CONNECTION EXPANSION SET, STACKED COLLECTOR IN SERIES

Description

Set for hydraulic connection of two collectors stacked, in series. Ready-to-fit corrugated stainless-steel pipe with two (2) soldered elbow joints for .86" copper pipe. Center-to- center distance 9 1/4". The collector outlet of the lower collector is connected to the inlet of the upper collector. The corrugated pipe absorbs and compensates for thermal expansion. Rubber insulation, temperature-resistant to 347°F, is fitted on the corrugated pipe. Two 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 for the collectors connected in this way. Be aware of pressure drop (see the Recommended Flow Chart on page 38). Use a more powerful solar pump if necessary.
