Thank you for your question. This system includes the outdoor condenser and two indoor air handlers with their corresponding remotes. Some additional accessories will be required for a complete installation. For the condenser we would suggest the ductless mini split installation kit for condensers. This kit includes an electrical whip, a non fused disconnect, a surge protector, a CPS charging adapter and a telescoping wall sleeve. We would also recommend a wall mount bracket or equipment pad for the outdoor condenser. For the air handler units, we would suggest the ductless mini split indoor installation kit. This kit includes the refrigerant line set, the control wire and the condensate drain line. You will need one indoor installation kit per air handler, so this system will require two. These kits are available in several different lengths. Depending on you installation you may require a condensate pump. Ideally the condensate drain line uses gravity to carry condensation away from the indoor unit. However, should your installation require the condensate line to run against gravity, you will need a condensate pump. All of these accessories can be found on the product page under accessories, which is located below the add to cart button. For more assistance, please give us a call.
