3 Product description
This chapter contains an overview of the design and function of the product.
3.1 Function description and design
The combi well is a mounting well with additional measurement resistor for
oil pointer thermometers and is used for the remote transmission of mea-
sured temperature values. Depending on the device type, the electrical tem-
perature measurement can be transmitted remotely as follows:
–Combi well (standard): Connection via the integrated Pt100 measurement
resistor
–Combi TT: Connection via an analog 4...20mA output

Product description . 8122419/01 EN16
The terminal connections for the evaluation devices as well as a cable gland
for the immersion pipe for the temperature sensor of the pointer thermome-
ter are located in the connection head. The combi well can be combined with
various pointer thermometers and evaluation instruments. Read the operat-
ing instructions for these.

Packaging, transport and storage . 8122419/01 EN18
4 Packaging, transport and storage
4.1 Purpose
The packaging is designed to protect the packaged product during transport,
loading, unloading and during periods of storage in such a way that no detri-
mental changes occur. The packaging must protect the goods against per-
mitted transport stresses such as vibration, knocks and moisture (rain, snow,
condensation).
The packaging also prevents the packaged goods from moving impermissibly
within the packaging.
4.2 Suitability, structure and production
The goods are packaged in a sturdy cardboard box or solid wooden crate.
These ensure that the shipment is secure when in the intended transporta-
tion position and that none of its parts touch the loading surface of the
means of transport or touch the ground after unloading.
Inlays inside the box or crate stabilize the goods, preventing impermissible
changes of position and protecting them from vibration.

8122419/01 EN . Packaging, transport and storage 19
4.3 Markings
The packaging bears a signature with instructions for safe transport and cor-
rect storage. The following symbols apply to the shipment of non-hazardous
goods. Adherence to these symbols is mandatory.

4.4 Transportation, receipt and handling of shipments
In addition to vibrations, jolts must also be expected during transportation.
To prevent possible damage, avoid dropping, tipping, knocking over and col-
liding with the product.
If the packaging tips over or falls, damage is to be expected regardless of the
weight.
Every delivered shipment must be checked for the following by the recipient
before acceptance (acknowledgment of receipt):
–Completeness based on the delivery slip
–External damage of any type.
The checks must take place after unloading when the cartons or transport
container can be accessed from all sides.

Packaging, transport and storage . 8122419/01 EN20
Visible damage
If external transport damage is found upon receipt of the shipment, proceed
as follows:
–Immediately record the transport damage found in the shipping docu-
ments and have this countersigned by the carrier.
–In the event of severe damage, total loss or high damage costs, immedi-
ately notify the sales department at Maschinenfabrik Reinhausen GmbH
and the relevant insurance company.
–After identifying damage, do not modify the condition of the shipment fur-
ther and retain the packaging material until an inspection decision has
been made by the transport company or the insurance company.
–Record the details of the damage immediately on site together with the
carrier involved. This is essential for any claim for damages.
–If possible, photograph damage to packaging and packaged goods. This
also applies to signs of corrosion on the packaged goods due to moisture
inside the packaging (rain, snow, condensation).
–Be absolutely sure to also check the sealed packaging.
Hidden damage
When damage is not determined until unpacking after receipt of the ship-
ment (hidden damage), proceed as follows:
–Make the party responsible for the damage liable as soon as possible by
telephone and in writing, and prepare a damage report.
–Observe the time periods applicable to such actions in the respective
country. Inquire about these in good time.
With hidden damage, it is very hard to make the transportation company (or
other responsible party) liable. Any insurance claims for such damage can
only be successful if relevant provisions are expressly included in the insur-
ance terms and conditions.
