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.

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.

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.

controller has a factory programmed temperature differential of 7 degrees Fahrenheit.)

Example: Cooling on @ 80 degrees F Cooling off @ 73 degrees F

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

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
