Installation

Unpack and inspect contents. Place on stable, level surface.

1. Location: Install in well-ventilated area with adequate clearance from combustible materials.
2. Electrical Connection: Connect to appropriate power supply (208-240V AC) using qualified electrician.
3. Ventilation: Ensure adequate room ventilation or connect to exhaust system if required.
4. Grounding: Verify proper grounding according to local electrical codes.

WARNING! Furnace operates at extremely high temperatures; maintain safe clearance from walls and flammable materials. Use heat-resistant gloves when handling hot components.

First-Time Setup

Power on furnace; follow initial setup procedure.

1. Initial Burn-off: Run furnace empty at 1000°C for 2 hours to remove manufacturing residues.
2. Controller Setup: Set temperature units (°C/°F), date/time, and safety parameters.
3. Calibration: Verify temperature calibration using reference thermocouple if required.
4. Test Run: Program simple temperature ramp and verify proper operation.

CAUTION! Always wear appropriate personal protective equipment (PPE) including heat-resistant gloves and safety glasses.

Operating Procedures

Standard operation for heat treatment processes.

1. Preparation: Load samples ensuring adequate clearance from heating elements.
2. Program Selection: Choose pre-set program or create new temperature profile.
3. Start Cycle: Close door securely, press START to begin heating cycle.
4. Monitoring: Observe temperature display and program progress.
5. Completion: Allow furnace to cool naturally or use controlled cooling program.
6. Unloading: Wear heat-resistant gloves, open door carefully, remove samples.

Tip: Always allow furnace to cool below 100°C before opening door for extended periods.

Temperature Programming

Supports complex ramp/soak programs with up to 30 segments.

1. Access Program Mode: Press PROGRAM button on controller.
2. Segment Setup: For each segment, set target temperature, ramp rate, and soak time.
3. Program Storage: Save program to memory for future use.
4. Program Execution: Select program and press START to run.
5. Pause/Resume: Use HOLD function to temporarily pause program.
6. Program Editing: Modify existing programs or create new ones as needed.

WARNING! Do not exceed maximum temperature rating. Monitor program execution closely during initial runs.

Safety Features

Over-temperature Protection: Independent safety controller with separate thermocouple. Door Interlock: Prevents operation when door is open. Power Failure Protection: Program memory retention and safe recovery options.

Maintenance & Cleaning

Disconnect power before maintenance. Allow furnace to cool completely before cleaning.

1. Chamber Cleaning: Remove debris with soft brush or vacuum with HEPA filter.
2. Element Inspection: Check heating elements for damage or sagging monthly.
3. Thermocouple: Verify calibration every 6 months or as required.
4. Exterior: Wipe with damp cloth; avoid abrasive cleaners.

CAUTION! Never use compressed air for cleaning as it can damage insulation and heating elements.
