 SETUP & MAINTENANCE

CALIBRATION:

Your new Miniglaze/2 has been factory calibrated and should not need any adjustment. After long term use of
this furnace there may be some change in the temperature control.  Periodic calibration is necessary to mini-
mize the effects of these changes.

• Place a piece (coupon) of pure silver on the center of a firing tray (on top of a peg).  Using a pair of furnace tongs

place the tray in the muffle.

• Turn the furnace on.

• Set the heat rate knob for slow temperature rise (full counter-clockwise).

• Set the temperature control dial to 960°C (1761°F).

• Allow furnace to reach set point and stabilize for 10 minutes.  Tone will sound or light will illuminate when muffle

temperature is within 10°C (18°F) of the set point.

• If the coupon has not melted turn the calibration screw 1/8 turn clockwise.  Wait 1 minute for furnace to stabilize.

• If coupon remains un-melted, continue rotating calibration screw 1/8 turn clockwise and waiting 1 minute after

each rotation, until silver melts.

• When the silver melts the temperature indicator needle should read 960°C (1761°F).

CLEANING:

• Vacuum dust and dirt from the furnace rather than blow.  This will minimize the amount of airborne dust

particles.

• Use a soft damp cloth to clean the control panel.  Avoid excess water or solution when cleaning the furnace.

Some solutions will attack the panel or electronics and may cause the furnace to malfunction.

REPLACEABLE FUSES:

•  F1:  F 250V / 1.0A
