Temperature surveillance
Heat sink temperature
The temperature of the heat sink is detected by a
temperature sensor. The temperature surveillance turns
on an internal fan at 140°F to cool down the heat sink and
stop at 131°F. If the temperature exceeds 167°F, the unit
will reduce the power supply to the induction coil by it-self.
If the temperature exceeds 185°F the unit shuts down the
whole power supply and, on the display, appears the error-
code E03.
Ceran glass
The temperature under the Ceran glass is monitored
simultaneously by multiple temperature sensors. If
the temperature exceeds 248°F, the power output is
interrupted. The display will show the error code E04.
Internal temperature of the unit power board
The temperature of the heat sink is detected by a
temperature sensor. The temperature surveillance-lance
turns on an internal fan at 131°F to cool down the heat
sink. If the temperature exceeds 158°F, the unit will reduce
the power supply to the induction coil by itself. If the
temperature exceeds 176°F the unit shuts down the whole
power supply and, on the display, appears the error-code
E06.
Central unit
At 212°F processing temperature, the power output is
interrupted and E30 on the display.

Removing Glass Top
1. Carefully remove glass from the appliance. When glass
is broken, consider applying tape on the glass to hold
the pieces together.
2. NOTICE: Completely scrape off all old silicone sealane
and silicone strips. Residues will prevent proper
bonding of new sealant and will eventually cause
the seal to fail. When the seal fails, it allows water to
penetrate and cause damages to the electronics.
Applying Glass Top
3. Apply degreaser on the frame or wipe clean the
surfaces with isopropyl alcohol.
4. Apply a line of PACTAN around the frame.
5. Wipre clean the silicone strips with isopropyl alcohol.
Then place the strips around the frame. DO NOT
OVERLAP.
6. Apply a line of PACTAN on the silicone strips.
7. Set in the glass, aligning the edges of the glass evenly
with the frame opening. Then add adhesive tape on
both sides of the gap to create clean sealant lines for
the following steps. Tape is to be removed later.
8. Level the glass by pressing down on the edges
carefully.
9. Seal the gap completely with PACTAN
10. Using gloves, run a wet fingure around the gap to
smooth out the PACTAN and wipe up any excess.
11. Examine the silicone carefully and cut out any bubbles.
Fill the gaps again and smooth out the PACTAN again.
12. Wait one hour and remove the adhesive tape
13. Wait 24 hours for the silicone to cure before reinstalling
