Fluids:
Only use the fluids, which fulfill the
requirements for safety, health and
device compatibility� Be aware of
the chemical hazards that may be associated with the
bath fluid used� Observe all safety warning for the fluids�
• Depending on the bath fluid used and the type of opera-
tion or toxic can arise� Ensure suitable extraction�
• Do not use any fluid which may cause dangerous reac-
tions during processing�
• Only use recommended bath fluid� Only use non-acid
and non corroding fluid�
Never operate the device without
sufficient refrigeration carrier flu-
id! Check the fluid level detection
at a regular basis (see the section “Filling and draining”)�
• Continuous monitoring of the bath and the filling level of
the bath fluid is required�
• To ensure a sufficient fluid circulation, the viscosity of
the bath fluid must not exceed of 50 mm
2
/s at the low-
est operating temperature�
• 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�
Don’t use following fluids:
- Untreated tap water
- Acids or bases
- Solutions with halides: chlorides, fluorides, bromides,
iodides or sulfur
- Bleach (Sodium Hypochlorite)
- Solution with chromates or chromium salts
- Glycerine
- Ferrous water�
Battery pack RB 1 (for WiCo):
If during operation the battery
pack RB 1 (rechargeable battery)
becomes fully discharged, the de-
vice (station) will continue to run or is shut down depend-
ing on the value settings for “Time Out”, “Safe Speed”
and “Safe Temperature”� If the device is set so that it con-
tinues to run when the battery of the WiCo is fully dis-
charged, the only means of switching the station off are
the “safe STOP”, “ON/OFF” key and the “Power switch”!
Please note the following
safety instructions for the
battery pack RB 1 (recharge-
able battery):
• Keep the battery pack out of reach of children at all times�
• Store the battery pack in a cool, dry place�
• Never throw the battery pack into a fire� Keep it away from
direct sunlight and temperatures above 60 °C� High tem-
peratures will damage the battery pack and render it unus-
able� Temperatures above 100 °C may cause it to explode�
• Never throw the battery pack into water or expose it to
moisture� Water may lead to a short-circuit, causing the
battery pack to explode�
• Do not deform or crush the battery pack or damage it
in any other way� This can cause battery fluid to leak
and/or the battery pack to explode�
• When not in use, keep battery packs away from pa-
perclips, coins, keys, nails, screws or other small metal
objects which could cause the contacts to be bridged�
Short-circuiting may result in an explosion�

CAUTION
Refrigerant:
The device is not allowed to be
used in an ATEX (Atmosphere Ex-
losible) zone�
Flammable refrigerant used� Do not
use mechanical devices or other
means to accelerate the defrosting
process, other than those recommended by the manufacturer�
Do not damage the refrigerant circuit�
• Insufficient ventilation may result in the formation of ex-
plosive mixtures� Only use the device in well ventilated
areas�
• Flammable refrigerant used� Only the manufacturer may
open and repair the closed refrigeration system�
• The minimum room size is 9 m³, so that in the event of
an error (exit of the complete refrigerant filling quantity)
no flammable refrigerant-air mixture can arise (R 290
max� 8 g/m³ ambient air)�
WARNING
WARNING
• Do not transport or empty the bath while it is still cold�
Check the temperature of the bath fluid before draining�
• Always empty the bath before moving the unit�
Always empty the bath if the unit
is unused for long time�
