Prescriptions
Permanently cover the collectors from solar radiation starting from the first phases of the installation.
Uncover the manifolds only when loaded with glycol.
Do not fill the system with direct sunlight, possible jet of steam!
(See paragraph “Covering the collectors”).
COLLECTOR X-RAY R
THIRD TUBE AND DISTRIBUTION IN PARALLEL
The X-RAY R solar collector comes with a fully integrated third pipe in the manifold and 3 plumbing connections to
ensure equal flow distribution in each collector in the series.
Each collector has a sensor pocket on both sides so that external pipes can be connected on the right or left.
Connections regardless of number of collectors must be carried out as below:
NB
The cold pipe return must be connected to upper pipe fitting and the hot pipe flow to the lower fitting. Temperature probe must be
fitted on the same side as connections.
Reversal of connections makes temperature control impossible so system works incorrectly.
LEFT HAND CONNECTION
RIGHT HAND CONNECTION
The special feature of the X-RAY R collectors is that they can have a third integrated tube. This allows for choosing
the basic standard model of the system. The head of an X-RAY R collector has hydraulic connections on each side,
marked by dots in relief (see the figure on the right).
PUMBLING CONNECTIONS
The connections marked by one or two dots
indicate the primary circuit.
The connections marked by three dots are those
of the “third integrated tube” (if this is the chosen
standard option). For the water connections of
the solar tubing (input and return), refer to the
figures given in this paragraph.
