Installation

Unpack and inspect contents. Place on level foundation.

Foundation preparation: Ensure level concrete foundation capable of supporting furnace weight.
Electrical connections: Connect 3-phase power supply according to local electrical codes.
Water connections: Connect cooling water supply and return lines.
Gas connections: Connect process gas and quench gas supplies.
Vacuum system: Connect roughing pump and check oil levels.

WARNING! Furnace is heavy; use proper lifting equipment. Ensure all utilities are properly connected and rated for required specifications.

First-Time Setup

Power on furnace; follow initial setup procedure.

System initialization: Power on control system and allow self-test to complete.
Vacuum system check: Perform initial pump-down to verify vacuum integrity.
Temperature calibration: Verify thermocouple readings and calibrate if necessary.
Safety system test: Verify all safety interlocks are functioning properly.
Program setup: Configure basic process programs for common heat treatments.

CAUTION! Only qualified personnel should perform initial setup. Wear appropriate PPE during all operations.

Controls and Settings

Access control system via touchscreen interface. Main controls: POWER, VACUUM START, HEAT START, GAS QUENCH, EMERGENCY STOP.

Programming: Create and modify process recipes with temperature segments, vacuum levels, and gas flows. Safety: Door interlocks, over-temperature protection, water flow monitoring, vacuum safety.

Temperature Control: Setpoints, ramp rates, soak times. Vacuum Control: Pump sequencing, pressure setpoints. Gas Control: Process gas flows, quench gas pressure. System: Calibration, maintenance counters, user access levels.

Connecting Systems

Electrical: 3-phase power connection. Water: Cooling water supply and return. Gas: Process and quench gas connections. Vacuum: Pump connections and gauges.

Ensure all utilities are turned off before making connections.
Verify all connections are tight and leak-free.
Check that all safety devices are properly connected and functional.
Confirm utility specifications match furnace requirements.

Tip: Use thread sealant appropriate for vacuum service on all gas and vacuum connections.

Operating Procedures

Standard heat treatment cycle operation.

Loading: Open door and load parts onto furnace hearth.
Evacuation: Close door and start vacuum pumps to achieve base pressure.
Heating: Start heating cycle according to programmed recipe.
Soaking: Maintain temperature for specified time period.
Cooling: Initiate cooling cycle (furnace cool or gas quench).
Unloading: Vent chamber to atmosphere and remove processed parts.
Shutdown: Follow proper shutdown procedure if furnace will be idle.

WARNING! Never open door when chamber is under vacuum or at high temperature. Always wear heat-resistant gloves when handling hot parts.

Safety Features

Multiple safety systems: Door interlocks prevent operation when door is open. Over-temperature protection automatically shuts off heaters. Water flow monitoring stops operation if cooling is inadequate. Vacuum safety prevents heating if vacuum is insufficient. Emergency stop buttons at multiple locations.

Maintenance & Cleaning

Regular maintenance schedule: Daily visual inspections. Weekly vacuum pump oil checks. Monthly chamber cleaning. Quarterly safety system verification. Annual comprehensive maintenance.

CAUTION! Always disconnect power before performing maintenance. Allow furnace to cool completely before cleaning. Use only approved cleaning materials.

Regulatory Information

Troubleshooting

Symptom	Possible Cause	Corrective Action
Poor vacuum	Leaks or pump issues	Check for leaks; verify pump operation; change pump oil if contaminated.
Heaters not working	Power or element failure	Check power supply; inspect heating elements for damage; verify connections.
Temperature inaccurate	Thermocouple issues	Verify thermocouple connections; calibrate or replace thermocouple.
Water flow alarm	Restricted flow	Check water supply pressure; clean filters; verify pump operation.
Door won't close	Interlock or mechanical issue	Check interlock switches; inspect door mechanism; clear obstructions.

Reset: Control system > Maintenance > Reset alarms after addressing root cause.
