Make sure you read and understand all instructions and safety precautions
listed in this manual before installing or operating your unit. If you have
any questions concerning the operation of your unit or the information in
this manual, please contact us. See inside cover for contact information.
DANGER indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not
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.
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. 
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 circuit protector located on the rear of the unit is not intended
to act as a disconnecting means. 
Never operate the unit with the immersion circulator removed from
the bath. 

Section 1 Safety
Cole Palmer
Do not mount the immersion circulator backwards on the bath; the line cord could contact the reservoir
uid. Ensure the electrical cords do not come in contact with any of the plumbing connections or
tubing. 
Operate the unit using only the supplied line cord. If the unit's power cord is used as the disconnecting
device, it must be easily accessible at all times. 
Never place the unit in a location or atmosphere where excessive heat, moisture, or corrosive materials
are present. 
Ensure the tubing you select will meet your maximum temperature and pressure requirements. 
Ensure all communication and electrical connections are made prior to starting the unit. 
Many refrigerants which may be undetectable by human senses are heavier than air and will replace
the oxygen in an enclosed area causing loss of consciousness. Refer to the unit's nameplate and the
manufacturer's most current MSDS for additional information. 
Never operate the unit without uid in the reservoir. 
Other than water, before using any uid, or when performing maintenance where contact with the uid
is likely, refer to the manufacturer’s MSDS and EC Safety Data sheet for handling precautions. 
Ensure, that no toxic gases can be generated by the uid. Flammable gases can build up over the uid
during usage. 
Never use corrosive or ammable uids with this unit. Use of these uids will void the manufacturer’s
warranty. 
When using ethylene glycol and water, check the uid concentration and pH on a regular basis. Changes
in concentration and pH can impact system performance. 
Ensure the uid is at a safe temperature (20°C to 55°C) before handling or draining. 
Never operate damaged or leaking equipment, or with any damaged cords. 
Never operate the unit or add uid to the reservoir with panels removed. 
Do not clean the unit with solvents, only use a soft cloth and water. 
Drain the unit before it is transported and/or stored in, near or below freezing temperatures.
Always turn the unit off and disconnect the supply voltage from its power source before moving the unit
or before performing any service or maintenance procedures. 
Transport the unit with care. Sudden jolts or drops can damage the unit's components. 
Refer service and repairs to a qualied technician. 

CAUTION
CAUTION
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
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.
NOTE If the circuit protector activates allow the unit to cool before
resetting. 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. Position the unit so it is
not difcult to operate the disconnecting device.
If the unit's power cord is used as the disconnecting device, it must be
easily accessible at all times. 
Refer to the unit nameplate on the rear, upper-left-hand corner of the

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. 
The uid information is only a guide since specications may change.
Cole Palmer 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.
-40°C to 200°C — SIL180:
SIL180 is suitable for covering nearly the entire range with just one liquid,
especially when used with the cooling units. See next page for additional
information. Unfortunately SIL180 has a wetting tendency necessitating
the occasional cleaning of the bath cover.
other temperatures:
Cole Palmer offers a range of heat transfer uids for these temperature
control applications.
SYNTH 60, SYNTH 200, SYNTH 260:
Synthetic thermal liquid with a medium life span (several months) and
little smell annoyance. See next page for additional information.
SIL 100, SIL 180, SIL 200, SIL 300:
Silicone oil with a very long life span (over 1 year) and negligible smell.
See next page for additional information.
Heat transfer uids are supplied with an EC Safety Data Sheet.
Ensure, when selecting the heat transfer uid, that no toxic gases
can be generated. Flammable gases can build up over the uid
during usage. 
Ensure the over temperature cut-off point is set lower than the re
point for the heat transfer uid selected. 
The highest working temperature as dened by the EN 61010 (IEC
1010) must be limited to 25°C below the re point of the bath uid. 

Unfavorably high total ionized solids (TIS) can accelerate the rate of galvanic
corrosion. These contaminants can function as electrolytes which increase
the potential for galvanic cell corrosion and lead to localized corrosion such
as pitting. Eventually, the pitting will become so extensive that refrigerant will
leak into the water reservoir.
As an example, raw water in the United States averages 171 ppm (of NaCl).
The recommended level for use in a water system is between 0.5 to 5.0 ppm
(of NaCl).
Recommendation: Initially ll the tank with distilled or deionized water. Do
not use untreated tap water as the total ionized solids level may be too high.
This will reduce the electrolytic potential of the water and prevent or reduce
the galvanic corrosion observed.

Filling Requirements
Draining
CAUTION
CAUTION
Ensure the reservoir drain port on the front of the unit is closed and that
all plumbing connections are secure. Also ensure any residue is thoroughly
removed before lling the unit.
Before using any uid refer to the manufacturer’s MSDS and EC
safety data sheets for handling precautions. 
To avoid spilling, place your containers into the bath before lling.
With a low level WARNING the unit continues to run, with a FAULT the
unit will shut the refrigeration, pump and heater will shut down, see Section
7. The low level warning is at approximately 4 cm (1 5/8”) below the top, the
low level fault is at approximately 5.5 cm (2 1/8”).
Avoid overlling, oil-based uids expand when heated. 
When pumping to an external system, keep extra uid on hand to maintain
the proper level in the circulating lines and the external system.
NOTE Monitor the uid level whenever heating the uid. 
Before draining any uid refer to the manufacturer’s MSDS and EC
safety data sheets for handling precautions. 
Ensure the uid is at a safe handling temperature, ~55°C. Wear
protective clothing and gloves. 
place a suitable vessel underneath the drain. If desired, attach an •
8 mm id tube on the drain.
slowly • turn the drain plug until ow is observed.

Precautions
When working with uids other than water:
Do not use any uid until you have read and understood the label and •
the Material Safety Data Sheet (MSDS).
Do not blend any uids. •
Ensure any uid residue or any other material is thoroughly removed •
before lling the unit with a different uid.
Always wear protective clothing, especially a face shield and gloves. •
Avoid spattering on any of the unit's components, always • slowly add uid.
When adding, point the opening of a container away from yourself.
Use fume hoods.•
Do not allow any ignition sources in the vicinity. •
