Internal Condensate Removal Control

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