4 IM 962-2IntroductionIntroductionStandard Unit FeaturesCabinet — Galvanized steel with a durable powder paintfinish. Stamped louvered panels offer 100% protection for thecondenser coil.Compressor — Hermetically sealed scroll compressors.Compressors are mounted on rubber-in-shear pads to reducevibration and noise.Condenser Coil — Constructed with copper tubes andaluminum fins mechanically bonded to the tubes formaximum heat transfer capabilities. All coil assemblies areleak tested at 450 psig internal pressure.Refrigerant Connections — Field piping connections are madethrough a fixed panel. This allows complete access or removal ofaccess panels after piping connections have been made.Crankcase Heater — Standard, all models.Low Ambient Control — A pressure sensitive fan cyclingcontrol to allow unit operation to 0°F is standard.Service Valves — Standard on liquid lines and vapor lines.Service Access — The control box, as well as thecompressor and other refrigerant controls, is accessiblethrough access panels. It may be opened without affectingthe normal operation of the unit. Condenser fan motors areaccessible by removing wire grilles.Filter Drier — Field supplied.Sight glass — Optional, field supplied.Transformer — Step down type, line to 24 volts.Contactor — The contactor is an electrical switch whichoperates the compressor and condenser fans.High Pressure Control — Opens the contactor circuit onhigh refrigerant pressure; manual reset.Low Pressure Control — Stops compressor operation in theevent of loss of refrigerant.Condenser Fan Motor (Direct Drive) — Ball bearing 1075RPM motors are mounted to minimize vibration and noiseproblems.These are permanent split capacitor types andrequire the same capacitance for both run and start.Testing — All units are run tested at the factory prior toshipment. Units are shipped with a holding pressure of nitrogen.Figure 1: RCS 06F & 07F Ton Features
