IRIS.
A. PRE-I STALLATIO
a. Remove the seat cushion from the chair.
b. Place the chair on a flat work surface or workbench for the
best installation results.
c. Mark or record the hardware placement for the:
• Seat pan location and depth setting (A)
• Back angle setting
• Armrest location (B)(C)
OTE – It is necessary to mark or record the basic fit
characteristics of the chair so that there is an accurate
guide for a correct re-assembly.
B. REMOVE THE SUB-ASSEMBLY
1. Remove the seat pan.
a. Using a 3/16” hex key and a 1/2” open end wrench, remove
the four sets of hardware (A) shown (Fig. 2 and 3).
b. Set the hardware aside for re-assembly later.
2. Remove the armrests (cantilever armrest shown).

socket wrench, remove the hardware (B).

3. Remove the backrest and dynamic sub-assembly.
a. While holding backrest with hands, flex the rockers (E) apart
about 6mm so the backrest assembly may be removed.
OTE – For larger seat widths, removing the Mono backrest
assembly may require 2 people to flex the rockers and
