3. Rail Cooling Switch
The rail cooling switch is used to adjust the intensity of cooling. When the rail cooling
switch is in the "NORMAL" position, the rail fans operate continuously. When the rail
cooling switch is in the "LOW" position, the rail fans operate continuously when the rail
is cooling down and intermittently when rail cool down is achieved. The "NORMAL"
position is recommended when the rail is actively being used. The "LOW" position is
recommended when not actively preparing food and the rail cover is closed. If not actively
preparing food for a long period such as overnight, seal pans with plastic wrap in addition
to closing the rail cover. Alternatively, seal ingredients and store them in a refrigerator or
freezer.
4. Changing the Temperature Display Scale (°F or °C)
The factory setting is °F. To change the display to °C, follow the steps below.
1) Press and hold both the "SET" button and the "SERVICE USE ONLY" button for
5 seconds. "F5" appears in the display window. (If "F0" is displayed, press the up or
down button repeatedly until "F5" appears.)
2) Press the "SET" button to display the current setting (default: "°F"). Press the up or down
button to switch to °C. Press the "SET" button to save the setting.
3) Press and hold both the "SET" button and the "SERVICE USE ONLY" button
for 5 seconds. The cabinet temperature will be displayed using the newly saved
temperature scale.
4) Affix the "°C" label supplied with the unit to the display panel, covering "°F" but not the
display window.
D. Defrost
1. Cabinet Defrost
This unit is preset at the factory to defrost every 6 hours for general conditions, with the
first defrost occurring 6 hours after the unit is turned on. Note that the defrost is a heated
defrost, and therefore will have a tendency to raise the cabinet temperature. Cabinet
temperature is not displayed during defrost; "dF" is displayed in its place. After defrost,
there is a 5 minute delay before the compressor will start. Defrost may be initiated
manually by holding down the "MANUAL DEFROST" button for 5 seconds.
2. Rail Defrost
Defrost the rail
once a week or more often if needed,
depending on conditions. To defrost the rail, first
remove all pans from the rail and store the contents
properly in a refrigerator or freezer. Move the rail
cooling switch to the "OFF" position and allow the
rail to defrost at room temperature. Do not pour or
spray water into the rail area or try to heat the rail.
Once the frost has melted, wipe the interior of the rail
with a clean, damp sponge or cloth. Empty the rail
condensate pan, then replace it in its proper position.
See Fig. 10. When reinstalling the pan, make sure to
slide it back until it contacts the rear stops.
