There are variations in bun products Worldwide that are
used on the A.J Antunes HEBT toaster such as mois-
ture content, bun formulations, age, tolerances etc. The
HEBT was designed to compensate for bun variations
by allowing user to adjust the compression, light/dark
(speed) & temperatures settings in order to achieve a
Gold Standard toasted product.
1.LIGHT DARK ADJUSTMENT: Adjust the light dark
setting with the ▲or ▼buttons. The default light/
dark setting on the HEBT from the factory is 0 but can
be adjusted from Lighter 0-10 to Darker 0-10 Light
10 is the lightest setting and dark 10 is the darkest.
Each increase in “lighter” value will decrease the pass
through time and each increase in “darker” value with
increase the pass through time.
2.TEMPERATURE ADJUSTMENT: Adjust the set point
temperature on the platens in the program menu. The
default temperature settings on the HEBT are A Platen:
271°C (520°F) and B Platen: 271°C (520° F) . The tem-
peratures can be increased to +/- 50°F (10°C) if needed
to achieve an acceptable toast quality.
3.COMPRESSION ADJUSTMENT: Adjust the compres-
sion knob on the left side of the unit. The default com-
pression setting on the HEBT is 4 but is adjustable from
1-7. It is acceptable to adjust the compression from 1-7
as needed to achieve the desired toast quality and bun
compression.
