Quick Facts:
- 27,000 BTU, 25 SEER2 multi zone heat pump condenser
- Designed to function with up to 4 attached air handlers
- Efficient cooling from -13°F to 122°F outdoor temperatures
- Efficient heating from -13°F to 75°F outdoor temperatures
- Gold Fin full-protection coating on condenser coil
- Quiet operation at even the highest workloads
27,000 BTU, 25 SEER2
The 27,000 BTU, ES-27Z-M4C is designed to easily support up to 4 air handlers at up to 1.25 times the condenser BTU rating, or 33,750 BTU across all air handlers. This adaptive, inverter condenser is constantly self-adjusting to provide the precise amount of heating or cooling needed to maintain your desired temperature in each room or zone. You can set different temperatures room by room, even turn off heating and cooling in unused areas. This, combined with a high efficiency rating of 25 SEER2, means you are buying a system designed to intelligently save you money both up front and over the lifetime of the unit.
Although the condenser is pre-charged, please note that this model of equipment does not have quick connect line set connectors and is not a self-install unit. You will need a professional to add more refrigerant and vacuum the lines as needed. Installation materials such as line sets, control wire, drain hose, whip and disconnect are not included, but are available at additional cost in the Accessories section to the right of this text. For all multi zone ACiQ condensers, a minimum of two air handlers is needed for the unit to function.
Self Cleaning Condenser
ACiQ condensers stay clean and efficient with self-cleaning technology built right in. At the end of each cycle, the fan reverses direction and blows air out the back of the unit — helping remove leaves, dirt, and debris before buildup can begin.
9,000 BTU Ceiling Cassette ACiQ Mini Split Air Handler| R454B
Mini Split systems are great, but what if you don't want the air handler on your wall? ACiQ offers the ACIQ-09CC-HH-MC ceiling cassette air handler for customers who want a more hidden appearance and more centralized air distribution. Ceiling Cassette air handlers provide the same high-efficiency heating and cooling of a regular wall-mounted unit, and come with an included hand-held remote control. Once the ceiling cassette is mounted in the ceiling, only the grille is visible for the most understated appearance.
Installation Considerations
Ceiling Cassettes are flush-mounted, which requires removal of enough ceiling material to create a cavity for the unit. These units will fit between 24 on-center joists, but are too large to fit between 16 on-center joists without modifying the structure of your framing. Additionally, Ceiling Cassettes have factory-installed, onboard pumps to lift the condensation produced by the unit during cooling. The pump can lift the condensation up to 14. From there, it will be necessary to construct a PVC drain system to route the condensation to a safe wastewater location. Refrigerant and wiring connections are the same as the wall mounted units.
Features:
- 9,000 btu of Heating or Cooling
- Dry and Fan modes also available
- Good for a small room in most climates
- 4 Way Air Supply for consistent room coverage
- Handheld remote included
- Decorative Grille included
- Built-in condensate pump

Quiet Comfort
Every ACiQ system is precision engineered to quickly achieve set temperature and hold it there, no matter what the weather is outside. With whisper quiet indoor and outdoor units, ACiQ never intrudes on your peace and quiet.
