work with you if you require additional technical information not provided in this manual.
Inspecting the Equipment
Thermal Edge air conditioning equipment is designed, manufactured and packed to prevent damage
from normal handling, shock and vibration during shipment. It is necessary to inspect your equipment
upon receipt to ensure that there is no visual or hidden damage.
Upon receipt of the equipment, ensure that it is always top side up as indicated by “THIS SIDE UP”
labels. This ensures that the compressor oil is not displaced.
Note: If the equipment has been on its side it must be put upright for at least 24 hours before installing
or running to ensure the compressor oil has returned to the compressor.
All physical damage to packing or signs of damage to the equipment must be noted on the freight bill
of lading. Packages must be opened after receipt and inspected for any internal or concealed damage
to the equipment and to verify proper count and order fulfillment. Delivery without the pallet, not top
side up, other freight on top, damaged or wet should be refused.
Unpacking the Air Conditioner
Always keep air conditioner top up as shown by the packaging label and arrows. If the unit is to be
transported after initial unpacking, place air conditioner back in original packing to prevent damage.
For shipment by UPS or freight carrier, repack as received and re-band to the pallet.
Note: Shipping without being strapped to the pallet may result in tipping and damage, this will void the
warranty.

Moving the Air Conditioners
Read this section completely before running or installing your Thermal Edge air conditioning
equipment.
Note: You will need to perform a Preliminary Test before mounting the air conditioner. Refer to the
Preliminary Test section in this manual for instructions on how to run this test. You will also need to
prepare the enclosure that is to be cooled for mounting in accordance with this manual and the
template supplied.
Note: Thermal Edge air conditioning equipment must be mounted vertically with a minimum of 2” air
space for condenser air return and supply. If necessary, equipment may be mounted at up to a 5
degree angle (rotary compressors) without damaging the compressor.
If air conditioner is to be shipped or transported at any time; pack in original packaging and strap to
pallet to prevent damage. Air conditioner must be kept upright at all times. Air conditioners are not
designed to be shipped attached to an equipment enclosure. Air conditioners shipped which have
internal damage due to shipping while attached to enclosures are warranty voided.
Unit Label
Each air conditioner has a unit label, be sure to record the data from the label to the template below
and keep this information in a safe place for warranty and ordering parts. To prevent damage to
equipment, electrical panel and wiring, and to prevent personal injury, assure that the power source is
compatible with the equipment before operating. When recharging, refrigeration type and amount
must be the same as shown on the unit label or air conditioner will not operate properly or may be
damaged and may result in the warranty voided and UL listing voided.

Operation
Thermal Edge air conditioners will lower (or increase as necessary) the temperature inside an
enclosure to ensure its proper operational temperature. Our air conditioners, when sized properly, will
provide cooling or heating automatically controlled by the digital controller.
Thermal Edge air conditioners operate as a “closed loop” system with no exposure or introduction of
outside air. This ensures that the enclosure is separated from, and is not contaminated with, ambient
air, dirt, chemicals, dust, moisture or foreign matter so that sensitive enclosure components are
protected and are kept at your required operational temperature.
An air conditioner is designed to dehumidify and extract heat from an area, or provide heat to an area.
The cooling is done using a simple refrigeration cycle. A product of this simple refrigeration cycle is
excess humidity that condenses to a liquid.
Thermal Edge air conditioners are designed using an advanced refrigeration cycle and are equipped
with a Condensate Removal System that changes the excess humidity liquid into a vapor which is then
vented to the atmosphere. In the event of excess water vapor when the enclosure door has been left
open there is an overflow hole on the bottom of every unit. Please contact Thermal Edge Inc. if you
encounter excess water coming from your air conditioner.
Preliminary Testing
Before mounting the air conditioner to the enclosure, test for proper operation. Follow the steps below
prior to installation.
WARNINGS
The air conditioner must sit upright for 24 hours to assure the compressor oil has drained down to the
compressor. Check the unit label to assure the electric power available to the air conditioner is the
proper voltage and phase. Check the electric power source for proper ground wire and neutral wire
installation per 2008 NEC. Assure that the electric power is protected by a circuit protection device;
refer to the Unit Specification section in this manual for proper circuit protection sizing.
Plug the unit’s power cord into your source to start the evaporator fan and, if desired, change
the set point. Refer to Digital Temperature Controller Programming section on this manual for
details on changing the set point. Factory default settings should be satisfactory; however you
may want to adjust heat, cooling and alarm set points for your specific application.

