Peculiarities of the types RE 212 J, RE 312 J:
1 Description
The thermostats are especially equipped to calibrate glass thermometers or electric thermometers. The
cylindrical (working) chamber can be adjusted in its height up to 20 mm approximately and therefore it is
possible to adjust the surface of the liquid bath within the working chamber higher than the (bath) cover.
Therefore, the total immersing thermometers can be read right at the point of immersion. Additionally the
separate working chamber provides a constant immersion depth, independent from the volume
extension of the bath liquid, an extremely good temperature accuracy and distribution of temperature.
There are pump connectors to connect other external closed circuits, but won’t be available if the
thermostat is used for calibrating.

2 Starting up

Note for electric installation on site:
The devices must be protected with a 16 ampere circuit breaker fitted during
installation.
Exception: Devices with 13 ampere UK plugs.
Firstly, assemble the connecting tube LZM 045 as per diagram (see page 3).
Attention! Do not bend the tube!
Hold up with open-end wrench SW 14mm.
Please move the connecting screws for adjustment of the cylindrical chamber always gradually
(about 2 rotations). Adjust the working chamber as per diagram, and fix it that way it rises 3 mm
above the bath opening. Refill the bath liquid only up to 15 mm underneath the bath opening and only
at working temperature and switched-off pump.
Recommendation for the adjustment of the cylindrical working chamber
Switch the button for the distribution of the pump flow to “ext.” (see diagram Pos. 1).
Position maximum flow rate in the external circuit
(working chamber).
The button will be moved anticlockwise. This
corresponds also to the factory-set up.
3 Maintenance
For cleaning purposes and check-up of the bath liquid, we recommend lifting the front cover with the
chamber as follows: Remove the connecting flange and release the screws M4. This structural
component can now be taken out.
