OVERVIEW
These Structural Concepts® Oasis Self-Service
Refrigerated cases are designed to merchandise
packaged bakery products at between 33 °F [1 °C]
and 38 °F [4 °C] / product temperatures.
This case should be installed and operated according
to this Installation and Operating Manual to ensure
proper performance.
Improper use will void warranty.
NSF® TYPE
This unit is designed for the display of products in ambient
store conditions where temperatures and humidity are
maintained within a specific range.
For NSF® Type 1 Conditions (most cases): ambient
conditions are to be at 55% maximum humidity and
maximum temperatures of 75 °F [24 °C].
For NSF® Type 2 Conditions: ambient conditions are
to be at 60% maximum humidity and maximum
temperatures of 80 °F [27 °C].
This equipment MUST be installed in compliance with
all applicable NEC, federal, state and local
electrical and plumbing codes.
If unsure if unit is NSF® Type 1 or 2, see tag next to
serial label. See SERIAL LABEL LOCATION &
INFORMATION LISTED / TECH INFO & SERVICE
section in this manual for sample serial labels.
COMPLIANCE

OVERVIEW / NSF® TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING - PAGE 2 of 2
PRECAUTIONS
Following are important precautions to prevent
damage to unit or merchandise.
Please read carefully!
See previous page for specifics on OVERVIEW, NSF
TYPE, COMPLIANCE and WARNINGS.
CAUTION! LAMP REPLACEMENT GUIDELINES
LED lamps reflect specific size, shape and overall design.
CAUTION
Any replacements must meet factory specifications.
Fluorescent lamps have been treated to resist breakage and
must be replaced with similarly treated lamps.
CAUTION! GFCI BREAKER USE REQUIREMENT
If N.E.C. (National Electric Code) or your local code
requires GFCI (Ground Fault Circuit Interrupter) protection,
you MUST use a GFCI breaker in lieu of a GFCI receptacle.
WIRING DIAGRAM
Each case has its own wiring diagram folded and in
its own packet.
Wiring diagram placement may vary; it may be
placed near ballast box, field wiring box, raceway
cover, or other related location.
CAUTION
CAUTION! POWER CORD AND PLUG MAINTENANCE
Risk of electric shock. If cord or plug becomes damaged,
replace only with cord and plug of same type.
CAUTION! ADVERSE CONDITIONS / SPACING ISSUES
Performance issues caused by adverse conditions are NOT covered
by warranty.
Seismic bracket MUST be properly attached to structure. See SEISMIC
BRACKET RETROFIT INSTRUCTION SHEET for installation specifics.
Unit must be kept at least 15-feet from exterior doors, overhead HVAC
vents or any air curtain disruption to maintain proper temperatures.
Unit must not be exposed to direct sunlight or any heat source (ovens,
fryers, etc.).
Keep at least 8-inch clearance above unit for air discharge.
CAUTION! CHECK BOTH CONDENSATE PAN AND OVERFLOW PAN
Water on floor can cause extensive damage! Before powering up unit:
Condensate pan MUST BE positioned directly under condensate drain.
Overflow pan MUST HAVE single plug connected to its box. Units with
optional Clean Sweep™ MUST HAVE two plugs connected.

INSTALLATION: SKID REMOVAL / PLACING ON SIDE FOR FITTING THROUGH DOORWAYS
1. Remove Case From Skid (Rails)
Remove shipping brace that may be securing case to skid.
Support case to prevent tipping.
Caution! Rails can be damaged if case hits floor with heavy force!
Carefully slide unit to rear of skid and tip backward off skid.
2. Placing Case on its Side for Fitting Through Doorways
Due to case height, unit may need to be laid on its side to transport into store.
Before laying case on its side, remove shelving, product stops, deck pans, etc.
[any pieces or parts that may shift or fall].
Caution Note 1

Caution Note 3
ONLY on its RIGHT SIDE [as shown below] during transport into store.
See below illustration for view of case on its side ready for transport.
After case has been moved to general location, use extreme caution to lift
case upright. Several people will be required to safely perform this task.
After case is upright, parts (shelving, product stops, deck pans, etc.) may be
placed in case.

