Section 1 Introduction

Congratulations on your new Fisher Scientific Isotemp Water Bath.
Isotemp Water Baths offer the versatility needed to handle virtually any clinical laboratory procedure – incubation, inactivation, agglutination -as well as most serological, pharmaceutical, biomedical, and industrial procedures.
These water baths are available with chamber capacities of 2, 5, 10, 20, and 28 liters. The 2 liter unit is available configured with either a standard or shallow chamber. Also, a dual chamber unit is available with 5 and 10 liter chambers, with independent controls for each. All units are available to operate from either 120 or 230 volts.
The baths work equally well with water or bath oil as the medium. All models offer the same temperature ranges: ambient to 60°C without the supplied cover, and ambient to 100°C with the cover in place (within physical limitations).
These baths are microprocessor controlled for precise temperatures and reliable, trouble-free operation. Dual thermostats – one controlling the set point temperature and the other operating as a safety – virtually eliminate the possibility of overheating. Although not designed to operate dry, the bath will not be damaged if it is allowed to run dry.
An energy-saving removable cover helps to reduce evaporation while helping to maintain a uniform, constant temperature. The cover also allows the water bath to reach higher temperatures. The hinged, see­ through gable cover features unique “fins” that keep hands away from hot vapors for easier, safer opening. The cover stays open at the 90° position or, because of its quick-attach hinge, can be lifted off completely to accommodate large glassware.
A plastic rim remains cool to the touch even when operating the bath at maximum temperature.
The unit features a power-on self-test of vital circuitry. This test will automatically be performed each time the unit is turned on. If problems are detected, the system will indicate a warning message on the display.
The calibration of the water bath can be adjusted to optimize its accuracy for the temperature that is used most often in your application. This can be accomplished through a simple procedure accessed from the front panel.
As a convenience, a drain pump is supplied with 10, 20, 28, and dual 5/10 liter models.
All controls are conveniently located on the front panel for easy access. To assure set point security, the temperature can only be changed by entering a specific set menu first. This ensures that the set point cannot be accidentally altered during extended or unattended operation.
To allow you to change the configuration of some units, and to permit easy servicing, your water bath provides front service access to the controller without having to empty the bath.
The water bath features corrosion resistant construction throughout to withstand the rigors of daily lab use.

Section 2 Safety Information

These instructions contain important operating and safety information.
The user must carefully read and understand these instructions before using the water bath.
Your unit has been designed to optimize function, reliability, safety, and ease of use. It is the user’s responsibility to install the bath in conformance with local electrical codes.
To avoid electrical shock, always:

• Connect the water bath to a properly grounded electrical outlet of the correct voltage and current handling capacity. Check the nameplate on the back of the unit for the voltage and current rating.
• Disconnect the unit from the power outlet prior to maintenance and servicing. Note that 230V units are double pole, neutral fusing.

To avoid personal injury:

• Do not use in the presence of flammable or combustible materials; fire or explosion may result. This device contains components which may ignite such materials.

• Do not remove or modify the grounded power plug. Use only properly grounded outlets to avoid a shock hazard. This unit is not rated for use in hazardous atmospheres.

• Do not continue to operate the bath if the temperature control fails (displays an “E” code or controls erratically) or the backup control fails (red safety light glows continuously when turned completely clockwise or fails to light when turned completely counterclockwise).

• Select a fluid that is not corrosive and is not flammable. The following fluids are not recommended and may damage the unit: Chlorides or bleach.
  Strong concentrations of any acid.
  Strong concentrations of any salt.
  Weak concentrations of hydrochloric acid, hydrofluoric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, or chromic acid.
  Weak salt solutions containing sodium chloride, calcium chloride, chromate or chromium compounds.
  High Purity water (deionized water, >lM ohm, etc.) Most photographic solutions.

• Do not use a flammable liquid. A fire hazard may result. This unit is not explosion proof Unit contains components which may ignite such materials.

• Use appropriate hand and eye protection when handling hazardous chemicals.

• The interior of the unit can reach temperatures that can cause burns.
  Avoid contact. The unit can remain hot without visual indication for some time after power is turned off

• If you will use the water bath with any liquid that will give off fumes, be sure to operate the water bath in a fume hood or with proper ventilation.

