Only trained, qualified installers and service mechanics should install, start up, and service this equipment (Fig. 1). Untrained personnel can perform basic maintenance func- tions such as cleaning coils. All other operations should be performed by trained service personnel. When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment. • Follow all safety codes. • Wear safety glasses and work gloves. • Keep quenching cloth and fire extinguisher nearby when brazing. • Use care in handling, rigging, and setting bulky equipment. . WARNING Electrical shock can cause personal injury and death. Shut off all power to this equipment during installation. There may be more than one disconnect switch. Tag all discon- nect locations to alert others not to restore power until work is completed. WARNING DO NOT USE TORCH to remove any component. System contains oil and refrigerant under pressure. To remove a component, wear protective gloves and gog- gles and proceed as follows: a. Shut off electrical power to unit. b. Recover refrigerant to relieve all pressure from sys- tem using both high-pressure and low pressure ports. c. Traces of vapor should be displaced with nitrogen and the work area should be well ventilated. Refrig- erant in contact with an open flame produces toxic gases. d. Cut component connection tubing with tubing cutter and remove component from unit. Use a pan to catch any oil that may come out of the lines and as a gage for how much oil to add to the system. e. Carefully unsweat remaining tubing stubs when nec- essary. Oil can ignite when exposed to torch flame. Failure to follow these procedures may result in personal injury or death.
