Prima Installation Instructions
(Note: See Exploded Assembly [Figures 4 & 5] and Floor Mounting Details [Figure 6] on following pages.)
1. Use approved floor plan to establish hole locations for the foot plates. (Note that the front hole in each leg panel
floor bracket is located 2-1/2” in front of the chair radius line. Floor bracket holes are offset 1-1/2” from panel
centerline.) Accurate center-to-center width spacing is critical to a proper installation. Tolerance on the chair
width dimension is plus or minus 1/8". It is critical not to exceed this tolerance on width spacing.
2. When mounting chairs over carpet, punch four 5/8" diameter holes in carpet to match holes in the leg panel floor
brackets. (See figure 6.) To attach angle to plinth, use 1/4-20 x 5/8” pan head machine screw with a 1/4” lock
washer. Hand-tighten screws to allow for some slight movement in the leg panel. Bolt panels to floor as per the
appropriate anchoring method.
3. Attach outer back as follows: Fasten both angle back brackets (A) to inside surface of outer back panel (B),
hand-tightening 1/4-20 hex head bolts with star washers at approximate center of slot. Use 1/4-20 flat head
screws (6) with countersink star washers (6) to attach outer back (B) to leg panel (C). Center the back between
leg panels before final tightening. (See figures 4 & 5.)
4. To attach shoulder panel: Fasten upholstered shoulder panel (D) to inner surface of outer back panel (B) by
engaging flush mounts. Center the shoulder panel and fasten to outer back (B) using #8 x 1/2” pan head screw
(2) through exposed hole in strap (2 straps per shoulder panel).
5. To attach lumbar panel: Secure upholstered lumbar panel (E) to outer back panel (B) by pushing upwards into
the base of the shoulder panel (D). The foam at the base of the shoulder panel will compress, forcing the lumbar
panel to drop into place over lower set of flush mounts. When connection is made at flush mounts, center the
lumbar panel (E) and secure to outer back (B) using #8 x 1/2” pan head screw (2) through exposed hole in strap
(2 straps per lumbar panel).
6. Fasten hinge assembly: Align hinge assembly (F) in hinge pocket and hand-tighten 1/4–20 x 1” flat head
machine screws and star washers. Engage thread of each screw before final tightening.
7. Attach seat: Orient the seat to the approximate occupied position and lower onto seat hinges (F). Upholstered
pocket conceals top of seat bracket, but will flex to allow installer to access hinge. Install four (4) 1/4-20 x 5/8”
machine screws with lock washers through slots in seat brackets and fasten to hinges. Insure seat is centered
between panels prior to final tightening.
8. Tighten all floor attachments securely.
