Introduction
Ice Qube computer and electronics enclosure cooling systems have been designed to provide a safe environment for
your equipment. Our cooling systems provide this environment by cooling and dehumidifying the enclosure that
houses your equipment while providing an efficient, modern, and aesthetically pleasing package requiring minimal
maintenance. Our closed-loop circulation design also protects your equipment from air-borne dust and contaminants
which may hinder your equipment operations and cause unnecessary downtime. Ice Qube offers various models of
cooling systems ranging in cooling capacity from 1,000 to 27,000 BTU per hour to provide air conditioning systems
for many of your environmental needs, including hazardous locations. Ice Qube cooling systems are available in top
and side mount packages.
Basic Unit Operation
The Ice Qube Thermal Management System (TMS) is a combination of several systems that function simultaneously
to maintain environmentally friendly conditions for your equipment within the enclosure. The three main thermal
related systems that we employ are the closed-loop cold air supply stream, the heat rejection air stream, and the
vapor-compression refrigeration system.
The closed-loop cold air supply stream circulates cold air from the Ice Qube TMS to your electronics enclosure.
This air returns to the Ice Qube TMS bringing with it unwanted heat and humidity from inside your enclosure. Heat
and humidity is then removed by a heat exchanger which is part of the vapor-compression refrigeration system.
At the heart of the vapor-compression refrigeration system is a quiet, energy efficient rotary compressor, which
circulates environmentally friendly NON-CFC refrigerant to transfer heat from the heat exchanger (evaporator)
located within the closed-loop air stream to a heat exchanger (condenser) located in the heat rejection air system. In
the heat rejection air stream, air is circulated from the ambient air surrounding the enclosure, through a filter, and
across the warm heat exchanger. Here, heat from the enclosure is transferred from the warm heat exchanger to the
heat rejection air stream and dissipated to the ambient air.

Preservation Instructions
Unpacking Inspection
Caution: It is recommended using gloves and protective eyewear when unpacking
Verify product is as identified on the packing list. Air conditioner should arrive banded to pallet in the proper
upright position. See arrows on packaging for verification. Any evidence of damage should be noted on the freight
bill. The freight carriers claim procedure should be followed. Ice Qube cannot accept responsibility for damages
that occur during shipping. If the shipping container was damaged or marred in any way, check for scratches,
dents, loose hardware, presence of oil or any other irregularities with the Ice Qube TMS.
Package Contents
Included in the shipment with the air conditioner will be:
1. Operation manual
2. Mounting hardware
3. Condenser air diverter plate
4. Standard master warranty
5. Ethernet controller manual (Optional)
6. Enclosure gasket (Pre-installed)
Handling
Ice Qube recommends that the unit remains in the proper upright position, as indicated on the shipping container.
The unit must remain upright for a minimum of 24 hours before initial operation to ensure oil has returned to the
compressor. Operation before the 24-hour time may cause compressor damage and shorten the life of the system.
Operation before this 24-hour period will void all warranties.
Storage
The storage space temperature should be in the range of -40 to 85°C (-40 to 185°F) in a non-condensing
environment.
HAZARDOUS LOCATIONS MODELS ONLY - CONDITIONS OF ACCEPTABILITY:
When installed in the end use equipment, the following considerations are to be examined:
1. The maximum operating temperature of the devices while subjected to the temperature test at a 60°C
ambient air temperature is in accordance with the temperature class of the below table:
Maximum Temperature
T-Code
Unit
120°C
T4A
IQ1-2-3-4-5-6-8-10-12000EV
160°C
T3C
IQ14-17-20000EV
2. The subject devices must be used within their Recognized “Ratings” and conditions of acceptability as
referenced in the User’s Manual.
3. Consideration is to be given to the Conditions of Acceptability specified in the individual recognitions
when these components are employed in the end-use equipment.

5
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.

6
Preparing the Enclosure
Please read entire section before beginning installation. The Ice Qube TMS has been designed to be light in weight
for easy installation. Side mount units have been designed with a simple two stud alignment feature to make initial
fastening to the enclosure quick and easy. A few modifications must be made to your enclosure to provide proper air
flow, maintain enclosure integrity, and assure secure installation. Required modifications will vary with Ice Qube
TMS model.
1. Ensure the mounting surface and enclosure will support the weight of the Ice Qube TMS and will not
become unstable causing bodily harm or equipment damage. For units mounted on enclosure doors,
confirm hinges will support the weight of the Ice Qube TMS. Refer to individual specification drawings for
model weights.
2. Using the specification drawing, determine the ideal location to install the Ice Qube TMS on your
enclosure.
3. Upon deciding the installation location of the Ice Qube TMS on your enclosure, use the cutout drawing to
determine the necessary modifications to your enclosure surface needed to accommodate mounting of the
Ice Qube TMS. An Electronic copy is available at http://www.iceqube.com/downloads/specification-
drawings/
4. Ensure the Ice Qube TMS will be mounted level.
5. Ensure the inlet and outlet of the cold air stream will not be restricted by equipment or shelving within your
enclosure.
6. Check that the air flow of the warm air stream will not be affected or restricted.
7. Confirm the gasket is properly installed to the Ice Qube TMS. This gasket is required to create a seal
against your enclosure and will maintain enclosure integrity. (See Error! Reference source not found. and
Error! Reference source not found.)
Mechanical Installation Instruction
Caution: Protective safety clothing such as helmet, gloves, and steel toe shoes are recommended.
1. Position the Ice Qube TMS so that the two mounting studs are in alignment with the top two 3/8” (9.5mm)
or 1/2" (12.7mm) depending on model, holes in your enclosure surface.
2. Slide the Ice Qube TMS mounting studs through the 3/8” (9.5mm) or 1/2" (12.7mm) depending on model,
holes in your enclosure and check to see that all openings are aligned.

