Preparing the Installation Area and Hanging the Indoor Unit Frame
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
should be at least 13/32 inches in diameter), and then insert the
bolts into the installation area.
Figure 134:Preparing the Installation Area.
Install a canvas duct to the air outlet and air inlet so that vibration from the indoor unit does not carry
to the duct or ceiling. Also, add insulation to the interior of the duct, and apply anti-vibration to the
suspension bolts.
• Unit must be installed correctly.
• Tighten the nuts and bolts to prevent the unit from falling.
