Clearance: Maintain minimum 6-inch clearance on all sides.

WARNING! Furnace reaches extremely high temperatures; install away from combustible materials. Use heat-resistant gloves when handling.

First-Time Setup

Power on furnace; follow initial setup procedure.

Initial Burn-off: Run empty at 500°C for 2 hours to remove manufacturing residues.
Temperature Calibration: Verify temperature accuracy using calibrated thermometer.
Program Setup: Configure default temperature programs if applicable.
Safety Check: Test door interlock and over-temperature protection.

CAUTION! Always wear appropriate personal protective equipment (PPE) when operating furnace.

Operating Procedures

Standard operating procedure for furnace use.

Preparation: Load samples using crucibles or boats.
Programming: Set desired temperature profile.
Start: Close door securely and start program.
Monitoring: Observe temperature display during operation.
Completion: Allow furnace to cool before opening door.
Unloading: Use tongs and heat-resistant gloves.

Tip: Always pre-heat empty furnace to desired temperature before loading samples.

Maintenance

Regular maintenance ensures optimal performance and longevity.

Monthly: Inspect heating elements for damage.
Quarterly: Clean chamber with soft brush or vacuum.
Annually: Calibrate temperature controller.
As needed: Replace damaged insulation or elements.

WARNING! Always disconnect power and allow furnace to cool completely before performing maintenance.

Safety Features

Over-temperature protection: Automatic shut-off if temperature exceeds set point. Door safety interlock: Prevents operation when door is open. Ground fault protection: Electrical safety circuit. Thermal insulation: Reduces exterior surface temperature.

Care & Cleaning

Disconnect power and allow to cool completely before cleaning. Use soft brush or vacuum for chamber cleaning. Wipe exterior with damp cloth.

CAUTION! Never use water or chemical cleaners on hot surfaces. Avoid abrasive materials that could damage insulation.
