3 OVERVIEW / TYPE / TEMP / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING - PAGE 1 of 2 OVERVIEW This merchandiser is designed for dry heating operations throughout the product area. The heat is generated from electric rod well warmers as well as ceramic heaters and overhead ceramic metal halide lamps. This merchandiser is designed for display of perishable, unpackaged heated products. This merchandiser IS NOT designed to heat products up; product must be pre-heated PRIOR to its display. Cases should be installed and operated according to this operating manual s instructions to ensure proper performance. Improper use will void warranty. TYPE This unit is designed for the display of products in ambient store conditions where temperatures and humidity are maintained within a specific range. Ambient conditions are to be at 55% max. humidity and maximum temperatures of 75 F (24 C). INTEGRATED AVERAGE PRODUCT TEMPERATURE The Structural Concepts G-Series Service Deli Merchandisers are designed to merchandise product at an integrated average product temperature of 150 Fahrenheit / 66 Celsius. 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! PRECAUTIONS and WIRING DIAGRAMS See next page for PRECAUTIONS and WIRING DIAGRAM information. COMPLIANCE This equipment MUST be installed in compliance with all applicable NEC, federal, state and local electrical and plumbing codes. WARNING ELECTRICAL HAZARD WARNING Risk of electric shock. Disconnect power before servicing unit. CAUTION! More than one source of electrical supply is employed with units that have separate circuits. Disconnect ALL ELECTRICAL SOURCES before servicing. WARNING HOT SURFACE WARNING Pans and Wells Are Hot! Disconnect and allow to cool before cleaning or removing from case. WARNING HOT SURFACE WARNING Ceramic Heaters and Ceramic Metal Halide Lamps Are Hot! Turn Off or Disconnect and Allow to Cool Before Servicing or Replacing. 3

4 OVERVIEW / TYPE / TEMP / 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, CONDITION TYPE, COMPLIANCE and WARNINGS. 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! LAMP REPLACEMENT GUIDELINES Allow to cool before accessing lamps. Lamps are NOT manufactured to resist breakage. Replace with similarly manufactured lamps of same wattage. See Maintenance Fundamentals section in this manual for specifics. 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 FORMAT & LOCATION Each case has its own wiring diagram folded & 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. 4

5 INSTALLATION INSTRUCTIONS Installation Note: Units shown may not depict an exact representation of your particular unit being installed. Slide Skid Out Support required to prevent tipping. 1. Remove Unit From Skid Caution: case must always remain supported or center of gravity will allow case to fall. Slide unit to rear of skid and tip backward off skid. 3. Bolting Adjoined Units View shown is after removal of end panel. Approximate bolt adjoinment locations are illustrated below (balloons 1-5). Factory-determined adjoinment locations will have bolts pre-inserted with nuts/washers provided. Illustration below may not exactly reflect your case. Frame Support Rails 2. Case Aligning, Adjusting and Sealing For service glass to align properly, case must be level and plumb. Shims will be provided with all cases that have frame support rails. Note: After case is in position, it must be sealed to floor to prevent entry or leakage of liquid or moisture. Caution! These units MUST BE sealed to the floor to maintain conformance to equipment mounting standards. Align multiple units. 4. Electrical Connections: Access and Field Wiring See next page

6 ELECTRICAL ACCESS AND CONNECTIONS Installation Instructions, Continued Note: Units shown may not depict an exact representation of your particular unit being installed. 1. Electrical Connections: Access A. Remove lower front panel. No screw removal is required. Simply lift up and off. B. View from back of case with panel removed (showing electrical wire pass-through locations). A C. Remove screws along lower area of electrical box cover. D. Electrical box cover may now be removed. Pass-through for field wiring is now accessible. Also, you may now access terminal block, phase selector switch and other components in raceway. 2. Electrical Connections: Field Wiring Field wiring hook-up / electrical access location is shown in the view below. Unit may be wired single or three-phase. See next page for phase selector instructions. See wiring diagram for additional information. B C D 6

7 PHASE SELECTOR SWITCH (SINGLE-PHASE VS. THREE-PHASE) / PAN PLACEMENT IN WELLS 1. Phase Selector Switch Remove front panel to access. Phase selector switch MUST match your field wiring (either single-phase or threephase). Authorized electrician MUST make determination. See illustrations below. 2. Pan Placement Case is designed to hold several pan sizes. Either 1/3rd wells or full wells may be placed at either front or rear of case. See illustrations at mid-right for 1/3rd size and full-size pans in heated wells.

8 START-UP / LIGHTING / CASE TEMP. / PRODUCT HEATING / SCC TEMPERATURE CONTROLLERS 1. Merchandiser Start-Up Case must be field wired. When power is supplied, throw main power switch at case rear-right and case will power-up. 2. Lighting Overhead light switch is at case rear, right side (see illustration below). 3. Case Temperature Well temperature is dependent upon both the waterless well temperature and the overhead ceramic heater temperatures. Preheat to 170 F on case temperature dial (photo shown below-left) before placing food into case. Caution Temperature reflects internal case temperature ONLY (not product temperature). Use a food probe to determine ACTUAL product temperature! 4. Product Heating Guidelines/SCC Temp. Controllers Well and overhead ceramic heaters are controlled by Structural Concepts Temperature Controllers. These controllers are located on rear wireway cover (as shown in illustration below-right). For proper temperature settings, carefully follow these procedures: Press Preheat as soon as main power switch is turned on. LED indicator will come on. It will shut off on its own. Set both Well and Overhead at 5 to begin. To increase temperature, press the UP key. To decrease temperature, press the DOWN key. If controller is set to 0, relays will de-energize. Setting 1 is minimum heat. Setting 9 is maximum heat. The HEAT LED indicates that the relay is energized and Heater is On. After unit is adjusted, the control will automatically save the user setting approximately 5 seconds after user stops adjusting the setting. Note: During peak usage, slightly higher settings may be required to maintain recommended product heating temperatures.

10 LIGHT FIXTURES Light Fixtures Warning! Disconnect power before providing maintenance & service to unit. Warning! Lamps are NOT manufactured to resist breakage. Replace with same wattage ceramic metal halide lamps (similarly manufactured). If uncertain of wattage, refer to label near rear sliding doors for specifics. Warning! As ceramic heaters may also heat up light fixture area, make certain that entire area has been allowed to cool before touching light fixtures. As ceramic metal halide lamps may take up to 15 minutes to gain full illumination, turn on lamps BEFORE loading product into case. This will allow proper time for proper illumination. Find overhead light switch location on START-UP / LIGHTING / CASE TEMP. / PRODUCT HEATING / SCC TEMPERATURE CONTROLLERS section in manual. Light switch turns on lamps to entire overhead section of case. To access light fixtures, remove fasteners. Then, slide overhead lamp housing toward case center (allowing screw to housing slot) and lower housing down from case. Replace light fixtures as necessary.
