1.2 General safety instructions
Read this operating manual carefully. It contains important information about how to handle this device. In
addition to these operating instructions, the operating instructions of the main device Integral XT are also to
be given full consideration. If you have any questions, please contact the LAUDA service department
(chapter 8.2).
Follow all instructions in this operating manual. That is the only way to ensure that you handle the device
correctly.
Ensure that the device is only operated by trained personnel (chapter 2.4).
The device may not be operated without heat transfer liquid.
Use suitable protective equipment when working on the device or connected components.
Use the integrated bypass to ensure that there is a constant flow rate of heat transfer liquid
(chapter 5.2.5).
Never operate the device if:
- Damage has been ascertained on device components or
- the device is leaking.
Switch off the device and unplug the mains plug:
- for service and repair work,
- when moving the device,
- if there is danger.
Do notmake technicalchanges to the device. In the case of infringement, anywarranty claim is void.
Only allow service and repair work to be performed by specialists.
Addition for devices with an additional pump:
The additional pump may not have fluid flowing through it when at a standstill, as this may
damage the pump.
The additional pump, together with the process thermostat from the LAUDA XT series, is a
system requiring monitoring in accordance with §14 of the German Industrial Health and Safety
Ordinance¹. (Classification in accordance with Pressure Equipment Directive 97/23/EC: Category I). Before
commissioning, the system must be subjected to an inspection of the installation, order and functions by
qualified personnel (chapter 2.4) Certification of this inspection shall be created, documenting the scope
and result of the inspections.
¹ The national regulations of the country in which the system is set up must be followed.

2.General
2.1 Description of the device
The flow controller complements the function of the Integral XT process thermostat by receiving the flow of
heat transfer liquid and regulating it by means of a valve. At the pressure output of the flow meter, there is
an internal temperature sensor that allows temperature control at this point or allows the values to be read
out.
In the case of devices with a higher-pressure pump, it is also possible to increase the flow pressure and
thus the flow within the device parameters.
The flow controller is equipped with a bypass as the Integral XT process thermostat requires a minimum
flow rate of 5 L of heat transfer liquid per minute for optimum heating and cooling capacity. If the flow in the
flow meter is lower, the bypass must be opened to ensure that there is a sufficient quantity of heat transfer
liquid flowing back into the Integral XT before flow measurement.
2.2 Intended use
The device is an accessory for the Integral XT process thermostat and has the function of regulating the
flow quantity in the range of 0.2 to 20 L/min. The heat transfer liquid must have a minimum conductivity of
1 µS/cm and be operated within its working temperature range. Silicone oils and mineral oils are not
suitable.
Devices with an additional pump offer the ability to increase the flow pressure.
The device may only be operated in accordance with the intended procedures and under the conditions
specified by these operating instructions and the operating instructions of the Integral XT process
thermostat. Any other type of operation is considered to be unintended can impair the protection provided
by the device.
LAUDA does not accept liability in the case of damage caused by improper use of the device.
2.3 Non-intended use
The device may not be used:
for medical or pharmaceutical applications.
in potentially explosive areas.
with combustible, flammable, highly flammable or explosive heat transfer liquid or silicone oil.
if the permissible working temperature range of the heat transfer liquid is exceeded.
in outdoor installation.
to heat or cool food.

2.4 Personnel qualification
Operating personnel
Operating personnel are personnel who have been instructed by specialist personnel about the intended
use of the device according to the operating manual, about the hazards posed by the heat transfer liquid,
about the working temperature ranges and the pressures within the application as well as the necessary
protective measures.
Specialist personnel
Specific activities on the device must be carried out by technical staff. Technical staff is personnel that can
evaluate functions and risks of the device and the application based on their training, skills and experience.
Typically, this personnel has had appropriate training or third-level education in a relevant technical area.
Specialist personnel must be able to judge the hazard posed by the heat transfer liquid, the working
temperature ranges and the pressures within the application and to determine the necessary protective
measures and the effectiveness thereof.
2.5 Owner's responsibility
The owner is responsible for the qualification of the specialist and operating personnel.
The thermostat may only be configured, installed, maintained and repaired by specialist personnel.
Persons who operate the device must have been instructed in their duties by specialist personnel.
Ensure that specialist personnel and operators have read and understood the operating instructions.
The device is to be used in the intended manner (chapter 2.2).
2.6 EC conformity
The device complies with the applicable basic occupational health and safety
requirements of the Directives listed below:
