Rio Tilt-Pour Automatic Melting Furnace
Operational Safety
Your Rio Tilt-Pour Automatic Melting Furnace is designed to provide safe and efficient operation. Due to the extremely high
heat and molten metal involved in this process, a high degree of caution and care are critical to ensure its safe use. Please
note the following precautions before you proceed with operation of this furnace.
• Warning! Always use appropriate safety equipment, including safety glasses, appropriate heat-resistant gloves, a
fireproof apron and leather-toed shoes (or equivalent) when using this furnace. Molten metal can cause serious injury if
not handled properly and carefully.
• Warning! Keep hands, hair and clothing away from the melting chamber while it is hot. Do not let moisture drip into
the molten metal—a violent reaction may occur. Do not touch the furnace while it is in use or until a sufficient cooling
time has passed (2–3 hours after unit has been turned off). The furnace generates high temperatures that can cause
severe burns or a fire.
Notice: Inspect your crucible for cracks, wear and deterioration prior to every use. Due to high heat, some of the
crucible material will naturally slough off over time and the walls and base will gradually become thinner. This may result
in leaking which can cause element and thermocouple failure.
Notice: Do not set the furnace temperature high enough to grossly exceed the melting point of the metal you are
loading. This could cause boiling and vaporization of the metal resulting in damaging contamination and failure of the
heating element.

Operating the Furnace
Before using your furnace, review the control panel descriptions below and become familiar with its operation.
Setting the Melt Temperature and Handling the Melt
Please Note: This unit is pre-set to Fahrenheit (°F).
1. Remove the crucible and clean the inside with a hard paper towel
to remove loose graphite or other debris. Close the lid and turn the
furnace on. The letters “tESt” will appear on the LED display and the
unit will perform a self-test. Once the test is complete, the current
temperature of the heating chamber will appear.
2. Push the “P” button once to program the set-point temperature.
The letters “SP 1” will appear. You can now adjust the set-point
temperature to your desired temperature by using the “UP” and
“DOWN” keys. Holding a key down for a few seconds allows you to
change the temperature setting more rapidly. When the set-point
temperature is correct, push the “P” button again to save it.
