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 condenser air 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.
