5.5 Connecting the hose lines
See chapter "Application example" for an example of how to route the hoses
from the product to the tank.
 Verify that the hoses are resistant to the stored liquid and its vapours.
1. Use oil- and water-resistant plastic hoses 6 x 2 mm for the measuring line
(red), the suction line (transparent) and the pressure line (transparent).
2. In outdoor or underground applications, install the hoses in suitable liquid-
tight, shock-resistant and weather-resistant protective pipes.
3. The hose lines must have the full cross section over the entire length;
there must be no bends and indentations.
4. Do not install any shut-off fittings.
5. During mounting, secure all transition and connection points of the hose
lines by means of hose clamps.
You may also use quick-action couplings (shutting off at one end, for exam-
ple, nominal diameter 7.2, Rectu Base type 26) at the tank side of the pres-
sure line and the measuring line of the interstitial space. The following condi-
tions apply to this:
• The coupling part with the shut-off element is directly and permanently
mounted to the tank.
• The connection piece for the pressure line and the measuring line is
secured by means of one hose clamp for each hose.
• The pressure line and measuring line must be mounted and connected in
such a way as to prevent twisting.
Quick-action couplings enable factory-filling of the interstitial space with dried
air which considerably reduces the time required on site for commissioning.
The following must ensured:
• Only dried air may be in the interstitial space.
• The coupling part at the tank end must be clean.
