Setup
Cleaning
The interior, exterior, and door gasket can be cleaned as often as required using a soft cloth and soapy water. Never use abrasive
cleaners or scouring pads as these will scratch the surface and may result in corrosion. Never use caustic type cleaning agents.
All cabinets have electrical components. Power should be turned off prior to cleaning. These items should not be subjected to any
levels of moisture.
Door Gasket
The door gasket should be cleaned regularly with a mild soap
solution. If a gasket is to be replaced, please contact
Thermoline Scientic. Regular inspection is recommended.

Start Up Procedure Laboratory Oven User Manual By Thermoline Scientific
Start Up Procedure
Start Up process:
• Before proceeding, please make sure that all internal
and external packaging has been removed from the
appliance and that all tape, plastic bags and foam
pieces have been removed.
• Take the supplied lead and plug it into the male IEC
socket on the side of the oven. Next, plug the 3 pin
plug into a 10amp General Purpose Outlet.
• Turn the main switch adjacent to the temperature
control to 'ON' to start the oven.
• The controller will go through a warm up period where
all segments of the display will be on, before indicating
the set temperature (SV) on the lower display and oven
actual temperature (PV) on the top display.
17

Start Up Procedure
Loading
Laboratory ovens require constant air ow throughout the
cabinet to maintain the desired temperature. Correct loading of
the shelves must be considered for ecient cabinet
performance.
Loading Requirements:
• Distribute the load evenly over all the shelves rather
than stacking everything on one shelf. This is to
ensure unobstructed airow throughout the chamber.
• Ensure the highlighted area of the cabinet is clear of
all obstructions to ensure that proper ventilation is
allowed throughout the cabinet. (Fig 1 & 2.)
• Never block off air vents in the rear panel (applicable
only to the TOH-150F).
• Do not load samples on the oor of the laboratory
oven.
Fig 1.
Fig 2.
In the case of the TO-30G and TO-150G, the element is below a grill at the bottom of the cabinet and
loading there would be a safety issue.

Sensor Calibration
There are a number of factors that will affect the accuracy of
the temperature displayed in relation to the actual temperature
inside the Oven. These could include the following:
• Sample load inside the cabinet (the load should be
distributed evenly).
• Product temperature (at higher temperatures the heat
loss from the product will be greater).
• Location of the sensor (the temperature sensor can
never be placed in the centre of the oven because it
could be damage.
The Omron temperature control has a parameter that can
correct the temperature displayed. This sensor correction
parameter is displayed as “ iNS “ (Input Shift).
In simple terms, this parameter adds or subtracts a correction
value to the displayed temperature to make it read the correct
temperature.
The calibration sensor can be axed to the centre of the
middle shelf.
Once the oven has stabilised, any difference in the temperature
reading can be offset using the sensor correction parameter.
The calibration parameter can be accessed as follows:
How to
Press PAGE to display sensor correction parameter.
Use the UP or DOWN button to adjust the sensor correction.
After this, allow the digit to stop ashing and the screen will
display the adjusted value.
