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.
