2 Determine which graph or table to use.
▪ For indoor units: Is the unit ceiling-mounted, wall-mounted or
floor-standing?
▪ For outdoor units installed or stored indoors, and field piping
in unventilated spaces, this depends on the installation
height:
If the installation height is... Then use the graph or table for...
<1.8 m
1.8≤x<2.2 m
≥2.2 m
3 Use the graph or table to determine the minimum floor area.

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 may be produced if refrigerant gas comes
into contact with fire.
