Page 14: Troubleshooting
Troubleshooting FAULT: Furnace Not Turning on. Make sure the furnace is connected to power. Make sure the furnace door is closed, as it has a safety door switch to cut power when the door is open. FAULT: The Error shown below in the picture is coming up on the temperature controller. This is a thermocouple circuit error. - Page 15 Troubleshooting FAULT: The furnace door is not closing properly or is not sealing. Over time the Kaowool in the door may become compacted slightly. This may stop the door from sealing properly when closed due to the micro door switch that is installed. If this happens you can simply screw the connection bolt in more to allow the door to seal correctly.

Page 16: Maintenance
Maintenance Do not place anything closer than 0.5 of a metre to the furnace as this may damage the item or cause damage to the furnace. It is important to keep the bench clean and clear around the furnace. Once every few months or when the furnace is shut down and cool, vacuum out the furnace and the element grooves. -
