Labnet 311DS Environmental Shaking Incubator (I5311-DS and I-5311-DS-230V) - Manual (Page 6)

OPERATING THE LABNET I-5311-DS INCUBATOR SHAKER
As advised in the installation section, it is very important that the unit be level and placed on a
very solid surface. When loading the platforms, it is also important to load these in a balanced
manner or the unit can vibrate and possibly walk. Shaking unbalanced loads for extensive
periods may also damage the shaker.
Before powering up the unit, you should first set the mechanical Safety Thermostat on the back
of the unit to a temperature just above your intended operating temperature or at max (setting
of 10) this safety is not needed.
After you first power up the unit you should notice the shaker display first showing dashes then
the power input line frequency (F60 or F50 for 60 Hz or 50Hz) and the temperature controller
display showing some random numbers and dots blinking.
The shaker display and temperature display should then settle down with the shaker display
showing the last time that was set (or HLd) for continuous operation, and the temperature
display showing the chamber temperature.
You may now set the desired operating temperature, the desired shaking speed and the
desired shaking time (see Controls section of this manual). It is recommended that you test all
loads to be shaken a slow speed under observation and then gradually raise the speed to
insure the load and unit are stable. The unit should also be allowed to equilibrate to the set
temperature before using.
Once the temperature, shaking speed and shaking time are set, use the Stop / Start pad to
initiate shaking. When shaking in the timed mode, the word End will be displayed on the
shaker display when the shaking is done. In timed mode the word Hld (hold) will be displayed
on the shaker display. The user may switch the shaker display to show the shaking speed by
pressing the “Push to Shift” knob.
The user can observe the load being shaken through the glass window and can also turn on
the chamber light for additional visibility. The chamber light should not be left on for an
extended period as it adds heat to the chamber and may cause the chamber tempera-
ture to rise above the set point.
The user may open the chamber door at any time to gain access the chamber. If the shaker is
running when the door is open, the shaker power will be immediately cut causing the shaker to
slow and stop. The shaker display will show Opn for open. Shaking will automatically resume
when the door is closed if there is still time remaining on the shaker run. Note: The clock
continues to count down when the door is open even though the shaker has stopped.
CARE & MAINTENANCE
No routine maintenance is requires for the electrical or mechanical components of the unit. The
incubator exterior, interior and shaking platform should be wiped down periodically with a soft
damp cloth with mild soap. Do not use chlorine-based bleach or abrasives. Any spills in the
incubator and/or on the shaking platforms should be cleaned up immediately. Be sure to
disconnect the power cord before cleaning or decontaminating the oven.
