If it has not yet been removed, remove indoor section front panel by removing the Phillips head screws located at the bottom of the air outlet. It may be necessary to rotate the louvers to locate the mounting screws.

Make piping connections:

NOTE: Right rear piping connections are the preferred configuration.

RIGHT REAR AND BOTTOM PIPING CONNECTIONS

1.Carefully separate the tubing and condensate drain tube from the shipping brackets.

2.Be careful not to bend or kink the tubing. Gently rotate the tubing 90 degrees.

3.Carefully p°siti°n the ind°°r secti°n °nt° the wail bracket" Be sure the tubing and drain tube are routed through the piping hole in the wall.

4.Check that the indoor section is mounted level to ensure proper condensate drainage and to avoid possible water damage. Be sure the drain tube is sloped toward the out- side and is not kinked or bent. Ensure that any drain ex- tension is made outside the wall.

IMPORTANT: All refrigerant lines must be insulated because the refrigerant flow device is located in the outdoor section.

Run liquid and suction refrigerant piping.

1.Run pipes as directly as possible, avoiding any armec- essary turns and bends.

2.Suspend refrigerant pipes s° that the insulati°n is n°t darn"

aged and vibrations are not transmitted to the structure.

3.Leave slack in refrigerant pipe between the structure and the indoor and outdoor sections to absorb vibration.

Step 6 --Make Piping Connections

NOTE: The outdoor section must be connected to the indoor section using field-supplied tubing.

To make connections:

1.Unpack factory-supplied tubing package. Unwind tubing carefully. Do not bend or kink tubing.
