14 Series 0W on 0Hz Engineering Guide Specifications General he liquid source watertowater heat pump shall be a single packaged option heating/cooling unit. he unit shall be listed by a nationally recognized safetytesting laboratory or agency, such as EL esting Laboratory, Underwriters Laboratory (UL), or Canadian Standards Association (CSA). he unit shall be rated in accordance with Air Conditioning, Heating, and Refrigeration Institute/ International Standards Organization (AHRI/ISO) and Canadian Standards Association (CSAUS). he liquid source watertowater heat pump unit, as manufactured by WaterFurnace International, Fort Wayne, Indiana, shall be designed to operate with source liquid temperatures between 0 F [. C] and 0 F [. C] in cooling, and between 0 F [. C] and 0 F [. C] in heating. Casing and Cabinet he cabinet shall be fabricated from heavygauge galvanized steel and finished with corrosionresistant powder coating. his corrosion protection system shall meet the stringent,000 hour salt spray test per ASM B. he interior shall be insulated with / in. thick, multidensity, coated glass fiber for noise suppression. he control box shall have separate holes and knockouts for entrance of line voltage and low voltage control wiring. All factoryinstalled wiring passing through factory knockouts and openings shall be protected from sheet metal edges at openings by plastic ferrules. he control box shall be field switchable from front to back for improved application flexibility with quick attach low voltage harnesses. he control box is shipped standard on the opposite end of the water connections. Refrigerant Circuit All units shall contain two () sealed refrigerant circuits, each containing a hermetic motor scroll compressor, discharge muffler, bidirectional thermal expansion valve assemblies, optional reversing valve, braze plate heat exchangers, factory installed high and low pressure safety switches, freeze detection, service ports, and liquid line filter driers. Compressors shall be scroll types designed for heat pump duty with internal isolation and mounted on rubber vibration isolators. Compressor motors shall have internal overload protection. A high density sound attenuating blanket shall be factory installed around the compressor to reduce sound. Discharge mufflers shall be included to help quiet compressor discharge gas pulsations. he watertorefrigerant heat exchangers shall be interlaced copper brazed, stainless plate steel, capable of withstanding 0 psig [0 kpa] working pressure on the refrigerant side and 0 psig [0 kpa] on the water side. he thermal expansion valve assembly shall provide proper superheat over the liquid temperature range with minimal hunting. he assembly shall operate bidirectionally without the use of check valves for the reversible option. Externally mounted pressure controlled water regulating flow valves are not acceptable. Piping and Connections Supply and return water connections shall be / in. [. mm] FP copper fittings fixed to the cabinet by use of a captive fitting, which eliminates the need for backup pipe wrenches. Optional Back/op Mount Water Connections shall be factory installed to the back corner post or top panel by use of a captive fitting, which eliminates the need for backup pipe wrenches. Electrical WARNING: Warranty is void if strainers are not used on the entering side of the load and source. WARNING: All field installed piping and piping connections must be rated for temperatures greater than 0 F. Materials such as PVC, CPVC, and DWV shall not be used. Controls and safety devices will be factory wired and mounted within the unit. Controls shall include Volt activated compressor contactors, VACVA transformer with built in circuit breaker, reversing valve coils, and anti shortcycle protection. A terminal block with screw in terminals will be provided for field control wiring. o prevent short cycling when the safety controls are activated, the reset relay shall provide a lockout circuit that requires resetting of low voltage supply or main circuit breaker. A lockout signal shall be provided to the display to indicate a lockout situation. Units shall be nameplated for use with time delay fuses or HACR circuit breakers. Unit controls shall be Volt and provide heating or cooling as required by the remote thermostat/sensor. Optional IntelliStart (Compressor Soft Starter) shall be factory installed for use in applications that require low starting amps, reduced compressor startup noise, offgrid, and improved startup behavior. IntelliStart shall reduce normal starting current by 0% on 0 0/0/ units. WaterFurnace works continually to improve its products.
