Page 5: Moving The Air Conditioner
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. -
Page 6: Operation
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 temperature digital controller. Thermal Edge air conditioners operate as a “closed loop”... -
Page 7: Mounting The Air Conditioner
The condenser fan is controlled by the refrigerant high heat 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. -

Page 16: Preventative Maintenance
Preventative Maintenance Air conditioners require regular cleaning of the condenser air inlet filter. Wash filter often if washable using proper cleaning compound and back flushing the dirt out, or replace if not washable whenever it appears physically dirty. 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. -
