Unit installation

WARNING

Installation  shall  be  done  by  an  installer,  the  choice  of
materials  and  installation  shall  comply  with  the  applicable
legislation. In Europe, EN378 is the applicable standard.

4.1

Preparing the installation site

WARNING

The appliance shall be stored so as to prevent mechanical
damage and in a well-ventilated room without continuously
operating  ignition  sources  (e.g.  open  flames,  an  operating
gas  appliance,  or  an  operating  electric  heater).  The  room
size shall be as specified in the General safety precaution.

NOTICE

The height of the wall on the outlet side of the outdoor unit
MUST be ≤1200 mm.

Do  NOT  install  the  unit  in  sound  sensitive  areas  (e.g.  near  a
bedroom), so that the operation noise will cause no trouble.

Note: 

If  the  sound  is  measured  under  actual  installation  conditions,

the  measured  value  might  be  higher  than  the  sound  pressure  level
mentioned  in  "Sound  spectrum"  in  the  data  book  due  to
environmental noise and sound reflections.

INFORMATION

The sound pressure level is less than 70 dBA.

The  outdoor  unit  is  designed  for  outdoor  installation  only,  and  for
ambient  temperatures  within  the  following  ranges  (unless  otherwise
specified in the operation manual of the connected indoor unit):

Cooling mode

Heating mode

10~46°C DB

–15~24°C DB

4.1.2

Additional installation site requirements
of the outdoor unit in cold climates

Protect the outdoor unit against direct snowfall and take care that the
outdoor unit is NEVER snowed up.

It  is  recommended  to  provide  at  least  150  mm  of  free  space  below
the unit (300 mm for heavy snowfall areas). Additionally, make sure
the unit is positioned at least 100 mm above the maximum expected
level of snow. If necessary, construct a pedestal. See 

"4.2 Mounting

the outdoor unit"

 [

 6] for more details.

In  heavy  snowfall  areas  it  is  very  important  to  select  an  installation
site  where  the  snow  will  NOT  affect  the  unit.  If  lateral  snowfall  is
possible, make sure that the heat exchanger coil is NOT affected by
the snow. If necessary, install a snow cover or shed and a pedestal.

4.2

Mounting the outdoor unit

4.2.1

To provide the installation structure

Use a vibration-proof rubber (field supply) in cases where vibrations
may be transmitted to the building.

Prepare  4  sets  of  M8  or  M10  anchor  bolts,  nuts  and  washers  (field
supply).
