Internal Condensate Removal Control
Internal Condensate Removal Control (AZ6500 Only)
The Internal Condensate Removal (ICR) function will be utilized to drip the condensation, from the
base pan, onto the indoor coil to evaporate it when the compressor is running during the heat pump
operation.
During heat pump operation, the ICR system will pump condensate water from the Zoneline base pan
into a collector tray positioned above the indoor coil.
That condensate will then drain from the tray onto the warm indoor coil where it will be evaporated into
the room atmosphere. If an excessive amount of condensate water is pumped to the indoor side, the
excess amount will be routed back to the outdoor portion of the base pan.
The ICR function will be in tandem with heat pump compressor operation except in case of Reverse
Cycle Defrosting.
The ICR function will be utilized in the Class 2 mode.
