0 TRIUNE <br />SAFETY SECTION <br />Important— This document contains service <br />information. This is customer property and is to remain <br />with this unit. Please return to service information pack <br />upon completion of work. <br />HAZARDOUS VOLTAGE! <br />Failure to follow this Warning could result in <br />property damage, severe personal injury, or <br />death. <br />Disconnect all electric power, including remote <br />disconnects before servicing. Follow proper <br />lockout/tagout procedures to ensure the power <br />cannot be inadvertently energized. <br />REFRIGERANT OIL! <br />Failure to follow this Warning could result in <br />property damage, severe personal injury, or <br />death. <br />These units use R-410A refrigerant which operates <br />at 50-70% higher pressures than R-22. Use only R- <br />410A approved service equipment. Refrigerant <br />cylinders are painted a "Rose" color to indicate <br />the type of refrigerant and may contain a "dip" <br />tube to allow for charging of liquid refrigerant into <br />the system. All R-410A systems use a POE oil that <br />readily absorbs moisture from the atmosphere. To <br />limit this "hydroscopic" action, the system should <br />remain sealed whenever possible. If a system has <br />been open to the atmosphere for more than 4 <br />hours, the compressor oil must be replaced. Never <br />break a vacuum with air and always change the <br />driers when opening the system for component <br />replacement. For specific handling concerns with <br />R-410A and POE oil, reference Retrofit Bulletin <br />TRN-APG02—EN. <br />HOT SURFACE! <br />May cause minor to severe burning. Failure to <br />follow this Caution could result in property <br />damage or personal injury. <br />Do not touch top of compressor. <br />CONTAINS REFRIGERANT! <br />Failure to follow proper procedures can result in <br />personal illness or injury or severe equipment <br />damage. <br />System contains oil and refrigerant under high <br />pressure. Recover refrigerant to relieve pressure <br />before opening system. <br />GROUNDING REQUIRED! <br />Failure to inspect or use proper service tools may <br />result in equipment damage or personal injury. <br />Reconnect all grounding devices. All parts of this <br />product that are capable of conducting electrical <br />current are grounded. If grounding wires, screws, <br />straps, clips, nuts, or washers used to complete a <br />path to ground are removed for service, they must <br />be returned to their original position and properly <br />fastened. <br />SERVICE VALVES! <br />Failure to follow this warning will result in abrupt <br />release of system charge and may result in <br />personal injury and/or property damage. <br />Extreme caution should be exercised when <br />opening the Suction and Liquid Line Service Valve. <br />Turn valve stem counterclockwise only until the <br />stem contacts the rolled edge. No torque is <br />required. <br />BRAZING REQUIRED! <br />Failure to inspect lines or use proper service tools <br />may result in equipment damage or personal <br />injury. <br />if using existing refrigerant lines make certain that <br />all joints are brazed, not soldered. <br />©2017Ingersoll Rand 4TWL6060A-SUBIA-EN <br />
