Refrigerant lines
CAUTION: Risk of slipping
If drainage for condensation is inadequate, ice can
build up in winter in the area around the outdoor
unit.
»
Ensure drainage for condensation is sufficient
even at low temperatures.
»
Ensure that no ice is formed, especially on
paths and entrances around the outdoor unit.
Information
Insulation used beneath the soil must be of a
closed-cell material construction. Otherwise, the
thermal insulation value of the material will be im-
paired.
5.4 Sound
Please note the following with regard to sound emissions
from the outdoor unit:
► Avoid installing on reverberant flooring.
► Avoid installing between two building walls or in cor-
ners. Walls can increase the noise level.
► Avoid placing the unit directly below or next to rooms
that are sensitive to sound (e.g. bedrooms).
Information
Plants and cultivated areas around the outdoor
unit, subject to minimum clearances, can reduce
its noise level.
Information
The maximum permitted sound levels are partly
subject to legal limitations.
»
Observe all applicable national and regional
regulations and provisions.
6. Refrigerant lines
6.1 Preparing the refrigerant lines
Information
Only OCHSNER customer service or authorised
OCHSNER customer service partners may con-
nect the refrigerant lines to the indoor and outdoor
units.
Information
If the appliance, the refrigerant lines, the pipe
fixings and the wall conduits are not installed cor -
rectly, structure-borne sounds can be transmitted
to the building.
»
Ensure that the refrigerant lines are in-
stalled in a way that ensures insulation from
structure-borne noise. The system installer
carrying out the work is responsible for this.
»
Never lay the refrigerant lines in a bricked-in
sleeve tube. Noise transmission to the living
space is unavoidable when bricked-in sleeve
tubes are used, due to the resonating body
effect.
»
Use insulating refrigerant pipe clamps for ver-
tical installation of the refrigerant lines. The
distance between the refrigerant pipe clamps
must not exceed 1.25 m.
Material damage
Thin-walled pipes are at risk of bursting.
»
Only use copper pipes suitable for refrigerant
(EN 12735-2).
Material damage
Dirt and contamination in the refrigerant lines can
result in a clogged expansion valve or compressor
damage.
Incorrect or premature opening of the refrigerant
connections can allow dirt and moisture to enter
the refrigerant circuit.
»
Only use copper pipes suitable for refrigerant
(EN 12735-1).
»
Do not open the connections on the indoor
and outdoor units.
»
Ensure that no dirt enters the refrigerant
pipes.
Information
Systems with incorrectly sized refrigerant pipes
cannot be commissioned.
»
Observe the machine-specific dimensions for
the refrigerant pipes.
The refrigerant connections (suction gas and liquid lines)
on the indoor and outdoor units are supplied soldered
closed.
Information
Appropriate copper pipes for refrigerant lines are
supplied sealed at both ends and filled with nitro -
gen.
Please note the following with regard to routing of the re-
frigerant pipes:
