The maximum piping length depends on the maximum pressure availability in the water outlet pipe. Please check the
pump curves.

Anti- freezing
• When the unit is stopped during shut-off periods and the ambient temperature is very low, the water inside the pipes and
the circulating pump may freeze, thus damaging the pipes and the water pump. In these cases, the installer shall ensure
that the water temperature inside the pipes does not fall below the freezing point. In order to prevent this, the unit has a
self-protection mechanism which should be activated
• Additionally, in cases where water drainage is difficult, an anti freeze mixture of glycol (ethylene or propylene) should be
used (content between 10% to 40%). The performance of the unit working with glycol may decrease in proportion to the
percentage of glycol used, since the density of glycol is higher than that of the water.
