OPERATION:
(Con’t)
AC POWER LOSS:
The operating microprocessor possesses a non-volatile memory. Upon
resumption or recovery from an AC power loss, the following will be noted:
?
All readouts will flash until any key is pressed.
?
If unit was shaking at the time of power failure, it will resume operation at
the speed and timer settings that were entered at the time that AC power
failed.
?
In the event of a speed sensor problem, the speed readout will display
EEE
and shaking will stop. The unit must be disconnected from power
source for a minimum of 3 seconds before being reset. If the problem
persists, contact local Lab-Line dealer for assistance.
USING THE OPTIONAL COOLING COIL:
?
Adjust the temperature to the desired temperature.
?
Connect the coolant hoses to the cooling coil fittings on the back of the
unit. Start the coolant flowing through the cooling coil; flow rate should be
at least 6-8 liters per minute. The coolant temperature must be at least
15ºC less than the desired chamber temperature. The coolant flow and
temperature must be constant.
?
Allow the chamber temperature to stabilize at the setpoint.
?
Readjust the safety thermostat per instructions on previous page OP-2 at
“Temperature Control Module."
?
Lift the cover and load platform. Close lid.
USING THE OPTIONAL GASSING MANIFOLD:
The gassing manifold allows the operator to inject an inert gas into the
sample vessel(s) while temperature control and shaking continue. Put the ¼" ID
tubing from the gassing manifold inlets in the vessels. If more than 8 vessels are
used, manifold connectors and additional tubing will accommodate the full
number of vessels.
