NOTE
The procedure below applies to Sigma-style seats factory equipped with a backrest grab
handle.
For Sigma seats not equipped with a backrest handle, the partition will have to be secured
either by the use of screws or by the addition of handles similar to the factory ones (refer to
part table above for correct part numbers and required quantity).
Both options will require some drilling of the seat backrest at specific positions. Follow the
drilling information’s provided at the end of this procedure to ensure correct installation.

PARTITION CLEANING AND DISINFECTION RECOMMENDATIONS
CLEANING:
First installation
When the partitions are first installed, glazing compound and masking paper adhesive can be easily
removed by applying naphtha (VM &P) or kerosene with a soft cloth, followed immediately with a
thorough soap and water cleaning. DO NOT USE GASOLINE. Adherence to regular and proper cleaning
procedures is recommended to preserve appearance.
Regular Cleaning
Wash the partitions regularly with a mild soap or detergent (dishwashing liquid) and lukewarm water using
a clean sponge or a soft cloth. Rinse well with clean water. Dry thoroughly with a chamois or moist
cellulose sponge to prevent water spots. Do not scrub or use brushes on these products: their coating is
UV-resistant, not mar-resistant. Never dry wipe a dirty surface.
Fresh paint splashes, grease, and smeared glazing compounds can be removed easily before drying by
rubbing lightly with a grade of VM&P Naphtha or isopropyl. Afterward, a warm final wash should be made,
using a mild soap or detergent solution and ending with a thorough rinsing with clean water.
Minimizing Scratches
Scratches and minor abrasions can be minimized by using a mild automobile plastic polish. It is
suggested that a test be made on a sample of polycarbonate sheet with the product selected and that the
manufacturer's instructions be followed.

time 30 seconds.
• HYDROGEN PEROXIDE
Hydrogen peroxide-based spray or wipes with a 3 to 5% concentration – Contact time 2 minutes
minimum.
Not recommended
• BLEACH (sodium hypochlorite)
Regular use of low concentration bleach solution may harm the finish of the partition over time.
Contact of the solution (droplets or over-spray) with the seat fabric may cause discoloration.
In any cases, never expose the partition surfaces to bleach solutions containing more than 10% bleach
concentration.
Do not use
•
AMMONIA
Ammonia (frequently found in glass cleaners) is incompatible with the partition material and will cause
yellowing and/or fading problems as well as surface crazing.
