We recommend the use of a directly applicable mixture of water and gly-
col with corrosion inhibitors. Avoid increasing the concentration by large
amounts; it should never exceed 50% because this would create a mixture
-35
with very high viscosity levels, thereby reducing the heat-transfer properties
of the fluid. DO NOT mix with any other fluids.

Although this fluid is non-toxic, odourless and biodegradable, it
should be handled with caution. The use of chemical-resistant glo-
ves and eye protection is recommended when handling this fluid.
If the fluid comes into contact with the skin, wash with soap and
water. In case of contact with the eyes, rinse immediately with
plenty of clean running water.

COLLECTOR INSTALLATION

The collectors can be arranged in rows of up to 10 collectors
connected in parallel (harp and meander collector models). The
maximum number of panels which can be connected in series
will depend on the climate in the region where they are installed
and the legislation applying in each region. We recommend that
the collectors used to form the solar system be of the same
model, both for energy and construction reasons.
If more than one row is required, the collectors must be installed in a
multiple parallel arrangement, preferably with the same number of co-
llectors in each row, as illustrated in the image. Cut-off elements will be
installed to separate each row. A safety air vent valve will be installed in
each row; if an automatic air vent valve is used, a cut-off valve will be
installed to disable the valve while the system is in operation. We must
also ensure that there are no reverse flows, as doing so will prevent
energy losses.
Collector connection
The optimal connection of harp and meander collectors (parallel con-
nection) is by crossing over the row of input and output collectors from
opposite ends; they can be also connected from the same end of the row
of collectors with barely any loss of performance.
The connection of simple meander collector models (serial connection) is
performed as shown in the figures below:
