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.

NOTICE

Do not exceed 260 ft2 of collector area. Be aware of pressure drop (see the diagram on page 38). Use a more powerful solar pump if necessary.

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.

NOTICE

Do not exceed 260 ft2 of collector area. Be aware of pressure drop (see the diagram on page 38). Use a more powerful solar pump if necessary.

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.
