and related parts for visible damage and leaks. Check for visible liquid at or near the
base of the unit. The reservoir should be clean and dry.
If concealed damage or loss is discovered, contact the freight carrier immediately.2
Keep all contents, packing material and related paperwork intact until a written report
is obtained.
Note: SP Scientific will cooperate in the matter of collecting your claim, but is not responsible
for the collection or free replacement of the material. When possible, replacement parts will be
shipped and invoiced to you, making them a part of your claim.
2“Concealed damage or loss” refers to damage or loss that does not become apparent until the merchandise has been
unpacked and inspected. Should damage or loss be discovered, you may make a written request for inspection by the carrier's
agent within 15 days of the delivery date. You may then file a claim with the freight carrier or SP Scientific, depending on the
terms of your shipment. If your shipment was “FOB Destination” file your claim with SP Scientific and include the inspection
report and any other supporting documents. If your shipment was “FOB Shipping Point” file your claim with the freight carrier

Installation
FTS Systems CharpyCool™
4 Rev 001, 01/12
© SP Scientific 2012
Installation
The FTS Systems CharpyCool™ is designed for bench-top installation in a laboratory
environment. The unit should be installed on a firm, level surface in a location that is
convenient for both operation and service.
NEVER PLACE THE UNIT IN AN AREA WHERE EXCESSIVE HEAT, MOISTURE OR CORROSIVE
MATERIALS ARE PRESENT.
Air Flow Considerations
The FTS Systems CharpyCool™ is equipped with an air-cooled refrigeration system.
Air is pulled from the left side of the unit to cool the refrigeration system components
and then exits the rear panel. When positioning your system, ensure that it is located
on a firm, level surface in an area that provides adequate air circulation.
Inadequate airflow will degrade the unit’s cooling capacity and in extreme cases may
result in compressor failure. A minimum of six (6) inches of clearance on all sides of
the unit is required to ensure proper airflow and avoid damage to the refrigeration
system.
Ambient Conditions
For best low-temperature operation, consider that the ideal ambient temperature for
your FTS Systems CharpyCool™ is approximately 72 °F (22 °C). Higher ambient
temperatures will limit the system’s ability to achieve its ultimate low temperature.
NEVER OPERATE THE FTS SYSTEMS CHARPYCOOL™ IN AN AREA WITH AN AMBIENT
TEMPERATURE ABOVE 90 °F (32 °C).
Services and Utilities
The FTS Systems CharpyCool™’s serial tag, which is located on the unit’s back
panel, provides the unit serial number, and electrical requirements. Ensure that the
voltage, phase, frequency and amperage listed on the serial tag match your facility’s
available power supply (e.g., as a minimum the power outlet you intend to use must
meet the requirements listed on the serial tag).
CAUTION! IF YOU ARE UNSURE ABOUT THE AVAILABLE ELECTRICAL VOLTAGE SUPPLY IN
YOUR FACILITY, CONSULT A QUALIFIED ELECTRICIAN.
Prior to connecting your FTS Systems CharpyCool™ to the available electrical supply,
ensure that the Main Power switch is in the Off position. You may connect the unit to
the available electrical supply at this time.

Installing the Magnetic Stirrer and Vortex Breaker
The FTS CharpyCool™ is equipped with a solid-state variable speed-controlled
magnetic stirrer and a vortex breaker to provide more accurate temperature control
and uniformity. To install the magnetic stirrer and vortex breaker:
Remove the packaging washers from the inside of the stainless steel1. reservoir and from the bottom of the magnetic stirrer. These washers are
placed on the magnetic components of the unit for shipping purposes only
and are intended to be removed prior to operation.
Place the magnetic stirrer, magnet side down, into the center of the reservoir.2. (Pushing the edges of the stirring mechanism beyond the black gasket at the
top of the reservoir may require some force.) As you lower the magnetic
stirrer into place, be careful not to bend or tweak the metal temperature probe
that hangs inside the reservoir.
Note: The screws on top of the magnetic stirrer should not come in contact with the
sides of the bath as you place the magnetic stirrer into the reservoir. If they do, retract
them using your fingers or a screwdriver.

