Facet the inside at the end of the neatly cut hose, using a sharp
knife (faceting: 1 / 3 hose thickness, 45°).
→
Prior to the installation, it is recommended to lubricate the contact
points on the hose nipples and the hose well with glycerin
(see "Recommended auxiliary materials", page 12). Caution:
Only use glycerin if it is safe for the application.
→
Insert the faceted hose all the way into the hose nut (4). For this
purpose, if may be necessary to use a device and/or press.
CAUTION:
Risk of injury from improper installation.
• Installation and construction of the device may be carried out by
trained personnel only and in consideration of the safety standards.
→
Use a ball-point pen to mark the point where the hose protrudes
from the hose nut. This marking is important to measure how far
the hose extends by the clamping.
→
Slide the union nut (2) over the hose nipple (1) and secure with the
retaining ring (3) (this step is only required for couplings with union
nut).

Check marking on hose. It should be located approx. 5 mm away
from the beginning of the hose nut. In case this guide value is
exceeded considerably, there is a risk that the hose no longer sits
far enough in the connection.
In this case, removal and a new installation have to be carried out.
6.3. Installation of the connections sterile
standard with half nuts
WARNING!
Danger of bursting caused by damaged or incorrectly installed
hoses.
