When the outside temperature gets close to 0°C, the water
in the pipes and unit may freeze.
Frost may determine irreversible damage to the unit.
Frost damage is not covered by the warranty.
If the unit or hydraulic connections are subject to temperatures
close to 0°C:
•
mix water with glycol, or
•
safeguard the pipes with heating cables placed under the
insulation, or
•
empty the system in cases of long non-use

Consider that the use of anti-freeze solution determines an
increase in a pressure drop.
Make sure that the glycol type utilized is inhibited (not
corrosive) and compatible with the water circuit components.
Do not use different glycol mixture (i.e. ethylene with propylene).
