– Uncover the collectors and clean the glass by removing all the
informative stickers.
– Check that there are no leakages and make sure that the pi-
pes connecting the collectors and the calorifiers, as well as the
cold and hot water pipes, are adequately insulated to prevent
heat losses and to protect them against frost.
– Once the installation has been completed, the system must be
left for 24 hours without using hot water and only then can the
closed circuit be operated.
The
ANTI-FREEZE LIQUID
is a product based on propylene glycol
capable of guaranteeing effective heat-transfer properties at
both high and low temperatures.
It is non-toxic and protects up to –37°C (55% volume/volume so-
lution with water).
It is specifically designed for offering excellent anti-corrosion
properties.
In watery solutions, the anti-freeze liquid protects in relation to
its degree of dilution, as shown in the table below.

– To connect the heating element to the mains, a power cable
with 3x4 mm² cross-sectional size (for a 4 kW heating element)
is required (Drawing 2).

– Pass the end of the cable through the seal and towards the
electrical components.
– Connect the black wire (live) to the L connector and the blue
wire (neutral) to the N connector on the thermostat. Connect
the yellow wire (earth) to the small M4 screw present on the he-
