2-2 Shake 'n Stack
The two switches found on the control panel operate the power and the
rotisserie drive. The power switch is marked with a "1" and a "0". By
switching to the "1" position, the mains power is connected to the oven
and the green section of the switch is exposed to indicate that the oven is
"ON". The switch to the right operates the rotisserie/shaker. The
rotisserie/ shaker switch cannot be operated without first turning on the
power switch. To the left of the rotisserie/ shaker switch is a dial to adjust
the rotisserie speed from 5-15 rpm and the shaker speed from 4-10 rpm.
Instructions to set up the shaking platform are in Section 4.
The temperature controller has 4 buttons along the lower edge of the
controller.
When the power is switched on, the display shows three dashes (---) as the
controller goes through its internal self-tests, which are completed within 5
seconds. The display then shows the compensated temperature of the oven.
Figure 2-1. Temp Controller
To set the controller temperature, press and release the L1 button. The L1
LED will blink on-and-off, and the display will show 1SP for 1 second,
then the present setpoint value. Press the up or down arrow button to
change the desired setpoint within the oven operating range of 35°C to
85 °C. Press the Enter button ( ) to store the new setpoint value, or press
the X button to return to normal mode without saving the new setpoint
value.
The warm up time for the oven varies according to the load and the
ambient temperature. When first switching on the oven (no bottles
installed), allow approximately one hour for the temperature to stabilise.
Solutions should be pre-warmed to the required temperature to minimise
sample stabilisation time.
