Does this system come with all items needed to install or is that separate?

Thank you for your question. This MRCOOL Olympus mini split system comes with some of the needed accessories, but others will still be required. For a complete installation, you will need a line set for each air handler to connect them to the outdoor condenser. For the outdoor condenser, you will need a disconnect switch and and electrical whip. Depending on your installation you may need a condensate pump for your drain line. The condensate drain line connects to the back of the air handler to remove condensation. For most installations, this drain line runs downward, allowing gravity to carry the condensation away. However, some installations require this drain line to run against gravity. In these cases you will require a condensate pump. We would also recommend a wall mount bracket or equipment pad for the condenser and line set cover guards to both protect and camouflage the line sets. These mentioned accessories can be found on this product page under the "add to cart button". For more assistance, please give us a call.
