4.8.3 Installation of buried connecting pipework
When using buried connecting pipe-
work, an
installation shaft must be
constructed at the connecting point of
the refrigerant and the evaporator for
the Models AIR 80 C13A and AIR 80
C22A.
The diameter of the shaft must be a
minimum of 1.5m and its height must
be a minimum of 1.2 m (2 rings and a
cone). If the collection shaft that is
sized too small, OCHSNER customer
service will not commission the system
(safety at work)!
All brazing points on the copper con-
nection pipework must be accessible
for servicing all-year-round (F-gas
regulation).
Preparations for the system installer:
-
Correct construction of the wall conduit
through the cellar wall for the lined conduit
(min. D=200 mm).
-
Dig out a channel between the cellar wall and
the installation shaft (max. 4m clearance due
to 5m copper pipework length)
-
Construct installation shaft
-
Construct evaporator foundation
-
Fix evaporator to foundation
-
Lay lined conduit sloping towards the installa-
tion shaft

It is essential with the heat pump AIR 80 C22A
that the liquid and suction gas pipework is sym-
metrically distributed to both evaporators (see
Section 4.8.4). An appropriate arrangement of
the evaporator connections to the installation
shaft is therefore essential for ground-based
connection pipework.

pipework with the installation shaft with AIR 80 C22A.

Work to be carried out by OCHSNER customer
service:
-
Soldering the copper pipework knee
-
Solder a vertical copper pipe to the copper
knee
-
Complete the connection with the evaporator
-
Fit the insulation
Once all the work on the connections has been
completed and the pipework has been seal tested
by means of a pressure test, the channel with the
lined conduit can be filled with suitable bulk ma-
terial.
