The Air Screen Refrigerator was designed to operate at a
range of 36 F (2.22 C) to 40 F (4.44 C). The pull down time
(time required to go from room temperature to 36 F) is
approximately 40 minutes.
The Air Screen Re f ri g e rator ope rates basically the same as
other re f ri g e rated ca rt s, except it maximizes air flow thro u g h
s pecial duct s. The Ra n co therm o s t at mo nitors the ca rt te m-
pe rat u re and turns the condensing unit on when be l ow
s e t p o i n t te m pe rat u r e. The condensing unit then co n d e n s e s
the re f r i g e ra nt to cre a te the cold air, which is cycled thro u g h
the eva po rator located in the top housing. The two ce nte r
f a n s , which are always on, then circ u l a te air through the
eva po rator cold coils and into the ca rt . When the ca rt re a c h e s
the set te m pe rat u re the therm o s t at turns the co n d e n s i n g
unit off. Mo i s t u re is re m oved from the air when the co n-
d e n s ate unit is energ i ze d. When this oc c u r s , the moisture
will drip into the pan located be n e ath the eva po rato r. Th e
m o i s t u r e then drains down to the co n d e n s ate eva po rato r,
which boils the water away. When the ca rt door is ope n e d,
the two outer fans turn on and increase the air flow. Th i s
i n c r eased airf l ow through the ducts cause a screen of air
a c r oss the ca r t holding the cold air inside.
IMPORTANT:
To maintain proper temperatures in the air curtain and
to prolong the life of the co m p r e s s o r, the condenser co i l s
must be cleaned on a regular basis. It is recommended
that the coils be checked and cleaned on a m o nt h l y.
This proce d u re is not cove r ed under wa r ra nty, however
is to be performed only by qualified engineering/main-
tenance personal.
Cleaning procedure:
• Tu rn unit off and unplug from elect ri cal power source.
• To access the co i l s , re m o ve the louve red panels locate d
at the bottom of the unit.
• Use a vacuum cleaner with a brush at t a c h m e nt to clean
the co i l s . In ext reme cases of dust and grease buildup,
co m p ressed air may be re q u i red for cleaning the co i l
f i n s . Use caution when doing this.The air curtain must
be moved to an isolated location to pe r fo rm this proce -
d u re. O n ce the coils have been cleaned, i n s p e ct for be nt
coil fins. St ra i g h ten be nt fins using a stra i g h tening too l
called a co m b.
• The co m p ressor motor and other co m p o n e n ts can be
cleaned using stiff brush or whisk broo m .
CAUTION: Do not use steel wool pads as they will result in
rusting from the ferrous metal in the pads.

2. Vinyl trim should be washed with a chlorine-free deter-
gent and water. Rinse thoroughly with clear water and
allow to dry. Never use abrasive cleaners, waxes, car pol-
ish, or substances containing strong aromatic solvents or
alcohol. Use of direct steam/hot water cleaning at tem-
peratures above 190° F may result in “bubbling”or loos-
ening or vinyl adhesive.
3. To clean stainless steel surfaces use only cleansers,
detergents, degreasers, or sanitizers that are certified to
be “chloride-free”and “phosphate-free,” and cleansers,
degreasers, or sanitizers only in the recommended
concentrations. DO NOT exceed recommended concen-
trations or mixing ratios. After cleaning and sanitizing,
rinse all ex p osed surf a c es thoroughly with large amount s
of clear water.Wipe off any standing liquid or residue
from all horizontal surfaces in corners, or near edges.
