Assembly as cooling thermostat
Notice
Falling / toppling equipment
Property damage

Do not tilt the cooling device during transport and never turn
it upside down.
-
After transport, site the device in place where possible two hours
before putting it into operation so that, if necessary, oil deposits
can form again and the compressor can develop its maximum pow-
er.
-
Do not cover the ventilation openings.
-
Keep a distance of at least 40 cm free on all sides of the device.
-
Set the flow distribution to INT so that during operation as a bath
thermostat (without external consumer) the flow is discharged
from the opening for the internal bath circulation.
-
Plug the appliance connector of the cooling underpart into the ap-
propriate socket 51H and the control cable into the connection
socket at the back of the operating panel.
-
During operation as a bath thermostat without an external con-
sumer and with the pump connection set fitted, the outflow nozzle
of the pump connection set must be closed (use sealing plug) or
connected to the return nozzle with a hose.
-
For bath temperatures above 70 °C attach the sticker included in
the supplied items to an easily visible point on the bath.
.
-
Operation with external consumer (

Device description of the calibration thermostat
RE J 1225 G
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 im-
mersion 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.
