and have ANSI B9.1 pressure relief valves.OPTION: The evaporator shall have 1 1/2 inch (40 mm) closed cell polyurethaneinsulation in lieu of standard 3/4 inch (19 mm).OPTION: The evaporator shall have left-hand water connection when viewed fromthe control panel.E. Condensers: The remote air-cooled condensers shall consist of a cabinet,condenser coils multiple direct-drive propeller fans, fan guards and mounting legs.The condenser shall have seamless copper tubing mechanically expanded intoaluminum OPTION: copper, plate type fins with full depth collars. The coil shall be“floating tube type” with refrigerant carrying tubes not touching the galvanized endplates. The headers to be field piped. The coil shall have an integral subcooler ratedat ten degrees of subcooling at a 25-degree temperature difference. Coils shall befactory leak tested, dehydrated and connection ends spun closed.Fans shall have heavy gauge aluminum blades with painted steel spiders. Motorsshall be dual voltage, 1140 rpm. OPTION: 830 rpm motors.The condenser shall be factory-equipped with head pressure control consisting of afan motor VFD on one motor with the balance of motors cycled by unit-mountedpressure switches.F. Refrigerant Circuit: The unit shall have two or more refrigerant circuits, completelyindependent of each other. Each circuit shall be equipped with one compressor withintegral oil separator, one microprocessor controller, a factory-mounted controlcircuit transformer, electronic expansion valve, discharge check and shutoff valve,liquid line shutoff valves, replaceable core filter-dryers, sight-glass with moistureindicator. Each circuit shall have field installed refrigerant piping from a dischargeline connection on the indoor unit to the condenser and a liquid return line from thecondenser to a liquid connection on the unit, upstream of the filter-drier. Eachcircuit shall be capable of operating independently; not being disabled in the eventof a fault on the other circuit.OPTION: The compressor shall have a suction service shutoff valveG. Electric Panel: The electric panel shall consist of two separated sections, one forpower components and one for control components. The control section shallcontain a microprocessor controller for each circuit and one for the unit,providing operating and equipment protection controls. The circuit controllersshall operate independently of each other.OPTION: The panel shall include a 115-volt convenience outlet.OPTION: The panel shall be equipped with ground-fault protection.The power section shall include solid state motor starters, a control transformerwith primary and secondary fusing, microprocessor transformers with fusing,standard power blocks for each electrical circuit power connection, andswitches for each circuit pumpdown and unit control power. The control panelshall have a hinged, lockable door.OPTION: The unit shall have power connection to factory-installed, non-fuseddisconnect switches with through-the-door handles for each electric circuit.OPTION: The unit shall have power connection to factory-installed, highinterrupt current rated, non-fused disconnect switches with through-the-doorhandles for each electric circuit.OPTION: The unit shall have a high short circuit rated panel with high interruptcurrent rated, non-fused disconnect switches with through-the-door handles foreach electric circuit.OPTION: The unit shall have single point power connection to a factoryinstalledpower block that is factory wired to a compressor isolation circuitCatalog WGS-1 WGS 130A – 190A 63
