Transport. Handling.
Collectors are packed in cardboard or with stretch film, carton on glass surface and hard polystyrene
on the corners and must always be transported in vertical position.
Palletizing of collectors. Upon request special pallets for horizontal packaging are available.
Scheme 2
During installation, keep the upper carton or plastic film in place up to the moment the circuit is filled
with thermal fluid.

Collector protection against lightning
Use a copper wire 16 mm² to connect the collectors (metal parts) with lightning protection system if
existing or earth them to an earth rod using wire of the same size. The route of this wire should be
always outdoors. Ask specialist for more information.

COLLECTORS INTERCONNECTING IN A FIELD WITH 20m²
For collectors PK SL AL -2,00 m² and PK SL AL -2,4m ², the optimal arrangement is in five arrays
connected in parallel with maximum two collectors in each array connected in series. For
Mediterranean countries, all collectors must be connected in parallel to prevent over heating as
much as possible during summer. Use brass joints for copper tube Ø 22 and copper tubing
properly insulated to make all connections.
Collectors are delivered bare copper tube Ø 22 without any threading or union nuts.

ATTENTION: When screwing the connection fittings of the collectors (plugs, raccords, connectors,
etc.) use divert force to avoid damaging the header tube connections inside the collector.
