UNPACKING:

Remove the equipment from the packing material and check for damage. Notify the detail of
any damage to your supplier or to Thermoline Scientific without delay.
Retain the packing materi al s until the eq ui pm ent has been thoroughly tested.

Inventory:

• Shelves: 150 litre models = 3 shelves, 235 & 330 litre models = 4 shelves, 500 litre
model = 5 shelves.

• Operating Instructions.

• Electrical mains cable.

USE & FUNCTION:

The Thermoline range of Premium Laboratory Ovens are designed and manufactured in
Australia for all non-critical laboratory and light industrial functions. This range includes seven
models, one which has an optional temperature range up to 300ºC.
Depending on the model selected, either gravity convection (models ending with “G”), for low
capacity drying and conditioning of samples, or fan forced (models ending with “F”), for
increased performance and closer tolerance temperature uniformity.
Models TO-152G, TO-152F, TOH-152G & TOH-152F are suitable for laboratory bench or floor
mounting.
Models TO-235F & TO-330F are suitable only for floor standing.

Features:

• Stainless steel liners (easy clean surface & non corrosive).

• Fibreglass insulation for efficiency.

• Stainless steel sheathed heating element.

• Digital temperature control with over temperature alarm.

• Monitoring port hole.

• Removable chrome plate shelves.

• Exhaust vents for low capacity drying.

LOCATION & INSTALLATION:

LOCATION:

Place the equipment in a well-ventilated area on a firm surface.
Allow sufficient room for the door to open ful l y.
Note that the ovens have a maximum temperature range of 200ºC (300ºC for TOH models),
and as a consequence will have hot surfaces. Do not place the ovens adjacent to heat
sensitive equipment.

1. These ovens are not suitable for use with flammable solvents! They are fitted with
components that may be a source of ignition.

2. This range of ovens is not suitable for stacking!

3. Note that these ovens can be used for low volume drying purposes and will
discharge hot moist air from the exhaust vent.

4. Note: This range of ovens is suitable for low volume drying purposes but should
not be used with large volumes of water since the interior is not sealed. A range
of dehydrating ovens with sealed liners is available for large capacity drying
purposes.

ELECTRICAL:

These ovens are suitable for connection to a standard 240 volt, 50Hz, supply. A dedicated
outlet should be used for the supply, do not use power boards or the like. A 3-pin moulded plug
is fitted as standard to the mains lead. A removable power lead plugs into the IEC socket at the
rear of the oven. Note: The TO-500F oven requires a 15 amp power point!

SPECIFICATIONS:

Electrical: 240 volts, 50 HZ.
Temperature Range: Ambient plus 10ºC to 200ºC. TOH Models Ambient plus 10ºC to 300ºC
Temperature Control Accuracy: +/- 1ºC

PRINCIPLE OF OPERATION

All models feature heavy duty insulation to minimise heat loss, stainless steel interior for
durability, and chrome plate open wire shelves.
The door is fitted with a positive lever action door latch and closes on a silicon gasket. The
exterior is colour bond steel.
The desired operating temperature is set at the temperature controller with digital display of set
temperature and oven temper ature. The heating element is switched by a solid state relay for
reliability.
