connected has the proper capacity. After noting the above, connect power from a properly
grounded electrical connection. The use of an extension cord is not recommended
.
NOTE: If any unusual noise or vibration is present during the testing procedure, immediately
disconnect the power and inspect the unit for the cause of the noise or vibration.
Contact Ice Qube immediately.
4. As soon as power is supplied to the system, the cool air evaporator blower will begin to operate.
The compressor and warm air condenser blower will not operate if the room air temperature is
below 80°F. This is due to the fact the programmable controller has a factory setpoint of 80°F.
The digital display on the face of the controller will be displaying room temperature. If the display
is indicating 80°F or warmer, the “Cool” status LED will flash for 3½ minutes before the
compressor and the warm air condenser blower will operate
.
Note:
If the display is indicating a temperature less than 80°F, adjust the setpoint to a temperature lower
than the room temperature in order for the compressor and warm air condenser blower to operate.
Refer to the “Programming the Controller” section of this manual in order to change the factory set
points.
5. With the compressor and both blowers functioning, allow the unit to operate for 20 to 30 minutes.
This will provide sufficient time for the vapor compression system to achieve equilibrium. Measure
the cool air outlet temperature with an accurate thermometer. This temperature should be at least
10 degrees colder than the inlet air temperature, (if the room temperature is warmer than 70°F).
Inlet air temperature will be displayed on the programmable controller. In areas of high humidity,
the temperature difference may be less than 10 degrees.
6. After completing the above check points, the electrical enclosure is ready to be prepared for the
installation of the Ice Qube system.
PREPARING THE ENCLOSURE:
Ice Qube air conditioning systems have been designed to be light weight for ease of installation. Side
enclosure or vertical mount units have been designed with a simple “two stud” alignment feature to
make initial fastening to the enclosure quick and easy. Lifting lugs are also provided for added
convenience. A few modifications must be made to the enclosure to provide proper airflow, to
maintain enclosure integrity, and to assure a secure installation. Required modifications will vary with
each air conditioner model.
1. Determine the location of the Ice Qube system on the enclosure.
*** CAUTION ***
Verify the weight of the air conditioning system will not cause the enclosure to
become unbalanced. Equipment instability may cause bodily harm or
equipment damage. For units mounted on enclosure doors, confirm the hinges
will support the weight of the Ice Qube system. Refer to system specifications
for model weights.
2.
Upon deciding the location of the Ice Qube system on the enclosure, attach the template to the
enclosure surface. This template drawing will assist the installer in placing the air conditioning unit
on the enclosure. Be sure the Ice Qube system will be mounted level and the cool air inlet and
outlet connections will not be restricted by equipment or shelving within the enclosure. Also check
that the air flow of the warm air stream will not be affected or restricted by the surroundings.
