Holding capacity: 1.8 l
Nominal supply voltages: 230V AC
50 - 60 Hz
Nominal capacity (heating): 150 VA
Temperature setting range: 45 - 65 °C ±3 K
Excess temperature switch-off
mechanism: at 85 °C ±5 K
3.6.4 Wax bath If the actual temperature rises above the range of
normal working temperature, an excess tempera-
ture switch-off mechanism responds. The wax
bath heating is disconnected. The yellow signal
lamp is extinguished. Use of the wax bath can be
resumed only after a cooling down period. For
cooling down, disconnect the wax bath connector
plug from the socket at the rear of the instrument,
or switch off the main switch.
The wax baths are equipped with heating. While
the heating is functioning, the yellow pilot lamp
lights (1).
The handle (2) is insulated. The outside wall
(3) is likewise thermally insulated. However, it
becomes hot to the touch in heating operation.
Despite this, burn hazard exists when touching it.
The inside of the interior container (4) is coated
with Teflon. The interior container gets very hot.
It has minimum and maximum level indicator
marks (5).
Caution! The interior container (4) of
the wax bath becomes very hot when
the heating function is activated! Do
not touch the gray upper rim of the con-
tainers with your hands! Risk of injury!
If the excess temperature switch-off
mechanism reacts several times, call
Technical Service without delay. DO
NOT continue to use the wax bath.
Empty the wax baths completely be-
fore the paraffin cools! When cooling
down, the paraffin contracts, which
can cause damage to the wax bath.
