Pre-Installation Test
Before installing the system on your enclosure, it is a good idea to operate the
unit for a few minutes to ensure it is functioning properly. Although the system has been
tested at the factory, internal damage may have occurred during shipping which may not
have been apparent during the unpacking inspection. This procedure will also help to
familiarize you with the unit.
1. Place the system on a solid base such as a workbench or table. Be sure to allow for
adequate space for airflow. There are two air streams that must not be restricted, the
cold air stream and the warm air stream. Top mount units must be elevated to provide
adequate airflow for the cold air stream located on bottom of system. Check the Model #
to determine whether it’s a Top or Side mount air conditioner.
Top mount units can
only be mounted on a flat horizontal surface and Side mount units can only be
mounted on a flat vertical surface.
2. Check that the warm air system filter is in place. (Location varies with model type)
*
Models with the optional rain or wash down hood do not have this filter and
require regular condenser maintenance.
3. Check the data tag for proper electrical requirements. The data tag will give the
voltage and amperage requirements of the system. Be sure the electrical outlet where
the system will be connected has the proper capacity. After noting the above, connect
the power cord to a properly grounded electrical outlet. An extension cord is not
recommended.
** If any unusual noise or vibration is present during the testing procedure, immediately
disconnect the power cord and inspect the unit for the cause of the noise or vibration and contact
Ice Qube immediately.
4. As soon as power is supplied to the system, the cold air evaporator blower will
begin operation. The compressor and warm air condenser blower will not operate
if the room air temperature is below 80’ F. This is because the temperature
controller has a factory set point 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 3-1/2 minutes before the compressor and
warm air condenser blower will operate.
If the display is indicating a temperature less than 80’ F, you must change the set point
to a temperature lower than the room temperature in order for the compressor and warm
air condenser blower to operate. (Refer to the section on the Temperature Controller in
this manual.)
5. With the compressors and both blowers operating, allow the unit to operate
for 20 to 30 minutes. This will provide sufficient time for the vapor compression
system to achieve operating balance. Measure the cold air outlet temperature
with an accurate thermometer. This temperature should be at least 10’ F colder
than the inlet air temperature if the room temperature is warmer than 70’ F. Inlet
air temperature will be displayed on the temperature controller.
(In areas where
the humidity is high, the temperature difference may be less than 10’ F.)
6. After completing these few simple checks, you are ready to prepare the electrical
enclosure for installation of the unit.
