TC Series Compressor Reference Guide Light Commercial Refrigeration Applications www.tecumseh.com
Built for Today. Ready for Tomorrow Throughout its history, Tecumseh Products Company has been a leader in providing customers with efficient and reliable products for commercial and residential refrigeration and air conditioning applications. As a result, equipment manufacturers, wholesale distributors and service contractors continue to demand Tecumseh compressors, condensing units and genuine replacement parts for their specific needs. Following on the path of the current platforms, the TC series compressor delivers best-in-class efficiency, a smaller size envelope and Tecumseh s industry known standard for reliability. PERFORMANCE Suction and discharge systems combined with new motors and refrigerant fluid handling provides improved compressor efficiency. COMPACTNESS Up to 15% lower in height when compared to comparable compressor offerings. VERSATILE Industry standard suction, discharge and process connections facilitate ease of installation and serviceability. PROVEN RELIABILITY ECO-FRIENDLY Designed for optimum performance with green hydrocarbon refrigerant R600a (isobutene) and R290 (propane) A battery of internal and external performance and reliability tests were conducted on the TC prior to releasing any samples for customer testing. Feedback from customer testing also validates the performance and reliability of the TC design. Up to 19% More efficient than the current platforms Up to Lower in height 15% than the current Caution platforms TC must not be used in applications where liquid can enter the compressor

Introduction Product Strategy The TC Series compressor is designed for LBP, L/MBP and M/HBP applications. Compressor models are available for use with refrigerants R600a (isobutene), R290 (propane) in capacities ranging from 300 to 1,500 Btu/h (for LBP and L/MBP) and from 2,000 to 4,000 Btu/h (for M/HBP). Why TC? Tecumseh is pleased to announce the availability of the TC, a high efficiency compressor designed specifically for light commercial refrigeration applications. The TC series is Best-in-Class with respect to performance, energy efficiency and physical size. The TC series compressor meets two (2) important market needs: First, it is optimized for use with eco-friendly refrigerants R600a (isobutene) and R290 (propane) and secondly, the expanded L/MBP and M/HBP operating range allows standardized use across beverage cooler and freezer applications.

Installation Instruction Wiring Diagram Compressors with PTCSCR motor: The motors have a PTC starting device and a run capacitor. Their functioning is similar to the PSC motor. These compressors have a normal starting torque. Compressors with PTCCSR motor: The motor operation is similar to the CSR motor, except for the potential relay, which is replacedby the PTC device. 19
Compressors with RSIR motor: The motors have a normal starting torque and are designed for completely selfequalizing capillary tube systems. Compressors with CSIR motor: The motors have a high starting torque, using an electrolitic starting capacitor. Recommended for applications with capillary tube or expansion valve systems.
