Paragon 8045-00 Defrost Timer

The Paragon 8045-00 Defrost Timer is a veteran-standard 120V mechanical defrost control designed for heavy-duty commercial refrigeration. This time-initiated, time-terminated unit is engineered to manage electric heat, hot gas, or compressor shutdown defrost cycles with precision. Built with a heavy-duty synchronous motor and a rugged steel enclosure, it handles high-demand 40 Amp, 2 HP switch contacts, ensuring reliable load switching for walk-in coolers and freezers. The positive slider bar switch design maintains electrical integrity by wiping contaminants from contact surfaces during operation. Contractors can easily configure the defrost frequency from 1 to 6 cycles per day, with adjustable defrost duration ranging from 4 to 110 minutes in 2-minute increments. This commercial refrigeration timer is a direct replacement for many older 8000 series models, offering the terminal flexibility needed for quick field install and cabinet integration.

• Universal Compatibility: Serves as a reliable replacement defrost timer for systems requiring electric heat or hot gas defrosting.
• Industrial-Grade Build: Equipped with 40A contacts and a NEMA 1 rated steel enclosure for long-term durability in mechanical rooms.
• Precision Control: Features adjustable trippers for custom scheduling and a copper pointer for accurate back-up termination timing.
• Maintenance Optimized: The slider bar contact design reduces pitting and carbon buildup, extending the life of the internal switching mechanism.

How do I set the defrost frequency on the 8045-00?
Use the included tripper pins on the outer dial. Each pin represents a defrost event; you can set between 1 and 6 events per 24-hour period, ensuring at least 4 hours between each cycle.

Can this unit be used for temperature termination?
The Paragon 8045-00 is primarily a time-terminated model. If your application specifically requires a temperature or pressure-terminated failsafe, verify your wiring against the 8145 series terminal configurations.

What are the electrical ratings for the compressor load?
The internal switches are rated for 2 HP at 120V AC, making it suitable for most standard commercial condensing units and evaporator fan motors.
