avoided, may result in minor or moderate injury. It is also be used to alert
against unsafe practices.
The lightning ash with arrow symbol, within an equilateral triangle, is
intended to alert the user to the presence of non-insulated "dangerous
voltage" within the unit's enclosure. The voltage magnitude is signicant
enough to constitute a risk of electrical shock.
This label indicates the presence of hot surfaces.
This label indicates read the manual.
The unit construction provides protection against the risk of
electrical shock by grounding appropriate metal parts. The
protection will not function unless the power cord is connected to a
properly grounded outlet. It is the user's responsibility to assure a
proper ground connection is provided. 
Never place the unit in a location or atmosphere where excessive
heat, moisture, or corrosive materials are present. 
Never use corrosive uids with this unit. Use of these uids will void
the manufacturer’s warranty. 
Observe all warning labels. 
Never remove warning labels. 
Refrigerated units should be left in an upright position for 24 hours
before starting. This will ensure the lubrication oil has drained back
into the compressor. 

Requirements
The unit construction provides protection against the risk of electrical
shock by grounding appropriate metal parts. The protection will not
function unless the power cord is connected to a properly grounded
outlet. It is the user's responsibility to assure a proper ground
connection is provided. 
The unit is intended for use on a dedicated outlet. All thermostats are
equipped with automatic thermally-triggered 20 Amp circuit protector.
NOTE If the circuit protector activates allow the unit to cool before
resetting the protector. Restart the unit. Contact us if it activates again. 
The circuit protection is designed to protect the controller, and is not
intended as a substitute for branch circuit protection.
If the unit's power cord is used as the disconnecting device, it must be
easily accessible at all times. 
Operate the unit using only the supplied line cords, never operate
equipment with damaged cords. 
Refer to the bath nameplate on the rear, upper-left-hand corner of the
bath for specic electrical requirements. Voltage deviations of ± 10%
are permissible. The outlet must be rated as suitable for the total power
consumption of the unit, see page 3-4.
NOTE If a bath and thermostat were purchased separately, follow the elec-

Ventilation The unit can operate with 0 clearance on two exhaust sides as long as the
third exhaust side has unrestricted air ow. Blocked ventilation will increase
the unit's temperature, reduce its cooling capacity and, on refrigerated units,
eventually lead to premature compressor failure.

Requirements
Tubing is normally used to connect the pump to an external application.
NOTE Cap the pump nozzle with the supplied tting for maximum pressure
to the external application, it may be necessary to remove the thermostat
from the bath to access the nozzle. 
NOTE The maximum allowable length of tube depends largely on the
size, form and material of the external vessel. The length of tube and its
diameter, combined with the circulating capacity, have a large effect on the
temperature stability. Whenever possible, use a wider tube diameter and place
the application as close as possible to the circulator. 
Extreme operating temperatures will lead to extreme temperatures on
the tube surface, this is even more critical with metal nozzles. 
the required tube material depends on the heat transfer liquid used •
tubes must not be folded or bent•
after prolonged use, tubes may become brittle or they may get very soft, •
check them on a regular basis and replace if necessary

When using the internal bath only, the plumbing connections can be closed
with the supplied plate and union nuts.
Ensure none of the tubing comes in contact with the power cord. 

Tubing Tubing for Thermo Scientic temperature control systems is optional.
Tubing is available in lengths of 0.5, 1.0 and 1.5 meters. Couplings for
connecting tubes are also available. The smallest opening inside the metal
tubes is 10 mm. The metal tubing is provided with coupling nuts (M16 x 1,
DIN 12 879, part 2) at either end.
Please select the proper tubing from the table shown in Section 5.
Ensure the tubing you select will meet your maximum temperature
and pressure requirements. 
Plastic and rubber tubing
If other plastic and rubber tubes are used, ensure that the tubes selected are
fully suitable for the particular application, i.e., that they will not split, crack
or become disengaged from their connections.
Connect the tubing using the supplied tube ttings for 8 or 12 mm i.d. They
are attached to the plumbing connections with a supplied coupling nut.
We highly recommend using foam rubber insulation on the tubing and the
ttings.
Metal tubing
Thermo Scientic metal tubing (stainless steel insulated) offers a particularly
high degree of safety and is suitable for both low and high temperatures/
liquids.
The metal tubing is attached directly to the plumbing connections, gaskets are
not required.
Do not subject tubing to mechanical strain and ensure any specied
bend radius is not exceeded. 

Fluids
The user is always responsible for the uid used. Never use
corrosive uids with this unit. 
Never use 100% glycol. 
Handling and disposal of liquids other than water should be done
in accordance with the uid manufacturers specication and/or the
MSDS for the uid used. 
Always adjust the unit's software to the uid used, see Section 4. 
When using water above 80°C closely monitor the uid level,
frequent top-offs will be required. It will also create steam. 
Water/glycol mixtures require top-offs with pure water, otherwise
the percentage of glycol will increase resulting in high viscosity and
poor performance. 
Thermo Fisher Scientic takes no responsibility for damages caused by
the selection of an unsuitable bath uid.
Unsuitable bath uids are uids which:
are very highly viscous (much higher than 30 mPas at the respective •
working temperature)
have corrosive characteristics or•
tend to break down at high temperatures•
For uid selection consider application requirements, operating
temperature range, material compatibility, safety concerns, and
environmental issues.
5°C to 95°C — Distilled Water or Deionized Water (up to 3 MΩ-cm)
Normal tap water leads to calcareous deposits necessitating frequent unit
decalcication, see table on next page.
Calcium tends to deposit itself on the heating element. The heating
capacity is reduced and service life shortened.
-30°C to 80°C — Water with Glycol
Below 5°C water has to be mixed with a glycol. The amount of glycol
added should cover a temperature range 5°C lower than the operating
temperature of the particular application. This will prevent the water/
glycol from gelling (freezing) near the evaporating coil.
Excess glycol deteriorates the temperature accuracy due to its high
viscosity.
