Unit Leveling; Assembling Sections - Daikin Vision Installation And Maintenance Manual

Unit Leveling

Place the equipment on a flat and level surface. Where the
surface irregularities could cause the equipment to distort, use
a shim so the base of the unit follows a straight line. Uneven or
distorted sections cause misfit or binding of the doors, panels,
and improper draining of drain pans.
Units over 108" wide must rest on a flat surface for the entire
width of the base rails, or must be shimmed at one or more
points along the length of the rails to prevent distortion or
sagging of the support rails

Assembling Sections

Extended size units ship as separate shipping sections for field
assembly. Shipping sections are provided with a connection
splice joint attached to the cabinet which seals against the
gasket of the frame channel on the adjoining shipping section.
The splice joint provides an air seal between two sections once
they are assembled together. Some unit configurations require
multiple splice joints on the same face or on opposing faces of
a single section. Confirm correct placement and orientation of
unit sections and splice joints based on included unit drawings.
Align all splice joints to seat into the mating gasket to provide
an air seal. Note: Some sections are shipped with shipping
braces.These need to be removed before connecting the
shipping sections. (Figure 5)

Horizontal Airflow Section Mounting
1. Rig the section into position and line shipping sections up
in the direction of airflow. Each section is clearly marked
as to the order of assembly.
2. As the sections are set in place, the holding pins must be
removed from the retractable/removable lifting brackets.
Once the pins are removed, the retractable lifting
brackets can be easily tucked into the base rail and/or
the removable lifting brackets can be removed, allowing
the mating section to seat firmly against the adjoining
section.
3. Pull sections together to fasten. Use a furniture clamp (or
straps) and a ratchet to help pull the sections together
securely at the top and bottom.
4. The unit has a factory-installed base rail. Fasten the
base rails together using the 3/8"-16 × 5" bolts located in
the splice kit provided with the unit.
a. To fasten two shipping sections together, four bolts
are needed (two on each side of the unit). The
bolts run from one base rail into the other and are
fastened with a nut. Complete each bottom/top
section before attaching additional sections.
5. Once the sections are positioned together, additional
section-to-section straps must be secured.
a. Remove the flat head Torx 30 fastener located in
each of the top channel corners (on the mating
edges in the channel piece).
b. Mount the joining strap (shorter strap found in the
splice kit, see
in the channels and refasten the flat head Torx 30
fasteners through the joining plate.
6. Locate and remove the panel screws on each side of
the air handler top panel, as close to the center of each
panel (of each half) as possible. Secure the mounting
straps (longer strap found in the splice kit) as shown in
Figure 8.
