Safety glasses must be worn for certain tasks. These safety glasses must
meet existing legal requirements for personal protective equipment valid in
the European Union.
CE protective gloves must be worn for certain tasks. These protective gloves
must meet the legal requirements for personal protective equipment valid in
the European Union.
The overtemperature protection is a safety fitting that prevents flammable
heat transfer liquid from igniting due to high temperatures. All safety com-
ponents on the device are shut down to prevent fire from posing a danger.
An alarm signal also indicates that the overtemperature protection has been
activated. The temperature at which the safety fitting is activated must be
set in line with the heat transfer liquid used.
We recommend testing the overtemperature protection at regular intervals.
See Ä Chapter 7.7 "Checking the overtemperature protection"
on page 117 for further information.
The low-level protection is a safety unit that prevents damage to the device
and prevents the hot heater from igniting combustible heat transfer liquid. If
the heat transfer liquid level in the device falls below a specified level (level
2), a warning is issued initially. If the level continues to fall (level 1), an alarm is
triggered. All safety components on the device are switched off as a result.
We recommend testing the low-level protection at regular intervals.
See Ä Chapter 7.8 "Checking the low-level protection"
on page 118 for further information.
"Hot surface" warning symbols are affixed to the device. This symbol warns
against hot surfaces on the device. These surfaces must not be touched
during operation. These surfaces must be allowed to cool to room tem-
perature before they can be touched during other operation phases such as
servicing.
