OVERVIEW / NSF® TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS - PAGE 1 of 2
OVERVIEW
These Structural Concepts Oasis® self-service
cases are designed to merchandise packaged
products at 41 °F (5 °C) or less product temperatures
(unless custom cases with wire rack shelving).
Cases should be installed and operated according to
this operating manual’s instructions to insure proper
performance. Improper use will void warranty.
TYPE I vs. TYPE II ENVIRONMENTAL CONDITIONS
This unit is designed for the display of products in
ambient store conditions where temperature and
humidity are maintained within a specific range.
Type I display refrigerators are intended for use in an
area where environmental conditions are controlled
and maintained so that the ambient temperature does
not exceed 75 °F (24 °C) and 55% maximum humidity.
Type II display refrigerators are intended for use in an
area where environmental conditions are controlled
This equipment MUST be installed in compliance with
all applicable NEC, federal, state and local
ATTENTION
CONTRACTORS
and maintained so that the ambient temperature does not
exceed 80 °F (27 °C) and 60% maximum humidity.
If unsure if your unit is Type I or II, see tag next to serial
label. See SERIAL LABEL LOCATION &
INFORMATION LISTED / TECH INFO & SERVICE
section in this manual for sample serial labels.
COMPLIANCE
Performance issues when in violation of applicable
NEC, federal, state and local electrical and plumbing
codes are not covered by warranty.
See below compliance guideline.

OVERVIEW / NSF® TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS - 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, TYPE I AND TYP II ENVIRONMENTAL CONDITIONS,
COMPLIANCE and WARNINGS.
CAUTION
CAUTION
Fluorescent lamps have been treated to resist breakage
and must be replaced with similarly treated lamps.
CAUTION
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.
CAUTION! ADVERSE CONDITIONS / SPACING ISSUES
Performance issues caused by adverse conditions are NOT covered
by warranty.
End panels must be kept at least 6-inches away from any structure to
prevent condensation.
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.).
Tile floors, low ceilings or small rooms will increase noise level.
Whisper Cool compressor blanket or remote unit may resolve noise
level issues.
Keep at least 8-inch clearance above unit for air discharge
(self-contained units only).
WIRING DIAGRAM FORMAT & LOCATION
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.

INSTALLERS: FOLLOW THESE INSRUCTIONS
1. Remove Shipping Brackets Attached to Skid
Remove screws holding Case Shipping Brackets to skid.
Remove Case Shipping Brackets from Skid.
See illustration at right. Note: Shipping Brackets will vary
in size, shape, material and location depending upon case
type and model.
2. Remove Unit From Skid
While supporting case, carefully slide case off from skid at
either left or right side of case (NOT at case rear or front).
See illustration at mid-right for method.
Remove Shipping Support Board
Place into proper position.
3. Attach Condensate Pan to Unit
Condensate pump pan is shipped separately from case.
After case is in position, plug cord into electrical box at
underside of case, hook condensate hose to pump nozzle.
Slide into place (at case underside).
See illustrations 3A through 3D below.
Note: Images 3A through 3D are for illustrative purposes
only. Though images may show condensate pan on skid,
case has been removed from skid prior to these steps.
Caution! Be sure to loop the pump’s electrical cord
through the cord hooks under the case.

POSITIONING CASE / SHIMMING SUPPORT RAILS / ADJUSTING LEVELERS
Note: Units shown may not depict an exact representation of your particular unit being installed.
1. Position & Align Case Alongside Other
Cases
Before adjusting levelers (or shimming frame
support rails), make certain that the case is
in proper position and, if required, aligned
with adjoining case(s).
This may require the repositioning of the
case you are installing or
the already
positioned case(s).
2. Cases With Frame Support Rails: Shim
Illustration at top right shows case with frame
support rails.
Shims will be provided with all cases that
have frame support rails.
Use shims to level case.
Note: After case is in position, it must be
sealed to floor to prevent entry or
leakage of liquid or moisture.
3. Cases With Levelers: Adjust Levelers
After case is in position, adjust case so it is

level and plumb (as shown at right).
You may need to remove front and/or rear
toe-kick to access levelers.
Use adjustable wrench (and possibly a pry
bar) to adjust leveler.
Do not use pry bar on toe-kick as it may
buckle.
Do not use pry bar on end panel; it may chip.
Use pry bar ONLY on base frame to avoid
