Cwfl-6000 Manual Updated Jun 2026

A manual’s utility depends on clarity and usability. Best practices include:

A: For lasers above 8kW, yes. The internal Y-strainer is only 150 mesh. An external 5-micron sediment filter (not supplied) prevents clogging of the laser’s micro-channel cooling plates.

Drain and replace the cooling water entirely. Debris and bacteria buildup reduce cooling efficiency. cwfl-6000 manual

Open the drain valve at the bottom rear of the chiller. Drain the old water completely. Flush the tank and refill with fresh distilled or purified water.

Never reverse the inlet/outlet connections on the low-temperature circuit. Doing so will starve the QBH of cooling, leading to thermal lensing and permanent fiber damage. A manual’s utility depends on clarity and usability

| Error Code / Issue | Potential Causes | Recommended Solutions | | :--- | :--- | :--- | | No Power | Power cord not connected, blown fuse. | Check power cord connections at both ends. Open electrical panel and replace fuse if needed. | | (Flow Alarm) | Low water level, water pipe obstruction, or kink. | Check water level and add to green zone. Inspect all water pipes for blockages or kinks. | | E05 / E07 (High Water Temp) | Clogged air filter, poor ventilation, high ambient temp. | Clean the filter, ensure minimum clearance around unit, and improve ventilation. | | E03 (High Room Temp) | Excessive heat load, high ambient temperature. | Confirm the chiller's cooling capacity matches the laser's needs; lower room temperature. | | Excessive Water Condensation | Water temperature too low for ambient humidity. | Increase the water temperature or install insulation on water pipes. | | Slow Water Drainage (During Refill) | Fill/vent cap is closed. | Ensure the water fill and vent cap is opened before draining. |

Verify that the local power supply matches the chiller nameplate rating (3-Phase 380V/460V). An external 5-micron sediment filter (not supplied) prevents

Proper installation is critical for safety and performance. The manual outlines the following procedures:
