Slowly fill reservoir with clean process fluid (see Table 1),
utilizing sight tube for easy fluid level monitoring. When the reser- voir is full replace the reservoir cap, hand tight. Since the reservoir capacity may be small compared to your application and air may need to be purged from the lines, have extra cooling fluid on hand to keep the system topped off when external circulation is started.
Pull out the plastic shipping plugs. Remove the reservoir cap by unscrewing it counter-
clockwise.
Verify the appropriate voltage. For chillers supplied with a line
cord, insert female end of power cord into chiller and then insert male end of power cord into power outlet. (The line cord is located under the
shipping crate’s lid. Do not discard the lid until the cord is located.)
Connect the ThermoFlex FACILITY OUTLET (A) to your facility
water return or drain. Connect the ThermoFlex FACILITY INLET (B) to your facility water supply. Ensure the connections are sealed and secure.
Safety Precautions:
The chiller is designed for indoor use only. Never place chiller in a location where excessive heat, moisture, inadequate ventilation, or corrosive materials are present. Never connect process fluid lines to your facility water supply or to any pressurized liquid source. If your chiller is equipped with a positive displacement pump (P1 or P2), ensure your application plumbing lines and fittings are rated to withstand a minimum of 185 psi. Before using any fluid or performing maintenance where contact with the fluid is likely refer to the manufacturer’s MSDS for handling precautions.
For water-cooled chillers only.

Note: Be careful not to fill the reservoir above MAX LEVEL fill line. This will result in a over flow error (O FLO) which will cause the chiller to shut down.
Note: ThermoFlex900-5000 chillers equipped with the Variable Voltage or Global Voltage
option have a voltage configuration panel located behind an access panel on the rear of the chiller. Refer to the Voltage Instruction Sheet shipped with the chiller, or see manual Appendix B. Note: For chillers requiring hard wiring see Section 3 in the manual.

Safety Warnings
Section 1 Safety
DANGER
WARNING
CAUTION
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 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.
Observe all warning labels. 
Never remove warning labels. 
The chiller's 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. 

Thermo Scientific
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. 
To prevent freezing/glazing of the plate exchanger, ThermoFlex7500 through
ThermoFlex24000s require the use of 50/50 EG/water or 50/50 PG/water below 10°C
process temperature. 
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 it 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 or before performing any service or maintenance procedures. 
Transport the chiller with care. Sudden jolts or drops can damage the 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. 
