FILE NO. SVM-10019 1. SAFETY PRECAUTIONS Installing, staring up, and servicing air-conditioning equipment can be hazardous due to system pressures, electrical components, and equipment location (roofs, elevated structures, etc.). Only trained, qualified installers and service mechanics should install, start-up, and service this equipment. Untrained personnel can perform basic maintenance functions such as cleaning coils. All other operations should be performed by trained service personnel.

Use either a flare tool for R410A or conven- tional flare tool. Flare processing dimensions differ according to the type of flare tool. When using a con- ventional flare tool, be sure to secure “dimen- sion A” by using a gauge for size adjustment. Fig. 3-2-1 Flare processing dimensions Table 3-2-3 Dimensions related to
