The Ice Merchandiser utilizes a programmable controller to control the temperature and
defrost settings. The controller, which is located on the facade of the unit, is factory set. Please see the default settings sheet and separate instructions that are included on the
operation of this controller.
After shutting the door on freezer models, a short amount of time must be allowed before the door can be reopened. This is due to the tight seal maintained between the door and the cabinet. Waiting a few moments for the pressure to equalize permits the door to be opened easily.
A positive defrost is required to remove frost from the coil in freezer models. This is accomplished by energizing heaters during the defrost cycle that are positioned on the coil surface. The programmable controller is factory set to allow four defrosts per day.
As the preset defrost time is reached, the controller automatically terminates the refrigeration process by turning off the condensing unit and unit cooler fan motors, and energizes the defrost heaters. As the coil temperature increases, the frost begins to melt producing water which runs down the coil to the unit cooler drain pan and exits through the drain tube to the vaporizer. After all the frost has been removed and the coil temperature reaches approximately 50°F [10ºC], the defrost is terminated through the action of the defrost termination control located on the unit cooler, and the refrigeration process resumes.
GENERAL MAINTENANCE
PERIODIC CLEANING
WARNING! To avoid electrical shock, disconnect all electrical power to the merchandiser prior to cleaning
The exterior of the Ice Merchandiser should be wiped with a damp cloth daily. A commercial grade glass cleaner may be used. Do not use a brush, scouring pad or any other abrasive material on the painted surfaces.
The interior (and exterior if desired) may be cleaned with a soft cloth and a mild germicidal detergent. Do not use any
Monthly cleaning of the condenser will aid the heat transfer characteristics of the refrigeration system and increase its efficiency. To accomplish this, remove the bottom facade from the cabinet by removing 2 screws located at the bottom of the facade on each side. Slide facade down off key slots and pull out to remove. Use a bristle brush to loosen any dirt particles that are attached to the fins. Use a vacuum cleaner to remove the loosened particles and other debris. If dirt is noticeable on the fan blades, simply wipe the blades with a damp cloth. Failure to keep the condenser coil clean and clear of obstructions could result in temperature loss and damage to the compressor.
All moving parts have been permanently lubricated and will generally require no maintenance.
