TEMPERATURE
L.E.D.
HEAT or COLD INDICATOR L.E.D.
The Indicator L.E.D. will illuminate as the warming
or cooling chamber calls for heat or cold. It will
extinguish when the chamber's interior tempera-
ture reaches the set-point.
PREHEATING or PRECHILLING THE UNIT
Always preheat the warming chamber at 200°F (93°C) for 30 min-
utes before loading the merchandiser with hot food. Always prechill
the cooling chamber at 36°F (2°C) for 60 minutes before loading
with cold food.
LOADING THE CABINET
Load the merchandiser with hot or cold food only. The
purpose of this unit is to maintain hot food or cold food at proper
serving temperature. Use a food thermometer to make certain
all hot food has reached an internal temperature range of 140° to
160°F (60° to 71°C). Do not fill cabinet
closer than 2" from the sensor. Make
certain door is securely closed after load-
ing. Reset the control to 160°F (71°C)
for hot food or 37° to 40°F (3° to 4°C)
for cold food. This will not neces-
sarily be the final setting. Proper temperature range for
the food being held will depend on the type and quantity of
product. It is advisable to periodically check the internal tempera-
ture of each item to assure maintenance of proper food serving
temperature.

ELECTRONIC CONTROL ACCURACY
The electronic control is a precise instrument and is designed to
offer trouble-free service. If you suspect the temperature inside
the cabinet does not match the temperature indicated on the
digital display, after stabilizing, follow the instructions
listed below.
1. Make certain the power meets the requirements of the
appliance, voltage and current rating as indicated on
identification tag.
2. Verify the temperature inside the cabinet with a quality
thermal indicator.
A.
With the exception of the metal shelves, completely
empty the cabinet.
B.
Make certain the sensor, located inside the cabinet at
the ceiling, is completely clean.
C.
Suspend the thermal indicator in the center of the
cabinet.
D.
Allow the temperature, set on the electronic thermostat,
to stabilize for a minimum of one hour before compar-
ing the digital display with the reading on the thermal
indicator.
DO NOT OPEN THE CABINET DOOR(S) DURING THE
TEMPERATURE STABILIZATION PERIOD.
If the reading on the thermal indicator does not match the digital
display within 10°F (6°C), contact a qualified service technician
for appropriate action.
