1 Where the pipe liner has two 90° bends, it must be
laid together with the refrigerant lines.
2 If the pipe liner is laid empty, it will not be possible to
insert the refrigerant lines afterwards.
»
For the underground pipe liner, use rigid waste pipes.
»
Use a pipe liner of a suitable diameter for the sys-
tem-specific refrigerant lines and the planned pipe
bends (see „Foundations for the outdoor unit“ on
page 14).
»
For 90° bends in the pipes, use either 3x 30° bends
or 6x 15° bends (depending on the diameter of the
pipe liner and the depth at which it is laid).
»
At the point where the refrigerant lines are connected
to the outdoor unit, create a suitable trench.
»
Dig a straight trench between the wall outlet and the
trench at the outdoor unit.
»
Lay the pipe liner, with the refrigerant lines already
inserted, into the trench between the outdoor and in-
door units.
»
Lay the electrical control leads and power supply
cables in a suitable electrical conduit. The optional
OCHSNER cable harness is suitable for laying direct
into the ground.
»
Allow some surplus length in the refrigerant lines
between the connections at the indoor and outdoor
units.
»
Ensure that the wall outlets are appropriate and
plant-specific, and that the pipe liner is appropriately
sealed.
»
Ensure that the open end of the pipe liner at the
outdoor unit is properly sealed. For sealing the re-
frigerant lines in the pipe liner, use for example an
appropriate ring seal or a UV-resistant, permanently
flexible sealing compound.
»
Any exposed refrigerant lines outside the pipe liner
must also be protected from a build-up of condensa-
tion with appropriate insulating material. Out of doors,
the insulating material must also have UV protection.

Information
Insulation used beneath the soil must be made of
a closed-cell material. Otherwise, the thermal in-
sulation of the material will be impaired.
Material damage
PU foam is not suitable as a sealant for the pipe
liner.
