Carrier Geothermal Heat Pump Systems GT-PW Water-To-Water (50YER) Series Features The GT-PW Water-To-Water (50YER) Series The 50YER water-to-water series offers high efficiency with advanced features, extremely quiet operation and application flexibility at competitive prices. As Carrier’s most adaptable Puron® HFC-410A refrigerant units, the 50YER series can be used for radiant floor heating, snow/ice melt, chilled water for fan coils, potable hot water generation, hot/chilled water for make-up air, and many other types of HVAC applications. [. . . ] Quality control system shall automatically perform via computer: triple leak check, pressure tests, evacuate and accurately charge system, perform detailed heating and cooling mode tests, and quality cross check all operational and test conditions to pass/fail data base. Detailed report card will ship with each unit displaying all test performance data. Note: If unit fails on any cross check, system shall not be allowed unit to ship. Serial numbers will be recorded by factory and furnished to contractor on report card for ease of unit warranty status. Each unit shall be pallet mounted and shipped in clear shrink wrap for visual shipping damage inspection. The units shall be warranted by the manufacturer against defects in materials and workmanship for a period of 10 years on all parts, and 10 years on the compressor and refrigerant circuit parts with a service labor allowance of 5 years for all refrigeration components and 2 years on other parts. An optional extended warranty is available for the units, which increases the labor allowance to 10 years on all parts. Furnish and install Carrier “50YER” Water Source Heat Pumps, as indicated on the plans. Equipment shall be completely assembled, piped and internally wired. Capacities and characteristics as listed in the schedule and the specifications that follow. Casing and Cabinet All units must have multiple access panels for serviceability of compressor compartment. The heat pumps shall be fabricated from heavy gauge galvanized steel with powder coat paint finish and a front access panel. Both sides of the steel shall be painted for added protection. All interior surfaces shall be lined with 1/2 inch [12. 7mm] thick, dual density, acoustic type glass fiber insulation. Insulation placement shall be designed in a manner that will eliminate any exposed edges. Cabinets shall have separate holes and knockouts for entrance of line voltage and low voltage control wiring. All factory-installed wiring passing through factory knockouts and openings shall be protected from sheet metal edges at openings by plastic ferrules. Unit(s) shall have exterior indicator lights showing, 1) compressor operation (on/off) and 2) unit “fault” status. Contractor shall be responsible for providing control circuitry and indicator lights for units not providing this feature. Refrigerant Circuit Units shall have a sealed refrigerant circuit including a high efficiency scroll compressor designed for heat pump operation, a thermostatic expansion valve for refrigerant metering, a reversing valve, coaxial (tube in tube) refrigerant to water heat exchangers, and safety controls including a high pressure switch, low pressure switch (loss of charge), and low temperature sensors. Access fittings shall be factory installed on high and low pressure refrigerant lines to facilitate field service. 120 units shall have 2 independent refrigeration circuits. [. . . ] A high limit and low compressor discharge line temperature switch shall be provided to disable the pump when these conditions occur. Cupro-Nickel Heat Exchanger An optional corrosion resistant CuNi coaxial heat exchanger shall be factory installed in lieu of standard copper construction. Double-Walled Load Heat Exchanger An optional double-walled load side heat exchanger shall be factory installed when unit is dedicated to providing domestic hot water. Flow Controller (field installed) A self-contained module shall provide all fluid pumping, fill and connection requirements for ground-source closed-loop systems up to 20 GPM. [. . . ]
