Correct use
• Use:
Use
HRC 2
(Heated Recirculating Chiller) for tempering
and circulating fluids�
Intended Use: Tabletop device
• Range of use (indoor use only):
- Laboratories
- Schools
- Pharmacies
- Universities
This instrument is suitable for use in all areas except:
- Residential areas
- Areas that are connected directly to a low-voltage supply
network that also supplies residential areas�
The safety of the user cannot be guaranteed:
- If the device is operated with accessories that are not sup-
plied or recommended by
IKA
®
�
- If the device is operated improperly or in contrary to the
IKA
®
specifications�
- If the device or the printed circuit board are modified by
third parties�
• Continuous monitoring of the bath and the filling level of
the bath fluid is required, especially at high temperatures�
• To ensure a sufficient fluid circulation, the viscosity of the
bath fluid must not exceed of 50mm
2
/s at the lowest op-
erating temperature�
If water is used at higher tempera-
ture, there is heavy loss of fluid due
to the evaporation of the steam�
• Untreated tap water is not recommended� It is recom-
mended to use distilled water or high purity water (ion ex-
changers) and add 0�1 g soda (sodium carbonate Na
2
CO
3
)
/liter, to reduce corrosive properties�
Risk of burning caused by vapor or
hot water at the outlet of the cool-
ing coil�
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�
When changing the bath fluid type,
must remove the remaining water
from the complete system (includ-
ing hoses and external devices)� When doing this, also
open the stopper and union nuts caps of the pump out-
puts and inputs and blow compressed air through all the
pump outputs and inputs! Beware of the risk of burning
due to delay in boiling!
• Do not transport or empty the bath while it is still hot/
cold� This may result in accidents, especially scalding inju-
ries or frostbite�
Fluids:
Beware of the risk of burning due
to delay in boiling!
Only use fluids, which fulfill the re-
quirements for safety, health and
device compatibility� Be aware of
the chemical hazards that may be associated with the bath
fluid used� Observe all safety warnings for the fluids�
• Depending on the bath fluid used and the type of opera-
tion, toxic or flammable vapors can arise� Ensure suitable
extraction�
• Do not use any fluid which may cause dangerous reac-
tions during processing�
• Only use recommended bath fluids� Only use non-acid
and non corroding fluids�
Only process and heat up any fluid
that has a flash point higher than
the adjusted safe temperature limit
that has been set� The safe temperature limit must always
be set to at least 25 ºC lower than the flash point of the
fluid used� Examine regularly the function of the safety
temperature limiter�
Never operate the device without
sufficient heat carrier fluid! Check
the fluid level detection at a regular
basis (see the chapter “Filling and draining”)�
