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 ammonia-based products as this may damage electrical
components within the unit. Do not use a brush, scouring pad or any other abrasive
material on the painted surfaces. Care should be taken not to wet any electrical
components, connections or controls.
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.
