4. Transport, packaging and storage
4.1 Transport
Check instrument for any damage that may have been caused by
transport. Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property
can occur.
When unloading packed goods upon delivery as well as
during internal transport, proceed carefully and observe
the symbols on the packaging.
With internal transport, observe the instructions in
chapter 4.2 “Packaging and storage”.
If the instrument is transported from a cold into a warm environment,
the formation of condensation may result in instrument malfunction.
Before putting it back into operation, wait for the instrument
temperature and the room temperature to equalise.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during
transport (e.g. change in installation site, sending for repair).
Permissible conditions at the place of storage:
Storage temperature: -20 ... +60 °C
Avoid exposure to the following factors:
Direct sunlight or proximity to hot objects
Mechanical vibration, mechanical shock (putting it down hard)
Soot, vapour, dust and corrosive gases
Potentially explosive environments, ammable atmospheres

12968065.06 06/2019 EN/DE/FR/ES
12 WIKA operating instructions model 55
Store the instrument in its original packaging in a location that fulls
the conditions listed above. If the original packaging is not available,
pack and store the thermometer as described below:
1. Wrap the thermometer in an antistatic plastic lm.
2. Place the thermometer, along with shock-absorbent material, in the
packaging.
3. If stored for a prolonged period of time (more than 30 days), place a
bag, containing a desiccant, inside the packaging.
WARNING!
Before storing the instrument (following operation), remove
any residual media. This is of particular importance if
the medium is hazardous to health, e.g. caustic, toxic,
carcinogenic, radioactive, etc.
The use of liquid damping is always recommended for
temperatures near the dew point (±1 °C around 0 °C).

5. Commissioning, operation
WARNING!
Physical injuries and damage to property and the
environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene,
ammable or toxic substances), harmful media (e.g. corrosive,
toxic, carcinogenic, radioactive), and also with refrigeration
plants and compressors, there is a danger of physical injuries
and damage to property and the environment.
Should a failure occur, aggressive media with extremely
high temperature and under high pressure or vacuum may
be present at the instrument.
For these media, in addition to all standard regulations,
the appropriate existing codes or regulations must also
be followed.
WARNING!
Injuries through hot surfaces or liquids
The sheath also contains a lling liquid; at a temperature
> 250 °C, this liquid may become cloudy or change colour
or, in some cases, may ignite.
For lled instruments, make sure that the medium
temperature is lower than 250 °C.
When screwing the gauges in, the force required for this must not be
applied through the case or terminal box, rather only through the
spanner ats provided for this purpose (using a suitable tool).

When mounting a bimetal thermometer that can be rotated and
swivelled, the specic instructions must be followed. In order to set
the indicator to the desired position, the following steps must be
taken:
1. The lock nut or union nut must be loosened at the process
connection.
2. The hexagon bolts and slotted screws at the swivel joint must be
loosened.
3. Position the indicator as required, tighten the hexagon bolts and
slotted screws, and nally tighten the lock nut or union nut rmly.

5.1 Use of thermowells
CAUTION!
Damage due to incorrect handling
When using thermowells, please ensure that the stem does
not touch the bottom of the thermowell since, due to the
dierent expansion coecients of the materials, the stem
may become buckled at the bottom of the thermowell.
Use the correct insertion length (for the formula for the
calculation of the insertion length, l

5.2 Thermal contact medium
When using thermowells, they must be lled with a thermal contact
medium in order to reduce the heat transfer resistance between
the outer wall of the probe and the inner wall of the thermowell. The
working temperature of the thermal compound is -40 ... +200 °C.
WARNING!
Physical injuries and damage to equipment due to oil
spraying out
When pouring a thermal contact medium into a hot
thermowell, there is a danger of physical injuries and
damage to equipment due to oil spraying out.
Do not ll hot thermowells
6. Faults
CAUTION!
Physical injuries and damage to property and the
environment
If faults cannot be eliminated by means of the listed
measures, the instrument must be taken out of operation
immediately.
Ensure that pressure or signal is no longer present and
protect against accidental commissioning.
Contact the manufacturer.
If a return is needed, please follow the instructions given
in chapter 8.2 “Return”.
