SPLIT AC INSTALLATION...... ||FLIER OUTSIDE THE ROOM || Jabirwaqas.com

A mini-split system has two main components: an indoor evaporator, which cools the air, and an outdoor condenser, which dissipates heat. They’re connected by a line set, tubing that passes through a baseball-size hole in the wall, carrying hot refrigerant outside and cold refrigerant in. Our line set also included cable to power the evaporator and a drain line to carry condensation outside. Mount the evaporator inside the room on an exterior wall away from direct sunlight, doorways and sources of dust. Make sure this area of the wall is free of wires, pipes and ducts that would interfere with making a hole for the line set. Mark the stud locations and fasten the bracket to them with screws. The line set hole must slope slightly downward to the outside so condensate from the evaporator can drain outside. Begin by drilling a pilot hole from inside to outside. Then go outside and make sure no trim or other obstructions will complicate drilling the full-size hole. Cut with a hole saw from inside, move aside any insulation and inspect the wall cavity for obstructions. Finish the hole by drilling from the outside. Carefully uncoil the line set from the back of the evaporator. With an assistant outside, feed the line set through the hole. As it emerges, the assistant should gently bend the line set downward and to the side as needed to reach the condenser. Keep the rigid plastic collar surrounding the line set at the end that connects to the condenser. The drain line is shorter and goes through last, below the other lines. Add the drain extension and wrap the joint with electrical tape to keep it secure. Wrap the foam sleeve around the section of line set within the hole and replace any insulation in the wall cavity that was disturbed. Then hang the evaporator on the mounting bracket. Pro tip: Your helper may need to feed a few more inches of the line set outside as you do this. On the outside, insert the two-piece plastic trim into the hole to prevent any rough edges from damaging the line set. Set the condenser on a pad on the ground or mount it on a wall bracket so that the refrigerant lines can reach it easily. Route the line set so it stays tight to the building exterior and doesn’t leapfrog any obstructions. This makes it easier to install a cover. Ensure the condenser has the recommended clearance from walls and bushes. Avoid placement where ice or packed snow could fall on it or where other appliances vent. A location on the east or north side of the structure maximizes cooling efficiency.\ This step varies by manufacturer. With this system, a locking lever presses the line connections together. Before powering up, inspect the refrigerant lines for kinks and verify the electrical connections. Then go inside and set the temperature using the handheld controller. Insulate and seal the hole in the outside wall, then cover the line set using sections of plastic or metal channel cut to length. Place the back half of the channel behind the line set, plumb it and anchor it to the wall with self-tapping screws. Our line set travels horizontally to the compressor, so when we added the channel corner, we drilled a hole in it to allow the drain line to exit straight down. Jabirwaqas.com
