Quarterly Honeycomb: Check honeycomb air diffuser to determine if it is dirty. If dirty, remove from case. See next page for cleaning specifics. 22 PREVENTIVE MAINTENANCE (TO BE PERFORMED BY TRAINED SERVICE PROVIDER) - PAGE 2 OF 3 NOTE: PREVENTIVE MAINTENANCE IS TO BE PERFORMED BY TRAINED SERVICE PROVIDERS ONLY. Preventive maintenance should be performed quarterly (unless conditions warrant a more frequent replacement cycle). Honeycomb Air Diffuser Honeycomb Air Diffuser Removal A. Wedge non-metallic device of suitable strength (such as a ballpoint pen or stylus) between honeycomb and end panel. Caution! Use care not to dislodge the heating wire (that prevents condensation on the honeycomb retainer). B. Apply pressure to collapse the honeycomb to allow it to be pulled out of honeycomb retainer. C. Pry downward & away from honeycomb retainer. Clean honeycomb with warm water and soap solution. Submerse if necessary. Use brush to dislodge stubborn or sticky residue. Dry by using vacuum's `blow mode'. Honeycomb Air Diffuser Installation D. Squeeze honeycomb into the honeycomb retainer. E. Carefully slide honeycomb into place. F. Adjust honeycomb so that it fits flat against retainer. It must not be wavy or out of position.

TROUBLESHOOTING Fan Emits Excessive Noise Call service provider. Case is Not Holding Proper Temperature If a large amount of warm product was added to the case, it will take time for the temperature to adjust. Product must be pre-chilled before placing in case. Check that the case is not in the sun or near a heat or air-conditioning vent. See OVERVIEW / NSF® TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS section in this manual for specifics. If case is located near outside doors, temperature fluctuation can hinder unit's ability to maintain temperature. · Check air return grilles (area at front of decking) for obstructions. · DO NOT set product on air grilles as this will prevent proper airflow! If case still is not holding proper temperature, call service provider. 25 TROUBLESHOOTING (TO BE PERFORMED BY STORE PERSONNEL) - PAGE 2 OF 2 CONDITION TROUBLESHOOTING Case Lights Check that light switch is in the ON position. Not Working · See CASE DESIGN, CONT'D: LED LIGHT SWITCH / LED LIGHTS / THERMOMETER section in manual for switch location (regardless of case design). If case is not hard-wired, check that power cord is properly connected to wall outlet. Check that ALL of the light plugs are properly connected to the LED light. · Plug must be inserted ALL THE WAY into the LED light orifice (with no gap). · See illustrations below-left. Power may not be reaching the case. · Contact store management to have trained service provider perform troubleshooting. · Troubleshooting to be performed by trained service providers only is on next page. If case light still do not come on, it may need to be replaced. · Contact Structural Concepts' Technical Service Department for replacement light (see TECHNICAL SERVICE section of this manual for contact information). · To replace, disconnect plug from existing LED light. Disconnect LED light from its brackets. Replace with new LED light. Insert plug ALL THE WAY into LED light orifice. LED Light Plug Gap No Gap 26 TROUBLESHOOTING (TO BE PERFORMED BY TRAINED SERVICE PROVIDERS ONLY) - PAGE 1 OF 4 CONDITION TROUBLESHOOTING Water Is On The Floor Caution! Disruption of power or malfunctioning condensate pan (or electric coil overflow condensate pan) may cause water to overflow pan and seep onto flooring causing damage! Until condensate pan(s) are functioning (or are replaced), follow these procedures: · Use wet vacuum (or mop & bucket) to remove standing water. · Use `catch pans' for water to drain into. Swap out regularly until case has completely drained. · When power to case is restored, condensate pan should function properly and water will no longer overflow onto flooring. Check that the drain trap is free of debris. Check that the drain PVC is correctly positioned over condensate pan. Check store conditions. To prevent condensation in Type I environments, maximum conditions are to be 55% humidity / 75° Fahrenheit. For Type II environmants, maximum conditions are to be 55% humidity / 80° Fahrenheit. See serial label (at case rear near main power switch) for NSF® Type of your case. Check that electric coil overflow condensate pan is properly plugged in or connected. 27 TROUBLESHOOTING (TO BE PERFORMED BY TRAINED SERVICE PROVIDERS ONLY), PAGE 2 OF 4 CONDITION TROUBLESHOOTING Fans Emit Check that the case is aligned, level and plumb. Excessive Noise Fans Are Not Working Check evaporator fans for cleanliness. Unplug/power off fan motors. Check motor shaft for bearing wear. Check that fan motors are securely mounted in brackets. Verify that fan blades are securely mounted to fan motor. Check that nothing is preventing blade rotation. Check that the fan shroud is properly secured. Check that the MAIN power switch is on. System Not Operating Check that fans are plugged in at the fan shroud. Check for foreign material obstructing fan performance. Check that fan blades freely rotate within fan shrouds Check that power is going to fans Check that fan wiring is connected on terminal blocks. Check that the utility power is on. Check that the MAIN power switch is on. Check the circuit breaker box for tripped circuits. 28 TROUBLESHOOTING (TO BE PERFORMED BY TRAINED SERVICE PROVIDERS ONLY), PAGE 3 OF 4 CONDITION Case Lights Are Not Working TROUBLESHOOTING See TROUBLESHOOTING (TO BE PERFORMED BY STORE PERSONNEL) section in manual (previous sheet) for most common troubleshooting solutions. Check power. · If power is not supplied to the case, facility may have faulty power distribution. · If power is supplied to the case but lights are not energized, case's power supply may be faulty. Case Is Not Holding Temperature If a large amount of warm product was added to the case, it will take time for the temperature to adjust. Unit needs product to be pre-chilled. Temperature changes during defrost mode but will return to normal. Fourth LED will indicate defrost cycle in progress. Check that case is not in sun or near a heat or air-conditioning vent. If case is located near outside doors, temperature fluctuation can hinder unit's ability to maintain temperature. Check that condenser coil has been cleaned. Check that magnetic air filter (attached to rear grille) has been cleaned. See CLEANING SCHEDULE (TO BE PERFORMED BY STORE PERSONNEL) section in operating manual for instructions.
