LOCATION
The refrigerated merchandisers have been designed for
use only in air conditioned stores where temperature
and humidity are maintained at or below 75°F and 55%
relative humidity.DO NOT allow air conditioning,
electric fans,ovens,open doors or windows (etc.) to
create air currents around the merchandiser,as this will
impair its correct operation.
Product temperature should always be maintained at a
constant and proper temperature.This means that from
the time the product is received,through storage,
preparation and display,the temperature of the product
must be controlled to maximize life of the product.
UNCRATINGTHE STAND
Place the fixture as close to its permanent position as
possible.Remove the top of the crate.Detach the walls
from each other and remove from the skid.Unbolt the
case from the skid.The fixture can now be lifted off the
crate skid.Lift only at base of stand!
EXTERIOR LOADING
These models have not been structurally designed to
support excessive external loading. Do not walk on
their tops;This could cause serious personal injury
and damage to the fixture.

WASTE OUTLET AND P-TRAP
The waste outlet is located off the center of the case
on one side allowing drip piping to be run lengthwise
under the fixture.
A 1-1/2" P-trap and threaded adapter are supplied with
each fixture.The P-trap must be installed to prevent air
leakage and insect entrance into the fixture.
NOTE: PVC-DWV solvent cement is recommended.
Follow the manufacturer’s instructions.
INSTALLING CONDENSATE DRAIN
Poorly or improperly installed condensate drains can
seriously interfere with the operation of this re-
frigerator,and result in costly maintenance and product
losses.Please follow the recommendations listed below
when installing condensate drains to insure a proper
installation:
1. Neveruse pipeforcondensate drains smaller than
thenominal diameterof the pipe or P-trapsupplied
withthe case.
2. Whenconnecting condensatedrains,theP-trap
mustbeused aspartof the condensate drain to
preventairleakage or insect entrance.Store plumb-
ingsystem floordrains should be at least14" offthe
centerof thecase to allowuse of the P-trappipe
section.Never use twowater seals in series in any
oneline.DoubleP-trapsin series will cause alock
andpreventdraining.
3. Always provide as muchdownhillslope (“fall”) as
possible;1/8"perfootis the preferredminimum.
PVCpipe,whenused,mustbe supported tomain-
tainthe 1/8"pitch and to preventwarping.
4. Avoidlongruns ofcondensate drains.Longruns
make it impossible to providethe“fall” necessary for
gooddrainage.
5. Providea suitableair break betweenthe floodrim of
thefloor drain andoutlet ofcondensate drain. 1"is
ideal.
6. Preventcondensate drains fromfreezing:
a. Donot installcondensate drains in contact with
non-insulatedsuction lines. Suctionlines shouldbe
insulatedwith anonabsorbent insulation material
suchasArmstrong’sArmaflex.
b. Wherecondensate drains arelocated in deadair
spaces(betweenrefrigeratorsorbetweena
refrigeratorand a wall),providemeans to prevent
freezing.Thewater sealshould be insulated to
preventcondensation.
Refrigeration
GELATO/SOFT ICE CREAM
These display cases are designed to hold product at
temperatures that will allow operators to scoop or dip
gelato and soft ice cream into cones,containers or
dishes.The temperatures will fall in the range of plus 4F
to plus 12F depending on amount of sugar and butterfat
in product.The temperature and condition of product
must be checked after being in case the first four hours
of operation.Because of the sensitive condition of these
products,defrost is very critical.The fans do NOT run
during defrost periods.The maximum time is 20
minutes for electric and 10 minutes for hot gas and
Kool Gas.The fans are on a 2 minute delay after defrost
to avoid adding heat to case.
If,because of ambient conditions,the defrost must be
changed,amount of defrosts not time is necessary.i.e.,3
by 20 minutes instead of 2 x 40 minutes.
REFRIGERANTTYPE
The standard refrigerant will be R-404 unless otherwise
specified on the customer order.Check the serial plate
on the case for information.
Piping for more than one case on a condensing unit is
run underground with either common suction and
liquid lines from the machine room or individual suction
and liquid lines joined together in the machine room.

NOTE: The standard coil is piped at 5/8" (suction); however,
the store tie-in may vary depending on the number of
coils and the draw the case has. Depending on the case
setup, the connecting point in the store may be
5/8", 7/8", or 11/8". Refer to the particular case you are
hooking up.
Refrigerant lines should be sized as shown on the
refrigeration legend furnished by the store.
Install P-traps (oil traps) at the base of all suction line
vertical risers.
Pressure drop can rob the system of capacity.To keep the
pressure drop to a minimum,keep refrigerant line run
as short as possible,using the minimum number of
elbows.Where elbows are required,use long radius
elbows only.

