Turn on the instrument by pressing the button ON / OFF. Button and the display will light up.
The display shows the initialization sequence and then the instrument is ready for use.
NOTE: every time you turn the instrument beeps intermittently, the icon of visual alarm and the
word “end” appear on the display, indicating that a heating cycle had been done before. Press any
button to silence the audible signal and the icon appears.
5.2 Turn on/off of the circulation pump (if present)
If installed, the circulation pump can be switched on or off at any time using the button "Pump".
The pump can be operated only if the instrument is switched on, when the "Power" button is in the
ON position.
NOTE: in the first use or after emptying of the tank of the water bath is possible that the pump has
at its internal air bubble and therefore functions "vacuum". If during this stage you hear a sucking
sound abnormal aspiration, immediately turn off the pump and bring the water level above the
nozzle outlet of the heat pump (see paragraph 3.2).
5.3 Setting of parameters
5.3.1 Working temperature
When the instrument is switched on, pressing one time the SET/PROG button, the set
temperature value starts to blink.
Set the desired temperature value (in Celsius degrees) pressing keys.
It’s possible a quick movement between the digits using the SHIFT button.
Confirm the set value with another press of SET/PROG button.
5.3.2 Working time
After confirming the temperature, the last value of the set time (timer) starts flashing.
Set the desired value (hh:mm) by pressing keys. It’s possible a quick movement between the
digits using the SHIFT button.
Confirm the set value with another press of SET/PROG button.
NOTE: the value “00:00” indicates the operating mode "continuous", that means once you start
the operating cycle by the START / STOP button, it continues maintaining the set temperature
until it is stopped manually (START/STOP ).
If you set a value of time, such as 1 hour, the instrument will reach the set temperature and will
maintain it for an hour.

5.4 Start/stop heating cycle
After setting the operating parameters, pressing START / STOP button with long press (4-5
seconds), the heating cycle starts for the defined time in hh:mm or continuous (00:00). The word
“end” at the top right corner of display disappears, the message RUN appears in the bottom left
corner and display shows contemporary: timer, temperature measured inside the tank and set
temperature (see Picture 3).
At any time you can always manually stop the cycle by pressing the START / STOP button.
Once the set time or after manual stop, the instrument beeps intermittently, the icon of visual alarm
and the word "end" appear on the display. Pressing any button it’s possible to silence the
audible signal and the icon appears.
NOTE: the acoustic signal will not end until it is stopped by the operator, but the heating cycle is
terminated so for the samples inside the instrument will remain exposed to the internal temperature
of the tank.
5.5 Functions with password access
5.5.1 Access to menu with password

Set the desired delay value (hh:mm) pressing keys. It’s possible a quick movement between
the digits using the SHIFT button. Confirm the set value with another press of SET/PROG
button.
The display comes back to the standby screen (see Picture 3).
Pressing the START/STOP button with long press (4-5 seconds) the instrument starts the
work cycle but it doesn’t immediately heat: the word “end” and the set delay time alternately blink
on the top right part of display, counting the wait time until the real starting of heating.
Once the delayed time is passed the instrument starts to heat and the regular timer appears on
display.
5.5.3 Safety temperature limiter for samples protection
The instrument has the possibility to limit the maximum work temperature for the samples
protection from an erroneous setting of the working temperature.
Please follow the instructions reported at paragraph 5.5.1 and using the keys set the “0003”
password. It’s possible a quick movement between the digits using the SHIFT button.
Confirm the set value with another press of SET/PROG button.
On the top right part of display the parameter “tm” (temperature max) and the maximum expected
value for the kind of instrument appear.
Set the maximum temperature value you want the instrument doesn’t exceed during work cycle by
the keys. It’s possible a quick movement between the digits using the SHIFT button.
Confirm the set value with another press of SET/PROG button.
Example
If the set temperature for the work cycle is 100 °C and the safety temperature is fixed at 70°C, the
instrument tries to achieve the set temperature (100°C), even if it’s major than the safety
temperature set in this menu (tm).
When the 70 degrees are achieved the instrument goes in alarm emitting an audible intermittent
alarm (silence it pressing any keys) and the heating element doesn’t receive power supply until to
the temperature will go below the safety temperature (tm).
NOTE: the instrument tries in any moment to achieve the set work temperature; as a consequence,
until it is bigger than the safety temperature (tm), it goes in over temperature alarm as described in
the previous paragraph.

