Using the equipment
5.2.1 Setting the control temperature
The temperature of the circulation liquid is set using the
S
button on the heating
circulator.
1. Whilst the display is showing the bath temperature, press the
S
button. This will
cause the display to flash indicating that it can be set.
2. Use the main dial
to set the desired temperature.
If no key is pressed for 10 seconds, then the display will revert back to showing the
bath temperature and the set temperature will remain at its original value.
3. Press the
S
button to store the requested value and the display will revert to showing
the bath temperature.
If the temperature selected is higher than the current liquid temperature, the heater
light will come on.
5.2.2 Selecting liquid type
The type of liquid selected limits the temperature range available for safe operation of the
equipment. It is important the liquid selected matches the actual liquid in the tank.
It is the user organisation
’s responsibility to assess the risks associated with the choice
of heat transfer liquid chosen and to put in place safe working practises and appropriate
protective equipment for personnel when considered necessary.
1. Press the
F
button four times
– the display will show the current liquid type.
2. Use the main dial to select the required liquid.
Liquid
Set temperature range
5°C to 100°C
0°C to 100°C
-20° to 50°C
* LtL = low temperature liquid, for example 50% water/50% glycol
3. Press the
S
button to set the liquid type and return to normal temperature display.
4. Change the Over Temperature thermostat to be approximately 5
°
C above the new
working set point temperature. See section 5.1.3
To ensure protection the over-temperature cut-out must be set appropriately
for the heat transfer liquid selected.
When changing the liquid from water to oil, ensure all residue of water is
removed from the pump and hoses. There is a risk of scalding from boiling
water.
5.2.3 Configuring a preset temperature
The equipment can be configured with three temperature presets to allow it to be
conveniently run at frequently used temperatures. The method below is used to
configure preset 1; the other presets can be set in a similar manner.