The condenser fan is controlled by the refrigerant pressure and will turn on later when the
operating pressure builds up. This feature allows low ambient operation and reduces current
inrush at initial power on.
Run the air conditioner for 15 minutes; during this time the condenser fan will turn on after the
condenser coil warms up. Note: Ambient Temperature must be at least 75°F.
Turn the unit off if the equipment makes any unexpected or hard mechanical noises or
vibrations and refer to the troubleshooting guide in this manual.
The supply cold air should be at least 10°F colder than the return air entering the unit. If it is
not, refer to the troubleshooting guide in this manual;
When you are satisfied that the unit is operating properly, turn unit off, disconnect the power
and mount the unit on the enclosure in accordance with the Mounting the Air Conditioner
section in this manual.
Mounting the Air Conditioner
Using the template supplied, determine where the air conditioner is to be mounted and assure that all
required cuts and holes will not interfere with or damage the enclosure or its contents. Assure that
there is a 3” clearance between walls / obstructions and the air conditioner for the condenser supply
air and return air flow so that it is not restricted. Restricted condenser air flow will affect the air
conditioner’s performance. Mount the air conditioner high on the enclosure in order to cool the hot air
at the top of the enclosure. Position the unit where the cold air can circulate across the width of the
enclosure to cool it all the way across.
Once proper mounting placement is determined, turn the enclosure equipment off, if possible, to
prevent damage. Drill and cut the holes as indicated on the mounting template. Install insulation
gasket as required to ensure an air tight closed loop seal. Be cautious not to let any cutting debris fall
into the enclosure. Attach the hanging bolts as indicated on the template to hold the unit onto the
enclosure and then use the mounting screws that are provided.
Hang the air conditioner on the hanging bolts and from inside the enclosure use the fasteners supplied
to attach the air conditioner to the enclosure. Ensure that these fasteners are tight in order to prevent
the unit from falling off the enclosure. These fasteners should be checked periodically to ensure that
they have not become loose due to vibration.
Ensure that the power supplied is compatible with the air conditioner’s power requirements. Properly
attach the unit’s power cord to a circuit that meets the equipment requirements and provide a circuit
protection device based on the Unit Specifications section of this manual.
After mounting the air conditioner, replace/close the enclosure door and start air conditioner; test for
air leaks to assure a proper closed loop air seal and run test the unit to assure proper operation after
mounting. If any cold air leaks are found, check for proper mounting and apply silicone-free Lexel seal
if leaks persist. Assure that the air conditioner’s condenser inlet air filter is installed properly and
cleaned regularly.

Options
The CS011 Series Air Conditioners may be ordered with the following options. Review the list below
for the specifications and functions of the option(s) that apply to your unit.
Built-in Heater
This unit is configurable to include a Built-in Heater to increase the temperature of your enclosure in
lower temperature conditions. The digital controller is programmed with an individual heater set point
to maintain your enclosure at your desired operating temperature.
Heater capacity available is 350 Watts.
Default Settings:
55°F Heat Set Point
3°F Differential
At the default settings the heater turns on at 52°F and operates until temperature has reached 55°F.
Refer to Digital Temperature Controller Programming section for details on changing these
parameters.
Note: The air conditioner cooling capacity is reduced by 9% at cooling set points below 100°F when
equipped with this option.
Low Ambient
This option consists of circuitry to protect the compressor in a low ambient temperature environment.
The low ambient package is designed to provide an optimum constant low current in the compressor
motor during the non cooling state. This option provides internal heat to the compressor to protect it
from stalls and hard starts during long periods of compressor off state.
Dry Contact
This option provides an early warning capability to your enclosure to aid in the protection of your
expensive equipment. The Dry Contact is programmed with an individual dry contact set point to
monitor the enclosure temperature limit that you require. When the enclosure temperature has
exceeded the maximum limit, the Form C gold plated contact will activate to notify you that there is a
problem in achieving your cooling set point.
Default Settings:
105°F Dry Contact High Temperature Alarm Set Point
2°F Recovery Differential
3min Temperature Alarm Delay
At the default settings the Dry Contact initial conditions are normally open and/or normally closed.
When the unit is powered on and the temperature exceeds 105°F for a period longer than 3 minutes
the Dry Contact will activate. At this time the normally open contact will close and the normally closed
contact will open. This state will remain until the temperature has decreased to 103°F.
Note: The dry contact is not a power status indicator, rather it is a high temperature alarm alerting you
that the unit is unable to meet the cooling set point.

