INTRODUCTION:
Ice Qube’s Thermal Management System, TMS, is designed to cool, dehumidify or heat the internal
environment of modern electrical enclosures. Ice Qube offers efficient and aesthetically appealing
packages that can be mounted on top or on the side of your enclosure. Our closed-loop circulation
design protects your equipment from air-borne dust and contaminants which may hinder equipment
operations, causing unnecessary down time. Ice Qube is able to provide cooling capacities from
1,000 to 20,000 BTU per hour - a wide range of cooling systems to satisfy many of your conditioning
needs.
BASIC OPERATION:
The Ice Qube’s Thermal Management System, TMS, is actually a combination of three independent
systems which function simultaneously to maintain environmentally friendly conditions for various
types of electronic equipment enclosures. These three thermal related systems are: the closed-loop
cool air system; the warm air system; and the vapor-compression refrigeration system. Please refer
to Figure 1.
The closed-loop cool air system circulates cold air from the Ice Qube TMS to the electronics
enclosure. This air returns to the Ice Qube system bringing with it unwanted heat and humidity from
inside the enclosure. Heat and humidity is then removed by a heat exchanger located within the Ice
Qube TMS. This heat exchanger is part of the vapor-compression refrigeration system.
At the heart of the vapor-compression refrigeration’s system is a quiet, energy efficient rotary
compressor which circulates environmentally friendly NON-CFC refrigerant. The main purpose of this
compressor is to transfer heat laden refrigerant from the evaporator, located within the closed-loop
cool air system, to a condenser, located in the warm air system. In the warm air system, air is
circulated from the ambient surrounding the enclosure, through a filter, and across the warm air
system heat exchanger. Here, heat from the enclosure is transferred from the warm air heat
exchanger into the warm air stream and dissipated to the ambient.

UNPACKING INSPECTION:
1. The shipping container leaves the factory banded to a pallet with red arrows imprinted on the box.
These red arrows should be pointing in the proper (upward) direction. The Ice Qube TMS is
position sensitive and should remain in an upright position at all times. If the Ice Qube air
conditioner should arrive not banded to a pallet and not in the proper upright position with red
arrows pointing upward, the shipment may have been damaged and you may wish to consider
contacting the freight carrier for instructions on filing a claim.
Note: Operating the unit before maintaining an upright position for 24 hours will void all warranties.
2. Check for any damage to the shipping container. If the shipping container has been damaged or
marred in any way, carefully check to see if the Ice Qube TMS incurred any damage. Check for
scratches, dents, rattles (which may indicate loose components), the presence of oil, and any
other irregularities. Any evidence of damage will need to be recorded on the freight bill and
reported to the carrier. The freight carrier will provide instructions on filing a claim. Ice Qube
cannot accept responsibility for damages that occur during shipping.
PRE-INSTALLATION TEST:
Before installing the Ice Qube system on the enclosure, it is recommended the unit operate for 20 to
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.
NOTE: All Ice Qube Air Conditioners containing an MM or V as part of the model number are designed
to operate in a vertical position only. All Ice Qube Air Conditioners containing a T in the model
number are designed to operate in a horizontal position only.
1. Place the system on a solid base such as a workbench or table. Verify whether the unit is a Top
or a Side Mount air conditioner. Be sure to allow adequate space for airflow. There are two air
streams that must not be restricted, the cool air stream and the warm air stream. Top mount units
must be elevated to provide adequate airflow for the cool air stream located on the bottom of the
system.
Top mount units can only be mounted on a flat horizontal surface. Side mount and Bottom flow
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.
QD-ENG-26 Rev.4
April 2014
-4-
Models with the optional rain or wash down hood do not have a warm air filter and will require
regular routine condenser maintenance.
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 outlet where the system will be
connected has the proper capacity. After noting the above, connect the power cord to 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 cord 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,
(excluding Top mount models – see following note). 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: Top mount unit evaporator blowers are electrically connected to cycle with the
compressor and condenser blower.
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. 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 included template
to the enclosure surface.
This template drawing will assist the installer in placing the air
QD-ENG-26 Rev.4

