Single-Stage Heat Pump Heating

The 5TWA4036A4 is a split-system heat pump designed to provide both heating and cooling operation. It uses one ClimaTuff® scroll compressor with single-stage operation and an expansion valve for refrigerant control. Trane's published AHRI rating conditions include high-temperature heating at 47°F outdoor dry-bulb temperature and low-temperature heating at 17°F outdoor dry-bulb temperature.

36,000 BTU/h Cooling Capacity

The 5TWA4036A4 provides 36,000 BTU/h of nominal cooling capacity. The outdoor unit uses a single-stage ClimaTuff® scroll compressor, a direct-drive propeller outdoor fan, and a Spine Fin™ outdoor coil. Its published A-weighted sound power level is 76 dB(A), rated in accordance with AHRI Standard 270.

R-454B Refrigerant & Efficient System Operation

The 5TWA4036A4 uses R-454B refrigerant and an expansion valve for refrigerant control. The outdoor unit is factory supplied with approximately 5 lb. 10 oz. of R-454B refrigerant. Trane specifies 10°F subcooling as the charging specification and notes that proper system charge should always be verified according to the unit nameplate and applicable charging procedure.

460V Three-Phase Split System Design

The 5TWA4036A4 is configured for 460V, three-phase, 60 Hz power and has a published minimum branch circuit ampacity of 6.8 amps with a maximum branch circuit protection rating of 15 amps. The outdoor unit uses a 3/4-inch O.D. gas connection and a 5/16-inch O.D. liquid connection. Trane identifies 25-, 30-, 35-, and 50-foot line sets as available options and recommends consulting its refrigerant piping guidance for applicable line-length and lift requirements.

Controls & Comfort

The 5TWA4036A4 uses single-stage heat pump operation with a direct-drive, single-speed outdoor fan and expansion-valve refrigerant control. The optional TAYASCT501A anti-short-cycle timer is a solid-state timing device designed to prevent compressor recycling until five minutes have elapsed after a satisfied call or power interruption. Trane identifies the timer for applications including commercial installations and long line sets.
