Overview
This is an inverter heat pump condensing unit from 1.5 to 5 ton, published up to SEER2 18, with a 220V / 60Hz / single-phase supply and a 24V control interface. Air leaves the cabinet from the side, which suits pads against a wall or under a window where upward clearance is limited.
It is the outdoor half of a split system that also drives our indoor range: AHU, A-coil in three sizes, cassette, floor-ceiling and concealed ducted units are all published as pairings on one platform. It is also positioned for field replacement of aging condensing units, and is stated to adapt to multiple 24V controllers when the existing thermostat is being kept.
Where it is used
- Like-for-like replacement of a failed or aging 24V condensing unit
- New split systems with cassette, floor-ceiling, concealed ducted or AHU indoor units
- Light-commercial retrofits reusing existing ductwork with a matched coil or air handler
- Stock programmes where one outdoor platform covers several indoor types
Selection & installation notes
- 01
The family is published up to SEER2 18, but ratings are model-specific: confirm the rating and its test conditions per model on the submittal sheet.
- 02
Confirm the refrigerant with the order — R-410A and R-32 versions are published for this family and are not interchangeable.
- 03
For field replacement, check wiring at the 24V interface before removing the old unit; controller conventions and terminal labelling vary.
- 04
State the indoor unit being paired so the match, line sizes and charge are specified together.
- 05
The supply is single-phase 220V / 60Hz; verify panel capacity, disconnect and circuit protection against the model data.
Common questions
Is this a heat pump or cooling only?
It is published as a heat pump inverter unit. Heating capacity, defrost behaviour and low-ambient operation are not published at family level, so confirm them per model.
Can it replace an old condensing unit in the field?
The platform is described as replacing aging condensing units and adapting to multiple 24V controllers. Send the existing thermostat or controller model and we will confirm compatibility for that outdoor unit.
Which indoor units can be paired?
AHU, A-coil in three sizes, cassette, floor-ceiling and concealed ducted. Confirm the exact combination and refrigerant on the submittal sheet, since not every capacity covers every indoor type.
What efficiency figure applies to the model I am quoting?
Up to SEER2 18 is published for the family; ratings are determined per model, so request the figure and its test conditions before using it in a specification.
