WINTER CONDENSATION
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 and block the flow, causing a
slow build-up of ice;
therefore special attention must be paid to eliminating
condensation, raising the unit off the ground and evaluating
whether antifreeze elements should be installed
For units with condensation trays, refer to the dimensional
diagrams to calculate the condensation discharge.
For units without condensation tray, evaluate the suitability
of placing a tray beneath the unit base.
