The Hatco Mini Display Warmer is designed to hold
prepared foods for prolonged periods of time while
maintaining that “just-made” quality. Mini Display
Warmer cabinets provide the best environment for
products like sandwiches, cookies, pretzels, muffins,
and desserts by regulating the air temperature.
The Mini Display Warmer air flow pattern is designed
to maintain consistent cabinet temperature. The heat
sources create a “blanket” effect around the food.
The air flow rate enables the cabinet to rapidly
recover temperature after opening and closing the
door. Configurable access doors and magnetic
adjustable shelves make the Hatco Mini Display
Warmer perfect for any food service application.
The Mini Display Warmer is a product of extensive
research and field testing. The materials used were
selected for maximum durability, attractive
appearance, and optimum performance. Every unit
is inspected and tested thoroughly prior to shipment.
This manual provides installation, safety, and
operating information for the Mini Display Warmer.
Hatco recommends all installation, operating, and
safety information appearing in this manual be read
prior to installation or operation of the Hatco Mini
Display Warmer.
Safety information that appears in this manual is
identified by the following signal word panels:
