Maintenance Schedule

Preventive maintenance ensures long service life and reliability.

Frequency	Maintenance Task
Daily	Check cooling water quality and flow rate
Weekly	Inspect refractory lining for wear and damage
Monthly	Clean electrical connections; check capacitor banks
Quarterly	Calibrate temperature sensors and power meters
Annually	Complete system inspection and refractory replacement if needed

Temperature Control

Precise temperature management for quality results.

Set Temperature: Input desired melting/holding temperature
Ramp Rate: Control heating speed to prevent thermal shock
Hold Function: Maintain temperature for specific durations
Override: Manual temperature adjustment when needed
Monitoring: Real-time temperature display with alarm limits

Tip: Use recommended temperature profiles for different metals.

Emergency Procedures

Immediate actions for emergency situations.

Emergency	Response Procedure
Power Failure	Activate emergency cooling; secure furnace area
Water Leak	Shut off power immediately; stop water flow
Molten Metal Leak	Evacuate area; do not attempt to contain leak
Electrical Fire	Use Class C fire extinguisher; cut power at source
Medical Emergency	Call emergency services; provide first aid if trained

Cleaning and Inspection

Regular cleaning maintains performance and safety.

Exterior: Clean with dry cloth; no liquids on electrical components
Interior: Remove slag and buildup after each campaign
Cooling System: Flush and clean water lines quarterly
Electrical: Blow out dust from cabinets with compressed air

CAUTION! Ensure system is de-energized and cooled before cleaning.

Regulatory Compliance

Furnace complies with international standards: IEC 60519, NFPA 86, OSHA 1910. Electrical safety certification: UL 508A. Environmental compliance: EPA emissions standards. For technical support, contact manufacturer at [email protected] or call 1-800-555-HEAT.

Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
No Power	Circuit breaker, main switch	Check main power supply; reset circuit breakers
Low Melting Rate	Refractory wear, power setting	Inspect refractory; verify power settings
Overheating	Cooling system, ambient temperature	Check water flow and temperature; improve ventilation
Fault Codes	Sensor failure, component issue	Refer to fault code manual; contact service technician
Uneven Heating	Charge distribution, coil alignment	Redistribute charge; check coil positioning

Reset: Control panel > System > Reset to factory defaults if needed.