INSTALLATION, CONT’D.: REAR PANEL REMOVAL / SHIMMING / SEALING
Caution! Risk of electric shock! Only certified
electricians are to access electrical components.
3. Rear Field Access
Note: Access to case rear AFTER installation is
extremely limited (without pulling case out from wall).
To access components at rear of case, remove rear
panel retaining screws (see illustration below). Lift
panel up and off case rear.
While rear panel is removed, (and before moving case
into position), check that evaporator pan is positioned
directly under condensate drain.
Also, before moving case into position, plug cord into
wall (or field wire). See illustration at right.
Caution! To assure proper airflow, replace rear panel
when done.
Slide case into proper merchandising location.
4. Frame Support Rails Must Be Shimmed and
Sealed To Floor
Shims will be provided for all cases that have frame
support rails.
Use shims to level case.
After case is in position and shimmed, it must be
sealed to floor with continuous bead of silicone caulk
to prevent entry or leakage of liquid or moisture.
See below-right illustration of frame support rails.

5. Remove Front Panel / Remove Lower Front Grille
Remove by lifting up and off hooks.
No screw removal is required.
See illustrations at top-right.
Make certain that magnetic air filter is in place (as shown
immediately below and at lower-right).
6. Check That No Shifting or Separation of
Refrigeration Assembly Parts Has Occurred
To check refrigeration assembly, remove the (3) base rail
screws keeping it secure during shipment.
Refrigeration assembly pan rests on plastic glides.
Slide refrigeration assembly out from under case, and
check that no parts have shifted or separated from
assembly.
Also, confirm that wicking material is securely in place
(held securely in upright prongs) as shown below-left.

7. Turn On Power To Case
Caution! Before turning on main power switch, confirm that
no obstructions to fan blades or other moving parts exist.
Lift up deck pans to check for obstructions.
Power cord [located at case rear] should already be plugged
into outlet. See INSTALLATION section of this manual.
If there is no power cord, case is to be field-wired at rear.
See FIELD ACCESS [CASE REAR] section in this manual
for specifics on field wiring.
Access main power switch by removing front grille.
Main power switch is located on main electrical box, below
controller. See illustration at top-right.
8. Confirm Evaporator Coil Fan Discharge
When main power switch is turned on, refrigeration assembly
will energize (see CASE START-UP & REFRIGERATION
ASSEMBLY ACCESS section).
Evaporator coil fans should turn on.
From inside of case, check for discharge air from front baffle
(shown below), to confirm that fans are functioning properly.
Caution! Evaporator fans have protective fan guard to
prevent injury caused by spinning fan blades. Do not
remove fan guard!
Check that cold air is beginning to circulate.
When the case is in a start up mode or has been idle for a
long period of time, a 75 minute run time is required to fully
achieve set point temperatures.

9. Front Panel Bracket Removal
Assembly Note: Front panel bracket is to be
removed and attached to front panel [or wood
cladding] as part of setup.
Brackets with holes (for screws) are provided at
specific locations to attach front panel (or wood

SETUP: OPTIONAL NIGHT AIR CURTAIN OPERATING INSTRUCTIONS
1. Night Air Curtain Operating Instructions
1. Use caution when handling Night Air Curtain.
2. Grasp the handle and pull downward to desired location (see illustration below).
3. Magnets will hold Night Air Curtain in place.
4. To return Night Air Curtain to its retracted position, grasp handle, lift up and away from
its magnetic attachment and carefully wind Night Air Curtain back into roll.
5. Caution!
Do not allow spring-loaded Night Air Curtain to freely snap back into roll.
Doing so can eventually destroy Night Air Curtain’s tension and retractability.
6. To entirely detach Night Air Curtain from case, slide Night Air Curtain toward rear of
case, freeing it from its ‘keyhole’ slots. Lift upward and away from case.
Note: For cleaning instructions, see CLEANING SCHEDULE - TO BE PERFORMED
BY STORE PERSONNEL section in this manual.
