CL-1, CL-2SAFETY CONSIDERATIONSInstalling, starting up, and servicing air-conditioning componentsand equipment can be dangerous. Only trained, qualified installersand service mechanics should install, start-up, and service thisequipment.When working on the equipment, observe precautions in the liter-ature and on tags, stickers, and labels attached to the equipment.Follow all safety codes. Wear safety glasses and work gloves..WARNINGElectrical shock can cause personal injury and death. Shut offall power to this equipment during installation. There may bemore than one disconnect switch. Tag all disconnect locationsto alert others not to restore power until work is completed.CAUTIONUse care in handling, rigging, and setting bulky equipment.Personal injury could result.WARNINGDO NOT USE TORCH to remove any component. Systemcontains oil and refrigerant under pressure.To remove a component, wear protective gloves and gogglesand proceed as follows:a. Shut off electrical power to unit.b. Recover refrigerant to relieve all pressure from systemusing both high-pressure and low pressure ports.c. Traces of vapor should be displaced with nitrogen andthe work area should be well ventilated. Refrigerant incontact with an open flame produces toxic gases.d. Cut component connection tubing with tubing cutter andremove component from unit. Use a pan to catch any oilthat may come out of the lines and as a gage for howmuch oil to add to the system.e. Carefully unsweat remaining tubing stubs when neces-sary. Oil can ignite when exposed to torch flame.Failure to follow these procedures may result in personalinjury or death.CAUTIONDO NOT re-use compressor oil or any oil that has been ex-posed to the atmosphere. Dispose of oil per local codes andregulations. DO NOT leave refrigerant system open to air anylonger than the actual time required to service the equipment.Seal circuits being serviced and charge with dry nitrogen toprevent oil contamination when timely repairs cannot be com-pleted.
