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.
4.3.1
Filling and venting externally open 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.

The >Bypass valve< [62] (if any) is not adapted to the external application
MATERIAL DAMAGE TO THE EXTERNAL APPLICATION
A closed
>Bypass valve<
[62] can cause the pressure in the thermal fluid circuit to become too
high for the external application used. It may cause the thermal fluid to overflow in the exter-
nal application and/or damage the external application.
Initial filling, switching to another thermal fluid or another external application: The
>Bypass
valve<
[62]
must be fully open
before the circulation is started. As a result, the pressure in the
thermal fluid circuit is at the lowest point.
Note the pressure gauge on the
>Touchscreen<
[88] in [Field 8] when starting the circulation.
The allowable pressure of your external application must not be exceeded.
▪
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.
