1Connect the PROCESS OUTLET to the

uid inlet on your application. Connect the PROCESS

INLET to the uid outlet on your application.

Ensure all connections are secure and that the proper

sealant/lubricant for the tting material is used. (If

Teon® tape is used, ensure the tape does not overhang

the rst thread as it could shred and get into the uid.)

Acceptable uids are:

Safety Precautions:

The unit is designed for indoor use only.

Neverplaceunitinalocationwhereexcessiveheat,moisture,inadequateventilation,

orcorrosivematerialsarepresent.

Neveruseammableorcorrosiveuidswiththisunit.

Neverconnectprocessuidlinestoyourfacilitywatersupplyortoanypressurized

liquidsource.

Ifyourunitisequippedwithapositivedisplacementpump(PD1orPD2),ensureyour

applicationplumbinglinesandttingsareratedtowithstandaminimumof115psi.

Beforeusinganyuidorperformingmaintenancewherecontactwiththeuidislikely

refertothemanufacturer’sMSDSforhandlingprecautions.

2 Ensure the reservoir drain plug on the back of the

unit is in place and that all plumbing connections are secure.

Loosen the two thumbscrews securing the reservoir cover

to the unit. Ensure the uid lter is securely in place in

the bottom of the reservoir. Slowly ll the unit with clean

process uid until the uid reaches the reservoir's lip.

Since the reservoir capacity may be small compared to your

application and air may need to be purged from the lines,

have extra cooling uid on hand to keep the system topped

off when external circulation is started. Failure to keep the

reservoir full to the lip will result in loss of cooling capacity.

Replace the reservoir cover and tighten the thumbscrews.

The lid must remain secure to minimize evaporation and

keep debris out of the reservoir.

3Verify the appropriate voltage. Insert female end of

power cord into the chiller power inlet and then insert male

end of power cord into a power outlet.

4Place the circuit protector to the up position, the

controller will ash and the alarm will momentarily sound.

See next page.

Press . The controller will do a self-test (the controller will quickly sequence through its LEDs and

momentarily sound the alarm) and then display the recirculating uid temperature. The refrigeration system and

the recirculation pump will then start. The RECIRCULATING PRESSURE gauge will display the pump operating

pressure. If the pressure needs adjusting, refer to Section 3 in the manual.

NOTE If on start up the unit's recirculating uid is outside either temperature limit, the unit will operate but the

appropriate indicator will ash until the uid is within the limit. 

To display/change the setpoint use the arrow keys, will illuminate.

NOTE If the arrow keys are not pressed within 10 seconds the display will return to the current reservoir

temperature. The controller will not allow you to enter a setpoint closer than 2°C of either temperature alarm

setting. Trying to use a setpoint within 2°C causes the appropriate indicator to ash and sounds the audible alarm

twice. 

Once the desired setpoint is displayed, press to conrm the change. The display will rapidly ash the new value

for a short period and then return to the recirculating uid temperature.

Use this key to

toggle the unit on

or off.

Indicates refrigeration system status.

Indicates the

controller is displaying

the setpoint. Press the

arrow keys to change

the value.

Pressure Gauge

Indicates the controller is

displaying the unit's low

temperature alarm setting.

Indicates the controller is

displaying the high temperature

alarm setting.

Optional. Indicates the unit

is operating in the serial

communication mode.

Press to change the

displayed value.

Press to sequence through the

four indicators and accept the

displayed value.

Unpacking

Cole Parmer Polystat 1-1

Make sure you read and understand all instructions and safety precautions

listed in this manual before installing or operating your chiller. If you have

any questions concerning the operation of your chiller 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 chiller's enclosure. The voltage magnitude is signicant

enough to constitute a risk of electrical shock.

This label indicates read the manual.

NOTE The chiller's equipment design incorporates a complete sheet metal

enclosure for personnel protection from mechanical and electrical hazards. 

Observe all warning labels. 

Never remove warning labels. 

The chiller 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 chiller is not intended

to act as a disconnecting means. 

If the chiller's power cord is used as the disconnecting device, it

must be easily accessible at all times. 

Never operate the chiller with damaged cords. 

Never place the chiller in a location or atmosphere where excessive

heat, moisture, or corrosive materials are present. 

Section 1

Cole Parmer

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 chiller's

nameplate and the manufacturer's most current MSDS for additional information. 

Never connect the process uid inlet or outlet ttings to your building water supply or

any water pressure source. 

Never operate the chiller 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. 

Do not use automotive antifreeze. Commercial antifreeze contains silicates, or any

Organic Acid Technologies (OATs), that can damage the pump seals. Use of automotive

antifreeze will void the manufacturer’s warranty. 

Never use corrosive or ammable uids with this chiller. Use of these uids will also void

the manufacturer’s warranty. 

When using a process uid mixture of ethylene glycol and water or propylene glycol and

water, check the uid concentration and pH on a regular basis. Changes in concentration

and pH can impact system performance. See Section 3. 

Never operate damaged or leaking equipment. 

Never operate the chiller or add uid to the reservoir with panels removed. 

Do not clean the chiller with solvents, only use a soft cloth and water. 

Drain the chiller before it is transported and/or stored in, near or below freezing

temperatures. Store the chiller in the temperature range -25°C to 60°C (with packaging),

and <80% relative humidity. 

Always turn the chiller off and disconnect the supply voltage from its power source

before moving the chiller or before performing any service or maintenance procedures. 

Transport the chiller with care. Sudden jolts or drops can damage its components. 

Refer service and repairs to a qualied technician. 

Performance of installation, operation, or maintenance procedures other than

those described in this manual may result in a hazardous situation and will void the

manufacturer's warranty. 
