Safety
The following symbols mean:-
Caution: Read these operating instructions fully before use and pay particular attention to
sections containing this symbol
Caution: Surfaces can become hot during use.
Always observe the following safety precautions
Use only as specified by the operating instructions, or the intrinsic protection may be impaired.
After transport or storage in humid conditions, dry out the unit before connecting it to the
supply voltage.
Connect only to a power supply with a voltage corresponding to that on the serial number
label.
Connect only to a power supply which provides a safety earth (ground) terminal.
Ensure that the mains switch and isolating device (power supply connector) are easily accessible
during use.
Before moving, disconnect at the power supply socket.
Do not check the temperature by touch, use the temperature display or a thermometer.
To reduce the risk of eye injury during high temperature operation, use safety goggles or
spectacles.
Do not touch surfaces which become hot during high temperature operation.
Ensure that the operating temperature is less than the maximum operating temperature of
your sample material.
Set the adjustable overtemperature cut-out after setting or changing the working temperature,
and reset it at monthly intervals to check that the cut-out is operating correctly.
Do not block or restrict ventilation slots.
If liquid is spilt inside the unit, disconnect it from the power supply and have it checked by a
competent person.
It is the user‟s responsibility to carry out appropriate decontamination if hazardous material is
spilt on or inside the equipment.
Do not connect to a power supply or switch on before filling the tank.
Take care when topping up or draining, as the liquid in the tank may be very hot or cold.
If the alarm lamp is illuminated do not touch the liquid or the heater, they may be very hot.
Refill carefully, a hot heater can cause a spattering of very hot water droplets and scalding
steam.
Do not place removable control units on a flammable surface.
Always use a lid or polypropylene spheres when operating above 60°C. Take care when
raising and removing the lid, it may be hot. Steam and hot vapours can cause scalding.
Drain before moving the bath. Before draining allow the liquid to cool to below 50°C or heat to
above 10°C.
Use only liquids specified in the operating instructions, within the specified temperature range.
If the alarm lamp is illuminated the liquid temperature may be above its recommended
maximum: do not inhale the vapours given off as they may be toxic; liquids should be safely
discarded and replaced.
When pumping to external apparatus, always use connecting pipe or hose suitable for the
operating temperature and liquid used, and check that the pipe connections are secure.
Do not disconnect any pipes or hoses while they contain very hot or cold liquid.
For indoor use only. Do not use outdoors
