4.2 Using the Fan Controller
1
Attach the fan connector to the back of the tempera-
ture control box.
2
Attach the heat sensor cable into the remaining
socket on the rear of the temperature control box.
3
Select the temperature you require to run the gel at,
noting that while the control unit is factory calibrated
there will be a temperature gradient across both the
glass and aluminum plate. Therefore, it is necessary
to set a temperature on the dial approximately 10 °C
lower than required at the gel plate, e.g. if you require
to run the gel at 55 °C set the dial to approximately
45 °C. Attach the mains lead to the control unit and
turn on the power. The light on the control panel indi-
cates when the contacts are made for the fan opera-
tion. When the light is on the fan will be off. When
the fan cuts in the light will go out.
4
The fan will automatically switch on/off to maintain
the gel temperature at +/– 4 °C of the set temperature.
After monitoring the gel temperature increase the dial
setting as necessary. A temperature indicator strip on
the center of your glass plate will allow you to confirm
that your dial setting is correct.
