1.  Select and mark the area for the suspension or console bolts (use 
embedded inserts or anchor bolts in new buildings, and hole-in-
anchors in older buildings). 
2.  Drill the holes. 
3.  Add the set-anchor and the plate washer to the bolts (bolts must 
be at least 13/32 inches in diameter), and then insert the bolts 
into the installation area. 
4.  Add the plate washer, spring washer, and nut to secure the bolts 
into the installation area. 
5.  Position the indoor unit installation plates onto the bolts. Secure 
using nuts, plate washers, and spring washers. Adjust for level as 
necessary. 
• Unit must be installed correctly. Tighten the nuts and bolts to prevent the unit from falling and 
causing severe injury or death.

Installing the Drain System
• Drain piping must have downward gradient of at least 1/50 to 1/100; to prevent reverse flow, slope must 
not be straight up and down.
•  Do not damage the drain port on the indoor unit when connecting the field-supplied drain piping.
