NOTICE

Do not block the air vents. This could affect air circulation
inside the unit.

WARNING

Provide adequate measures to prevent that the unit can be
used  as  a  shelter  by  small  animals.  Small  animals  that
make contact with electrical parts can cause malfunctions,
smoke or fire.

NOTICE

Precautions when making knockout holes:

▪ Avoid damaging the casing.

▪ After  making  the  knockout  holes,  we  recommend  you

remove  the  burrs  and  paint  the  edges  and  areas
around the edges using repair paint to prevent rusting.

▪ When  passing  electrical  wiring  through  the  knockout

holes,  wrap  the  wiring  with  protective  tape  to  prevent
damage.

NOTICE

Make  sure  to  open  the  stop  valves  after  installing  the
refrigerant  piping  and  performing  vacuum  drying.  Running
the  system  with  the  stop  valves  closed  may  break  the
compressor.

Checking the refrigerant piping

6.5.1

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.

Before checking the refrigerant piping

Make  sure  the  refrigerant  piping  is  connected  between  the  outdoor
unit and the indoor unit.

Typical workflow

Checking  the  refrigerant  piping  typically  consists  of  the  following
stages:

1

Checking for leaks in the refrigerant piping.

2

Performing  vacuum  drying  to  remove  all  moisture,  air  or
nitrogen from the refrigerant piping.

If  there  is  a  possibility  of  moisture  being  present  in  the  refrigerant
piping  (for  example,  water  may  have  entered  the  piping),  first  carry
out  the  vacuum  drying  procedure  below  until  all  moisture  has  been
removed.

6.5.2

Precautions when checking the
refrigerant piping

INFORMATION

Also  read  the  precautions  and  requirements  in  the
following chapters:

▪ General safety precautions

▪ Preparation

NOTICE

Use  a  2-stage  vacuum  pump  with  a  non-return  valve  that
can  evacuate  to  a  gauge  pressure  of  −⁠100.7  kPa
(−⁠1.007  bar)(5  Torr  absolute).  Make  sure  the  pump  oil
does not flow oppositely into the system while the pump is
not working.

NOTICE

Use  this  vacuum  pump  for  R32  exclusively.  Using  the
same  pump  for  other  refrigerants  may  damage  the  pump
and the unit.

NOTICE

▪ Connect  the  vacuum  pump  to 

both

  the  service  port  of

the  gas  stop  valve  and  the  service  port  of  the  liquid
stop valve to increase efficiency.

▪ Make sure that the gas stop valve and liquid stop valve

are  firmly  closed  before  performing  the  leak  test  or
vacuum drying.
