plexiglass and Acrylic Care

Improper cleaning not only accelerates the cleaning cycle
but also degrades the quality of this surface. Normal daily
buffing motions can generate static cling attracting dust to
the surface. Incorrect cleaning agents or cleaning cloths
can cause micro scratching of the surface, causing the
plastic to haze over time.
BEFORE SERVICING
Always disconnect electrical power at the main
disconnect when servicing or replacing any
electrical component.
This includes (but not limited to) Fans, Heaters,
Thermostats and Lights.

Replacing Fluorescent Lamps

Fluorescent lamps are furnished with a shatterproof
protective coating. The same type of lamp with protective
coating must be used if replaced.
T-5 Bulbs
Please note: T-5 lights must be turned off and on after bulb
replacement.
This lamp has been treated to resist breakage and must be
replaced with a similarly treated lamp in order to maintain
compliance with NSF Standards.
Contact HUSSMAN Chino for replacement.

Cleaning

Hussmann recommends using a clean damp chamois, or a
paper towel marketed as dust and abrasive free with 210
plastic Cleaner and polish available by calling Sumner
Labs at 1-800-542-8656. Hard, rough cloths or paper towels
will scratch the acrylic and should not be used.

Antistatic Coatings

The 210 has proven to be very effective in not only
®
cleaning and polishing the Plexiglass surface, but also
providing anti-static and anti-fog capabilities. This product
also seals pores and provides a protective coating.

Installing perimeter plexiglass

1. If necessary, remove Boston cart bumper
. Loosen screws holding Boston onto case. If a piece
of front plexiglass has to be removed, gently slide it
upwards taking care not to damage foam located on
inside of glass.

connection.
