Confirm that the power supply is suitable for this equipment. Refer to the equipment rating plate for details. To control temperature effectively, the equipment should be located in a stable ambient. WARNING: Ensure that the electrical outlet is earthed and is of the correct voltage and is capable of carrying the stated current load. INTENDED USE This equipment is used to provide a convenient method of melting embedded media (wax) from tissue samples. CAUTION: The range of equipment described here is not to be used in conjunction with large quantities of water. The introduction of water into the glass dish recess could result in premature failure of components.

4 4 WARNING: Do not use flammable solvents or combustible materials as fire or explosion may occur. This equipment uses components which may be a source of ignition. FUNCTION To provide an accurate controlled water temperature of ambient +5ºC to +60ºC. PRINCIPLE OF OPERATION The illuminated flotation bath is designed to be light weight and portable. It is ideally suited for use in the Histology laboratory. The heater body and surrounding area is insulated to minimise heat loss. The desired operating temperature is set at the temperature controller. The temperature sensor is located within a spring clip and is designed to rest against the glass insert (dish). The signal from the temperature sensor is monitored by the temperature controller. The resultant calculated pulsed output is directed to a solid state relay that switches power to the heating element located below the base of the well. The warmed base of the well gently and uniformly heats the water within the glass dish. The amount of energy is determined by the temperature sensor (spring loaded against the glass dish). Energy movement is by convection. This limited effect results in an even temperature gradient throughout the bath. The low wattage fluorescent lamp is activated by the press of a button. PERFORMANCE The operating range for this equipment is ambient +5ºC to 60 C with a control accuracy of +/- 0.5ºC MAXIMUM TEMPERATURE For this product is 60 C. C-TICK The equipment referred to here complies with requirement of AS/NZS 1044:1995 electromagnetic interference (EMI). INSTALLATION (Refer to Unpacking Page 3) Place the equipment in a well-ventilated area, on a firm level surface and ensure that a suitable power supply is available. WARNING: Ensure that the electrical outlet is earthed and is of the correct voltage and is capable of carrying the equipment stated current load (AMPS).

5 5 The model TFB is suitable for bench top use only. MAINTENANCE The Thermoline Scientific Flotation bath requires no routine maintenance other than normal levels of cleanliness. The glass insert may be removed for cleaning. The external case and the stainless steel surfaces may be wiped clean using a damp, soft cloth. Note: Stainless steel is under most conditions extremely resistant to corrosion. This is in part due to the addition of chromium and nickel to the steel and the formation of a durable chromium oxide at the surface during the manufacturing process. There are several chemicals which will attack the surface of stainless steel. Always have in place a program of regular cleaning using a soft damp cloth with a mild solutions of soap and water and allow to dry. TECHNICAL ASSISTANCE If you require additional operational or technical information regarding this equipment please contact: Thermoline Scientific Customer Service Division Telephone: Facsimile: thermoline@thermoline.com.au EXPLANATION OF CONTROLS The controls are located in a control enclosure to the right hand side of the bath. MAIN SWITCH: This is a combination power switch and circuit breaker, when pressed this switch allows power to be supplied to the controls. Incorporated in the face of the switch is a MAINS ON light. CAUTION: The equipment is fitted with a combination circuit breaker/switch. If the switch continues to trip, it may indicate an electrical fault exists. Switch off the power on consult a qualified technician. TEMPERATURE CONTROL/SENSOR: This is an Omron E5CC digital control scaled a 0.1ºC increments and has been configured to provide stable control with minimum of overshoot and quick recovery time. Sensor type is a RTD Pt100. Maximum recommended temperature is 55ºC.

6 6 Page button: Used to view calibration offset parameter. Scroll button: Not used by the operator. Side arrow: Used to move the cursor when changing temperature. Down arrow: Used to decrease parameter setting. Up arrow: Used to increase parameter setting. LIGHT SWITCH: This is a push button, press to turn light on, press again to turn light off. When activated, the fluorescent light will be illuminated.

