OVERVIEW / NSF® TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING - PAGE 1 of 2

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].

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

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.

WARNINGS

This page contains important warnings to prevent injury or death.

Please read carefully!

CAUTION

CAUTION

CAUTION! LAMP REPLACEMENT GUIDELINES

LED lamps reflect specific size, shape and overall design. 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.

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: To avoid damaging case when on its side, place a protective blanket, felt or styrofoam between dolly/transporter and case.

Caution Note 2: Place dollys/transporters at underside of each end [not center] of case to prevent damage to case.

Caution Note 3: To avoid oil leaking from condenser unit, lie case down

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.	Remove Front Panel From Case
Slide refrigeration assembly out from under case, and	[Shown Rotated in Below Illustration]
check that no parts have shifted or separated from

INSTALLATION, CONT’D.: CASE STARTUP / CONFIRMING EVAPORATOR COIL FAN DISCHARGE

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.

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.