keys. Confirm pressing shortly SET/PROG .
5.5.5 Temperature range for over temperature alarm
The instrument has the opportunity to set the range of temperature over which it goes in over
temperature alarm.
NOTE: even if this value is adjustable by the operator, it’s already set by factory and perfectly
calibrated in function of instrument type, natural/forced air oven, incubator or water bath.
We recommend to do not change this value unless absolutely necessary, because temperature
fluctuations more or less than the set one, especially in models with natural convection, are normal
and thus reducing dramatically the value of AL, it would risk do go frequently and unnecessarily
alarmed the instrument.
Please follow the instructions reported at paragraph 5.5.1 and using the keys set the “0003”
password. It’s possible a quick movement between the digits using the SHIFT button.
Confirm the set value with another press of SET/PROG button
On the top right part of display the parameter “tm” (temperature max), pass to the next parameters
pressing shortly SET/PROG more times.
Find the parameter AL (alarm), set the minimum temperature value above which you want the
instrument goes in alarm pressing the keys. It’s possible a quick movement between the
digits using the SHIFT button. Confirm the set value with another press of SET/PROG
button.

5.5.6 Temperature offset on single point, on entire ramp, on room temperature
sensor
The instrument has the opportunity to set the offset value on a single temperature point, on the
entire temperature ramp and on the room temperature sensor.
NOTE: even if these values are adjustable by the operator, they are already set by factory and
perfectly calibrated with certified and referable Accredia measurement instruments.
We recommend that you do not change these values unless absolutely necessary, for example if
after a check with digital certified thermometer you find a discrepancies between the reading of the
instrument and the external thermometer.
Please follow the instructions reported at paragraph 5.5.1 and using the keys set the “0003”
password. It’s possible a quick movement between the digits using the SHIFT button.
Confirm the set value with another press of SET/PROG button
On the top right part of display the parameter “tm” (temperature max), pass to the next parameters
pressing shortly SET/PROG more times.
PARAMETER
DESCRIPTION
Pb
Changing this parameter you can correct the reading of PT100 sensor inside the
instrument on one point temperature. The correction will therefore be attributable
to one specific point.
PK
Changing this parameter you can correct the reading PT100 sensor inside the
instrument over the entire temperature ramp, that is going to change the
inclination of the ramp reading of the sensor.
PA
Changing this parameter you can correct the reading of environmental PT100
sensor installed on the instrument (only refrigerated versions) on only one
temperature point. The correction will therefore be attributable to one specific
point.
6 Emptying of the tank
ATTENTION!
When you want to empty the tank of the water bath is essential that
the heating element is no longer powered and was first cooled down.
For this reason it is necessary, therefore, before emptying the water bath to stop the cycle of
heating and wait until the water has cooled.:
ATTENTION!
Before proceeding with the removal of water wait until it has
sufficiently cooled!!!
Once cooled, it’s possible to emptying with help of a tank and / or absorbent cloth or paper.
For the instruments with circulation pump, it’s possible to proceed as indicated below.

6.1 Use of the emptying kit (if present pump)
If the instrument is equipped with circulation pump is able to use for the emptying of the water bath
together with a kit of emptying rubber provided with the instrument
The water bath can be emptied using the above kit as follows:
1. Wait for the cooling of the water;
2. Turn off the circulation pump by the switch “Pump”;
3. Using to the special double cone white, connect the short tube to the suction nozzle of
the pump at the bottom of the tank (see Picture 4);
4. Connect the long tube to the output nozzle in the top of the tank. Put the other terminal
of the tube in a recipient of a sufficient capacity (see Picture 4);
5. Switch on the pump through the button ON/OFF “Pump” to start the emptying: in this
way the pump transfer the water from the tank into the external recipient;
6. Using the shorter tube take away the remaining water on the bottom of the tank and
once the pump start to work at vacuum switch it off immediately;
7. If necessary remove the last traces of water with an absorbent cloth or paper.
ATTENTION!
The pump musn’t be use at vacuum, but only for the circulation of
water, bacause it is designed to pump liquids and not air.

7 Clean and maintenance
Proper maintenance and cleaning of the instrument guarantee its good conditions.
The tank of the instrument is made of stainless steel, so it can be cleaned with any detergent
provided it is not aggressive and / or corrosive.
You should clean the inside and outside surfaces with a standard all-purpose cleaner sprayed on a
soft cloth.
Before proceeding with any cleaning or decontamination, the user must ensure that the method
used does not damage the instrument.
ATTENTION!
In case of use of absorbent paper, take particular care to avoid that
traces of it remain inside the tank.
Eventually pieces of paper can gravely damage the pump.
IMPORTANT:
If the instrument must be returned for service, it is necessary to provide for proper cleaning and
possible decontamination by pathogens of the same.
