(B) POWER INDICATOR “ON” LIGHT: Your unit is equipped with an on indicator light. When illuminated the on light indicates Power is ON.
(C) CYCLING INDICATOR LIGHT: Your unit is equipped with a cooling system cycle indicator light. When cycle light is “ON”, this indicates your
unit is cooling down to the desired temperature. When the refrigeration compressor is running the cycle light will come “ON” until your unit has
reached the desired temperature, and go “OFF” when your unit has reached desired temperature.
(D) TEMPERATURE DISPLAY: Your unit allows you to select the temperature display in two modes, Actual temperature or Set Point temperature.
Set Point temperature is the Cambro factory default. In circumstances where displaying the Actual temperature is desired the Cambro Air Curtain
Ultra allows you to choose this function. Actual temperature will display internal cabinet temperature acting as an internal thermometer. To switch
between Set-Point and Actual temperature display press and hold the temperature recall button. Display will flash “S” or “A” then display “SET” for
Set-Point or “ACT” for Actual. When display is “SET” or “ACT” release the temperature recall button, to accept the new setting press and release
the temperature recall button.
(E) TEMPERATURE SETTING: Your units operating temperature is PRE-SET at 34°F (1.1°C) with an operating temperature range of 33°F to
38°F ( 0.56°C to 3.33°C). To change temperature, press the up or down arrow temperature setting buttons.
(F) TEMP RECALL: Your unit is equipped with an easy access temp recall button. The temp recall button has two uses.
First is to momentarily display set-point or actual temperature. When your unit is set to display Set-Point temperature press and release the temp
recall button to see actual temperature, display will show actual temperature for 3 seconds then revert back to Set-Point display. When your unit
is set to display actual temperature press and release the temp recall button to see set-point temperature, display will show set-point temperature
for 3 seconds then revert back to actual temperature display. Second, The temp recall button is used to change temperature display between Set-
Point and Actual temperature. Item (D) above describes how to change the display.
(G) DEFROSTING THE EVAPORATOR COIL:
Your unit offers you four defrost options
.
First
is a smart auto defrosting option. Smart defrost is the factory default option and requires you to do nothing, the defrost cycle is automatic. Sensors on the evaporator coil read
coil temperature and decide how long and how often your unit requires defrosting. Depending on usage and environment your unit will defrost in intervals of 4, 6, 8 and 10 hours.
Second
defrost option is a user selected defrost time interval. This will allow you to select defrost time intervals that work best for your operation. You can select unit defrost time
intervals from every 4 hours to every 12 hours in one hour increments. To activate and set your custom defrost option press and hold the manual defrost, up arrow and down arrow
buttons for ten seconds. The controller will beep and display a flashing 4HR, use the up and down arrow button to set your desired defrost interval time. When desired defrost interval
time is reached press the temp recall button to accept your defrost time option. To unselect your timed defrost option repeat same steps and use the up or down arrow buttons until
display shows “OFF”, press the temp recall button to accept. This will revert back to the worry free auto smart defrost option. Important note: If you do select to use the timed interval
defrost option Cambro recommends setting the defrost interval at every 8 hours.
Third
defrost option is a manual forced defrost. This is simply pressing the manual defrost button at any time you need to defrost the evaporator coil. Pressing the manual defrost
button will start a defrost cycle at any time regardless of what defrost option is selected. The light above the manual defrost will illuminate to let you know the unit is in defrost. The
manual defrost button has a second function, when your unit is in a defrost cycle you can terminate the defrost by pressing the manual defrost button, allow two minutes for cooling
cycle to start.
Fourth
defrost option is a hard defrost. This option will start a prolonged defrost cycle and should only be used in case of extreme evaporator ice build up. You should only use the
hard defrost option when instructed to do so by a member of Cambro Customer Service staff.
Cambro Customer Service - 833-935-1091.
During a defrost cycle the indicator light located above the manual defrost button will illuminate. The cooling system condenser/compressor and fans are momentarily disabled. Defrost
feature allows proper defrosting of accumulated ice build up on the evaporator coil. The defrost cycle can be canceled by pressing the manual defrost button. If a defrost cycle is
canceled in this manor there is a ONE minute wait period before the cooling system starts. The controller will display a 60 second countdown indicating the one minute wait period.
During a defrost cycle the condensation from the evaporator coil will flow from the top of the unit down a drain line to the condensate vapor pan. The condensate vapor pan will
automatically evaporate all defrost condensation. There is no need to empty a defrost water pan. Vapor can sometimes be visible and should be considered a normal operating
condition. Proper attention should be given to defrost your unit. Every “Event” or time the unit is used with door open, the coil may build up ice reducing the effectiveness and overall
operation of your unit.
