6.3.1

About mounting the outdoor unit

When

The outdoor and indoor unit must be mounted before the refrigerant
piping can be connected.

Typical workflow

Mounting the outdoor unit typically consists of the following stages:

1

Providing the installation structure.

2

Installing the outdoor unit.

3

Providing drainage.

4

Preventing the unit from falling over.

6.3.2

Precautions when mounting the outdoor
unit

INFORMATION

Also  read  the  precautions  and  requirements  in  the
following chapters:

▪ General safety precautions

▪ Preparation

6.3.3

To provide the installation structure

Check  the  strength  and  level  of  the  installation  ground  so  that  the
unit will not cause any operating vibration or noise.

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

Fix  the  unit  securely  by  means  of  foundation  bolts  in  accordance
with the foundation drawing.

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

6.3.5

To provide drainage

▪ Make sure that condensation water can be evacuated properly.

▪ Install  the  unit  on  a  base  to  make  sure  that  there  is  proper

drainage in order to avoid ice accumulation.

▪ Prepare a water drainage channel around the foundation to drain

waste water away from the unit.

▪ Avoid  drain  water  flowing  over  the  footpath,  so  that  it  does  NOT

become slippery in case of ambient freezing temperatures.

▪ If  you  install  the  unit  on  a  frame,  install  a  waterproof  plate  within

150  mm  of  the  bottom  side  of  the  unit  in  order  to  prevent  water
from getting into the unit and to avoid drain water dripping (see the
following figure).

NOTICE

If  the  unit  is  installed  in  a  cold  climate,  take  adequate
measures  so  that  the  evacuated  condensate  CANNOT
freeze.
