48,000 BTU, 21 SEER
The 48,000 BTU, ACIQ-48z-HH-M6C is designed to easily support up to 6 air handlers at up to 1.25 times the condenser BTU rating, or 60,000 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 23 SEER, 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.
Extreme Heat Base Pan Heater Technology
Each ACiQ condenser has integrated Extreme Heat technology to maximize heat performance in extreme cold weather. Extended heat pump performance (HyperHeat) harnesses the power of inverter condenser with outdoor temp sensing, variable refrigerant flow and variable condenser fan speed to maximize heat extraction all the way down to -22°F. Plus, every Extreme Heat ACiQ condenser includes a base pan heater to keep ice from collecting on the condenser coil during heat pump operation.
Quality Construction
State-of-the-Art manufacturing is behind every ACiQ product, resulting in quiet, effective operation over a long service life. Most models have low ambient heating and cooling.
Highest Efficiency
ACiQ saves you money up front, but also over time by reducing energy bills. Every ACiQ condenser features a variable inverter twin rotary compressor, lowering wear and increasing performance. Compare specs against other brands in the same price category, and you will agree, ACiQ is the best value.
Longer life, longer warranty
Intelligent design goes into every element of ACiQ’s manufacturing ensuring flawless performance for years. Low friction, variable inverter twin rotary compressors give bulletproof reliability. Register equipment at ACiQ.com to extend warranty protection to 7 years parts, 12 years compressor.
Installation and Maintenance
ACiQ multi zone condensers are pre-charged with R410-A refrigerant for 25' per air handler connection. In many cases, no additional refrigerant is needed. All units are run-tested at the factory for years of trouble-free performance. Troubleshooting is easy thanks to unit's self diagnosing control board with alerts that are sent to each connected air handler.
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 ACIQ Platinum Single Zone Floor Mount Mini Split Air Handler - R454B | 230V
ACiQ Floor Mounted air handlers are ideal for sun porches and attic rooms where space to mount a standard high wall unit is not available. Sometimes called a heat console type air handler, these units surface mount low on the wall, near or on the floor. The shape is wider, taller and slightly shallower than the high wall unit. These are ideal for sun porches where the only wall space is below windows, or attic remodels with knee-walls, where vertical high walls may not be available.
Optimized for Heat
Like a high wall mount, these units take in return air at the top edge and deliver it at the bottom. This is ideal for heating. By delivering warm air at floor level, stratification due to heat rise is eliminated. When you put the unit into cooling mode, the airflow direction is reversed for better air mixing in the room.
Features
12,000 BTU of Heating or Cooling
Dry and Fan modes also available
Good for a small room in most climates
Remote control thermostat included
Note: The 18k and 24k are slightly different in appearance from the 12k, and can be surface mounted on the floor or ceiling. Please see the appropriate manual for your model.
18,000 BTU ACIQ Platinum Single Zone Floor Mount Mini Split Air Handler - R454B | 230V
ACIQ Floor Mounted air handlers are ideal for sun porches and attic rooms where space to mount a standard high wall unit is not available. Sometimes called a heat console type air handler, these units surface mount low on the wall, near or on the floor. The shape is wider, taller and slightly shallower than the high wall unit. These are ideal for sun porches where the only wall space is below windows, or attic remodels with knee-walls, where vertical high walls may not be available.
The ACIQ-18FM-HH-MB and ACIQ-24FM-HH-MB creatively solve various installation issues.
Unlevel Surfaces: The pitch of the roof is often reflected indoors as well, providing angled surfaces that make mounting traditional air handlers impossible. This system uses threaded rod to allow the air handler to be level, even when the walls are not. The threaded rod can be adjusted to accommodate all geometry angles, allowing the system to touch the ceiling or hang several feet below it
Uninsulated Roofs: The cassette and concealed duct air handler systems want at least a foot of space between the ceiling and the roof, this unit can work with a gap as small as one inch, which is what you often see with metal buildings and 3 season rooms. The air handler will be located near the edge of the room, blowing towards the opposite edge of the room, which is different than a cassette system, that blows air in all directions and is located in the center of a room. Sun Rooms: The air handler is actually mounted directly to the wall, fitting perfectly under the windowsill, elevated about 2 inches from the floor, even thou this is referred to as a floor mounted air handler, there is no need to drill or modify the floor as all connections can go thru the wall. Perfect for rooms that are mostly windows, these units pull air from the bottom and blow the air upwards, allowing heating the room in winter and automatically shutting off when the large windows are opened during the summer with the optional door-open sensor.
Floor Installation: The unit can be mounted to the floor when drilling holes into the wall is highly undesirable, as it common with brick/marble surfaces. The refrigerant/electrical/drain line can be run thru the floor and entirely hidden from view. The system is pre-wired for a 240vac condensate pump with over-flow shutoff connections.
Note: The 18k and 24k are slightly different in appearance from the 12k, and can be surface mounted on the floor or ceiling. Please see the appropriate manual for your model.

