OPERATING INSTRUCTIONS FOR ALL WW ELECTRIC BURNOUT FURNACES WITH COMPUTERIZED PROGRAMMABLE CONTROLLERS (W13, W14, W18) AND WW COMPUTERIZED PROGRAMMERS (WTNFII-10, -19) Computerized programming of burnout furnaces provides for simple push-button operation for controlling your furnace during the burnout process. All programmers contain 3 built-in burnout programs which may be used immediately by pressing a couple of keys, or you may create your own individualized custom program(s). Your p

FURNACE GRATES & TRAYS For Wax Elimination Cycle The WW Furnace Grate and Tray simplifies burnout procedure. It is no longer necessary to remove flasks and tray, then replace flasks to avoid carbon build-up on heating elements, which is a primary cause of element failure. Now you merely slide the stainless steel tray(s) from beneath the grate at the end of the wax elimination cycle and proceed with burnout. you have removed 90% or more of

INSTALLATION PROCEDURES FOR WW ELECTRIC BURNOUT FURNACES 1) W13 and W14 Furnaces require 240V - 20 Amp dedicated power supply and a NEMA NO: 6-20 receptacle or you can wire in direct with a breaker box nearby (USE A LICENSED ELECTRICIAN). W18 furnaces require 240V – 30 Amp dedicated power supply and a NEMA NO: 10-30 receptacle. 2) Set the furnace on a sturdy bench or table with a fire-proof top. Sides and back must be at least 12" from wall or side equipment. 3) The minimum voltage requi

INSTALLATION FOR WW COMPUTERIZED PROGRAMMERS WTNFII-10 & WTNFII-19 1) Be sure that your programmer is the same voltage as your burnout furnace: WTNFII-10 - 240V WTNFII-19 - 120V Note - Do not plug in furnace or programmer at this time. 2) Mount programmer next to furnace. Holes are provided in the rear of the cabinet for hanging your programmer on the wall with screws. A wall outlet of the proper voltage and amperage with a dedicated line should be within 5 ft.

PLACING FLASKS IN YOUR WW ELECTRIC BURNOUT FURNACE IMPORTANT NOTE: YOU MUST USE EITHER STEAM WAX ELIMINATION OR THE WAX ELIMINATION PROGRAM OF THE FURNACE. REMOVE THE WAX TRAY AFTER THE WAX ELIMINATION CYCLE HAS COMPLETED. FAILURE TO REMOVE THE WAX TRAY WILL CAUSE CARBON BUILD-UP ON THE EXPOSED ELEMENTS RESULTING IN PREMATURE ELEMENT FAILURE. THE ELEMENTS ARE NOT WARRANTED. When starting to load your furnace for wax elimination, be sure to use a tray to catch the melted wax. We

SAFETY RULES The warranty on your WW Electric Burnout Furnace and the WW Computerized Programmer does not cover damage from overfiring, regardless of the circumstances. It is the operator's responsibility to make sure that the furnace turns off at the end of the firing. Follow the safety rules below in addition to the safety rules for your furnace. UNPLUG THE FURNACE WHEN NOT IN USE. DO NOT LEAVE THE FURNACE UNATTENDED NEAR END OF FIRING. WEAR FIRING SAFETY GLASSES WHEN LOOKI

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

PERMANENT PROGRAM NO. 2 [ 5Hr] This program operates the furnace for 1 hour at 300 °°°°F (150 °°°°C) and then advances slowly to 1350 °°°°F (730 °°°°C) over a period of approximately 2 hours, then holds that temperature for 1 hour. The programmer then lowers the temperature to 900 °°°°F (480 °°°°C) in a period of 1 hour and holds that temperature for 3 hours. NOTE: AT THE END OF THE 5 HOUR PROGRAM, WE HAVE BUILT IN 3 EXTRA HOURS OF HOLD TIME IN CASE THE OPERATOR IS NOT READY TO CAST IMME

PERMANENT PROGRAM NO. 3 [ 12 Hr ] Before you use this program, you must first eliminate the wax with either steam or utilize PROGRAM NO. 1. After the wax has been removed you may load the furnace SPRUE HOLE UP or use our WWT13 or WWT18 Grate & Tray and the sprue holes can remain down. REMOVE WAX TRAY AT END OF FIRST HOUR. To start this program, see instructions below. The program begins with a slowly rising temperature from ambient to 1350 °°°°F (730 °°°°C) which requires approximate

We feel that our 12 hour program ( No. 3 ), which is permanently programmed into your controller, is the best and most useful program for the average casting operation. You can load your furnace at 3 - 4 or 5:00 P.M. in the evening and arrive at 7 - 8 or 9:00 A.M. and cast. Many casters prefer to load and cast in a 8 hour workday. We also have a 5 hour program (No. 2) that has worked well for many years with flasks no larger than 4" to 5". Also, you have the option of creating your ow

ENTERING A CUSTOM PROGRAM REMEMBER - ALL PROGRAMMING BEGINS WITH [ ldLE ] ON THE DISPLAY Putting a program into your controller is the easiest way to understand its function. Lets us begin with an 8 hour program. We use a slow steady rise in temperature to a maximum of 1350 °°°°F (730 °°°°C) in all programs (this is suggested by most investment manufacturers); then reduce the furnace temperature down to a casting temperature slowly. Since we only have 8 hours, we will use smaller d
