Unpacking If the chiller has a line cord it is located under the shipping crate’s lid. Do
not discard the lid until the cord is located.

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 signicant
enough to constitute a risk of electrical shock.
This label indicates read the manual.
Never place the chiller in a location where excessive heat, moisture,
or corrosive materials are present.
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.
Never connect the process uid inlet or outlet ttings to your
building water supply or any water pressure source.
Do not use automotive antifreeze. Commercial antifreeze contains
silicates 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 ThermoFlex24000 chillers require the use of 50/50 EG/
water or 50/50 PG/water below 10°C process temperature.

Before using any uid or performing maintenance where contact
with the uid is likely refer to the manufacturer’s MSDS for handling
precautions.
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.
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. Contact with leaking refrigerant
will cause skin burns. Refer to the chiller's nameplate and the
manufacturer's most current MSDS for additional information.
Performance of installation, operation, or maintenance procedures
other than those described in this manual may result in a hazardous
situation and may void the manufacturer's warranty.
Transport the chiller with care. Sudden jolts or drops can damage its
components.
Drain the chiller before it is transported and/or stored in near or
below freezing temperatures, see Draining in Section 8. Store the
chiller in the temperature range -25°C to 60°C (with packaging), and
<80% relative humidity.
For ThermoFlex900-10000 chillers, the circuit protector located on
the rear is not intended to act as a disconnecting means.
Observe and never remove warning labels.
Never operate damaged or leaking equipment.
Never operate the chiller without process uid in the reservoir.
Always turn off the chiller and disconnect the power cord from
the power source before performing any service or maintenance
procedures, or before moving.
Never operate the chiller with panels removed.
Never operate equipment with damaged power cords.
Refer service and repairs to a qualied technician.