• Use the cover to reduce evaporation and to permit reaching higher temperatures.

• Hot liquids pose a burn hazard. Be careful not to reach into the bath when it contains hot liquids. Also be careful of steam rising from hot liquids.

• The unit is intended to be operated with liquid in the chamber.
  However, it will not be damaged if it temporarily runs dry unless ignited by melting samples/ plastic in the bath.

• Do not use in highly corrosive atmospheres; corrosive fumes and spillage may damage the unit and its internal components, creating a shock hazard.

• Fumes from acidic solutions cause corrosion of the stainless steel reservoir. Care should be taken to maintain a neutral pH at all times.

• Refer servicing to qualified personnel.

• Do not place containers directly on bottom of chamber. Bottom can get extremely hot if no liquid is in the chamber. Always use the diffuser tray.

Packing List

Note If there is shipping damage, keep entire shipment intact – retaining the carton and all packing material – and file a claim with the final carrier.
Usually the firm will send an investigator to ascertain liability . .

Assembly and Installation

Follow these steps to assemble and install the water bath before operation:

1. The location must:
   • Be indoors.
   • Provide an adequate source of power. Check the label on the back of the unit for voltage and current requirements.
   • Provide adequate clearance to insert samples.
   • Be level, fixed, and capable of supporting the weight of the unit when filled with liquid and samples.
   • Be free of drafts and wide ambient temperature variations such as near a heater or air conditioning vents.
   • Provide a fume hood if hazardous fumes are anticipated when using the water bath.
   • Be convenient to a sink for filling and draining the water bath.

2. Install the cover by inserting the hinge into the lip at the rear of the bath. Angle the cover up while pushing down to lock the hinge in place under the stainless steel tank lip. Remove the cover by lifting the lid and pushing the hinge towards the back to release it from under the tank lip. Covers on the 2 liter shallow, 5 liter, and 10 liter model baths can also be installed and removed by sliding the hinge into place under the rim and tank lips from either side.

3. Connect the line cord to a suitable grounded electrical outlet.

Repositioning the Control Panel
With 20 and 28 liter units, the control panel can be positioned on the side or the front of the unit in order to achieve the best use of available bench space. To change the position of the control panel, follow these steps:

1. Turn off the unit and disconnect from power source.

2. Allow to cool.

3. Remove thermometer and dip. Remove the cover.

4. Assuming that the water bath is empty, turn it over on a protected surface.

5. Remove two screws retaining the control panel and two screws retaining the blank panel.

6. Remove the blank panel.

7. Carefully move the control panel to the new location and reinstall.
   Note Do not disconnect internal wiring or sensors from control panel.

8.  Install the blank panel at the other location.

9. Return unit to location of use.

10. Reconnect power, turn on and test unit.
    Note This procedure applies to 20 and 28 liter units only.

Filling the Unit
Follow these steps to fill the unit in preparation for use:

1. Fill the water bath with tap water or oil so that the liquid level is approximately 1 1/2 inches (3/4 inch with 2 liter shallow model) from the top of the tank when full anticipated load is placed in bath.
2. If a thermometer is used, use the dip provided to hold the thermometer to the side of the bath. Slide the ****-ring on the thermometer to position the thermometer to the proper depth.
3. When dosing the cover, place the thermometer along the front edge. A notch along the front of the cover dears the thermometer and dip with the cover dosed.
4. For optimum results, the same fluid level should be maintained throughout the operating period.
5. If using water, algicide may be added to reduce algae formation. Follow the instructions supplied with the algicide.

Note If the bath has been used previously, the tank should be thoroughly deaned before refilling .

Controls and Indicators
All controls and indicators are located on the front panel for ease of operation.
Note The water bath, full of water (within 1- 1.5” of top of tank), with lid, is designed to reach 37°C in less than 60 minutes or 90°C in less than 180 minutes .

Section 5 Operation

Follow these procedures for the operation of the unit, including:

• Power up and initial indications.
• Setting the temperature units in °F or °C
• Setting the temperature setpoint.
• Setting the backup temperature.
• Calibrating the unit.
• Emptying and deaning the unit.