7 7 SAFETY THERMOSTAT: Located at the front of the Floatation bath is a Red Cap. This is the reset button for the Safety Thermostat. This will trip if the Heated Well exceeds 80.0degC. This will trip if a failure of the Heater occurs, or if the operator removes the Glass tray for an extended period of time (Approximately 30minutes) without turning the Floatation bath off. To reset simply unscrew the Red cap and press the Red Button. The Thermostat will only reset if the temperature of the Heated Well has dropped below 60.0degC. An indication that this Safety thermostat has tripped is that the controller will turn off but the Mains switch is still illuminated. ELECTRICAL - POWER LEAD (at rear) A removable mains power lead with a three pin plug and right angle female IEC socket is supplied for connection between the male IEC socket located at the side of the bath, and a ten (10 Amp general Purpose Outlet) (G.P.O.) OPERATION WARNING: 1. To avoid injury do not use flammable solvents in this bath, as fire or explosion may result. This bath contains components that may ignite such materials. WARNING: 2. Do not introduce water into the well (it is not a bath) as it may result in component failure. OPERATION: 1. Locate the Bath as previously described in Location, plug the mains lead into the IEC socket at the back of the case and into the power supply. Turn on the power point. CAUTION: Ensure that the ventilation for the rear cooling fan are not obstructed. 2. Place the glass tray into the Heater Well and carefully fill with water. Place the Stainless Steel lid on the Glass tray. Warning: Contact with hot fluid of the bath may result in personal injury. Ensure appropriate protective equipment and procedures are applied at all times. 3. Turn on the main switch on the control panel. The switch is illuminated so you will know when it is on. The temperature will go through a short warm up period where all segments of the display will be on, before indicating the set temperature (SV) on the lower display and incubator temperature (PV) on the top display.

8 8 4. The Omron E5CC is a microprocessor based instrument that has been factory configured for range, sensor type, and engineering parameters for optimum control. Limited access to the control parameters is available. The operator can alter the temperature set point and has access to a parameter used for calibration purposes. 5. TO CHANGE THE SET TEMPERATURE: Use the button to move the cursor, the digit will flash indicating that it can be changed. Use the or arrows to change the temperature. When the desired temperature is set leave for a few seconds and the digits will stop flashing to confirm entry. Operating above 55.0degC: When operating at temperatures above 55.0degC it important to Stage the Temperature increase. It is advised to first let the Floatation bath operate at 55.0degC for at least 30minutes before changing to the required value above 55.0degC. This will limit nuisance tripping of the Over Temperature safety Thermostat. 6. OVER TEMP ALARM: The temperature control has been configured with automatic over temperature alarm. In case of a malfunction the alarm will turn off all forms of heating when the bath temperature is more than 2.0ºC above the set temperature. In this instance the controller will display ALM1.

9 9 SENSOR CORRECTION: There are a number of factors that will affect the accuracy of the temperature displayed in relation to the actual temperature inside the Glass Tray, these include the following: Ambient Temperature Level of water in the Glass tray Location of the sensor in the Glass Tray Whether the Stainless Steel Lid is on or off. Because of the above factors there may be an error between the temperature displayed and the temperature measured at the middle of the bath. For this reason the Omron temperature control has a parameter that can be used to correct the temperature displayed. This sensor correction parameter is displayed as. When checking calibration error in the middle of the Bath it is important that the water level in the Glass Tray is at least 75%full and that the Stainless Steel lid is on the tray. If the Stainless Steel lid is not in place water evaporation occurs which has a cooling effect, this cooling effect can show errors of up to 15.0degC In simple terms this parameter adds or subtracts a correction value to the displayed temperature to make it read the correct temperature. The calibration parameter can be accessed as follows: Prior to any calibration of the temperature display ensure that the equipment used to measure the incubator temperature has a current certificate of calibration to a traceable source, and that you are confident that it is accurate. Press the page button to access the sensor correction parameter. Use the up or down arrow to enter the sensor correction value. Allow the digit to stop flashing and the screen will display the adjusted value. In the example above the incubator temperature displayed (PV) is 37ºC. If a certified reference instrument measured 36ºC we would need to correct the temperature by -1.0ºC (note that the sensor correction parameter is accurate to 1 decimal place).
