1.7.6 Mounting requirements and hints
Temperature compensation
When hot water (max. 75°C) is used in the system due regard should be paid to thermal expan- sion of the pipes when mounting the system. When raising the temperature from10°C to 75°C the system will expand some 0.7 mm/m. In order to allow for this expansion long straight lines should be fitted with compensators in the form of
U-bends/hose connections
At a max. temperature on the system of 75°C a compensator should be fitted at 20 m intervals if there are no elbows on the line. If the pipe may expand at one end compensators may be left out if the pipe is not fixed at the Tee connectors at the same time. Compensation for ∅15 and ∅22 should be in the form of hose connections or as
COMPENSATION
Pipe | Hose no. | Hose no. stainless | L (mm) | L min (mm) | R min (mm) |
∅15 | 6300453 | 6301191 | 350 | 450 | 40 |
∅22 | 6300453/6300454* | 6301191/6202161* | 350/480 | 550 | 55 |
∅30 | 6300454 | 6202161 | 480 |

*If the pipe line carries more than the water volume from 3 pumps 6300454 respectively 6202161 hoses should be fitted.
