Hydraulic Connections
Figure 5-3 Expansion Kits - Side by Side, Parallel
Figure 5-4 Expansion Kits - Side by Side, Serial
Expansion kits that are side by side in series are known to have a high pressure drop. A pressure drop calculation is recommended.
NOTICE
If using a series connection, it is strongly recommended that a calculated pressure drop be done to ensure
proper pump installation.
CONNECTION EXPANSION SET, SIDE BY SIDE, PARALLEL
Description
Set for hydraulic connection of two (2) collectors side by side. The set consists of two
(2) pieces of corrugated stainless-steel pipe with one compression ring at each end
and insulation. The headers of the left and right collectors are connected using these
corrugated stainless steel pipes. The corrugated pipe absorbs and compensates for
thermal expansion. The distance of 5.1" between the collectors must be maintained
precisely. Once the installation is complete, the insulation supplied is pulled over the
corrugated pipe and fixed in place with the adhesive tape included in the set. The
insulation is suitable for temperatures up to 347°F and resistant to UV radiation.
CONNECTION EXPANSION SET, SIDE BY SIDE, SERIES
Description
Set for hydraulic connection of two (2) collectors side by side, in series. Ready-to-fit
corrugated stainless-steel pipe (DN20) with two (2) soldered elbow joints for 22 mm
copper pipe. Used to make the connection side by side. The corrugated pipe absorbs
and compensates for thermal expansion. Rubber insulation, temperature resistant
to 347°F, is fitted on the corrugated pipe. Two (2) plugs are included in the scope
of delivery for closing the remaining header ends. The compression ring and nut are
already fitted on the collector.
