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).
4.3.1 Externally closed application
Operating an externally closed system with >Isolating sleeve< [27] installed
BURSTING DUE TO OVERPRESSURE DURING TEMPERATURE CONTROL.
 Shut down the temperature control unit immediately.
 Allow the thermal fluid to cool to room temperature.
 Prior to starting up the temperature control unit with an externally closed system, remove the
>Isolating sleeve< [27] (see page 33, in section »Mounting/removing the isolating sleeve (op-
tional)«).
 In case of standard devices, open the >Venting valve expansion vessel< [21] by turning it anti-
clockwise (turn 90° left as far as it will go).
4.3.1.1 Filling and venting externally closed application
Non-compliance with the safety data sheet for the thermofluid to be used
INJURIES
 Risk of injury to the eyes, skin, respiratory tract.
 The safety data sheet for the thermofluid to be used must be read prior to use and its contents
respected.
 Observe the local regulations/work instructions.
 Wear your personnel 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 thermofluid and material on page 16 in section
»Proper disposal of resources 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 monitor the thermal fluid level in the >Sight glass< [23]. Fill up the thermal fluid
during the venting phase so the thermal fluid level does not fall below the minimum mark in
the >Expansion vessel< [18].
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 > Extra expansion vessel< [19] (optional)]
+ [Volume of the thermal fluid hoses] + [Jacket volume of your application] + [10% / 100 K].
