WARNING: The furnace must be installed properly before operation. Please read and implement the
installation instructions carefully before operating.
GETTING STARTED:
• FIRST TIME ONLY: Plug the power cord to a power circuit. The furnace will go through a series of self-
diagnostic tests. The sound of the plunger being activated will also be heard. The muffle will open.
IMPORTANT! The furnace is shipped with packing material inside the muffle. Remove this material
before any keys are pressed.
Install the ceramic door insulation & positioning ring. Operating the furnace without this platform will
damage the furnace!
Note:If the operation of the furnace causes the lights to "blink" or "flicker" the furnace is on the same
circuit breaker or fuse as the lighting. Correct the problem by connecting the furnace to a different circuit.
Note: The recommended air pressure for most pressing is 4.5 bar and is factory preset to this value. The
air pressure is adjustable by turning the pressure control knob which is located on top of the pressure
regulator.
Note: For a detailed explanation of the Control Panel see the description on page 4.
PRESSING OPERATION (PRESS MODE):
• Press the On/Off Key
The mode selection screen is displayed after 3 seconds:
The muffle temperature is controlled at the Nite Temp setting (see Setup).
At the bottom of the display, 3 menu options are displayed above its particular function key (F2 - F4).
Press (F2) - Listing of press programs - ⊥symbol is used to indicate press programs.
Ceramic (F3)- Listing of conventional ceramic programs 1 thru 100 - no symbol used.
Setup (F4)- Support programs and operations such as set time / date, edit lab name, Language selection
and memory card operations.
