Aire acondicionado minisplit DELLA Optima Plus Series 9000 BTU 25 SEER2 Ultra Hyper Heat - Hasta 400 pies cuadrados
Esta unidad utiliza refrigerante R454B. Viene precargada con refrigerante R454B para una línea de hasta 7,5 metros. Si su instalación no supera esta longitud, no se necesita refrigerante adicional.
Sí, puede comprar un conjunto de líneas más largo por separado. Si lo compra junto con el sistema minisplit de zona única, recibirá un 10 % de descuento. Tenga en cuenta que si el conjunto de líneas extendido mide más de 7,6 metros (25 pies), se requerirá refrigerante adicional. Asegúrese de consultar con un técnico profesional de HVAC para una instalación correcta.
En modo automático, la unidad alterna automáticamente entre refrigeración y calefacción para mantener la temperatura establecida. Puede ajustar la temperatura objetivo manualmente, normalmente entre 15 °C y 30 °C, según su comodidad.
El condensador y las líneas del minisplit no están prevacíos. Deberá vaciar el sistema durante la instalación para eliminar el aire y la humedad antes de liberar el refrigerante; esto es esencial para su correcto funcionamiento y larga vida útil. Puede utilizar nuestro servicio de kit de alquiler, que incluye todas las herramientas necesarias para vaciar e instalar su minisplit.
Normalmente, tardamos un día hábil en gestionar el envío. Durante la temporada alta, tardamos de 2 a 4 días hábiles. Ofrecemos envío terrestre gratuito, por lo que no hay cargos adicionales por envío ni manipulación.

I installed the unit in a standard 12x12x12x12x12 pentagon with two floors, 11’ ceilings! The floor, walls and roof are treated with spray foam for an ideal space to cool. I have the unit set to “dry out mode. In 5 1/2 days the unit has removed 11 mop buckets of moisture. The bottom floor (foamed) suffered several heavy rain showers…. I drilled holes in the subfloor to allow the unit to extract that trapped moisture. Overall, I am quite pleased with my Della unit! I would give it a 5, but feel like that would be a chump move. Statesboro Georgia is, in legendary Coach ERK Russel’s words, the gnat capital of the world. Gnats love heat and humidity, so does my Bella Della!

I am truly impressed with these Della split units. This was the perfect choice for the space being used. I ordered everything needed to make for a great installation. Wall bracket (keep it off the ground and keep it clean) line sets (well packaged and protected) line set covers (good product for fair price). The inside units are a nice looking unit and their sizing is common to all others out there. Well done Della! Thank you!

Thai review comes while I'm currently in a heatwave with a heat index of around 110 degrees.
This unit is incredible. Ice cold air, even when it's brutally hot and humid. The up-down/left-right louvers are great.
Indoor unit is attractive. Honestly I feel like my 9k Della has more cooling power than my 12k Mr.cool.
Installed it myself. Everything went well

Very easy DIY install. And so quiet inside and out!

I brought the DELLA mini split mainly because of the rental kit to make the installation much easier. The vacuum pump, torque wrench, and for me the best feature the plastic tubing you put inside the copper tubing to help you from bending the copper tubing.

I ordered the 9000 btu 230v system w/25' lineset. The equipment arrived three days after I ordered it. I also rented the installation kit for the diy install. To purchase the needed equipment would have been between $250-300. I watch the recommended Youtube videos and several others. I installed both the indoor and outdoor units following the video instructions, and the written instructions in the manual, using the rental equipment. At the coldest setting it blows 40 deg air. At the warmest setting it blows 140 deg air. This awesome little system will make my home office much more comfortable to work in during the winter and summer.

It is 20° outside right now and it says it feels like 11 and the room is staying warm. The only issue is the installer had to make a lot of modifications compared to my last unit, but he got it in.

Unit works great. My issue is interior fan runs all the time in AC mode with compressor on or off fan runs constantly. So fan runs 24/7 in Arizona.

This company is absolutely unbelievably incredible. The HVAC technician more than likely cross-threaded the liquid line service valve nut. The nut had to be cut off, which completely destroyed the valve. I contacted DELLA, who requested pictures of the damage. In complete amazement, they did not send a new valve but instead replaced the outside unit, AT NO CHARGE!!! This is after I told them I would pay for all parts and replacement costs. I even emailed them and stated the damage was not due to the manufacturer's defect, and I told them I was not seeking any warranty or compensation. This is a truly great company, and I highly recommend them if you want a mini split and want a company that stands behind its products. I have always wanted to add a mini split to my upstairs rooms, and after this wonderful customer service, it will definitely be a DELLA.

We have 4 now in our home, and my husband installed them himself. They work great! Just like having central air in the summer, & so far keeping rooms warm this winter. Seems good on the electric bill, too!
Best part is you're able to control air & heat for each room.

This is a great unit. worth every penny. Pro install recommended.
Joe N.5/5Verified
Easy install! Wish I had leased the install kit and just returned it to get the longer warranty. I already owned all required equipment, and I did not realize it would affect my length of warranty.

This is my second Della mini-split install and it was a breeze. The order was delivered in just a few days and installation went easily. The first unit (18K) has been running for 2-1/2 years without any issues. It heats and cools quickly, is quiet and quite efficient.
If you are mechanically inclined and can follow instructions, there should be no problem doing an install of one of these units. The only concern I had was in vacuuming the lines, as I don't have experience in that. But, it was pretty straightforward and went without a hitch.
I'd recommend Della to anyone.
Joe B.5/5Verified
Pretty easy install. Make sure to order the line set.
In Louisiana is hot one day and cold the next. I recommend this mini split for anyone who can’t keep a room comfortable. It works like a charm.

This is my third Della Mini Split we have purchased and installed. I am very pleased with the operation of these units. I would give 5 stars, but the order process had a flaw in that it allowed me to order this unit without a line set.
I previously had to purchase a longer line set for the second unit we installed because it came with a 16 foot line set which was not long enough. When I purchased that unit, it automatically came with the 16 foot lines and I did not see an option to change that.
That worked out for me because this time, I was supposed to choose a length for the line set. It was a drop down menu that I did not see. This should have been set up so that if I truly did not want to include the line set, I should have had to choose that as an option. Instead, it let me order with that field blank. If I did not happen to have an extra line set, I would have been unable to finish my install.
A second observation...I installed one of these in my shed, which is intended to be a work shop for my wife also. In normal circumstances, we would only like to heat it to about 45 degrees. The lowest setting on the Della is 61 degrees. I was unaware of that when we purchased it. This may not be important in most installation scenarios, but someone else may have a similar need and it might help you to know that.
Overall, we are pleased with the Della units. Very straightforward installation and we have had zero problems with them. Incredibly quiet inside and outside. You can stand right next to the outside unit and have a normal conversation. Truly impressive. Change the order process Della so someone cannot accidentally order without a line set and it will be a five star experience.
