The is a high-efficiency, low back pressure (LBP) refrigeration compressor optimized for natural hydrocarbon refrigerants. Engineered by Huangshi Donper Electrical Appliance Co., Ltd. , this hermetic reciprocating compressor is widely used in commercial cold-chain systems, notably deep freezers and chest coolers with storage volumes ranging from 300 to 350 liters .
: Storage units requiring steady low temperatures. Critical Electrical & Wiring Layout
Approximately 15–25 Ohms (at 25°C ambient)
Use an ohmmeter to check resistance between each of the three pins (C, S, R) and the bare metal housing. Any continuity to the housing means the compressor is grounded and must be replaced. 6. Installation and Replacement Guidelines
Only if you use the to cross-reference capacity, BTU rating, and electrical data. Otherwise, you risk system mismatch. l68wu1 compressor pdf
In the world of refrigeration and HVAC, precise technical documentation is vital for installation, maintenance, and system design. This article focuses on a specific component – the refrigeration compressor – and the practical steps to locate its official PDF resources.

Manufacturers often restrict public access to PDFs to prevent unlicensed repairs. You may need to create a free account on their partner portal. The is a high-efficiency, low back pressure (LBP)
Donper L68WU1 is a high-efficiency refrigeration compressor designed primarily for commercial and household appliances, such as deep freezers and refrigerators with capacities between 300 and 350 liters. It utilizes R290 (Propane)
Check for frost patterns on the evaporator coils. If the compressor shell is hot but the condenser is cold, a refrigerant leak or system restriction is likely. Symptom 3: Loud Hum or Ground Fault Tripping Breaker

Note the factory oil volume (usually around 180ml - 250ml) if you are flushing the system. : Storage units requiring steady low temperatures
operates on a standard single-phase power supply and features a robust reciprocating design. Refrigerant: R290 (Propane) Voltage/Frequency: 220–240V ~ 50Hz Cooling Capacity: 325W (ASHRAE condition) Horsepower: 3/8+ HP Displacement: 6.8 cm³
Always install a new liquid-line filter drier whenever the refrigeration circuit is opened for a compressor swap.
