Installation

1. Choose a location where the indoor unit will be installed. Pick a location that has at least 6″ of clearance from the top of the ceiling and 5″ from each side of the air handler. Make sure the installation location in not in direct sunlight, away from any obstacles that may block air circulation, and at least 3ft away from any other electronic devices.

2. Locate the carboard wall template included with the indoor air handler. Using a level, make sure the template is straight and level before attaching to the wall.

3. Using painters tape, attach the template to the wall the air handler will be installed on.

4. Using the template, mark and drill the holes for the mounting plate to attach to the wall. Also mark and drill the center point for the 3.5 hole to the outside. When drilling through the wall, drill at a slight downward angle to help pass through the lineset, communication wire, and drain tubing bundle.

5. Remove the wall template.

6. Locate the metal wall bracket attached to the backside of the indoor air handler. From the factory, it is attached to the air handler with a sheet metal screw. The screw is located near the center of the air handler. Remove the screw and wall bracket from the air handler.

7. Using the included mounting hardware, install the wall anchors and screw the wall bracket into the predrilled holes in Step 4.

8. Pass the wall sleeve through the wall from inside to outside. From the outside, mark the wall sleeve where it meets the outside wall. Remove the wall sleeve from the inside and cut the sleeve down to size at the location just marked. This will make a flush fit for the wall sleeve and allow for the outdoor beauty cap to be installed on the outside wall.

9. Reinstall the wall sleeve from the inside of the wall opening.

10. On the indoor air handler, locate the refrigerant line and drain tubing connections on the back side of the unit. Carefully bend the connections outward to prepare them to pass through the wall.
    

11. Bundle together the communication cable, refrigerant lineset connections, and drain tubing connection for preparing to pass it through the wall. Wrap the bundle together using the UV tape provided with the air handler. This will protect the bundle and make sure it passes easily through the wall sleeve.
    IMPORTANT – Use two hands when bending out the refrigerant lines, one hand near the base of the connections to brace the factory connections and one hand to bend the lineset. This will prevent the copper from kinking as it is being bent.
    IMPORTANT – Make sure the drain tubing is located at the bottom of the bundle. This will allow for better drainage and ensure no water backs up into the indoor air handler.

12. Prepare to mount the indoor unit to the wall bracket. Carefully pass the bundle through the wall making sure the drain tubing stays to the bottom of the bundle. Place the top section of the air handler on to the bracket first, making sure to catch the clips on the wall bracket to the air handler itself. Once the top clips are in place, press down on the air handler to lock the bottom to the wall bracket.
    
    IMPORTANT – THIS MAY BE DIFFICULT FOR A SINGLE PERSON TO MANAGE. IF YOU HAVE A HELPER AVAILABLE, IT WOULD BE BEST TO HAVE THEM HELP BALANCE OUT THE UNIT AS THE LINE BUNDLE IS BEING PASSED THROUGH THE WALL.

13. From the outside, pass the beauty cover for the wall through the lineset bundle and push into place.

14. Carefully bend the bundle down the outside wall. Use two hands when bending the copper connections like in step 10.
    IMPORTANT – ONE HAND TO BRACE THE COPPER AS CLOSE TO THE OUTSIDE WALL AS POSSIBLE AND ONE HAND TO BEND THE COPPER ITSELF. THIS WILL PREVENT THE COPPER FROM KINKING AS IT IS BEING BENT DOWN THE WALL.

15. Attach the drain tubing extension, provided with the outdoor unit supply bag, to the factory drain tubing connection. Route the drain tubing down the wall to a location where the excess drainage water will not be an issue.
    LINESET CONNECTIONS

16. Locate the refrigerant lineset provided with the outdoor unit. On a flat, level surface, carefully unroll the lineset to prepare and install at the factory connections for the indoor unit just passed through the wall.

17. On the factory piping connections that were passed through the wall, remove the gray and blue caps so you can prepare to install the lineset. On one end of the lineset, also remove the gray and blue caps. Leave the other ends capped that will be connected to the outdoor condenser.

18. Line up the factory connections to the lineset fittings. Hand tighten the first few threads and use the adjustable wrenches to tighten down the rest. Tighten unit all the threads can’t be seen, and the fittings are bottomed out together.
    
