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.
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.

DUCT (LOW STATIC) INDOOR UNITS
Duct (Low Static) Indoor Units can be installed in two ways:
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.
