**Note**
Near the bottom or on the side of the cabinet, you will find a nipple which is for
condensate overflow. Although all DDB units have built-in condensate management
systems, you may find it necessary to attach a hose to this nipple on enclosures that are
located in extremely humid conditions, when enclosure doors become left open or the
door seals are leaking. Top mount models do not have a built in condensate evaporation
system.
Operating Your System
After installing the unit onto your enclosure and attaching the power cord to a
properly grounded electrical outlet with adequate voltage and current supply, you are
ready to begin operation of the system. As soon as electrical power is supplied to the
unit
, you should hear the cold air stream blower operating immediately. This blower
operates continuously so that the temperature controller can constantly monitor your
enclosure’s internal temperature. Enclosure
temperature will be displayed on the face of
the controller.
If the enclosure temperature is above the factory cooling set point of 80 degrees
Fahrenheit, you will see the cool status LED flashing. This indicates that the
compressor’s automatic off cycle timer is working. (The off cycle timer is factory set at 3-
1/2 minutes.) At the end of 3-1/2 minutes, you should hear the compressor and the
condenser air blower start. This signifies that the cooling system has begun operation to
remove heat and humidity from within the enclosure. (It may take 20 to 30 minutes
operating time to reach full capacity.)
If the heat load within the enclosure is less than the BTUH capacity of the of your Ice
Qube system, you will notice the temperature on the digital display begin to decrease.
When the temperature inside the enclosure decreases 7 degrees Fahrenheit below the
cooling on set point, the compressor and the condenser blower should cycle off, but the
cold air blower will continue to operate, circulating air within the enclosure. (The
controller has a factory programmed temperature differential of 7 degrees Fahrenheit.)
Example: Cooling on @ 80 degrees F Cooling off @ 73 degrees F
Programming the Controller
The digital controller offers many features which you may or may not decide to
use. However, the controller has been programmed at the factory with default settings
for system operations which are satisfactory for many applications. Please review
the
following default settings to see if they are correct for your enclosure application.
1. Cooling system on temperature - 80 degrees Fahrenheit
2. Heating system on temperature - 50 degrees Fahrenheit
(Optional)
3. High enclosure temperature alarm - 100 degrees Fahrenheit
4. Low enclosure temperature alarm - 40 degrees Fahrenheit
5. Audible and Visual alarm - On
6. Digital display in degrees Fahrenheit
7. Filter maintenance alarm - 30 Days
8. High condenser temperature alarm - 170 degrees Fahrenheit
