CAUTION! DO NOT RELY ON THERMOMETERS OR THERMOSTATS FOR PRODUCT (FOOD) TEMPERATURES.

• Thermometers & thermostats reflect air temperatures ONLY.
• For ACTUAL product (food) temperatures, use a calibrated food probe thermometers ONLY.
• For accurate readings, DO NOT use infrared food thermometers.

CAUTION! CHECK CONDENSATE PAN, ITS POSITION & PLUG!
Water on flooring can cause extensive damage!

• Before powering up case, check that condensate pan is positioned directly under case’s condensate drain.
• Before powering up case, check that condensate pan’s electrical plug is SECURELY connected to condensate system’s receptacle.
• If wicking material is used in condensate pan, check that it is secure.

• Caution! Front of cases MUST be flush with each other! After leveling, all cases to be same height.
• Using SCC-supplied nuts & bolts, lightly tighten each of the 5 to 8 bolts in a cross-wise pattern. Work your way around the pattern, tightening more firmly at each pass. Do not firmly tighten one bolt and then start on the next!
• After the cases are bolted together, level the second’ case. Repeat this process for each case to be adjoined.
• After all lined-up cases are level, seal all seams with industrial grade silicone sealant.
• See illustration at top-right.

Glass Shelving
If your unit has glass shelving, it will be packed
separately.

• After case has run for a few minutes, check that temperature starts to drop.
• If temperature controller does not begin cooling (in a few minutes) see temperature controller section in this operating manual for instructions.
• Remote units (without temperature controller on case): Verify that refrigeration requirements listed on serial label (found on the case) are being met.

D. Saturated Suction Temperature (Remote)

• See serial label on case for suction temperature requirements and BTU requirements.
• See serial label on case for defrost schedule and temperature termination parameters.

• Note: Mounting clips MAY be riveted to shelf or header. In such instances, simply remove LED light from mounting clips by pressing against flange part of clips with thumb.

Replacement of LED lights:

• Attach magnetic mounting clips onto LED light.
• Adjust magnetic mounting clips so they are equally spaced on LED light.
• Reattach LED light assembly to its shelf/header.
• Position properly in shelf/header.

Note: If mounting clips are riveted to shelf (or header), attach by placing LED in base of clip and then snapping into clip at FLANGE SIDE.

• Press plug’s barrel-shaped insert deep into LED light.
• Important: If plug is not inserted ALL THE WAY IN the LED light’s orifice, the light may not energize. See “BAD” vs. “GOOD” insertion illustrations below-right.

MAINTENANCE: REFRIGERATION PACKAGE ILLUSTRATION (FROM S.C. MODEL GHSS660R)

Refrigeration Package Configuration

• Illustration shown is from self-contained model GHDSS660R.
• Your particular refrigeration package may have a slightly different layout.

MAINTENANCE: OPTIONAL SLIDING REAR DOORS / PERF. ACRYLIC PLENUM / COND. COIL FILTER

Rear Sliding Doors/Perforated Acrylic Plenum (Optional) is Illustrated Below

• Rear sliding doors have metal brackets connected to perforated acrylic plenums.
• These perforated acrylic plenums are designed to maintain proper refrigerated temperature.
• When sliding rear doors open, the perforatedacrylic plenums also slide open (allowing accessto contents inside case).
• Be sure to completely close the rear sliding doorsafter accessing case contents.

Rear Sliding Door Removal

• Rear sliding doors can be removed WITHOUT removing the perforated acrylic plenum.
• Simply slide rear sliding doors to case center, lift upward and out. Replace in reverse order the doors were removed.

Perforated Acrylic Plenum Removal

• Access perforated acrylic plenums from front of case.
• Simply lift the pieces up and out of case.
• Replace in reverse order they were removed.

Magnetic Condenser Coil Filter

• This filter helps prevent dust particles from entering condenser coil.
• See GENERAL CLEANING (TO BE PERFORMED BY STORE PERSONNEL) section in operating manual for cleaning specifics.

MAINTENANCE: OPTIONAL NIGHT AIR CURTAIN ATTACHMENT & OPERATING INSTRUCTIONS

Optional Night Air Curtain Attachment & Operating Instructions

1. Use caution when handling night air curtain.
2. Display case may come with night air curtain already attached. If not, a retrofit kit will be provided. If using SCC-supplied retrofit kit, place night air curtain on top of case as shown.
3. Grasp the handle and pull downward to desired location OUTSIDE of the acrylic air deflector (see illustration below).
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, carefully return curtain into its housing. Lift night air curtain straight up and off. Note, due to magnet strength, two people may need to grasp each end of night air curtain and lift upward together.
7. Store in safe place, where night air curtain will not be damaged.

NOTE: THE BELOW ILLUSTRATION MAY NOT EXACTLY REFLECT EVERY PARTICULAR CASE’S FEATURES OR OPTIONS.

MAINTENANCE: REAR SWINGINGING/HINGED DOORS (MODEL GHSS1252RLB.6796 ONLY)

GENERAL CLEANING

(TO BE PERFORMED BY STORE PERSONNEL)

(including air deflectors) with a mild soap and water solution and a soft cloth. Caution! Never use ammonia-based cleaners on acrylic. Incorrect cleaning agents or abrasive cleaning cloths cause surface to ‘cloud’ over time.
| Daily| Glass / Mirrors / Shelving : Clean side glass, glass shelves, and mirrors with a household or commercial glass cleaner.
| Daily| Shelves/Decking : Non-glass shelves and decking can be cleaned with a warm soap and water solution and soft cloth.
| Daily| End Panels, Front Panel, Rear Swinging Doors, Toe-Kick, etc. : Wipe off all

surfaces with warm water and mild soap solution and non-abrasive cloth.

| Weekly| Wood, Laminate and Painted Surfaces : Clean with mild soap and water solution and a soft cloth.
| Weekly| Magnetic Condenser Coil Filter :

·         This filter helps prevent dust particles from entering condenser coil.

·         It is accessible at case rear.

·         Clean magnetic condenser coil filter by following either of these steps:

1.    As magnetic condenser coil filter is dishwasher safe, remove from case (no screw removal required) and use a rag or soft-bristled brush to wipe off excess dust particles from filter. Run in normal dishwasher cycle. Remove from dishwasher. Dry with soft cloth or paper towel. Return to case.

2.    If not using dishwasher, remove magnetic condenser coil filter from case. Use a rag or soft-bristled brush to wipe off excess dust particles from filter. Submerse in warm, soapy water. Use soft-bristled brush to remove dust, dirt, grease and grime that may collect on filter. Rinse thoroughly.

3.    Dry with soft cloth or paper towel (as shown below). Return to case.
