Adjusting of the thermostat
The maximum plate temperature of 190 °C /
374 °F
, preset at the factory, must not be exceeded by more
than ± 3 °C / ±
5.4 °F
from 190 °C /
374 °F
. It can therefore only be adjusted with a precision temperature
measuring device (see 1.3.1, Available accessories).
WARNING
All work on the hot-pressing device involving electrical parts has to be carried out
by the respective specialists only.
Observe your local laws about required training of such personnel.
If the measured temperature deviates above the maximum value of 193°C /
379.4°F
or below 187°C /
368.6°F
, the heating control is to be adjusted as follows:
Remove cover screw (8) from adjustment potentiometer (7)
Move adjustment potentiometer of the heating control (7), using an insulated screwdriver, turning it
ever so slightly:
clockwise: temperature will rise,
counterclockwise: temperature will drop.
After 5 minutes measure plate temperature to check as described above.
Proceed carefully and adjust gradually. Observe temperature change.
Re-cover adjustment potentiometer (7) with cover screw (8)
CAUTION
Make sure not to let the temperature rise above 195°C /
383°F
during adjustment.
Excessive temperatures may damage the hot-pressing device or blow the
