This manual will guide you through the installation, maintenance, diagnostics and advance operations of the NE020 & NE030 Series Air Conditioners. This manual contains important information for the end-user who installs, maintains and/or operates the NE020 & NE030 Air Conditioner.
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.
In the event of excess water vapor where 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.
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.

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.
Conditioner has been tested by UL to meet the safety requirements of the UL484 specification. When working with the Thermal Edge Air Conditioner always makes sure shroud is installed. Verify proper voltage is applied to unit as specified in the UL label of the Air Conditioner. In the event of a field service repair, power down unit using the power on/off switch and disconnect power from unit.
