Paragon W14, WTNFII-19, W18, W13 manual PERMANENT PROGRAM NO. 1 - EL, Used For Wax Elimination Only

PERMANENT PROGRAM NO. 1 [ - EL - ]

( USED FOR WAX ELIMINATION ONLY )

The wax elimination program will heat at the rate of 1250 °F (750 °C) per hour for 15 minutes or until the temperature reaches 300 °F (150 °C). NOTE: AS MUCH AS 15 °F (10 °C) OVER- RUN MAY OCCUR. Then the program will hold 300 °F (150 °C) for one hour and turn itself off. You may stop the program at any time by pressing the “STOP” (#) key.

A tray for trapping the wax must be used to protect the floor or hearth plate of the furnace. The tray must be removed before the wax begins to burn or smoke. Once the wax is eliminated, the furnace can be turned off; otherwise it will run for approximately 1¼ hours and then shut off automatically.

During wax elimination, the sprue hole must be down. When the regular burnout cycle is resumed, the flasks should be placed in the furnace with the sprue hole up.

WAX ELIMINATION

Most injection waxes will become liquid at 200 °F (93 °C) or less. However, some pattern waxes and plastics melt as high as 350 °F (176 °C) and plastics burn-out at up to 500 °F (260 °C) and produce odor and fumes. Obviously the plastic patterns must be handled differently than injection wax. High heat and good ventilation. Regular injection waxes can be removed by using PROGRAM NO. 1 WAX ELIMINATION PROGRAM or by using a Steam Wax Eliminator. Wax and plastic burning produces carbon. Carbon build-up on the elements could cause a short that would cause the elements to fail. To prevent this from happening leave the ventilation holes open and occasionally run the Furnace up to it's maximum temperature of 1700 °F (925 °C). The carbon will burn off the elements. We recommend our WWT13 & WWT18 Grate & Trays as an excellent way to extend the life of the elements.
