  other  pressure-containing  parts  shall  be
suitable  for  refrigerant.  Use  phosphoric  acid  deoxidised
seamless copper for refrigerant.

▪ Foreign materials inside pipes (including oils for fabrication) must

be ≤30 mg/10 m.

▪ Temper  grade:  use  piping  with  temper  grade  in  function  of  the

pipe diameter as listed in table below.

Pipe Ø

Temper grade of piping material

≤15.9 mm
