[. . . ] The large operating map of the scroll compressor allows high temperature operation, up to 145°F [63°C] leaving load water temperature even at 32°F [0°C] entering source water temperature. The combination of a coaxial (tube-in-tube) heat exchanger for the source (ground loop) side and a brazed plate heat exchanger for the load (heating/hot water) side provides very high efficiencies. Integral controls for hydronic heating and domestic water heating avoid the need for external microprocessor-based controls for outdoor temperature reset, warm weather shutdown, staging and other controls. The 50YEW has an extended range refrigeration circuit, capable of ground loop (geothermal) applications as well as open loop (well water) applications. [. . . ] Fault lockout enables emergency heat and prevents compressor operation until thermostat or circuit breaker has been reset. · 10-year limited warranty on major refrigerant circuit components, Optional extended warranties available. · AHRI/ASHRAE/ANSI/ISO 13256-2 certified. · US EPA "Energy Star" compliant. Options & Accessories · Full Condensing Hot Water Generation With Internal Secondary Heat Exchanger and Potable Water Circulating Pump. · Factory Installed "Load" and "Source" Pumps. · Factory Installed Expansion Tanks. · Cupro-Nickel Source Water Coil. · Extended Labor Allowance and Service Warranty.

" Numbers shown with "/" indicate entering/leaving water temperatures. The interior shall be insulated with 1/2" [13mm] thick, multi-density, foil-backed coated glass fiber. Three access panels shall be provided and shall be removable with piping in place. The internal component layout shall provide for major service with the unit in place for restricted access installations. The units shall have an insulated compressor section to minimize the transmission of compressor noise. Refrigerant Circuit All units shall contain Puron® (HFC-410A) sealed refrigerant circuit employing a hermetic motor-compressor, thermal expansion valve, coaxial tube water-to-refrigerant Source heat exchanger, brazed plate Load heat exchanger, compressor discharge muffler, 100% molecular sieve filter drier with XH-11 desiccant, and service ports. An optional Domestic Hot Water mode shall be available. 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 thermal expansion valve shall provide proper superheat over the entire fluid temperature range with minimal "hunting". [. . . ] A circuit breaker protected 75VA transformer shall be employed. Units shall have knockouts for entrance of low and line voltage wiring. Piping Source/Load supply and return water connections, as well as Domestic Hot Water supply and return connections shall be FPT (Female Pipe Thread) copper fittings and shall be securely mounted flush to the cabinet allowing for connection to an MPT (Male Pipe Thread) fitting without the use of a back-up wrench. All Source water piping shall be insulated to prevent condensation at low liquid temperatures. 50YEW 214 Carrier : Turn to the Exper ts.
