4.4 Condensate water
When a heat pump is running it produces a considerable amount of water due to the defrosting cycles of the external coil.
The condensation must be eliminated in a manner to avoid wetting pedestrian areas.
With extensive very cold outdoor temperatures, condensation could freeze outside the unit blocking the ow and causing a slow build-up of
ice; therefore special attention must be paid to eliminating condensation, raising the unit o the ground and evaluating whether antifreeze
elements should be installed.