16 nuts and (4, 6 or 8 depending on model) ¼”-20 x 1” bolts supplied with you Ice Qube TMS by hand.
Check to ensure gasket will properly seal the Ice Qube TMS to your enclosure.
4. Using a wrench, tighten the nuts and bolts until the gasket between the air conditioner and the enclosure is
compressed to a maximum thickness of 1/8” (3.175mm). Check the entire perimeter of the gasket/enclosure
interface for compression and seal.
5. The OPTIONAL purge connector is provided as a means to purge harmful gases out of the evaporator
compartment. This ¼” (6.35MM) O.D. push-to-connect fitting is for convenience only and is NOT
REQUIRED as a method of protection. All components are non-ignition source components and DO NOT
require purge protection from any source. (See Figure 2: Push-to-Connect Fitting)
6. The air diverter plate is shipped attached to the condenser outlet below the filter. The air diverter plate can
remain as installed, moved to either of the other 2 sides, or removed entirely for omnidirectional air flow.
7. OPTIONAL Connect external M6x12mm cabinet ground stud to secure earth ground (nut and wire
terminal are provided).

Operating Your System
Once the Ice Qube TMS has been installed onto the enclosure and the power cable has been attached to a properly
grounded electrical connection with adequate voltage and current supply, the unit is ready for operation. As soon as
electrical power is supplied to the Ice Qube TMS, the cool air stream blower will start to operate. The blower will
run continuously so that the controller can monitor the enclosure’s internal temperature. The enclosure temperature
will be displayed on the face of the controller.
If the enclosure temperature is greater than the factory cooling set-point of 80°F (27°C), the “Cool” status LED will
flash. This indicates that the compressor’s automatic off cycle timer is working. The off cycle timer is factory set at
3 ½ minutes. At the end of the 3 ½ minutes, the compressor and the condenser air blower will begin to operate and
the cool LED will be steady. This signifies that the cooling system has begun operation to remove heat and humidity
from the enclosure. The model may take 20 to 30 minutes before it achieves full capacity.
If the heat load within the enclosure is less than the cooling capacity of the Ice Qube TMS, the temperature on the
digital display will begin to decrease. When the temperature inside the enclosure decreases 7°F (4°C) below the
“Cooling On” set-point, the compressor and condenser blower will cycle off. The cool air blower will continue to
operate, circulating air within the enclosure. The controller has a factory programmed temperature differential of 7°F
(4°C). Example: “Cooling On” @ 80°F (27°C); “Cooling Off” @ 73°F (23°C).
Ice Qube also offers an Internal Heat Output (IHO) which provides a heater located within the air conditioner for
ordinary locations only. If the enclosure temperature is below the factory heating set-point of 50°F (10°C), the heat
status LED will be lit. This indicates the heat relay has been energized and is providing power to the heater. There is
no time delay before heating begins. When the temperature of the enclosure rises 7°F (4°C) above the set-point, the
controller will de-energize the heat relay and cycle the heater off.
Note: There is a dead band programmed into the controller that prevents heating and cooling from operating
simultaneously.
Note: See the label of the air conditioner for maximum wattage requirement of the heater. (Ord. Loc. only)
Programming the Standard Controller

Ice Qube offers an optional dry contact alarm output (XO3) that provides both a normally open (close on
alarm) and a normally closed (open on alarm) set of contacts. This alarm signal is provided from a relay
through a 3 conductor cable (Black/Common, White/Normally Open, and Red/Normally Closed) passing through a
strain relief to the left of the internal controller.
6. Sensor Malfunctions:
E-O: Evaporator sensor open
E-C: Evaporator sensor shorted
C-O: Condenser sensor open
C-C: Condenser sensor shorted
Alternating E-O and C-O: Sensor connector disconnected
7. Incorrect Voltage Supply:
A continual flashing value of the program version (“3.1x” where x indicates current program version) on
the display screen indicates the supply voltage is either too high or too low.

15
Maintenance
The Ice Qube TMS is designed to provide many years of trouble-free operation with minimal amount of
maintenance. Primary maintenance consists of checking the condition of the ambient air filter and the condensate
management system.
1. Ambient Air Filter:
It is recommended that the ambient air filter be inspected and cleaned regularly: frequency will depend
upon ambient conditions. To check the condition of the air filter, it is recommended to remove electrical
power from the Ice Qube TMS. Next, locate the filter. Slide the filter from the internal filter rack through
the end slot and clean by soaking in warm soapy water. Rinse with clean water. Use a shop-vac to remove
excess water from the filter before returning it to the system. Replace the filter if it shows signs of
deterioration. See website for air filter cleaning demonstration at http://www.iceqube.com/ice-qube-tv/.
2. Condensate Management System:
The condensate management system should be checked periodically for scale, sludge and debris that may
cause the system to fail. The type of environment will determine the frequency of required maintenance.
Maintenance of the condensate management system will require access to the bottom of the air conditioner.
Removal of the neoprene tubing is necessary. Replacement of the tubing is recommended if it appears to
have internal build-up or has become brittle. Using a soft tube/pipe cleaner, insert into the drain nipple and
move in a circular motion to clear anything that may cause failure.
3. Cooling System Cabinet:
The cooling system cabinet may also need to be cleaned occasionally. To clean the system cabinet, simply
wipe it with a damp, lint free cloth. A mild soap solution may be used if necessary.
Trouble Shooting
Contact Ice Qube if the air conditioning system should fail to operate satisfactorily during the first year of operation.
DO NOT remove the cover without first notifying customer service. Removal of the cover will immediately void
the warranty.
If an operating problem should occur, please review the items outlined on the following page “Trouble Shooting
