SAFETY EXPERIMENT PROTECTOR - HT RANGE ONLY
To set the safety device:
1. Safety device knob (located on the rear) is turned fully clockwise.
2. Set the temperature on the temperature controller at which temperature
you require the device to operate, using instructions for set point 1 (see
page 6). Allow the liquid to reach this temperature and settle.
3. Slowly turn the knob back anticlockwise until it clicks.
4. Adjust the temperature on the temperature controller to the actual
required operating temperature - value less than set in 2 above.
When in alarm condition heater is switched off and the motor remains on.
LOW LIQUID LEVEL FLOAT SWITCH - ALL MODELS - “FiLL” MESSAGE DISPLAYED
The bath features a low liquid level alarm - the display will show “FiLL” in this condition. Heating will be
switched off if the liquid level falls below the recommended level. The stirring action will continue. To
reset the Low liquid level warning - top up liquid level
Use caution when refilling the tank as hot elements can spit and create
scalding steam.
PERIODICAL CHECK
The low liquid level float switch should be checked periodically by lowering the level of liquid in the tank
and a “FiLL” message should appear. In the event that this does not occur please contact our service
department. The Safety Experiement Protector featured on the NE4-HT should be routinely checked for
correct operation where used. Follow set up instructions as described above.
