• After a power failure during operation, the device may
start automatically (depending on operating mode).
• Transport the device with care.
• Do not transport or empty the bath while it is still hot.
This may result in accidents, especially scalding injuries.
Fluids
Only use uids, which fulll the re-
quirements for safety, health and
device compatibility. Be aware of
the chemical hazards that may be associated with the
bath uid used. Observe all safety warnings for the uids.
• Depending on the bath uid used and the type of opera-
tion, toxic or ammable vapors can arise. Ensure suit-
able extraction.
• Do not use any uid which may cause dangerous reac-
tions during processing.
• Only use recommended bath uid. Only use non-acid
and non corroding uid.
Only process and heat up any uid
that has a ash point higher than
the adjusted safe temperature limit
that has been set. The safe temperature limit must al-
ways be set to at least 25 ºC lower than the ash point
of the uid used. Examine regularly the function of the
safety temperature limiter.
Never operate the device without
sucient heat carrier uid! You
should also be careful to ensure
that the minimum clearances and immersion depths in
the uid are observed. Check the uid level detection at
a regular basis (see the chapter "Filling and draining").
• Continuous monitoring of the bath and the lling level of
the bath uid is required, especially at high temperatures.
• For optimum temperature stability, the uids viscosity
should be 50 mm
2
/s or less at its lowest operating tem-
perature. This permits good uid circulation and mini-
mizes heating from the pump.
If water is used at higher tempera-
ture, there is heavy loss of uid due
to the condensation of evapora-
tion steam.
• Untreated tap water is not recommended. It is recom-
mended to use distilled water or high purity water (ion
exchangers) and add 0,1 g soda (sodium carbonate
Na
2
CO

) /liter, to reduce corrosive properties.
Risk of burning caused by vapor or
hot water at the outlet of the cool-
ing coil.
Do not use the cooling coil with
water at bath temperatures > 95°
C.
For bath temperatures > 60°C make
sure that the ow rate through the
cooling coil is high enough.
Don't use following uids:
- Untreated tap water
- Concentration of acids or bases
- Solutions with halides: chlorides, uorides, bromides,
iodides or sulfur
- Bleach (Sodium Hypochlorite)
- Solution with chromates or chromium salts
- Glycerine
- Ferrous water.
When changing the bath uid
from water to a heat transfer uid
for temperatures above 100 °C, re-
move the remaining water from the complete system
(including hoses and external devices). When doing this,
also open the stopper and union nuts caps of the pump
outputs and inputs and blow compressed air through
all the pump outputs and inputs! Beware of the risk of
burning due to delay in boiling!
