User manual CARRIER GT-PX(50YD)

[. . . ] The dual level compressor isolation mounting system, insulated compressor enclosure, and compressor discharge muffler make the 50YEW series one of the quietest water-to-water heat pumps available. The attractive "Euro-style" cabinet allows the unit to fit into any decor. · High temperature scroll compressor, up to 145°F [63°C] leaving water temperature. · Ultra high efficiencies (4. 2 COP at ground loop conditions; up to 5. 5 COP at ground water conditions). [. . . ] Bold outline indicates typical radiant floor application temperatures. Operation below 40°F EWT (source) is based upon 15% methanol antifreeze solution. All performance data is based upon the lower voltage of dual voltage units. Antifreeze for source water is required for operation in the shaded area and all source EWTs below 40°F. 50YEW 202 Carrier : Turn to the Exper ts.

Compressors shall be scroll type designed for heat pump duty and shall be double isolated from the cabinet with two sets of compressor mounting hardware. Compressor motors shall be single-phase PSC with internal over load protection. The coaxial water-to-refrigerant heat exchangers shall be designed for close approach temperatures and be constructed of a convoluted copper (optional cupro-nickel) inner tube and steel outer tube. The brazed plate heat exchanger shall be designed for close approach temperatures and shall be constructed with stainless steel plates. [. . . ] The Flow Controller shall provide 1" pump isolation valves/3-way service valves. The Flow Controller shall be enclosed in a polystyrene case and fully insulated with urethane foam to prevent condensation. Hose Connection Kit (field installed) An accessory hose kit shall provide 150psi [1034 kPa] 1" rubber hose with brass fittings equipped with service pressure/ temperature ports for connection between the unit and Flow Controller. Warranty Information The 2010 standard warranty applies to units ordered on or after July 1, 2010. See Carrier's 2010 Limited Express Residential Warranty Certificate CA234 for specific coverage and limitation. [. . . ]
