This Booklet specifi cally covers the
Following models:
Entyce TY3
TY4
Descrip on: The ENTYCE-HOT/COLD model series are Mul -deck island merchandisers designed for medium
temperature applica ons such as: Deli/Dairy/Beverage. The case is a combina on of a remote type models,
which require separate condensing unit connec ons as well as a self-contained model. Each self-contained
model will have it’s own condensing unit, factory installed beneath the display area of the case ready for
opera on when electrical service is connected.
Shipping Damage: All equipment should be thoroughly examined for shipping damage before and during
unloading. This equipment has been carefully inspected at our factory and the carrier has assumed
responsibility for safe arrival. If damaged, either apparent or concealed, claim must be made to the carrier.
Apparent Loss or Damage: If there is an obvious loss or damage, it must be noted on the freight bill or express
receipt and signed by the carrier’s agent; otherwise, carrier may refuse claim. The carrier will supply necessary
claim forms.
Concealed Loss or Damage: When loss or damage is not apparent un l a er all equipment is uncrated, a claim
for concealed damage is made. Make request in wri ng to carrier for inspec on within 15 days, and retain all
packaging. The carrier will supply inspec on report and required claim forms.
Loca on/Store Condi ons: The refrigerated merchandisers have been designed for use only in air condi oned
stores where temperature and humidity are maintained either75°F ambient and 55% RH. DO NOT allow
air condi oning, electric fans, ovens, open doors or windows (etc.) to create air currents around the
merchandiser, as this will impair its correct opera on.
Shortages: Check your shipment for any possible shortages of material. If a shortage should exist and is found
to be the responsibility of Hussmann Chino, no fy Hussmann Chino. If such a shortage involves the carrier,
no fy the carrier immediately, and request an inspec on. Hussmann Chino will acknowledge shortages within

TY3 4X4E-S Cold Section

Cold Sec on Start up
1. Apply power to the merchandiser.
2. Wait for the self check to complete.
•During the self check, each LED fl ashes for one second, then
all LEDs turn on for two seconds.
•If the LEDs do not fl ash, make sure the adjustment knob is
not in the Off posi on.
3. The compressor will start for 30 seconds a er the self check
is complete.
• The merchandiser temperature displays at startup
•An ini al defrost occurs two hours a er startup
•The compressor runs un l it reaches its setpoint tempera-
ture un l defrost.
4. Refrigera on: The compressor will con nue to cycle on-and-
off normal un l defrost occurs.
5. Defrost: Defrost is scheduled to occur every 8 hours, or ear-
lier if triggered by a demand defrost.
•Defrost con nues for a set  me period, or un l the defrost
termina on temperature is reached.
•During defrost the display shows the ini al defrost tem-
perature (temperature at start of defrost)
•This ini al defrost temperature is displayed for the set  me
period (even if refrigera on mode resumes before the end
of this period).
6. If power is interrupted, the process will start over at step 1.
Opera on
1. DO NOT LOAD PRODUCT un l case reaches desired opera ng
temperature (approx. 4 hrs).
2. Food Product temperature must be below 38°F when loading
a case. Case is not designed to chill food.
3. Check shelf loading. Overstock will reduce case performance
and opera on.
4. DO NOT block discharge or return air. DO NOT display pack-
ages over the air inlet located at the front of the lowest deck.
This restricts airfl ow, and will result in warmer temperature in
the case.
5. DO NOT display more than 150 pounds of product per shelf.
Addi onal weight will damage the shelves.

Do Not Install the Vented Panels of the
self-contained model against a wall or
other storage fi xture.
Located in the lower front and rear of the self-contained
models are vented panels. These panels allow air circulation
to the condensing unit. Blocking or restricting air circulation
through these panels can cause poor performance and
damage the refrigeration system.
Exterior Loading
Thesemodelshavenotbeenstructurallydesignedtosupport
excessive external loading. Do not walk on their tops;
This could cause serious personal injury and damage to
the fi xture.
Leveling
A LEVEL CASE IS NECESSARY TO INSURE PROPER
OPERATION AND WATER DRAINAGE.
Note: To avoid removing concrete fl ooring, begin lineup
leveling from the highest point of the store fl oor.
Store Conditions
Uncrating the 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 fi xture can now be lifted off the crate skid. Lift
only at base of stand!
Installation
Condensate Pan Setup
There is one condensate evaporator pan on this unit. The drain pipe from the case feed into the condensate pan, once
water levels are high enough in the condensate pan the fl oat switch level is triggered which will then trigger the heater to
raise temperature therefore evaporating the water into the case airstream.

Field Wiring and Serial Plate Amperage
Field Wiring must be sized for component amperes printed
on the serial plate. Actual ampere draw may be less
than specifi ed. Field wiring from the refrigeration control
panel to the merchandisers is required for refrigeration
thermostats. Case amperes are listed on the wiring
diagram, but always check the serial plate.
CASE MUST BE GROUNDED
NOTE: Refer to label affi xed to case to determine the
actual confi guration as checked in the “TYPE
INSTALLED” boxes.
Standard lighting for all refrigerated models will be full length
LED Lights located within the case at the top.

Case Cleaning
To insure long life, proper sanitation and minimum
maintenance costs, the refrigerator should be thoroughly
cleaned frequently. SHUT OFF FAN BEFORE CLEANING:
It can be unplugged within the case, or shut off entire case
at the source. The interior bottom may be wiped with any
domestic soap or detergent based cleaners. Sanitizing
solutions will not harm the interior bottom,
WARNING! DO NOT USE WATER HOSES! A self
contained case empties into an evaporator pan that WILL
OVERFLOW IF TOO MUCH WATER IS INTRODUCED

Service Tips
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 temperature. This means that from
thetime the productisreceived,through storage, preparation
anddisplay,thetemperatureoftheproductmustbecontrolled
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. Minimize processing time to avoid damaging tem-
perature rise to the product. Product should be at
proper temperature.
2. Keep the air in and around the case area free
of foreign gasses and fumes or food will rapidly
deteriorate.
3. Maintain the display merchandisers temperature
controls as outlined in the refrigerator section of
this manual.
4. Do not place any product into these refrigerators
until all controls have been adjusted and they are
operating at the proper temperature.Allow mer-
chandiser to operate a minimum of three (3) hours
before stocking with any product.
5. When stocking, never allowthe product to extend
beyond the recommended load limit.Air dis-
charge and return air fl ue must be unobstructed at
all times to provide proper refrigeration.
6. Avoid the use of supplemental fl ood or spot light-
ing.Displaylight intensityhas been designedfor
maximum visibility and product life at the factory.
