P/N 0420057_B v SAFETY There are two main hazard areas that service technicians may encounter on a day-to-day basis. They are: working within close proximity to the public, and personal safety. Before starting work, review these hazards by completing the following checklist: WORKING NEAR THE PUBLIC ELECTRICAL HAZARDS Are all live electrical hazards protected from public access; i.e.
vi CONTENTS PERSONAL SAFETY Over 90% of accidents are due to human error or from complacency about the job. This checklist is provided to remind you of the potentially hazardous conditions at the jobsite. WORKING AT HEIGHT Will you be working more than six feet off the ground? If yes, have you received appropriate training (i.e.
P/N 0420057_B 1-1 INSTALLATION NSF CERTIFICATION These merchandisers are manufactured to meet ANSI / National Sanitation Foundation (NSF®) Standard #7 requirements. Proper installation is required to maintain certification. Near the serial plate, each case carries a label identifying the type of application for which the case was certified.
1-2 INSTALLATION NOTICE Do NOT remove shipping braces until the merchandisers are positioned for installation. Frames may be damaged. SHIPPING DAMAGE All equipment should be thoroughly examined for shipping damage before and during unloading. This equipment has been carefully inspected at our factory. Any claim for loss or damage must be made to the carrier. The carrier will provide any necessary inspection reports and/or claim forms.
P/N 0420057_B 1-3 Cross-Members Sides Screws (each leg) Shipping Rider for 8 ft Case Screws (two each end of each cross-member) Leg To remove the rider, remove screws attaching each leg to rider. Remove screws holding rider cross-members, then slide cross-members out from between sides. Once cross-members are out, slide the sides out. CASE LEVELING Merchandisers must be installed level to ensure proper operation of the refrigeration system and to ensure proper drainage of defrost water.
1-4 INSTALLATION Leveler Adjustment Position the first case at the highest point. Set a long level (4 ft [1220 mm] or more) on the upper front panel of the case. Use an open-end wrench to turn leg levelers until the case is level from end to end and from front to back. Check all 6 legs on 8 ft (2438 mm) cases, or 8 legs on 12 ft (3658 mm) cases. U Level on Upper Front Panel Note: To avoid removing concrete flooring, begin lineup leveling from the highest point of the store floor.
P/N 0420057_B 1-5 GLASS POSITIONING Check the following to improve opening or closing of the case front glass. 1. Has the case been leveled according to preceding paragraphs? 2. Is the glass handle installed correctly? Verify the glass is bottomed out the length of the handle. A bowed handle indicates the glass may not be bottomed out at the center of the handle. The handle must be removed before it can be repositioned.
1-6 INSTALLATION 4. Is the glass hitting the end or adjacent glass? Slowly open and close the glass to inspect. If the glass is hitting the end or adjacent glass it may not be positioned correctly from left to right. This can be adjusted as follows: ADJUSTMENT BOLT If the glass still does not open or close correctly, adjustment of the top frame may be necessary. This case is equipped with an adjustment bolt at the top rear of the case to raise or lower the glass.
P/N 0420057_B 1-7 4. Remove screws at top of rear door frame. The bottom screws do not need to be removed. 5. Pull back the top of the door frame approximately 2 inches.
