This preventive maintenance checklist is designed for grocery and supermarket refrigeration systems. It guides technicians through electrical checks, compressor safety controls, suction set points, refrigerant levels, and condenser fan operation. Tasks include inspecting cases and walk-in coolers or freezers, verifying alarms and overrides, checking for refrigerant and oil leaks, ensuring proper airflow, and cleaning the compressor room. The form captures voltage readings, oil conditions, pressure drops across filter driers, and transducer calibration, and it prompts documentation of additional repair items. Ideal for routine store PMs to maintain safe, efficient operation.
