2.2.3 Refrigerant — in case of R410A or R32

If  applicable.  See  the  installation  manual  or  installer  reference  guide  of  your
application for more information.

NOTICE

Make  sure  refrigerant  piping  installation  complies  with  applicable  legislation.  In
Europe, EN378 is the applicable standard.

NOTICE

Make sure the field piping and connections are NOT subjected to stress.

WARNING

During  tests,  NEVER  pressurize  the  product  with  a  pressure  higher  than  the
maximum allowable pressure (as indicated on the nameplate of the unit).

WARNING

Take  sufficient  precautions  in  case  of  refrigerant  leakage.  If  refrigerant  gas  leaks,
ventilate the area immediately. Possible risks:

Excessive  refrigerant  concentrations  in  a  closed  room  can  lead  to  oxygen
deficiency.

Toxic gas might be produced if refrigerant gas comes into contact with fire.

DANGER: RISK OF EXPLOSION

Pump down – Refrigerant leakage.

 If you want to pump down the system, and there

is a leak in the refrigerant circuit:

Do NOT use the unit's automatic pump down function, with which you can collect
all refrigerant from the system into the outdoor unit. 

Possible consequence: 

Self-

combustion  and  explosion  of  the  compressor  because  of  air  going  into  the
operating compressor.

Use a separate recovery system so that the unit's compressor does NOT have to
operate.

WARNING

ALWAYS recover the refrigerant. Do NOT release them directly into the environment.
Use a vacuum pump to evacuate the installation.

NOTICE

After all the piping has been connected, make sure there is no gas leak. Use nitrogen
to perform a gas leak detection.

NOTICE

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

When  the  refrigerant  system  is  to  be  opened,  refrigerant  MUST  be  treated
according to the applicable legislation.
