Page 11: Installation
Chapter Installation Initial Inspection Your FTS Systems CharpyCool™ low-temperature bath was carefully packed and thoroughly inspected before leaving the SP Scientific factory. However, in the unlikely event that shipping damage has occurred, retain all packing material and contact your freight carrier immediately.
Page 12: Installation
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...
Page 13: Installing The Magnetic Stirrer And Vortex Breaker
Installation 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 steel reservoir and from the bottom of the magnetic stirrer.
Page 14 Installation FTS Systems CharpyCool™ Once the stirrer assembly is in place, adjust the four holding screws by hand 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.
Page 15: Operation
Chapter Operation Overview The FTS CharpyCool™ offers a continuous display of temperatures in 0.1 degree increments and is capable of controlling temperatures within ± 0.18 °F (± 0.1 °C) across the equipment’s full operating temperature range. Operation Powering On Note: Before powering on and cooling, install the magnetic stirrer and vortex breaker (as described in Chapter 2) and fill the reservoir with fluid (as described in Chapter 4).
Page 16: The Solo Controller

Toggle the on/off breaker switch to the Off position. The green indicator light will turn off and the CharpyCool™’s refrigeration 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™...
Page 19: Fluid
Improperly selected fluid can result in damage to both your process and your equipment. Refer to the following table for a list of fluids that may be used with the FTS Systems CharpyCool™. CAUTION: BEFORE USING ANY FLUID PRODUCT, READ THE CURRENT PRODUCT MATERIAL SAFETY DATA SHEET AND ANY PRECAUTIONARY STATEMENTS ON THE PRODUCT PACKAGE.
Page 20: Fluid Filling
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.
Page 21: Maintenance
Chapter Maintenance ALWAYS SHUT OFF THE POWER SUPPLY TO THE UNIT BEFORE PERFORMING MAINTENANCE PROCEDURES. ALWAYS NOTIFY THE SP SCIENTIFIC SERVICE DEPARTMENT BEFORE PERFORMING REPAIRS TO A UNIT THAT IS UNDER WARRANTY. FAILURE TO NOTIFY SP SCIENTIFIC SERVICE BEFORE PERFORMING REPAIRS WILL VOID THE FACTORY WARRANTY. Cleaning Condenser The refrigeration system is air-cooled.
Page 22: Compressor Safeties
Compressor Safeties Refrigerant Types and Properties The CharpyCool™ features a cascade refrigeration system comprised of two separate compressors with two separate refrigerants. The first stage, also called a high stage, uses 1.27 ounces of R1270 (Propylene). The second stage, also called the low stage, uses 0.97 ounces of R170 (Ethane).
Page 23: Voltage
FTS Systems CharpyCool™ Maintenance Voltage The voltage should not be above or below 10% of the voltage marked on the tag at the rear of the unit. To determine if the voltage is sufficient, the voltage should be measured while the compressor is drawing its starting current. During this time, any line drops will cause a significant voltage drop in inadequate wiring or on extension cords.
Page 25: Accessories
