4.1.5 Setting the setpoint
PROCEDURE

Switch on the temperature control unit.

Press and hold the
>SET key<
[D]. The setpoint is displayed.

Use the
>Arrow keys<
[C] to select the required value.
(up) the temperature value is increased, (down) the temperature value is decreased.

Release the
>SET key<
[D]. The new setpoint is set.
4.2 Filling, venting and draining
Observe the wiring diagram. → From page 59, section »Annex« .
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 and venting externally closed application
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 workplace; ob-
serve the proper disposal of thermal fluid and aids. → Page 15, section »Proper disposal of re-
sources and consumables« .
Semi-automatic venting
DAMAGE TO THE TEMPERATURE CONTROL UNIT

An elevated tolerance time for the pressure drop can damage the pump if the thermal fluid
level in the system is also too low.

Constantly observe the thermal fluid level on the
>Sight glass<
[23] or the
>Level indicator and
drain< [38]. Fill up the thermal fluid during the venting phase so the thermal fluid level does
not fall below the minimum mark in the >Sight glass< [23] or the >Level indicator and drain<
[38].
Calculate whether the capacity of the
>Expansion vessel< [18] can absorb the expansion volume
during operation. Assume the following volumes for this calculation: [Minimum filling capacity of
the temperature control unit] + [Volume of the thermal fluid hoses] + [Jacket volume of your appli-
cation] + [10% / 100 K].
▪ During the fill process, ensure any necessary measures, such as earthing the tanks, funnels and
other aids, have been taken.
▪ Fill to the lowest possible height.
