Safety instructions and basic principles
Connection/adjustment to the power supply not carried out by an electrician and/or connection
to a power socket without protective earth (PE)
MORTAL DANGER FROM ELECTRIC SHOCK
Have the connection/adjustment to the power supply carried out by an electrician.
Always connect the temperature control unit to safety sockets (PE).
Damaged power cable/power cable connection
MORTAL DANGER FROM ELECTRIC SHOCK
Do not start up the temperature control unit.
Isolate the temperature control unit from the power supply.
Have the power supply cable/power supply connection replaced and inspected by an electri-
cian.
Risk of tipping due to unstable temperature control unit
SERIOUS INJURY AND PROPERTY DAMAGE
Avoid risk of tipping due to unstable temperature control unit.
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«
.
Hot or very cold thermal fluid
SERIOUS BURNS/FREEZING OF LIMBS
Before draining, ensure that the thermal fluid has room temperature (20 °C).
If, at this temperature, the thermal fluid is too viscous to be drained: Control the temperature
of the thermal fluid for a few minutes until the viscosity will allow drainage. Never control the
temperature of the thermal fluid when the Drain is open.
Danger of burns when draining thermal fluids at temperatures above 20
°C.
Wear your personal protective equipment when carrying out the drain operation.
Only drain with a suitable draining hose and container. These must be resistant to the thermal
fluid and the temperature.
All safety instructions are important and must be followed accordingly during working operations!