Once the stirrer assembly is in place, adjust the four holding screws by hand3. so that each screw lightly touches the side of the reservoir. Then, use a
screwdriver to further extend each screw so that the stirrer is held snugly in
place in the center of the reservoir. Be sure that all screws are extended to
the same length; this will keep the stirrer assembly centered in the bath.
Hold the vortex breaker by its metal handle (a small tab, bent 90° at the tip)4. and place it into the reservoir so that it rests evenly on top of the magnetic
stirrer. (Pushing the edges of the vortex breaker beyond the black gasket at
the top of the reservoir may require some force.)

Magnetic Stirrer
To operate the magnetic stirrer:
Activate the magnetic stirrer by rotating the Fluid Stir Control Dial clockwise.1.
Adjust the rotational speed of the stirrer by turning the Fluid Stir Control Dial2. clockwise (to increase the speed) and/or counterclockwise (to decrease the
speed).
To deactivate the stirrer, rotate the Fluid Stir Control Dial counterclockwise.3.
The magnetic stirrer may be turned on or off at any time for procedural purposes, but
in general, the unit should not be operated without stirring. If the reservoir fluid is not
agitated, the fluid may exhibit thermal variations. SP Scientific recommends setting
the Fluid Stir control dial to its maximum speed at all times for optimal operation and
performance.
Note: Do not operate the magnetic stirrer without fluid in the reservoir.
Powering Off
To power off the CharpyCool™:
Toggle the on/off breaker switch to the Off position.1.
The green indicator light will turn off and the CharpyCool™’s refrigeration2. system compressor(s) will stop.
Note: When the CharpyCool™ is not in use, ensure that the bath reservoir lid is closed to
prevent evaporation of the cooling fluid.
Restarting Due to the nature of the refrigeration system and its compressor, the CharpyCool™
should never be restarted immediately after it is powered off. SP Scientific
recommends waiting approximately five (5) minutes between shutting down and
restarting the CharpyCool™.

Fluid Filling
While operating at or above ambient temperature (approximately 72 °F or 22 °C), fill
the reservoir with your selected fluid until the fluid is about 1 inch below the gasket.
If you add fluid while the system is at a sub-ambient temperature and you fail to drain
fluid before returning the system to room temperature, the fluid may expand and
overflow the fluid reservoir.
Notes: Fluids will typically contract when cooled and expand when heated.
The gasket at the top of the fluid reservoir does not provide a liquid tight seal.
If the fluid reservoir chamber is overfilled, the liquid will flow over the rim of the fluid
reservoir into the polyurethane insulation. Organic solvents will attack, dissolve and/or
render ineffective the chamber insulation. When the insulation is saturated with
solvent, the CharpyCool™ may be unable to reach its maximum low temperature.
IF THE RESERVOIR IS OVERFILLED, THE FLUID MAY OVERFLOW THE RESERVOIR RIM AND
SEEP INTO THE POLYURETHANE INSULATION. ORGANIC SOLVENTS WILL ATTACK AND
DAMAGE THIS INSULATION MATERIAL, RENDERING THE INSULATION INEFFECTIVE.
WITHOUT ADEQUATE INSULATION, THE CHARPYCOOL™ WILL NOT REACH MAXIMUM LOW
TEMPERATURES.
Magnetic Stirrer
You may switch on your magnetic stirrer once the reservoir has been properly filled
with fluid. The magnetic stirrer must be on for the system to operate properly. Refer to
the magnetic stirrer operation section of the previous chapter for additional
information.
Note: Do not operate the magnetic stirrer without fluid in the reservoir. Be sure the stirrer is
turned off before emptying fluid from the reservoir.
