Pre-Installation Test
Before installing the Ice Qube system on your enclosure, Ice Qube recommends that the unit operates for
20-30 minutes to ensure it is functioning properly. Although the Ice Qube TMS has been tested at the
factory, internal damage may have occurred during shipping which may have not been apparent during the
unpacking inspection.
1. Place the system on a solid base such as a workbench or table. Ensure that the weight of the unit
will be supported. Be sure to allow adequate space for airflow. The cold air supply stream and the
heat rejection air stream must not be restricted.
2. Check that the warm air system filter is in place.
3. Check the data tag for proper electrical requirements. The data tag lists the design voltage and
amperage requirements of the system. Verify that the electrical supply where the system will be
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. See Electrical
Installation Instruction for wiring details. (Page 8)
Note: If any unusual noise or vibration is present during the testing procedure, immediately
disconnect the power and inspect the exterior of the unit for the cause of noise or vibration. If
necessary, Contact Ice Qube immediately to determine cause of the noise/vibration.
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 (27°C). This is due to the fact that the programmable controller has a factory set-point
of 80°F (27°C). The digital display on the face of the controller will be displaying room
temperature. If the display is indicating 80°F (27°C) or warmer, the “Cool” status LED will flash
for 3 ½ minutes before the compressor and the warm air condenser blower will operate. If testing
in low ambient conditions, the condenser fan may come on for a few seconds and shut off. This is
due to a low pressure switch that controls the condenser fan operation. Once system pressure rises
the condenser fan will begin to operate.
Note: If the display is indicating a temperature less than 80°F (27°C), adjust 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 Programming the Standard Controller
in order to
change the factory set points. (Page 11)
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. For room temperatures
above 70°F (22°C), the cool air outlet temperature should be at least 10°F (6°C) colder than the air
inlet temperature. Inlet air temperature will be displayed on the programmable controller. In areas
of high humidity or ambient temperature below 70°F (22°C), the temperature difference may be
less than 10°F (6°C).
6. After completing the above check point, the Ice Qube TMS is ready to be mounted to your
enclosure.
