Installation instruction
of the flat solar collectors models ES1V2.0, ES1V2.65,
ES2V/2.0 AL, ES2V/2.65
integrated in the slate roof.
ES1V/2,65, ES2V/2,65 for vertical installation
Required about 2800 mm in height and 1900 mm in width for the first
collector and + 1220 mm in width for each consecutive one. In case of
mounting a collector on the inclined roof the minimum distance between
collectors and the roof edge is 1m.

Flow resistance for collectors
3.8 Warranty conditions of the installation and use of the collectors ES2V/2.0 AL
with aluminum absorber
It is allowed to use only solar fluids that is accepted and offered by the producer, e.g.
ENSOLICOL-AL -25,
It is allowed to wash the solar thermal system and perform the leak test only with solar fluid,
The solar thermal system must be closed (hermetic):
−
the solar system can not contain automatic vents (potential place through the installation can
get into air),
−
before the first start, the solar system must be completely deaerated, and be leakproofed by
the plumber,
−
any leaks are associated with getting air into the solar thermal system with maximize the risk
of corrosion. Once air get into the solar system the solar fluid must be replaced.
It is allowed to use only connections systems that are offered by the producer,
It is recommended to do the solar system with flexible stainless steel tubes or steel tubes. It
is forbidden to connect directly the connector pipe of the collector witch any copper or brass
parts of the solar system witch increases the possibility of electrochemical corrosion.
