Use only pipelines and system components which are
• clean and dry inside (free from slag, swarf, rust and
phosphate coatings) and
• which are delivered with an air-tight seal.
Depending on the compressor versions, they are sup-
plied with blanking plates on the pipe connections or
shut-off valves. These must be removed before per-
forming the strength pressure and tightness tests and
commissioning the system.
I I n n f f o o r r m m a a t t i i o o n n
The blanking plates are only designed to serve
as a transport protection. They are not suitable
as a separation between different system sec-
tions during the strength pressure test.
Mount pipelines in such a way that the compressor is
protected from flooding with oil or liquid refrigerant dur-
ing standstill. Follow the notes given in SH-170.

For systems with rather long pipelines or for
brazing operations without protective gas:
Install the suction-side cleaning filter (mesh size
< 25 μm).
A suction-side cleaning filter must satisfy the following
criteria:
• Mesh size 25 µm
• Filter with perforated metal tubes around the inside
and outside diameter
• Appropriate for bi-directional operation

Risk of compressor damage!
Generously sized filter dryers should be used to
ensure a high degree of dehydration and to
maintain the chemical stability of the circuit.
Make sure to choose a suitable quality (molecu-
lar sieves with specially adapted pore sizes).

For an optimal evacuation capacity, it is recommended
to install generously-sized, lockable additional connec-
tions on the discharge and suction sides. Sections
locked by check valves must have separate connec-
tions.

These connections lead directly into compressor areas
with sensitive mechanics. Therefore a filter must be
mounted into each pipe if the system is not manufac-
tured in serial production.

An incorrect installation may lead to a very strong vibra-

Risk of damages caused by vibrations!
Securely fasten each pipe.
Check the vibration behaviour during operation!
Fasten every pipe to the compressor by means of a re-
frigeration clamp. To do that, use the mounting holes
on the compressor, see connections on the following
pages:
14a: ECO line
14b: Liquid line for FI cooling (standard extent of deliv-
ery) and for optional LI connection
