Notes:
1. Do not use thermostat wire for any connection between indoor and outdoor units.
2. All connections between indoor and outdoor units must be as shown. The connections are sensitive to polarity and will result in a fault code.
INSTALL ALL POWER, INTERCONNECTING
WIRING, AND PIPING TO THE INDOOR UNIT
1. Run the interconnecting piping and wiring from the outdoor
unit to indoor unit.
2. Run the interconnecting cable through the hole in the wall
(outside to inside).
3. Lift the indoor unit into position and route the piping and
drain through the hole in the wall (inside to outside). Fit the
interconnecting wiring into the back side of the indoor unit.
4. Put the upper claw at the back of the indoor unit on the
upper hook of the mounting plate, move the indoor unit
from side to side to see that it is securely hooked.
5. Open the front cover of the indoor unit and remove the field
wiring terminal block cover.
6. Pull the interconnecting wire up from the back of indoor
unit and position in close to the terminal block on the
indoor unit.
7. Push the lower part of the indoor unit up on the wall, then
move the indoor unit from side to side, up and down to
check if it is hooked securely (see Fig. 15).

8. Connect wiring from the outdoor unit per connection
diagram (see Fig. 14 and Fig. 18).
9. Replace the field wiring cover and close the front cover of
the indoor unit.
10. Connect the refrigerant piping and drain line outside of the
indoor unit. Refer to Fig. 12 for the proper installation of
flare connections. Complete the pipe insulation at the flare
connection then fasten the piping and wiring to the wall as
required. Completely seal the hole in the wall.
11. Connect the drain line. The drain line must not have a trap
anywhere in its length, must pitch downwards, and must be
insulated up to the outside wall (see Fig. 16).
