OPERATION – Program Mode
In program mode the oven will cycle automatically through a series of up to eight
steps. Each step will consist of a temperature, a ramp, and a time. The oven wil
warm up over the ramp time and then be held at the step temperature for the step
time before moving on to the next step. Once the last step has been completed the
oven will switch off. The step time will only begin once the oven has reached the step
temperature.
3.29 Position the shelves within the work chamber.
3.30 Switch ‘ON’ the mains switch, indicated by lighting up green.
3.31 If the unit is already in use press the ‘start/stop button ’ to extinguish the amber lamp.
3.32 Press and hold the ‘program button ’ for 2 seconds, the ‘setpoint display’ will change to
show the temperature for the first step. The temperature display will show “S 1” to indicate
that the setpoint for step one is being adjusted.
3.33 Use the increment and decrement buttons to set the desired temperature.
3.34 Press the ‘start/stop ’ button to move on and set the ramp for step one.
3.35 The ‘setpoint display’ will show the ramp time in minutes, the ‘temperature display’ will show
‘r 1’ to indicate the ramp for step one is being adjusted.
3.36 Use the increment and decrement buttons to set the desired ramp rate. A ramp of
rate of zero indicates the oven should heat up as quickly as possible.
3.37 Press the ‘temperature button ’ to enable hold-back. The ‘temperature display’ will
change to ‘rh1’ to indicate hold-back is enabled for step one.
3.38 If hold-back is enabled the ramping up of the oven temperature will be paused if actual

4. MAINTENANCE
ROUTINE CHECKS ON EACH OCCASION OF USE
4.1 Check the condition of supply lead and plug top. These should be sound and undamaged.
4.2 Connect to mains supply and check:-
Supply switch operation.
Green Supply indicator is working.
Check at working temperature, that the heat indicator (This can be seen in the bottom
display far right hand side) cycle’s on and off without the overheat (red LED) illuminating.
A temperature check can be done by using a suitable temperature probe, inserted through
the rear vent and connected to a calibrated digital meter.
5. PREVENTATIVE MAINTENANCE
Ensure that the unit is maintained in a clean, dry condition and when not in use, stored in a normal
warm atmosphere.
Minimum recommendation every six months:-
5.1 Check the plug top connections are tight and the fuse rating is correct.
5.2 Check the operation of the overheat protection system by raising the desired temperature
above the overheat temperature.
5.3 Carry out an electrical safety check (Portable Appliances) using an appropriate appliance
tester operated by a competent person.
5.4 Check that the control temperature is maintained within limits.
The manufacturer can offer the above service on request.
6. SAFETY
When the unit is to be used for the incubation of microbiological specimens, please consider
carefully the siting and use of the unit to ensure safe operating conditions for all users.
Appropriate safety precautions are essential for any microbiological work and any guidelines
issued (for example, The Department of Education and Science guidelines) on this subject
must be followed exactly. They are necessary to protect both people and animals from
infection and to protect cultures of micro-organisms from infection by unwanted
contaminants.
If liquids contained in partially sealed vessels are to be heated in the unit, then at all times
the temperature setting must be such that no appreciable pressure build-up is allowed to
occur within the vessel. The risk of explosion becomes high if the temperature setting is
higher than that of the boiling point of the liquid. Therefore, any vessels that require heating
SHOULD NOT be completely sealed. These units are not suitable for use where
inflammable solvents are being used where the solvent concentration can reach inflammable
or explosive levels.

7. GENERAL
 Mop up any spilled liquid from the floor of the unit.
 Do not place samples on the chamber floor.
 Take the normal precautions not to allow water to come into contact with the electrical
components.
 The outer surfaces can be cleaned with a warm, damp, soapy cloth or any proprietary
cleaner suitable for a painted surface (do not use solvents or harsh abrasives).
 The work chamber may also be cleaned as above.
