Assembly Instructions
CAUTION
!
All power modules rated at 15A 120V 60HZ.
System capacity to be limited to 15A per
circuit.
No more than 12 outlets should be supplied by
one circuit.

1. All parts are lubricated for life.
2. Any service should be conducted by an authorized
service representative.
3. Perform periodic inspections for loose or broken parts.
LAMINATE:To clean the surface, use a damp cloth or
sponge and a mild soap or detergent. Difficult stains such
as coffee or tea can be removed using a mild household
cleaner and baking soda; mixing to achieve a paste
consistency. Use a stiff nylon bristle brush, scrubbing
(approx. 15-20 strokes) the affected area. Do not scrub so
as to mar (damage, scratch) the surface finish. Stubborn
stains that resist any of the above cleaning methods may
require the use of undiluted household bleach or nail polish
remover. Use a cotton ball saturated with bleach or nail
polish remover (acetone); gently rub the stain for up to two
minutes. Rinse thoroughly with warm water and wipe dry
using a soft cloth. This step may be repeated if the stain
appears to be going away and the color of the laminate
has not been affected.
CAUTION:
Prolonged exposure of the laminate and powder coat
surfaces to bleach will cause discoloration. Always rinse
laminate and powder coat surfaces after cleaning! Failure
to rinse after cleaning can cause damage; even if a small
amount of cleaning solution remains on the surface. A dry
residue may be invisible; however, moisture from cups or
drinks can reactivate it, and result in permanently etched
scars or stains over time.
Recommended Household Cleaners:
• Clorox®* • Formula 409® • Dawn® • Fantastik®
• Dow Bathroom Cleaner with Scrubbing Bubbles™
• Favor® • Windex® • Lestoil® • Glass Plus®
• Pledge® • Grease Relief® • Mr. Clean® • TOP JOB®
• Lysol® Brand Disinfectant Basin/Tub/Tile Cleaner
* Prolonged exposure can mar the surface
CAUTION:
Acidic or abrasive cleaners can damage laminate and
powder coat surfaces; do not use them. Drain cleaners
containing lye will permanently damage the laminate
surface. If you spill a drain cleaner, wipe it up immediately
and rinse several times with water. Hair, textile and food
dyes can cause permanent stains. If dye should happen to
spill, wipe it up immediately with dishwashing detergent or
an all-purpose cleaner. Wipe spills away promptly and rinse
several times with water.
CAUTION
!
Assemble units only as described herein. Failure to
do so may result in instability or assembly failure. All
screws, nuts and bolts must be tightened securely
and must be checked periodically after assembly.
Failure to assemble properly, or to secure parts may
result in personal injury.
ROUTINE CARE AND MAINTENANCE
4
Rust removers contain harsh chemicals, which will quickly
cause permanent damage. If a spill occurs, wipe off all
residues immediately, wash thoroughly with soapy water
and rinse several times. Steel wool and other abrasive pads
will damage the laminate and powder coat face. Do not use
them for cleaning and don’t store steel wool pads on your
countertop; the metal can rust and leave stains. Toilet bowl
cleaners contain harsh chemicals that can cause permanent
damage. If spills occur, wipe up immediately, wash surface
with soapy water and rinse several times.
The cleaners listed below can cause damage to the surface
of laminate:
Chemical Ingredient Synonymous Names
Hydrochloric Acid Muriatic Acid
Hydrogen Chloride
Sulfuric Acid Oleic Acid
Oil of Vitriol
Oleum
Hydrofluoric Acid Rust Remover
Phosphoric Acid Rust Remover
Sodium Hydroxide Caustic Soda
Caustic Soda Lye
Lye
Pumice (abrasive)
Remember, sharp objects can damage the surface of
laminate and powder coat surfaces, marring its beauty and
lowering wear and stain resistance. Although the laminate
and powder coat surfaces are somewhat resistant to
scratch and marring, they can be damaged, even under
normal use.
Laminate and powder coat surfaces may need occasional
dusting depending on where it’s used. To keep the surface
beautiful, use a non-oily furniture spray. (Remember to clean
the spray off several times a year to prevent build-up.)
Furniture polish can also help hide fine scratches in the
surface.
UPHOLSTERED FABRIC: Clean with water-based cleaning
agents, foam or pure water-free solvents. Vacuuming or light
brushing is recommended to prevent dust and soil buildup.
For answers to additional questions regarding care or
cleaning please contact Sedia Systems.
