Refrigerant lines
6. Refrigerant lines
6.1 Preparing the refrigerant lines
Note
Only OCHSNER customer service or authorised
OCHSNER customer service partners may con-
nect the refrigerant lines to the indoor and outdoor
units.
Note
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.
Note
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.
Note
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:
»
Keep the distance between the indoor and outdoor
units to a minimum to prevent heat loss from the re-
frigerant pipes.
»
Select the installation sites for the indoor and outdoor
units so that the maximum permissible line lengths
and height differentials are observed.
»
Avoid routing the lines in the vicinity of rooms that are
sensitive to sound (e.g. bedrooms). The refrigerant in
the lines can generate noise under certain operation-
al conditions.
»
Use the largest possible bending radii to avoid high
pressure losses.
6.1.1 Line lengths
»
Observe the maximum permissible line lengths for
the refrigerant lines.
»
Observe the maximum permissible height differential
between the indoor and outdoor units.
