CLEANING STEEL SURFACES

(available only with stainless steel models)
Use non-abrasive cleaning materials, and
always polish with grain of the steel . Use warm
water or add a mild detergent to the water and
apply with a cloth . Always wipe rails dry after
wetting .
Use alkaline chlorinated or non-chlorine
containing cleaners such as window cleaners
and mild detergents . Do not use cleaners
containing salts as this may cause pitting and
rusting of the steel finish . Do not use bleach .
DO NOT FLOOD!
Use only enough water necessary to clean
surface. Water must not drip down the case!
Never use ammonia based cleansers, abrasive
cleansers, or scouring pads.

Shut Fans Off during cleaning process.
Do NOT use HOT water on cold glass surfaces.
This can cause the glass to shatter and could
result in personal injury. Allow glass surface
to warm before applying hot water.

CLEANING CONDENSER COILS

Condenser coils should be cleaned at least once
per month . Additional cleaning may be needed
depending on the operational environment .
A dirty condenser blocks normal airflow
through the coils .
Airflow blockage increases energy consumption
and reduces the merchandiser's ability to
maintain operating temperature .
To clean the coils, use a vacuum cleaner with
a wand attachment and a soft (non-metallic)
brush to remove dirt and debris . Do not bend
coil fins . Always wear gloves and protective
eye wear when cleaning near sharp coil fins
and dust particles .
