9.4.3 Preparing the wall outlets
Whether the refrigerant lines between the indoor and
outdoor units are to be routed above or below ground, ap-
propriate and plant-specific wall outlets need to be created
through the outer wall of the building.
»
Ensure that the wall outlets are constructed in an ap-
propriate, plant-specific manner.
»
Take the construction of the wall (tiles, concrete) into
account.
»
Take the prevailing groundwater situation into
account.
Material damage
Incorrectly created wall outlets can cause signifi
-
cant damage to property, due to water (seepage,
condensation, floodwater) penetrating into the
building or stonework. Where the wall outlets are
created below ground level, the breach must be
appropriate to local conditions at the site (e.g.
non-accumulating or accumulating seepage water,
groundwater under pressure).
»
Use a suitable pipe liner or wall sleeve for the
wall outlet.
»
Tie the external end of the wall outlet in to the
external waterproof seal of the building.
»
Ensure that the pipe liner is arranged with a
slight fall (at least 2%) to the outside.
»
On both the outside and inside edge of the
wall, use appropriate ring seals to seal the
space between the wall sleeve and the re-
frigerant lines and electrical cables passing
through.
Material damage
PU foam is not suitable as a sealant for the pipe
liner.
