ENGLISH
From factory the unit is supplied and set with a pre-charge of nitrogen gas
(insert gas). Therefore, all insert gas must be purged before connecting the
assembly piping.
Unscrew the pinch pipe at the end of each refrigerant pipe.
Result
: All inert gas escapes from the indoor unit.
Note
To prevent dirt or foreign objects from getting into the pipes
during installation, do NOT remove the pinch pipe completely until
you are ready to connect the piping.
CAUTION
Connect the indoor and outdoor units using pipes with flared
connections(not supplied). For the lines, use insulated,
unwelded, degreased and deoxidized copper pipe,(Cu DHP
type to ISO 1337), suitable for operating pressures of at least
4200kPa and for a burst pressure of at least 20700kPa. Copper
pipe for hydro-sanitary applications is completely unsuitable.
For sizing and limits (height difference, line length, max. bends,
refrigerant charge, etc.) see the outdoor unit installation
manual.
All refrigerant connection must be accessible, in order to
permit either unit maintenance or removing it completely.
Purging the unit
The designs and shape are subject to
change according to the model.
