The condensation drainage system must be set up with an ade-
quate inclination to make sure the water comes out properly.
Hereunder are the guidelines to set up the condensate drain
correctly.
All water batteries (including the additional one), are equipped
with an air vent valve near the upper connection, and with a
water drain valve near the lower one. All the valves can be adju-
sted with a screwdriver or hex key.
Once installation is complete:

• Bleed the air contained in the circuit.
• Make sure that there are no water leaks.
• Coat the valve and connection pipes with 10 mm thick anti-
condensation material or install the auxiliary pans.
• Pour water into the condensate collection pan and check that
the liquid is drained regularly, following the route up to the
condensate drain outlet. Otherwise, check the inclination and
look for possible blockages.
