Having three-phase service brought in for a single rooftop unit can call for major electrical work. The WQE05A1B1AB5A111A1 model avoids that detour: this 4 ton YORK Sun Core \u003cstrong\u003epackaged heat pump\u003c\/strong\u003e (48,000 BTU\/h nominal) runs on 208\/230 V single-phase, 60 Hz.

The WQE series is the standard-efficiency version, with R-454B refrigerant, without factory-installed heat: an electric kit is added in the field according to your needs.\u003c\/p\u003e\n\u003ch3\u003eThe packaged unit, seen from the electrical side\u003c\/h3\u003e\n\u003cp\u003eA packaged heat pump brings the entire system together in a single outdoor cabinet, set on the roof or at ground level and connected to the supply and return ducts of the space. Compressor, coils, indoor blower, filters, control and, where applicable, heating elements share the same cabinet. For your electrician, that means a single main feed to plan for, plus the low-voltage thermostat wiring. There is no separate indoor unit to power and no refrigerant piping to run through the building.\u003c\/p\u003e\n\u003ch3\u003eModel specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePower supply: 208\/230 V single-phase, 60 Hz; allowable applied voltage from 187 V to 252 V\u003c\/li\u003e\n\u003cli\u003eCapacity: 4 tons, that is 48,000 BTU\/h nominal\u003c\/li\u003e\n\u003cli\u003eNet cooling per AHRI: 48,000 BTU\/h\u003c\/li\u003e\n\u003cli\u003eHeating at 47 °F (8.3 °C): 45,600 BTU\/h with a COP of 3.5\u003c\/li\u003e\n\u003cli\u003eHeating at 17 °F (-8.3 °C): 24,600 BTU\/h with a COP of 2.15\u003c\/li\u003e\n\u003cli\u003eEfficiency ratings: 14.0 SEER2, 6.7 HSPF2 and 12.2 EER2\u003c\/li\u003e\n\u003cli\u003eNominal airflow: 1,550 CFM (ft³\/min)\u003c\/li\u003e\n\u003cli\u003eFootprint: 48.9 in. wide, 74.1 in. long and 40.6 in. high (48.9 x 74.1 x 40.6 in.)\u003c\/li\u003e\n\u003cli\u003eOperating weight: 628 lb\u003c\/li\u003e\n\u003cli\u003eOutdoor sound rating per AHRI 270: 78.4 dBA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThese ratings are identical to those of the 4 ton three-phase version: going single-phase costs you neither capacity nor efficiency.\u003c\/p\u003e\n\u003ch3\u003eReference electrical data\u003c\/h3\u003e\n\u003cp\u003eThe YORK technical guide publishes the following values for this configuration (medium static pressure blower, without a powered convenience outlet or a powered exhaust).

It is rated 10.5 kW at 230 V, but delivers only 7.9 kW when the actual voltage is 208 V. We therefore measure the available voltage before confirming your backup heat requirement. The factory non-fused disconnect comes in 60 A and in 100 A; YORK points out that it may be insufficient with certain heat kits. Above 100 A, it has to be removed and an external disconnect of the appropriate size installed.\u003c\/p\u003e\n\u003ch3\u003eA blower and a control designed for this power supply\u003c\/h3\u003e\n\u003cp\u003eThe model number carries a B in the eighth position, which corresponds, in YORK's nomenclature, to the medium static pressure blower. On this single-phase version, the belt-driven centrifugal blower gets a 1.5 HP motor fitted with an adjustable-pitch drive sheave. The high static pressure option is reserved for three-phase models; for demanding ducts, we therefore check the static pressure before confirming this choice.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eSmart Equipment\u003c\/strong\u003e control continuously monitors the voltage supplied to the unit and protects it in the event of a voltage drop or any other electrical deviation. It adds an anti-short-cycle delay, programmable minimum run times and independent fan delays in heating and in cooling. The built-in LCD screen shows the unit status, the supply, return and outdoor air temperatures as well as the fault codes. With a simple USB key, the built-in port makes it possible to retrieve current and previous faults and to update the software. The model code also provides for the BACnet MS\/TP, Modbus and N2 communication card as well as the refrigerant detection system (RDS), which monitors leaks of R-454B, an A2L refrigerant with a low global warming potential.\u003c\/p\u003e\n\u003ch3\u003eConstruction and compatible accessories\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSingle scroll compressor, a single circuit, thermostatic expansion valve (TXV), filter-drier and high and low pressure switches\u003c\/li\u003e\n\u003cli\u003eCoils with copper tubes and aluminum fins; direct-drive outdoor fan, dynamically balanced\u003c\/li\u003e\n\u003cli\u003eFour 16 x 16 x 2 in. filters, MERV 4 as supplied, replaceable with MERV 8 or MERV 13 filters thanks to the tool-less access panel\u003c\/li\u003e\n\u003cli\u003eVertical or horizontal flow economizers offered for all voltages, and powered exhausts in a 208\/230 V single-phase version\u003c\/li\u003e\n\u003cli\u003eLouvered hail guard (kit 1HG0420 for the tall cabinet)\u003c\/li\u003e\n\u003cli\u003e120 V convenience outlet with ground fault circuit interrupter, as a factory option\u003c\/li\u003e\n\u003cli\u003eFull perimeter base compatible with many existing roof curbs, or YORK curbs of 14 in. and 24 in.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat we check before the installation\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eThe capacity of the electrical panel and of the existing single-phase service, with or without backup heat.\u003c\/li\u003e\n\u003cli\u003eThe actual voltage (208 V or 230 V), which determines the heat delivered by the electric kit.\u003c\/li\u003e\n\u003cli\u003eThe condition and the dimensions of the roof curb, as well as the duct openings from underneath or from the side.\u003c\/li\u003e\n\u003cli\u003eThe lift, the service clearances around the cabinet and the condensate drainage.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003eFrom the electrical service to the start-up, AirGreen takes care of everything\u003c\/h2\u003e\n\u003cp\u003eA single-phase packaged heat pump project calls for close coordination between the capacity of the unit, the electrical circuit and the roof.
