II. Operating Instructions and Service Diagnosis
A. Operating Instructions
IMPORTANT
Hoshizaki Counter Showcase is intended for temporary food display. Constructed
with glass, this showcase gives relatively insufficient heat insulation and poor cooling
performance compared with refrigerators in general. For safe and efficient operation,
be sure to follow the instructions below.
1) Do not leave foods in the showcase after service hours, or they may dry or spoil. Foods
that should not dry must be covered or wrapped up in a plastic film.
2) Store only pre-refrigerated items in the showcase. It takes longer for foods to cool in the
showcase than in a refrigerator.
3) Do not leave the doors open or open them too frequently. The interior temperature may
rise, resulting in food deterioration.
4) Do not pack the showcase with foods. The cooling performance may reduce, resulting in
food deterioration.
5) The showcase should not be exposed to direct sunlight or located next to ovens, grills
or other high heat producing equipment. The interior temperature may rise, resulting in
food deterioration.
6) The ambient temperature should not exceed 30°C. The cooling performance may
reduce, resulting in food deterioration.
7) The food mount can be used on either side. The food temperature is controllable by
turning over the food mount to change the distance from the interior bottom.
Normal condition When food freezes
8) The maximum safe height for displaying food products is 9 cm above the interior bottom.
Food products should not be placed above this height as they may not remain cold
enough to avoid spoilage.
