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 3” 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. See Mounting the Air Conditioner for more information.
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.

• Connect a power source to the air conditioner and turn on the power switch. The evaporator fan will start and the digital controller will power up. If cooling is called for, the compressor will start in 3 minutes.

• If desired, change the cooling 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.
Note: The CS011 series is constructed with two condenser coils so that it is permissible to provide less than a 3” clearance for the supply air to one of the coils without affecting 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.
Hang the air conditioner on the easy hang flange and from inside the enclosure use the fasteners supplied to attach the air conditioner to the enclosure. Screw all fasteners hand tight. Then torque to 96 in-lbs. These fasteners should be checked periodically to ensure that they have not become loose due to vibration.
The air conditioner is provided with a power cord or a power terminal block. Ensure that the power supplied is compatible with the air conditioner’s power requirements. Properly connect the unit to a power circuit that meets the equipment requirements and provide a circuit protection device based on the Unit Specifications section of this manual. See Appendix A for Phoenix Contact power connector instructions.
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.
CAUTION
If mounting the air conditioner to the enclosure door, confirm with the enclosure manufacturer that the door’s hinges will support the air conditioner’s added weight (see equipment specifications). Ensure that when the door is fully open that the enclosure will not topple over due to the off- center load.

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.
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.

Refer to the Digital Temperature Controller Programming section for details on changing these parameters.
Celsius Programming
Celsius Programming option allows the user to control the Thermal Edge Air Conditioner in SI units.
This feature can be programmed into the digital temperature controller at time of manufacturing.

• 3°F Differential

At the default settings the heater output turns on at 52°F and operates until the temperature has reached 55°F. Refer to Advanced Digital Temperature Controller Programming section on this manual for details on changing these parameters.
Special Programming
All Thermal Edge Air Conditioners have a Special Programming option for selecting unique preprogrammed settings for special requirements. Although most parameters are accessible in our digital controller, this option allows you to receive a unit preset to your requirements without the need to manually configure the unit. Refer to the Digital Temperature Controller Programming section for details on all default settings.
Open Door Kill Switch
This option provides you with an adjustable and mountable safety switch for your electronics enclosure. This switch will disable power to the air conditioner when your electronics enclosure door is open allowing you to work on your enclosure without the risk of unintentionally powering the unit.
Adjustable Temperature Probe
The adjustable temperature probe provides you with a 12’ temperature probe that can be installed anywhere in your enclosure. This allows you to have the flexibility to monitor and maintain the temperature at any specific location of your enclosure.
Ethernet/IP Controller Output
This option provides the ability to communicate with the Thermal Edge Air Conditioner controller via the Ethernet/IP protocol. You can monitor and control all settings from a remote location with a PLC. Full specifications will be provided with this option. For full details refer to the Ethernet/IP Option Specifications included with the Air Conditioner.
Remote Controller
When having our Programmable Digital Controller mounted on the face of our Air Conditioner does not fit your application, Thermal Edge offers the Remote Controller option. This option moves the controller into your enclosure using a 10’ cable along with a universal, 16 gauge powder coated steel mounting bracket. The Air Conditioner will have no openings on the face of the unit. Below is a partial schematic showing the Remote Controller option wiring connections to the digital controller.

Note: The Remote Controller option is required for high pressure wash-down applications.

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 on, but is not flashing, and the compressor is not running, an internal fault may have occurred.
Refer to the Troubleshooting Guide in this manual.

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. If pressure gauges are connected to the hermetic system, be prepared to replace lost refrigerant resulting from connection and disconnection. It is recommended to use stubby gauges with low loss fittings to minimize refrigerant loss.
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. Periodically remove dust from the components inside the condenser section of the air conditioner with a compressed air blower Very dirty condensing coils must be back-flush 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.
Field Serviceable Parts
Thermal Edge carefully designs and selects components with the maximum life expectancy. Due to OEM manufacturing tolerances, poor unit maintenance or extreme operating conditions, components may fail before their maximum life expectancy. The table below lists parts that are serviceable in the field by an Air Conditioner Technician.
