D.  Electrical Connections for the Indoor Unit
NOTE:  Be certain all wiring complies with local building 
codes and NEC and that the supply voltage for this 
system is correct.
•   Place the indoor unit on a solid work surface before 
making electrical connections.
•   Both the outer plastic and inner galvanized steel 
cover plates must be removed to make the electrical 
connections for the indoor unit.
•   Raise the front cover to access the screws for 
removing these covers. 
•   Route the 14/4 AWG wiring through the slot in the 
back of the unit and into the front access panel.  
•   Using a wire stripper, remove the insulation and 
separate the 4 wires.
•   Make wiring connections at each terminal according 
to wiring diagram. Take note of the color of the wire 
at each terminal and ensure the wires are connected 
to the outdoor unit accordingly.
•   Ensure each wire is under the screw terminal plate 
and the plate is tightened.
•   Ensure the 14/4 cable is secured under the strain 
relief bracket. 
•   After the terminal block wiring is completed, replace 
both cover plates and lower the front casing.

Step 2 - Installation of the Indoor Unit (Cont.)
E.  Mount Indoor Unit to Mounting Plate
•   Bundle the refrigerant piping, drain piping, and 
wiring with tape and carefully rout the bundle 
through the piping hole.
•   With the top of the indoor unit closer to the wall, 
hang the indoor unit on the upper hooks of the 
mounting plate.  Slide the unit slightly side to side 
to verify proper placement.
•   Rotate the lower portion of the indoor unit to the 
mounting plate, and lower the unit onto the lower 
hooks of the mounting plate. (see illustration)
•   Verify the unit is secured and flush to the wall.
•   Indoor Unit installation is finished at this time.
G.  To Remove the Indoor Unit
•   Slightly raise the entire unit.
•   Pull the lower portion of the unit off the lower 
hooks and pull slightly away from the wall.
•   Lift the upper portion of the unit off the upper 
hooks.

F.  Condensate Drainage Pipe
•   Verify the condensate drain line has a constant 
pitch downward for proper water flow.  There 
should be no kinks or rises in the tubing which 
may cause a trapping effect of the water (see 
illustration).
 Optional: Can use PVC pipe by connecting a 1” ID 
PVC pipe to the drain line coming out of the wall 
and running to desired location.
