Cooling System Maintenance: Use only purified water, deionized water, or softened water as the cooling medium. Test water quality quarterly, check pump operation and pipe joint tightness, and replace aging pipes promptly to prevent scale buildup and blockages that could impair heat dissipation.
Cabinet and Circuit Cleaning: Regularly clean dust from the surfaces of components inside the cabinet. Wipe the mainboard, copper plates, and copper bolts with ethanol to prevent dust accumulation from causing insulation degradation and discharge faults. Implement vibration-proofing measures for the cabinet to prevent loosening of terminals.
Load and Component Inspection: Promptly clean accumulated oxide scale from the induction coil. Inspect the induction coil for cracks and insulation damage. Regularly tighten bolts and contactor contacts to prevent poor contact and major accidents.
Maintenance Precautions: Power must be disconnected and the capacitors must be fully discharged before any maintenance is performed. Never directly rinse the control cabinet with water. During humid seasons, implement dehumidification measures. For long-term shutdowns, periodically turn on the machine to dry the circuit.
