Refrigeration

• Maintain temperature logs, "open-shift change-close" daily, unusual patterns observed allow scheduling service prior to product loss emergencies
• Keep evaporator coils (cold air) and condenser coils (warm air) clean. Never obstruct airflow of fans
• Never place un-refrigerated or heated product in "designed for storage" equipment, use ice baths or blast chill/freeze equipment
• Do not overstock storage units with product, air should move freely around all items, especially sides and bottom. Cold pans should never be greater than 2/3 full (no mounding), keep pans in place constantly (1 out/1 in)
• Prior to placing a service call, check that power is on and observe temperature pattern for one hour to avoid false alarms (check resets)
• All evaporator coils should be free of ice by visual inspection at all times
• All door gaskets should seal from outside air completely. Gaps will have a big impact on performance. Cold pans should sit in place, no bent corners.
