6.3 Filling and emptying
LAUDA accepts no liability for damage caused by the use of unsuitable heat transfer liquids (approved
heat transfer liquids (Ì 6.4)).
Caution !
Contact with heat transfer liquid when filling / draining
Harmful when inhaled,
damage to eyes and skin
• Pay attention to the safety data sheet for the heat
transfer liquid.
• Use CE gloves, protective clothing and eye protec-
tion during physical contact with heat transfer liquid.
• Avoid splashing the heat transfer liquid.
• Make sure that the drain tap is closed before filling.
Caution !
Use of unsuitable heat transfer liquids
Explosion, burns, scalds, fire
• When selecting the heat transfer liquid, observe the
admissible temperature range.
• Only use LAUDA heat transfer liquids.
Notice
Overfilling containers, spilling heat transfer liquid
Environmental hazard from leaking heat transfer liquid
• Note the thermal volume expansion of the heat trans-
fer liquid.
• Where necessary, consider the displacement volume
of the body being introduced.
• Take the volume of external consumers into account.
Filling
− Withdraw the drain tap.
− Optimum operation is ensured with a filling level of 20-40 mm below the bath bridge (max. filling level:
20 mm).
− Operation is possible down to a filling level of 60 mm below the bath bridge; a low level alarm occurs
from a filling level of approx. 90 mm below the bath bridge. (Ì 8.1)
−
Whe
n using oils as heat transfer liquids note that they expand on heating (approx. 10 % per 100 °C).
− Take into account the displacement volume of any objects to be introduced into the bath.
− With a connected external consumer the complete expansion takes place in the bath.