    IMPORTANT – BE SURE TO USE TWO WRENCHES WHEN TIGHTENING THE FITTINGS, ONE TO BACK UP THE FACTORY CONNECTION, AND ONE TO SCREW THE LINESET SIDE TOGETHER. THIS WILL PREVENT THE COPPER FROM TWISTING AND BREAKING DURING INSTALLATION.

19. Set the outdoor condenser in place. Pick a location that has no airflow obstructions for the outdoor unit. Make sure no combustible materials will be within proximity of the unit.
    IMPORTANT -MAKES SURE IF THE UNIT 15 BEING MOUNTED TO A WALL BRACKET, IT HAS 6″ OF CLEARANCE FROM THE BACK OF THE UNIT TO THE WALL, 12″ AROUND EACH SIDE, AND 80″ FROM THE FRONT DISCHARGE FAN TO ENSURE PROPER OPERATION. IF MOUNTING THE OUTDOOR TO A UNIT TO A GROUND PAD, MAKE SURE THE SURFACE 15 FLAT AND LEVEL. ON GROUND LEVEL INSTALLS, MAKE SURE THE UNIT HAS 12″ OF CLEARANCE FROM THE BACK OF THE UNIT TO THE WALL, 12″ AROUND EACH SIDE, AND 80″ FROM THE FRONT DISCHARGE FAN TO ENSURE PROPER OPERATION.

20. Remove the Gray and Blue caps on the other end of the refrigerant lineset not installed yet. Also remove the Gray and Blue caps at the connection ports for the outdoor condenser.

21. Repeat Step 18 at the outdoor condenser. Line up the condenser connections to the lineset fittings. Hand tighten the first few threads and use the adjustable wrenches to tighten down the rest. Tighten unit all the threads can’t be seen, and the fittings are bottomed out together.
    IMPORTANT – BE SURE TO USE TWO WRENCHES WHEN TIGHTENING THE FITTINGS, ONE TO BACK UP THE CONDENSER CONNECTION, AND ONE TO SCREW THE LINESET SIDE TOGETHER. THIS WILL PREVENT THE COPPER FROM TWISTING AND BREAKING DURING INSTALLATION.

22. Locate the brass hexagonal valve caps just above the lineset connections. Using an adjustable wrench, remove the valve caps.

23. Insert a 5 mm Allen key into the valve body assemblies. Turn the valve body counterclockwise to open the refrigerant valves. This will release the refrigerant into the system.
    IMPORTANT – YOU WILL NEED TO USE A LITTLE BIT OF FORCE TO OPEN THE VALVE BODIES AND START THE THREADS. ONCE THE VALVE STARTS SPINNING, IT WILL SPIN FREELY. KEEP TURNING THE VALVES COUNTERCLOCKWISE UNIT YOU HIT A GOOD AMOUNT OF RESISTANCE. DO NOT FORCE FURTHER. NOW THE VALVE BODY IS COMPLETELY OPEN. DO NOT CLOSE THE VALVE BODY AFTER THE REFRIGERANT IS RELEASED. IT NEEDS TO STAY OPEN FOR PROPER UNIT OPERATION.

24. Re-install the brass hexagonal valve caps. LEAK CHECKING SYSTEM AND FINAL LINE SET PREPARATIONS

25. Using a spray bottle, prepare a solution of soapy water to leak check the fittings. The more suds in the solution, the easier any leaks will be to find. Dish soap and water works well for this process.

26. Spray down all the refrigerant lineset connections and fittings with the soapy solution.
    Let the excess solution drip off the fittings and wait to see if bubbles start forming at any of the connection points. If you see bubbles, wipe the fittings down with a clean rag or paper towel and repeat the process. If bubbles form again, a leak is present.
    IMPORTANT – IF A LEAK IS FOUND AND PRESENT, THE FITTINGS WILL NEED TO BE RE-TIGHTENED DOWN. AFTER RE-TIGHTENING THE FITTINGS, REPEAT THE LEAK CHECK PROCESS AGAIN UNTIL NO BUBBLES ARE PRESENT.

27. Wipe down all the soapy water solution off the fittings using a clean rag or paper towel.

28. Using the tar tape provided with the indoor air handler, wrap the factory fittings and lineset connections. Press the tar tape into place around the fittings and mold to the shape of the lineset. Cover the tar tape and fittings with the insulation material
    provided with the air handler.

29. Using the UV tape provided with the outdoor condenser, wrap the lineset bundle for where it exists the home down to the outdoor condenser.
