If your shop drops below 0°C, the manual allows up to 30% ethylene glycol + 70% distilled water. Never exceed 30%—it reduces specific heat capacity and cooling efficiency.
Ensure the power supply matches the machine's requirements and is properly grounded. For maintenance, wait at least 3 minutes after cutting power to allow electrical discharge. Parameter Settings & Controller Modes The temperature controller typically operates in two modes: cwfl-6000 manual
| Code | Meaning | Immediate Action | |------|---------|------------------| | | High pressure alarm (compressor overload) | Clean condenser fins; check for blocked air exhaust | | E02 | Low pressure alarm (refrigerant leak) | Call technician; add R410a refrigerant | | E03 | Low water flow alarm (L1 circuit) | Check water filter; purge air from pump; inspect hoses for kinks | | E05 | Water temperature too high (>40°C) | Check ambient temp; improve ventilation | | E06 | Water temperature too low (<5°C) | Heater failure (if equipped) or wrong setpoint | | E07 | L2 flow alarm (QBH circuit) | Same as E03 but for second pump | | E10 | Phase sequence error (3-phase models) | Swap any two input power lines | If your shop drops below 0°C, the manual
Troubleshooting guides translate failure modes into diagnostic steps. Effective manuals structure this as: For maintenance, wait at least 3 minutes after
This guide summarizes the essential operational, safety, and maintenance protocols typically found in the . 1. Introduction & Specifications
Providing oscilloscope waveforms or sample logs for intermittent failures helps field engineers replicate and isolate issues.