PROGRAMMING
The ERC 2 control initially powers up displaying 12:00
AM otherwise it will show the last configured selection
(time or temperature).If a power outage occurs during
normal operation,the control will maintain the correct
time-of-day using a capacitor (batteries are not
required).The time will be maintained for up to 100
hours when the capacitor is fully charged.
To initiate a Manual Defrost,press and hold the MAN
DEF key for 3 seconds.
There are two levels of programming in the ERC 2.The
first level of security will enable the user to set two
parameters:Time-of-day (CLoC) and Setpoint
temperature (SEt).The other level allows access to the
other parameters.
Three buttons are used for the programming:SET,UP
and DOWN

STOCKING
Improper temperature and lighting will cause serious
product loss.Discoloration,dehydration and spoilage
can be controlled with proper use of the equipment
and handling of product.Product temperature should
always be maintained at a constant and proper tempera-
ture.This means that from the time the product is
received,through storage,preparation and display,the
temperature of the product must be controlled to
maximize life of the product.Hussmann cases were not
designed to“heat up” or“cool down” product—but
rather to maintain an item’s proper temperature for
maximum shelf life.To achieve the protection required
always:
1. Minimizeprocessingtimeto avoid damaging tem-
peraturerise to the product.Productshouldbe at
proper temperature.
2. Keep the airin andaroundthecase areafreeof
foreigngasses andfumes or foodwillrapidlydete-
riorate.
3. Maintainthe display merchandisers temperature
controlsas outlined in therefrigeratorsectionof
thismanual.
4. Donot placeanyproduct intothese refrigerators
untilall controls havebeen adjustedand theyare
operatingat thepropertemperature.Allowmer-
chandiserto operatea minimum of 6 hours before
stockingwith anyproduct.
5. Whenstocking,never allow the producttoextend
beyond the recommended load limit. Air dis-
charge and return air flue must be unob-
structed at all times to provide proper refrig-
eration.
6. Thereare ventslocated at thebase ofthe frontof
theglass,just above thefrontrail.Theseventssupply
acontinuous,gentleflowof airacrossthefront glass
whichinhibits condensation. Do not place any
signs or other restrictive objects on the front
of the refrigerator that will block these vents.
7. Keep the servicedoorsclosed (whenapplicable).
Refrigerationperformance will beseriouslyaffected
ifleft openfora prolonged period oftime.
8. Avoid theuse of supplementalflood orspot lighting.
Displaylight intensity has been designedformaxi-
mumvisibilityand product life atthe factory.Theuse
ofhigher output fluorescentlamps (H.O.andV.H.O.),
willshortenthe shelflifeof theproduct.
9. In the Gelato Pan configuration,all holesmust
befilled (ifonlyan empty pan) to preventairflow
disruption.
CASE CLEANING
Long life and satisfactory performance of any equipment
are dependent upon the care given to it.To insure long
life,proper sanitation and minimum maintenance costs,
the refrigerator should be thoroughly cleaned
frequently. It is essential to establish and regulate
cleaning procedures.This will minimize bacteria causing
discoloration which leads to degraded product
appearance and significantly shortening product shelf
life.
SHUT OFF FAN DURING CLEANING PROCESS.It
can be unplugged within the case,or shut off case at the
source.The interior bottom may be cleaned with any
domestic soap or detergent based cleaners.
The use of hoses and sage machines to clean the inside
of the cases is recommended and is an excellent way to
clean the coil fins and hard to reach corners of the
interior of the cases.Be sure to observe the warnings
below when cleaning the case.
Sanitizing solutions will not harm the interior bottom,
however,these solutions should always be used accord-
ing to the manufacturer’s directions and should not
containAmmonia.
Soap and hot water are not enough to kill this bacteria. A
sanitizing solution must be included with each cleaning
process to eliminate this bacteria.
1. Allowcasesto cometo room temperature
2. Scrubthoroughly,cleaningallsurfaces,with soap and
hotwater.
3. Rinsewith hotwater,but do notflood.
4. Applythe sanitizing solutionaccordingtothe
manufacturer’sdirections.
5. Rinsethoroughly.
6. Drycompletelybeforeresuming operation

CLEANING
PRECAUTIONS
WHEN CLEANING:
Never Use a Cleaning or Sanitizing
Solution that has an OIL BASE
(these will dissolve the butyl
sealants) or AMMONIA BASE (this
will corrode the copper components
of the case)
TO PRESERVE THE ATTRACTIVE FINISH:
Do Use Water and a Mild Detergent for
the Exterior Only!
Do Not Use Abrasives or Steel Wool
Scouring Pads (these will mar the finish)
CLEANING GLASS & MIRRORS
Only use a soft cloth and mild glass cleaner for cleaning
any glass or mirrored components.Be sure to rinse
and/or dry completely.
Never use hot water on cold glass surfaces! It
may shatter and cause serious injury! Allow glass
surfaces to warm first.
NON-GLARE GLASS CLEANING
The high optical clarity of this glass is possible due to
special coatings on the glass surface itself.To preserve
this coating and the optical clarity,keep the glass clean.
Windex®or Glass Plus®are the only solutions recom-
mended to be used to clean the non-glare glass. The
damage to the glass from improper,caustic solutions is
User Information,Cont’d
irreparable.
In addition to cleaning the glass with the recommended
product,there are precautions that should be taken
when working and cleaning the inside of the case.
•Whencleaning theinside of the cases,werecom-
mendthat theglass be fullyopened and coveredto
preventsolutions fromsplashing onto the glass and
ruiningthe coatingon the inside.
PLEXIGLASS & ACRYLIC CARE
Improper cleaning not only accelerates the cleaning
cycle but also degrades the quality of this surface.
Normal daily buffing motions can generated 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.
CLEANING
Hussmann recommends using a clean damp chamois,or
a paper towel marked 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 antistatic and anti-fog capabilities.This product
also seals pores and provides a protective coating.
