It has been tested and found to complywith the limits of a Class A computing device as definedby FCC (Federal Communications Commission, U.S.A.)regulations, Subpart J of Part 15, which are designed toprovide reasonable protection against such interferencewhen operated in a commercial environment.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 personal inju-ry or death.AquaForce®30XA080-501Air-Cooled Liquid Chillers
