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.

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.
Hydraulic connection kits
The hydraulic connection kits are used to connect the collector
to the main pipework. The hydraulic connections kits
consist of two (2) flexible corrugated stainless steel pipe with
insulation, sensor well, plug and support sleeves.
Hydraulic expansion kits
The hydraulic expansion kits are hydraulic connections
between collectors in one array. The hydraulic expansion kits
consist of two (2) nipples with compression rings and unions.
Note: Hydraulic connections and expansion kits are included
with the substructure material.

302°F
Brazing ONLY, no soldering. When
brazing you must protect the stainless
steel connection to the copper to ensure
that the temperature does not rise above
302°F.
WARNING
A properly sized expansion tank must
be used to avoid damage to the Solar
Thermal System.
