Extremely hot / cold surfaces, connections and thermal fluids
BURNS/FREEZING OF LIMBS
Surfaces, connections and tempered thermal fluids can be extremely hot or cold depending on
the operating mode.
Avoid direct contact with surfaces, connections and thermal fluids!
Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety
goggles).
During an active circulation, the thermal fluid circuit is shut off by shut-off valves
MATERIAL DAMAGE TO THE CIRCULATING PUMPS INSTALLED IN THE TEMPERATURE CONTROL UNIT
Do not close the thermal fluid circuit during an active circulation by means of shut-off valves.
Warm the thermal fluid to room temperature before stopping the circulation.
4.2.1
Filling, venting, degassing and draining the bath thermostat
Non-compliance with the safety data sheet for the thermal fluid to be used
INJURIES
Risk of injury to the eyes, skin, respiratory tract.
The safety data sheet for the thermal fluid to be used must be read prior to using it and its
content must be respected.
Observe the local regulations/work instructions.
Wear your personal protective equipment (e.g. temperature-resistant safety gloves, safety
goggles, safety footwear).
Danger of slipping because floor and work area are contaminated. Clean the work station and
follow the instructions for the disposal of thermal fluid and material on page 15 in section
»Proper disposal of resources and consumables«
.
4.2.1.1
Filling and venting the bath thermostat and the externally closed application
PROCEDURE
Check that a hose was installed at the
>Overflow<
[12] (if present). The other end of the hose
must be inserted in a suitable collecting container. Excess thermal fluid will leak at this point
when the temperature control unit is overfilled. Hose and container must be compatible with the
thermal fluid and its temperature.
Lift the
>Bath cover<
[93] from the temperature control unit.
Carefully pour in suitable thermal fluid (see page 28 in the section
) using the filling accessories (funnel and/or beaker). While filling, pay attention to any
necessary measures such as grounding the containers, funnels and other accessories. The ther-
mal fluid can flow via the hose connections to the external application. Follow the instructions
for cleaning the filling accessories on page 15 in the section
»Proper disposal of resources and
.
Switch on the temperature control unit.
Set the setpoint to room temperature (about 20 °C). Additional information is provided on page
34 in section
.
Start the temperature control process by pressing the
>Start/Stop button<
[E].
The filling/venting process is complete when the bath vessel is filled sufficiently and the liquid
level remains constant.
Stop the temperature control process by pressing the
>Start/Stop button<
[E].
Put the
>Bath cover<
[93] back onto the bath opening.
Switch off the temperature control unit.
The volume expansion of the thermal fluid depends on the working temperature range you wish to
work in. Do not go below the minimum bath level/minimal level when working at the “lowest” working
temperature and there should be no overflow from the expansion vessel/temperature control unit
when working at the “highest” working temperature. In case of overfilling, drain the excess amount of
thermal fluid (see page 38 in Section
»Draining the bath thermostat«
). Check if the thermal fluid can be
reused. On page 15 observe Section
»Proper disposal of resources and consumables«