System Faults
If any of the critical control parameters exceed limits, the compressor is turned off and an alarm
condition is indicated on the front panel.
There are three main conditions that can shut the AC compressor down:
The condenser high temperature alarm
The evaporator coil alarm
The compressor thermal overload
In the event that the condenser coil overheats, a condenser high temperature alarm, HA2, will flash on
the display of the digital temperature controller and the compressor will turn off after a 3 minute time
delay.
In the case that the evaporator coil ices up or there is a leak, an evaporator coil alarm, CA, will flash
on the display of the digital temperature controller and the compressor will turn off after a 2 minute
time delay.
A thermal overload protects the compressor against faults. In the event that the snowflake status LED
is not flashing on the display and the compressor is not running, an internal fault may have occurred
on the unit. Refer to the Troubleshooting Guide in this manual.
Digital Temperature Controller Programming
For the end user this section will provide all the necessary information to view and change all functions
and parameters available to you.

Preventative Maintenance
Air conditioners may require regular cleaning of the condenser air inlet section. Restriction to the flow
of air over the condenser coil will degrade the performance of the equipment, cause it to overheat,
reduce cooling and can damage the compressor. The overload switch in the compressor may cause
the compressor to cycle if the condensing coil pressure becomes too high due to air restriction. A
further safety feature is the refrigerant high pressure cut off switch which will stop the compressor if the
condensing pressure becomes too high due restricted condenser air flow or some other cause.
Restricted air flow due to neglecting preventative maintenance will cause unit to repeatedly turn off
and then turn back on after it cools off. An operation in this safety cycling mode will eventually damage the
equipment and void the warranty.
Refer to Field Serviceable Parts section in this manual for details on parts that can be changed to help
increase the uninterruptable life of the Air Conditioner.
Condenser and Evaporator Fans
Thermal Edge air conditioners use high efficiency, long life, sealed ball bearing fans engineered for
optimum performance that require no maintenance. Keep fan blades clean for optimal performance.
Fans are removable and attached by plug-in connections.
Compressor
Thermal Edge uses hermetically factory sealed compressors that are quiet, low vibration and are
maintenance free. Thermal overload devices are installed to protect the compressor from damage
due to overheat and short cycle faults. If the compressor thermal overload fails, it is recommended to
return the unit to Thermal Edge customer service for proper replacement. Note that the rotary
compressor runs with compressed refrigerant gas on the outer case and therefore is hot to the touch.
Loss of Refrigerant
Thermal Edge air conditioners are meticulously leak and run tested after assembly. If a leak in the
system should develop due to shipping damage or mechanical vibration, the leak must be detected,
repaired and the refrigerant charge restored to the system by a qualified refrigeration professional.
Condenser Coils
Depending on the environment the condenser coils may become dirty and the air conditioner may lose
efficiency, causing overheating and diminished cooling capacity. Dirty condensing coils must be backflush cleaned using proper commercial coils cleaning compounds and thorough back-flushing rinsing.
Refer to directions on the cleaning compounds selected. Acid wash is not recommended as it reduces
the life of the coil.
