Page 7: Chapter 1: Introduction
Real-time power monitoring for individual units • The AIRSYS UNICOOL WPUs are available in cooling capacities from 1.5 - 10 tons; however, the sensible cooling capacity of these machines is as much as 40% higher than a traditional machine. An available ordering guide can help properly match the capacity of the HVAC system to the heat load in the shelter.
Page 8: Using This Manual
• For safety and to achieve the highest levels of performance, always follow the warnings and cautions in this manual when handling and operating the AIRSYS unit. Danger. Emphasizes hazardous conditions that could cause personal injury or death. Warning. Indicates where the operator must proceed with caution to avoid personal injury or damage to property.
Page 9: Model Identification
Each unit is identified by a model number, such as 11V1T3MR410AAC. The elements in the number are explained in Figure 1: Model Number Figure 1: Model Number Contact: AIRSYS North America Phone: (855) 874-5380 Page 9 of 112 Email: ASNSupport@air-sys.com Web: http://airsysnorthamerica.com...
