If your building is fed at \u003cstrong\u003e575 V three-phase\u003c\/strong\u003e, this 5-ton YORK WN \u003cstrong\u003epackaged heat pump\u003c\/strong\u003e connects directly to that voltage, with no transformer, and arrives with an economizer already installed at the factory. AirGreen takes on the whole replacement, from the roof survey through to commissioning, in Montreal, Laval, Longueuil, on the North Shore and on the South Shore.\u003c\/p\u003e\n\u003ch3\u003eBefore the replacement: the survey we carry out\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe dimensions and the condition of the existing roof curb, as well as the position of the supply and return openings.\u003c\/li\u003e\n\u003cli\u003eThe 575 V supply, the disconnect and the run of the wiring to the unit.\u003c\/li\u003e\n\u003cli\u003eThe structure and the crane access, including the room to manoeuvre at grade.\u003c\/li\u003e\n\u003cli\u003eThe clear space around the location, including the 72 in. required above the unit to discharge the condenser air.\u003c\/li\u003e\n\u003cli\u003eThe heating and cooling loads of the rooms served, to confirm that 5 tons is the right size.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOne common roof curb from 3 to 5 tons\u003c\/h3\u003e\n\u003cp\u003eIn the KE\/WN series, every model and every configuration shares the same cabinet, the same footprint and therefore the same \u003cstrong\u003eroof curb\u003c\/strong\u003e. YORK points out the benefit: you can install a curb, then choose the capacity and the heating mode once the indoor loads are settled. For your building, that means a future change to the rooms will be made on the same curb, with a 3, 4 or 5 ton model.\u003c\/p\u003e\n\u003cp\u003eA curb designed for another manufacturer or another generation of unit does not necessarily have the same dimensions. During the survey, we compare the existing curb against the YORK template. If needed, we install an 8 in. or 14 in. YORK curb: built to NRCA requirements, these curbs ship knocked down, nest inside the unit's base rails and include a nailing strip and duct supports; a gasket goes on the curb frame and on every duct bearing surface.\u003c\/p\u003e\n\u003ch3\u003eA complete heat pump in the same footprint\u003c\/h3\u003e\n\u003cp\u003eLike the old unit, the WN is a packaged unit: scroll compressor, indoor and outdoor coils, supply blower and condenser fan all sit in a single cabinet set on the roof and tied into the existing ducts. What sets it apart: it works as a heat pump, cools in summer and heats in winter by reversing its cycle, and a field-installed electric heat kit tops up the heat output during deep cold. The connections are made from below, through the roof curb, or horizontally, which makes it easier to adapt to the duct system already in place.\u003c\/p\u003e\n\u003ch3\u003eTechnical data for the WN060C00B5CAACA1A1\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRated capacity: 5 tons (60,000 BTU\/h)\u003c\/li\u003e\n\u003cli\u003eNet AHRI cooling: 56,000 BTU\/h, EER2 of 10.2\u003c\/li\u003e\n\u003cli\u003eHeating at 47 °F (8.3 °C): 52,000 BTU\/h, COP of 3.35\u003c\/li\u003e\n\u003cli\u003eHeating at 17 °F (-8.3 °C): 31,800 BTU\/h, COP of 2.2\u003c\/li\u003e\n\u003cli\u003ePublished seasonal efficiency: 13.4 SEER2 \/ 6.7 HSPF2, that is 14.0 SEER \/ 8.0 HSPF\u003c\/li\u003e\n\u003cli\u003eRated airflow: 1,900 CFM\u003c\/li\u003e\n\u003cli\u003ePower supply: 575 V three-phase, 60 Hz (applied voltage from 540 to 630 V)\u003c\/li\u003e\n\u003cli\u003eDimensions (width x length x height): 44.88 x 82.25 x 32.63 in.\u003c\/li\u003e\n\u003cli\u003eOperating weight: 620 lb (625 lb shipping), without the economizer, which adds 50 lb\u003c\/li\u003e\n\u003cli\u003eOutdoor sound level (AHRI 270): 88 dB(A) in cooling, 86 dB(A) in heating\u003c\/li\u003e\n\u003cli\u003eRefrigerant: R-454B, an A2L with a low global warming potential\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe model offered, the WN060C00B5CAACA1A1, is the only 575 V configuration we carry in this size.

At 575 V, the backup kits offered are the E10, E15, E20 and E30; those of 20 kW and up work in two stages. With the E30 kit, the MCA reaches 48.5 A and the maximum fuse 50 A.

Every alarm flashes a code on the LCD screen and lights the fault indicator on the thermostat, if it has one. The board keeps the last five alarms in memory, even after a power failure, and the USB port gives access to the data logging and the fault history. The \"three times, then stop\" logic keeps a one-off trip of a pressure switch or of a freeze protection from locking out the compressor, which cuts down on needless service calls.\u003c\/p\u003e\n\u003ch2\u003eA turnkey replacement, entrusted to AirGreen\u003c\/h2\u003e\n\u003cp\u003eOur free on-site estimate covers the survey of the existing curb, of the 575 V supply and of the crane access, along with the load calculations.
