PREVENTING BLOWER COIL CORROSION

To help prevent corrosion of the blower coil, store all acidic
items, such as pickles and tomatoes, in seal-able containers.
Immediately wipe up all spills.

Exterior Cleaning

,
Never use an acid based cleaning solution on exterior
panels! Many food products have an acidic content,
which can deteriorate the finish. Be sure to clean ALL
food products from stainless steel surfaces.
Clean the area around the unit as often as necessary to
maintain cleanliness and efficient operation.
Wipe exterior surfaces with a damp cloth rinsed in water to
remove dust and dirt from the outside of the unit. Always
rub with the "grain" of the stainless steel to avoid marring
the finish. If a greasy residue persists, use a damp cloth
rinsed in a mild dish soap and water solution. Wipe dry with
a clean, soft cloth.
Never use steel wool or abrasive pads for cleaning. Never use
chlorinated, citrus based or abrasive cleaners.
Stainless steel exterior panels have a clear coating that
is stain resistant and easy to clean. Products containing
abrasives will damage the coating and scratch the panels.
Daily cleaning may be followed by an application of stainless
steel cleaner which will eliminate water spotting and
fingerprints. Early signs of stainless steel breakdown are
small pits and cracks. If this has begun, clean thoroughly and
start to apply stainless steel cleaners in attempt to restore
the steel.
Wipe casters with a damp cloth monthly to prevent
corrosion.

DRAIN

Each unit has a drain located inside the unit that removes
the condensation from the evaporator coil and routes it
to an external condensate evaporator pan. Each drain can
become loose or disconnected during normal use. If you
notice water accumulation on the inside of the unit, be sure
the drain tube is connected to the evaporator drain pan.
If water is collecting underneath the unit, make sure the
end of the drain tube is in the condensate evaporator. The
leveling of the unit is important as the units are designed to
drain properly when level. Be sure all drain lines are free of
obstructions.