Happy customer
Excellent. Placed unit in a two room cabin with each inside unit on the same common wall. Outside temps were in the low 40’s and the cabin was quickly warmed.

We have these in our apartment
This is a good air conditioner for the price. Our apartment living room and kitchen have been kept nice and cool. The complex we moved into actually already had these installed but I have been so happy with the performance I purchased one for my mom who lives in a tiny home, I'm an HVAC tech and it was about time to replace her HVAC. Yes, I recommend this.

Hotel cold at home 🤭
We have zero regrets! No wait, one. That we didn’t get them sooner! We (my husband, self and 19yr old son) work outside noon-8am several days a week in Texas. It doesn’t matter how low you set your AC unit it’s just never enough and it just runs it into the ground. We finally decided to pull the plug. In my 40 years I’ve never slept so good. It’s like hotel good but in your own bed!!! Install was super easy because I watched him do it, LOL. I kid. I’ll ask for his install input and update but seriously he installed all 4 (3 bedrooms and 1 living room) in 2 days. Probably wouldn’t have taken so long if he didn’t have to pour a pad for them but it was well worth it! Last pic is from the Nest. They were installed Friday. Compare usage from Sat & Sun to before we got them! Insane!!!

I love it
This was best investment I've ever made. I put this on the wall on my porch that I've converted to a sun room. This extra space that I enclosed with plexiglass and wood and sealed with insulation stayed about 20 degrees different from out side. With a window unit and heaters. Now with the split unit it stays what ever temp I want it to be. The della split unit is so quite I have to put my ear on it to hear it run sometimes the out side unit is even quite. If you mount on outside wall that is a little thin and only a few inches thick it might give a little bit of a hum but so slight you have to want to hear it. Turbo cool or heat will cool or heat super fast. The system is perfect 👌 👍 🥰. I love it.

WORKS GREAT IN THE FLORIDA HEAT!!
I live in Florida and our summers are brutal. I installed this in my garage.
It wasn’t a hard install but it took my dad and I about 8 hours. He ran the electrical.
Around this time of the year, my garage is around 82 degrees and +70% humidity, the air is very wet.
This morning it was 74” and 52% humidity.
The indoor and outdoor units are remarkably quieter compared to our house’s HVAC system.

Just great! Extremely satisfied!
I bought and installed 2 of the della mini splits in the last 8 months, one for my double wide 1800 sqf that I am remodeling little by little, and another for my daughters craftsman home. What an improvement! So silent! So efficient! So easy of operating. For the last 10+ years, we have been using windows AC units and radiant heaters after our central heat and air system broke. The suffering is over. We are saving $100 a month on the power bill and enjoying ourselves inside now. Our Great Pyrenees friends are enjoying the AC's too during the scorching hot summer days. They are pretty easy to install. Follow the instructions on the book and watch some videos on YouTube. On the second install, I made an electrical mistake and purchased the wrong breaker. I am only a landscaper by the way. No problem! I called the technical support number and a very nice tech called me back after just a few hours and figured it out by phone within 5 minutes. It is all great! We just keep it simple by using the remotes. I love the delay timer option. Now that the weather is cooling down (80's max), I set the timer so it doesn't come ON automatically before 12 pm. By the time the girls come from school, 75°f is back as set. GREAT PRODUCT, GREAT TECHNICAL SUPPORT

Installation was a breeze. Unit is working flawlessly. I love that it connected to my Alexa and I can voice control or use the Della app. I am going to purchase a second Della for our guest home.

Good quality, so it is a little heavy for me
Got these panels for my backyard as the wall for the Composting area. Black is good for absorbing the heat of the sun and is easy to hide the ugly things. It is a good quality product. The foot support is stainless steel and long enough to bind the ground and the panels. As it is with a good quality, it is just a little heavy, which may require two people to move around or install it.

Solid and easy. Good product
Solid plastic material. Assembly was easy with a power screwdriver. Looks better than an ugly air conditioner unit.

Nice air conditioner fences
Great value and just the right size. Note that if you want to place them in a straight line, you will need to use an electric screwdriver to tighten the screws.
