3. Indoor Unit Installation Installation Location Indoor Unit Adequate Support! Building structure must be adequate to support the weight of the unit. Failure to ensure adequate structural support could result in unit falling from its location which could result in death, serious injury, or equipment or property only damage. 1.Avoid locating the indoor unit where the return and/or supply air may be obstructed. 2.Select a location where it is easy to drain the condensing water and connect to the outdoor unit. 3.Keep the indoor unit far away from heat sources, vapor and flammable gas. 4.Be sure that the installation of the indoor unit conforms to the installation dimension diagram. 5.Be sure to leave enough space to allow access for routine maintenance. 6.Install in a location where the unit is more than 3 feet away from other electric appliances such as television, audio de- vices etc. 7.Select location where air filters can be easily removed.

4. Positioning for mounting console unit Step 1 Indoor Unit Installation Select a wall location suitable for the installation of the indoor unit. (Refer to the installation manual for location and dimension spacings.) Locate building support members sufficient to hold 4 times the weight of the unit being installed. Mark the location for the support brackets and side screws.

5. Positioning for mounting console unit Step 2 Indoor Unit Installation Mount the support brackets. Be sure that the brackets have been fixed firmly enough to withstand 4 times the weight of the unit. If wall anchors are needed for the four side screws, install them at this time.

6. Marking hole location Step 1 Indoor Unit Installation The piping and wiring can exit the console unit in one of six directions. Left side, right side, back left, back right, left down and right down. Knockouts are provided on the left and right sides of the unit for piping exiting either of these positions.

7. Marking hole location Step 2 Indoor Unit Installation Mark the hole position referencing the shown diagrams.

8. Drilling the hole in the wall to install the piping Step 1 Indoor Unit Installation When the piping and wiring exits the console unit at the back of the unit, special attention is required for the angle of the hole drilled. Find the location on the exterior wall where the piping and wiring will exit the building. Drill a 2 ½” diameter hole at a slight downward angle from the inside wall towards the outdoor wall so that the outside hole is a ¼” lower than the hole on the inside.

9. Drilling the hole in the wall to install the piping Step 2 Indoor Unit Installation Insert a sleeve into the hole to prevent the connection piping and wiring from being damaged while being inserted through the hole.

10. Drilling the hole in the wall to install the piping Step 3 Indoor Unit Installation Pass the piping and wires through the hole using caution to ensure tubing, wiring and insulation is not kinked or damaged. Insulate the piping hole both inside and out after the piping connections have been completed at the indoor and outdoor units. Note: Image for illustration purposes only. The entire drain line tubing must be wrapped to prevent moisture from cool condensate coming in contact with and damaging the ceiling or wall.

11. Installing console unit Step 1 Indoor Unit Installation Raise the console unit into position, placing the unit on the brackets. Indicator marks molded into the housing allow for easy alignment of the console unit to the brackets.

12. Installing console unit Step 2 Indoor Unit Installation Slide the front cover locks to the open position and remove the front cover.

13. Installing console unit Step 3 Indoor Unit Installation Remove the screws holding the case front in place. Release the retainer clips on the lower left and right sides of the case and pull the bottom of the case out from the unit. Lift the case up and release the four top clips located along the top edge of the case front. Remove the case front from the console unit.

14. Installing console unit Step 4 Indoor Unit Installation Locate the four side holes on the console unit and install the four screws.

15. Installing the water drain pipe Step 1 Indoor Unit Installation Attach the condensate drain line to the console unit drain line. Insulate the drain line as necessary.

16. Installing the water drain pipe Step 2 Indoor Unit Installation The condensate drain line should have the proper gradient to ensure proper drainage. Make sure the piping does not have any droops or sags in it that may create a trap in the line.

17. Installing the connection pipes Step 1 Indoor Unit Installation A flaring kit may be necessary for the installation of the lineset.

18. Installing the connection pipes Indoor Unit Installation Align the center of the piping flare with the relevant fitting. Screw in the flare nuts by hand and then tighten the nuts with a spanner and torque wrench. Refer to the chart for proper torque. Note: First connect the connection pipe to the indoor unit and then to the outdoor unit. Pay attention to the pipe bending. Be sure to not damage the connection pipe. To avoid leakage be sure not to over-tighten the joint nut. Note: Refrigerant lines should be separately insulated. Once the piping has been connected to the outdoor unit and a leak test has been performed, slide the insulation over the joints to completely insulate the connections.

19. Installing the indoor unit wiring Step 1 Indoor Unit Installation Remove the cover plate, revealing the main PC board and terminal block.

20. Installing the indoor unit wiring Step 2 Indoor Unit Installation Firmly attach the power connection cables to the terminal block in the indoor unit, making certain to observe the proper terminal connections as shown on the unit wiring diagram. Note: In addition to the outdoor breaker/fuse disconnect, a breaker or fuse is required for each indoor unit. The installation must be done in accordance with National, State, and/or local codes.

21. Installing the indoor unit wiring Step 3 Indoor Unit Installation The electric wire must be tightened securely with the wire restraining clip.

22. Installing the indoor unit wiring Step 4 Indoor Unit Installation Reattach the cover plate to the electric box.

23. Reassembling the console unit Step 1 Indoor Unit Installation Replace the case front onto the console unit, making sure all clips re-engage.

24. Reassembling the console unit Step 2 Indoor Unit Installation Reinstall the screws removed during disassembly.

25. Reassembling the console unit Step 3 Indoor Unit Installation Reinstall the front cover and slide the latches to the lock position.