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 effected or restricted by
the surroundings.
3. Outline the modifications for the enclosure with a marking pencil. Note the bolt hole locations, the
cutouts for the inlet and outlet air streams, the power cord and the locations for any optional
equipment. Additional cable openings may be required for units with optional heating or alarm
outputs, or for units connected to a network communications link.
4. Using a drill, make the holes for the studs, bolts and power cord and any other option. The bit size
will need to vary depending upon the model. Protect any equipment located within the enclosure
from debris produced during the installation procedure.
5. Drill a pilot hole for a saber saw to cut the inlet and outlet air passages. File all cuts to provide a
uniform cutout.
6. Slide the mounting studs through the matching holes in the enclosure. Verify that all of the
openings are aligned. Top mount units do not have mounting studs.
7. After checking that all openings and bolt holes are in alignment, apply the gasket material
provided to the Ice Qube air conditioning system cabinet to ensure enclosure integrity.
*** CAUTION ***
Be careful while removing the backing on the gasket material. The
material may stretch and the holes will not align.
NOTE:
If the enclosure is not air tight or the air conditioning system operates with the enclosure door(s)
open, moisture will condensate inside the air conditioning system and may cause the
condensate management system to overflow.
8. After the gasket material has been installed, mount the Ice Qube system onto the enclosure and
fasten it using the supplied nuts and bolts. Check to see if the power cord and all optional cables
are in place. Fasteners need to be tightened securely and the gasket material needs to be in
place in order to maintain enclosure integrity. The gasket material should be slightly compressed
with no visible gaps. The Ice Qube system is now ready to begin operation.
NOTE:
Near the bottom or on the side of the Ice Qube system cabinet is a nipple for condensate
overflow. Although all vertical or side mounted Ice Qube air conditioners have built-in
condensate management systems, it may be necessary to attach a drain hose to this nipple on
enclosures which are located in extremely humid conditions, or where enclosure doors are left
open or the door seals are leaking.
Top mount models do not have a built in condensate evaporation system. In order for the
drainage system to operate properly, the factory supplied drain kit with a “Tee” must be
installed per factory instructions. Ice Qube cannot be held responsible for improper
installation.
OPERATING THE SYSTEM:
Once the Ice Qube system has been installed onto the enclosure and the power cord has been
attached to a properly grounded electrical outlet with adequate voltage and current supply, the unit is
ready for operation. As soon as electrical power is supplied to the Ice Qube system, the cool air
stream blower will start to operate, (except for Top mount units). 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.
QD-ENG-26 Rev.4
April 2014

If the enclosure temperature is greater than the factory cooling setpoint of 80°F, 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 3½ minutes). At the end of 3½ minutes, the compressor and the condenser air
blower will begin to operate. This signifies that the cooling system has begun operation to remove
heat and humidity from the enclosure. This procedure may take 20 to 30 minutes before it reaches
full capacity.
If the heat load within the enclosure is less than the cooling capacity of the Ice Qube system, the
temperature on the digital display will begin to decrease. When the temperature inside the enclosure
decreases 7 degrees Fahrenheit below the “Cooling on” setpoint, the compressor and the 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 degrees Fahrenheit. Example:
“Cooling on” @ 80°F; “Cooling off” @ 73°F.
Ice Qube also offers two heat options: an External Heat Output (EHO) which provides power to an
external heater typically located within the equipment enclosure; and an Internal Heat Output (IHO)
which provides a heater located within the air conditioning unit. If the enclosure temperature is below
the factory heating setpoint of 50º F, the heat status LED will be ‘”on”. 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 degrees Fahrenheit above the setpoint, 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.
See the label attached to the rear of the air conditioner for maximum wattage
requirement of the heater(s).
PROGRAMMING THE CONTROLLER:
The digital controller has many features that may or may not be required for your application.
However, the controller has been programmed at the factory with typical default settings for
immediate system operation. Please review the following default settings:

5. Optional Alarm Output:
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 exiting the rear (enclosure side) of the air
conditioner. The black wire is common, white is the normally open and red is the normally closed.
6. Sensor Malfunctions:
E-O - Evaporator sensor open
E-C - Evaporator sensor shorted
C-O - Condenser sensor open
C-C - Condenser sensor shorted
NOTE: An alternating E-O … C-O display may indicate the sensor connector has become
disconnected from the rear of the controller.
7. Incorrect Voltage Supply
A continual flashing value of the program version (“3.1x” = x indicates current program version) on
the display screen indicates the supply voltage is either too high or too low.
MAINTENANCE:
The Ice Qube air conditioning system 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 first remove electrical power from the Ice Qube system. Next,
locate the filter cover and filter, (location will vary by model). Slide the filter from the 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 is showing signs of deterioration.
NOTE: If rain or wash down hoods have been installed, a filter would not have been
supplied, therefore no filter maintenance is required. However systems
equipped with rain or wash down hoods will require regular condensing
section maintenance by qualified personnel. For systems equipped with
filters, it is recommended to have a spare clean filter in stock in order to
prevent prolonged cooling system downtime. The dirty filter may be cleaned
at a more convenient time.
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.
QD-ENG-26 Rev.4
April 2014
- 10 -
Maintenance of the condensate management system will require removal of electrical power
from the Ice Qube system and removal of the cover. Please contact Ice Qube before
removing the cover during the warranty period.
*** CAUTION ***
Electrical wires are connected from the cover to the base.
Removing the cover will allow access to the primary condensate management pan, which is
located below the evaporator. Inspect the condensate pan and the drain nipple for signs of
scale, sludge or debris that may prevent water flow through the nipple. To clean the debris
from the pan, use a clean absorbent cloth or shop-vac. Nipples may be cleaned using a ¼
inch tubing brush, then flush with clean water.
Also inspect the neoprene tubing that is attached to the nipples on the condensate
management system. Replace the tubing if it appears to have internal build-up or has become
brittle.
NOTE: If there is a secondary condensate management pan, maintenance will
need to be performed in the same manner as explained above.
After all debris has been removed from the system, replace the cover onto the unit – being
careful not to damage the wiring connecting the cover to the base.
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.
