LOCATION
Good air circulation at the condenser coil in the lower section is necessary to provide proper operation.
The cabinet may be located in any one of the following three ways to assure satisfactory performance.
• The unit can be situated so the lower back section is open to room air, allowing free air discharge.
No side clearance and no top clearance is required. This is the preferred situation and provides
the most effective cooling.
• The unit can be provided with no side clearance, two inches of clearance at the rear, and six inches
of clearance above.
• If the unit is situated with no back clearance and no top clearance, it is necessary to provide either
five inches of clearance on each side or ten inches of clearance on one side of the cabinet.
NOTE: Performance is enhanced when the air going into the condenser coil through the lower front
section is cool. For example, locating the chiller adjacent to an oven would not be recommended.

Probes
During a chill cycle, insert probes in pans of food to
monitor temperatures. Probes should not touch
bottom of pan. Place probe in the middle of the food
for best temperature indication.
The Top Probe in the cabinet corresponds to the left
temperature in the display (Fig. 4); the Center
Probe is second; and the Bottom Probe is the third
temperature in the display.

The cabinet is equipped with a door switch which shuts off the fans and refrigerant valve when the door
is opened. A buzzer sounds and a notice displays: CABINET DOOR OPEN. After the door is closed,
timer and chiller operations resume.
