Explanation of signs:
Danger: This sign is used where there may be injury to person-
nel if a recommendation is not followed accurately or is
disregarded.
Note: Here special attention is drawn to some aspect. May
include reference to danger.

Reference Refers to other information in different sections.
1 Safety information
According to Paragraph 14 of the operational safety decree (BetrSichV)1, the device is a system which
requires supervision. (Classification according to the Pressure Equipment Directive 97/ 23 / EC: Catego-
ry I). Before being put into operation, the system must be subjected to inspection for siting, for ascer-
taining that the device is in order and for correct functioning. A certificate must be issued regarding this
inspection, documenting the extent and the result of the inspection.
1The national regulations of the respective country in which the system is sited must be followed.
1.1 General safety information
A process thermostat is used to heat, cool and circulate heat transfer liquids as specified. Hazards arise
from this due to high or low temperatures, excess pressures, fire and the general hazards due to the
application of electrical energy.
The user is largely protected by the application of the relevant standards.
Further hazard sources can arise from the type of material for which the temperature is to be stabilized,
e.g. by the exceeding or undercutting certain temperature thresholds or by the fracture of the container
and reaction with the heat transfer liquid.
It is not possible to include all possibilities. They remain essentially subject to the judgment and respon-
sibility of the operator.
The devices may only be used as intended, that is as described in this operating manual. This includes
operation by instructed specialist personnel.
The devices are not designed for use in medical applications in accordance with DIN EN 60601-1 or
IEC 601-1.

1.2 Other safety information
Check the device carefully for shipping damage before putting into operation. The device should not
be put into operation if shipping damage has been found.
Only connect equipment to PE grounded mains sockets.
At higher operating temperatures, parts of the device (e.g. connection, drain points) can take on sur-
face temperatures of over 70 °C. Be careful when touching the device Danger of burns.
After a mains failure or after switching off the device, the device surfaces can further heat up briefly.
Use suitable hoses (6.2).
Check the hoses from time to time for any material fatigue. Hot liquid can escape due to hose fracture
and become a danger to personnel and materials.
Heat transfer hoses and other hot parts must not come into contact with the mains cable.
The following actions may start the thermostat unintentionally from the standby mode: Previously ac-
tivated timer mode (7.14), "Start" command via interfaces (8).
Withdraw the mains plug before cleaning, servicing, repairing or moving the thermostat.
Have repairs carried out only by specialists. The device may only be serviced by trained specialist
personnel.
Keep to service and maintenance intervals (9.2.6).
Observe the permissible storage and operating temperatures (11).
The device should not be subjected to fire; otherwise there is the danger of an explosion.
The device may only be operated with its housing in place.
Do not site the device in areas where there are aggressive media.
Only site the device on a level surface.

Integral XT
YAWE0028/ 11/11/2016 Safety information 9
Do not put any heavy parts on the device.
The operating personnel must wear suitable protective equipment.
Do not operate the device when leaks have been found; ventilate the siting room immediately.
With pressure sensitive loads (e.g. glass apparatus) with a maximum permissible operating pressure
below the maximum pressure of the pump (3.5 bars for water, with XT 1850 W 7.0 bars with water),
the hoses of the load must be routed such that kinking or squashing is not possible. In addition, a
separate safety valve must be installed to protect against faulty operation (7.9.4, 7.9.5 and page
34).
When selecting the heat transfer liquid, observe the permissible temperature range.
Heat transfer liquids from LAUDA are recommended which have been tested for use with the device
(6.2).
Always set the over temperature cut-off point immediately according to the heat transfer liquid used
when filling (7.16.1).
If required, the heat transfer liquid should be checked for fitness for use (e.g. when changing the
method of operation), or half-yearly. Further use of the heat transfer liquid is only permissible if the in-
spection indicates this (9.3.1 and 9.3.4).
Keep the cover of the filling point closed during operation.
Under certain operating conditions (degassing, rapid heating phases), the temperature may increase
in the expansion vessel. In extreme cases, the outflow temperature of the device is reached. If heat
transfer liquids are heated beyond a certain temperature (25 °C under the fire point of the heat trans-
fer liquid), then sources of ignition must be kept away from the filling opening and overflow (and at the
aeration point of the expansion tank). In such cases, a nitrogen overlay of the expansion vessel is
recommended (cover XT with connection for nitrogen overlay LWZ 072).
Degas carefully (slowly) (7.6.3).
It is essential to avoid gas cushions in the load system. This can be done by reducing the pump pow-
er by one or two levels and checking that the level indication of the device does not increase.
If an overflow catchments container is connected, it must be suitable (including the connecting hose)
for the maximum operating temperature. The connection hose must be securely fitted.
The overflow must not be closed.
Draining / drain mode is only permissible with an established temperature range (7.7).
During operation the drainage openings must be closed with plugs (standard accessories).
On changing the heat transfer liquid, thoroughly clean the device and completely drain it. It is recom-
mended that the device is rinsed with the new heat transfer liquid (7.8).
It is essential to prevent the ingress of secondary liquids (e.g. via a customer's defective heat ex-
changer).
Only water-cooled devices:
The return hose of the water cooling must be securely fixed on the outlet port in order to prevent the
hose sliding off uncontrollably, also during pressure surges.
The return hose of the water cooling must be fixed on the outlet port that hot cooling water cannot
splash out.
It is essential to prevent kinking or squashing of the return hose for the water cooling. Excessive
pressure can cause the cooling water hoses to tear and hot water to escape.
To prevent damages by a leakage of the cooling water system it’s recommended to use a leak-water
detector with shut-off valve (Aqua Stop).
