Page 25: Figure 17: Filling The Bath
Caution: The bath must be places in its intended final position before adding bath fluid. The CT-1000 should never be moved with bath fluid in the bath. Warning: Never use flammable bath liquids. 1. Make sure that the instrument power is OFF and select a bath liquid appropriate to your operating temperature range. -
Page 26: Drain The Bath
Monitor the bath liquid level closely when operating the CT-1000 at higher temperatures (100 °C to 150 °C). The bath liquid expands as the temperature increases. The CT-1000 bath jar is not designed to contain liquid under pressure. If the bath is overfilled the liquid may overflow. -
Page 27: Bath Operation
Bath Operation The various functions controlling the bath are printed at the bottom of the front panel of the CT-1000. These functions, reading from left to right, are listed below, as shown in Figure 18. • Power • Temperature •... -
Page 28: Set Bath Temperature
1. Choose a temperature using the Temperature SELECT switch. Preheat switch activates an auxiliary heater for the CT-1000. Turn it to heat up the bath more rapidly, if desired. If the operational temperature is below 120 °C, turn the Preheat switch when the necessary temperature is reached. -
Page 29: Variable Temperature Adjustments
2. Turn the Temperature Adjust SELECT switch to the right. Preheat switch activates an auxiliary heater for the CT-1000. Turn it to heat up the bath more rapidly, if desired. If the operational temperature is below 120 °C, turn the Preheat switch when the necessary temperature is reached. -

Page 37: Appendix I - Choosing A Temperature Bath Fluid
There are some very expensive halogen-based fluids which might be considered, but these also have a high volatility and may be somewhat toxic. CANNON Instrument Company® | Appendix I – Choosing a Temperature Bath Fluid... -
Page 38: Isopropyl Alcohol
Because these oils turn faintly yellow and continue to darken with prolonged exposure to heat, CANNON recommends adding an oxidation inhibitor to retard discoloration. The addition of an inhibitor prolongs the useful life of the oil, but it eventually becomes as dark as untreated oil. -
Page 39: Appendix Ii - Correct Shaft & Impeller Misalignment
Appendix II – Correct Shaft & Impeller Misalignment Motor-stirrer units supplied by Cannon Instrument Company are checked after assembly to ensure minimum run-out (deviation from concentric rotation) at the impeller end of the shaft. The following instructions are intended to assist in a situation where users are experiencing excessive vibration in the motor-stirrer because of shaft run-out or misalignment of the impeller blades. -
Page 40: Shaft Run-Out Correction
Shaft Run-Out Correction The following procedure is suggested to correct shaft run-out. CANNON advises that the impeller is removed from the instrument while carrying out this procedure. 1. Grasp the motor firmly with the left hand and touch the tip of a soft crayon (a glass marking pencil, for example) momentarily to the side of the shaft near the impeller end while the motor is running. -
Page 41: Appendix Iii - Adjusting Trimpots (Potentiometers)
Temperature Adjust FIXED dial at the midpoint ensures maximum adjustment in either direction to establish the desired temperature if additional adjustment is necessary. Refer to Figure 23. Figure 23: Adjusting Potentiometers CANNON Instrument Company® | Appendix III – Adjusting Trimpots (Potentiometers) - Page 42 Temperature SELECT setting, it may not be possible to obtain settings for temperatures that are widely different from those on the Temperature dial. In this case, use the dial to obtain the desired SELECT Temperature Adjust VARIABLE temperature. CT-1000 Instruction Manual...
