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 or hose connections.The pipe system should not be fixed too close to any corners and close to Tee connectors at outlet points.

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 U-bends on the pipe. Use hose connec- tions for ∅30.

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.
