Installation site (see 

"5.1 Preparing the installation site"

 [

4

 6])

CAUTION

▪ Check  if  the  installation  location  can  support  the  unit's

weight. Poor installation is hazardous. It can also cause
vibrations or unusual operating noise.

▪ Provide sufficient service space.

▪ Do  NOT  install  the  unit  so  that  it  is  in  contact  with  a

ceiling or a wall, as this may cause vibrations.

Connecting the refrigerant piping (see 

"6.2 Connecting the

refrigerant piping"

 [

4

 9])

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

▪ Use the flare nut fixed to the unit.

▪ To  prevent  gas  leakage,  apply  refrigeration  oil  only  to

the inside of the flare. Use refrigeration oil for R32.

▪ Do NOT reuse joints.

CAUTION

▪ Do NOT use mineral oil on flared part.

▪ Do NOT reuse piping from previous installations.

▪ NEVER  install  a  drier  to  this  R32  unit  to  guarantee  its

lifetime. The drying material may dissolve and damage
the system.

WARNING

Connect the refrigerant piping securely before running the
compressor. If the refrigerant piping is NOT connected and
the stop valve is open when the compressor is run, air will
be  sucked  in.  This  will  cause  abnormal  pressure  in  the
refrigeration cycle, which may result in equipment damage
and even injury.

CAUTION

▪ Incomplete flaring may cause refrigerant gas leakage.

▪ Do  NOT  re-use  flares.  Use  new  flares  to  prevent

refrigerant gas leakage.

▪ Use  flare  nuts  that  are  included  with  the  unit.  Using

different flare nuts may cause refrigerant gas leakage.

CAUTION

Do  NOT  open  the  valves  before  flaring  is  complete.  This
would cause refrigerant gas leakage.

DANGER: RISK OF EXPLOSION

Do NOT start the unit if it is vacuumed.

Charging refrigerant (see Charging refrigerant)

WARNING

The  refrigerant  inside  the  unit  is  mildly  flammable,  but
normally  does  NOT  leak.  If  the  refrigerant  leaks  in  the
room  and  comes  in  contact  with  fire  from  a  burner,  a
heater, or a cooker, this may result in fire, or the formation
of a harmful gas.

Turn  off  any  combustible  heating  devices,  ventilate  the
room,  and  contact  the  dealer  where  you  purchased  the
unit.

Do  NOT  use  the  unit  until  a  service  person  confirms  that
the  part  from  which  the  refrigerant  leaked  has  been
repaired.

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.

CAUTION

To  avoid  compressor  breakdown,  do  NOT  charge  more
than the specified amount of refrigerant.

WARNING

NEVER  directly  touch  any  accidental  leaking  refrigerant.
This could result in severe wounds caused by frostbite.

Electrical installation (see 

"7 Electrical installation"

 [

4

 10])

WARNING

Appliance  shall  be  installed  in  accordance  with  national
wiring regulations.

WARNING

▪ All  wiring  MUST  be  performed  by  an  authorised

electrician  and  MUST  comply  with  the  applicable
legislation.

▪ Make electrical connections to the fixed wiring.

▪ All  components  procured  on-site  and  all  electrical

construction  MUST  comply  with  the  applicable
legislation.

WARNING

▪ If  the  power  supply  has  a  missing  or  wrong  N-phase,

equipment might break down.

▪ Establish  proper  earthing.  Do  NOT  earth  the  unit  to  a

utility  pipe,  surge  absorber,  or  telephone  earth.
Incomplete earthing may cause electrical shock.

▪ Install the required fuses or circuit breakers.

▪ Secure  the  electrical  wiring  with  cable  ties  so  that  the

cables  do  NOT  come  in  contact  with  sharp  edges  or
piping, particularly on the high-pressure side.

▪ Do  NOT  use  taped  wires,  stranded  conductor  wires,

extension  cords,  or  connections  from  a  star  system.
They can cause overheating, electrical shock or fire.

▪ Do  NOT  install  a  phase  advancing  capacitor,  because

this  unit  is  equipped  with  an  inverter.  A  phase
advancing  capacitor  will  reduce  performance  and  may
cause accidents.
