Thank you for choosing Anova Temperature Control Instruments!
This manual covers basic operational usage of our circulators. For optimal utilization of all functions, we
recommend that you thoroughly study this manual prior to beginning operation. Anova does not directly support
OEM systems or system branded for other companies. OEM systems may contain different specifications and
features that are not covered in this manual. This manual also does not include usage instructions for OEM /
custom designed systems because they typically run custom software designed by other companies.

Unpack the circulator and accessories and inspect them for
possible transport damage.
Wait 24 hours before Power On for Max Cooling Capacity on
Refrigerated Systems
Immediately report damage to Anova and the responsible carrier.
Failures to report transport damage will not allow us to support your claim for insurance.

Introduction
Anova circulators control the temperature of specific fluids in a bath tank. The system features a pump
connection for temperature control of external systems in a closed loop circuit.
Anova circulators are not for direct temperature control. Direct temperature control means direct contact
of the object with the bath fluid. This includes food, tobacco, pharmaceutical and other consumed organic
products.
Do not use Anova circulators to directly cook food – at no time should food products come in contact with
bath fluid. Food must by vacuum-sealed before use with circulator.

Safety
Anova products ensure safe operation when installed, operated, and maintained according to
Safety recommendations in this manual. This section explains the potential dangers that may
arise when operating Anova circulator and notes many important safety precautions.
FIRE HAZARD
Be careful when filling the bath with flammable fluids
Observe fluid flash points and adjust safety dial
Observe all warnings for bath fluids and the respective safety datasheets
Only use the system in well-ventilated areas when using flammable fluids
Insufficient ventilation may result in the formation of explosive mixtures
DO NOT OPERATE WITH SUSPECTED FAILURES
Do not run circulation fluids above their boiling point
Do not crimped circulation lines.
Do not circulate cold fluid into hot glassware
Do not set safety temperature limiter above fluid flash points.
Anova is not responsible for any damage that might result from examples similar to above
BURN HAZARD
Do not touch connectors and bath cover or fluids when bath is under high temperature
OBSERVE ALL WARNING LABELS ON PRODUCT
Read all labels on product to ensure proper usage.
GROUND PRODUCT
Proper grounding is required.
Operational Safety
Follow the safety instructions to avoid personal injury and property damage.
Fluids Safety:
●Set the temperature safety dial to at least 25 °C below the flash point of the bath fluid.
●Never operate the system without bath fluid in the bath.
●Do not introduce water into hot oil.
●Pay attention to the thermal expansion of bath oil during heating to avoid overflows.
●Do not drain the bath fluid while it is hot!
Circulation Safety:
●Note the temperature range of plastic bath tanks and tubing – they melt!!!
●Avoid bent and crimped tubing in the tubing, and maintain a sufficient distance from
surrounding walls.
●Regularly check the tubing for material defects (e.g., for cracks and leaks).
Installation and transport safety:
●Place the system on an even surface to prevent spills and tip over.
●Do not operate damaged or leaking units.
●Disconnect power before cleaning the unit.
●Sudden jolts or drops may cause damage in the interior of the unit.
●Do not remove warning labels.

Application Safety:
Temperature controlling the contents of a reactor constitutes normal circulator practice.
However, we do not know what substances are contained within reactor vessels and cannot help
with determining the safety of your applications.
Many chemicals are:
●Flammable or explosive
●Hazardous to health
●environmentally unsafe
Many materials and reaction processes are unstable at room temperature.
The user alone is responsible for the handling of these substances and determining the safety of his or
her individual applications.
Installation
•Wait at least an hour to setup the system after transportation. This will allow any compressor oil to drain
back into the compressor. Failure to do so will compromise the cooling performance of the system.
• The installation location should be large enough and provide sufficient air ventilation.
• Keep at least 1 foot of open space on the front and rear vents.
• Do not set up the unit in the immediate vicinity of heat sources.
• Do not install in outdoors and do not expose to sun light.
• Make sure that the power supply has low impedance.
• Ambient temperature range: 40 °C, min. 5 °C.
• Relative humidity: 50% (40 °C).
Safe Bath fluids
Caution:
Carefully read the safety data sheet of the bath fluid, pay attention to the fluid flash point!
Use only non-acidic and non-corrosive bath fluids.
If user chooses to use non-approved fluids make sure they are non-corroding.
If using hazardous materials or materials that could become hazardous, the operator must affix safety
labels to the front of the unit so they are highly visible.
Recommended Bath Fluids:

8
Fluid recommendations for cold temps:
Temperature ranges 1°C -20°C: Ethanol or water/glycol mixture 1:1
Temperature ranges -20°C to -40°C: Dynalene
Fluid recommendations for hot temps:
Temperature ranges 1°C to 80C: Soft/decalcified water or distilled water only. Tap water quality is highly
variable based on local conditions.
Temperature ranges 80 °C to 200 °C: Mineral/silicone oils
Warning:
• Hard water leads to calcification in the bath.
• Ferrous water can cause corrosion.
• Chloric water can cause pitting corrosion.
• Lab distilled and deionized water can cause corrosion if used long term, even in stainless steel.
Fire or other dangers when using bath fluids that are not recommended:
Please contact Anova before using other than recommended bath fluids. Anova assumes no liability for
damage caused by the selection of an unsuitable bath liquid.
Unsuitable bath fluids are fluids which:
• are highly viscous
• have creep characteristics
• have corrosive characteristics
Filling
Take care that no liquid enters the interior of the circulator.
Recommended maximum filling level of 1.5 Inches below the rim.
Pay attention to overflow of liquid.
Do not drain the bath fluid while it is hot!

Disposal
This product uses bath fluids that might partially consist of mineral oil or synthetic oil. For disposal,
observe the instructions in the safety data sheets. Some systems contains common refrigerants found in
household products please contact your local waste management company to determine disposal
requirements.