Power Up
Follow these steps to turn on the unit to prepare it for use:

1. Set the power switch to the ON position. The unit will go through a power-on self test that will take several seconds. During this time the display will show the unit’s capacity in liters.
2. When the unit has completed its self-test, it will maintain the bath at the last setpoint temperature. The Heat indicator wiU light when the unit is applying heat to the bath. This indicator will cycle on and off during normal operation.
3. When the display shows normal operation after completing the self­ test, continue by setting the temperature setpoint and backup temperature.
4. If the display shows any message after completing the self-test, do not use the unit. Refer to the Troubleshooting section to determine what is causing the message to appear on the display.

Setting Temperature Units to °F or °C
Note which indicator is lit to the left of the display, either F for Fahrenheit or C for Centigrade. If the desired indicator is lit, omit this procedure. To change the temperature units, follow this procedure:

1. Press Menu button so display shows _C_F. Press and hold the Set while simultaneously pressing the Increase or Decrease button until the display shows the desired temperature units, C for Centigrade or F for Fahrenheit.
2. Release all controls.Within a few seconds, the display will return to normal operation. The desired indicator (F or C) should be lit to the left of the display.

Setting the Temperature Setpoint

Follow these steps  to set the controller so that it maintains the desired temperature:

1. Turn Safety controller knob fully clockwise.

2. Press and hold the Set button to see the current setpoint. The Program indicator illuminates to show that this is the setpoint. If this setpoint is correct, there is no need to change the setting.
   The display will return to normal operation when the Set button is released, displaying the actual temperature.

3. To change the setpoint, press and hold the Set button while simultaneously pressing the Increase or Decrease button. The display shows the temperature setpoint as you change it. Release the Set button when the desired setting is achieved. The display will return to normal operation within a few seconds, displaying the actual temperature.

4. To check the setpoint without affecting normal operation, press the Set button at any time. To change the setpoint, repeat Step 3 above.

5. Set the Safety temperature according to the procedure below.

Note If Alarm Light comes on during normal cycling, turn backup controller knob slightly clockwise and monitor (if backup and digital controls overlap, the bath will have a wider temperature control band).

Setting the Safety Temperature
Follow these steps to set the water bath Safety temperature controller.

1. Set the Temperature set point 2 to 5° higher than desired temperature.Wait until bath temperature stabilizes as shown by displayed actual temperature.
2. Turn backup controller knob counterclockwise until Alarm light just comes on. Turn the knob clockwise slightly until the light goes off.
3. Set the digital set point 5° higher and verify the Safety is controlling 2 to 5° above desired set point.
4. Set the Temperature control down to desired temperature, allow the temperature to drift down, and verify the alarm light does not come on. If the light does come on, go back to Step 1, setting the Safety higher.

Calibrating the Unit
To check the accuracy of the unit, clip a certified thermometer, not supplied, to the side of the bath as described in the installation instructions. After allowing sufficient time for the temperature to stabilize, compare the thermometer reading to the actual temperature displayed on the unit. If the displayed temperature does not agree with the thermometer, calibrate the controller as follows:

1. Note the difference between the displayed temperature and the thermometer. For example: If the displayed temperature is 37 and the thermometer reads 36, the difference is -1, meaning that the display should read 1 lower than it now shows.
2. Press Menu button until display shows CAL.
3. Press and hold the Set button while simultaneously pressing the Increase or Decrease button to set the desired temperature offset.
   Release the Set button when the desired setting is achieved. The display will return to normal operation within a few seconds, displaying the actual temperature.

In the example above, set the display to read -1.
Note The temperature offset can be set up to a range of 5.5°C or 10.0°F.

Emptying and Cleaning the Unit
Please be advised that stainless steel can and will rust if not regularly deaned and properly maintained. It is recommended that the bath be deaned at least on a monthly basis for moderate or continuous use applications. Follow these steps to empty and dean the unit after using it:

1. Turn off power, unplug the unit, and allow to cool completely.
2. If you have a water bath of 2 or 5 liter capacity, pour the liquid from the unit into an appropriate disposal container.
3. If you have any other size water bath, allow the unit to cool and use the hand pump to empty the unit into an appropriate disposal container.
4. Clean the inside of the water bath with mild detergent (such as Joy dishwashing detergent) and warm water. Do not scrub any surface with steel wool. (Steel wool leaves small metal particles behind that will rust, causing the pan to look rusty). In instances where a heavy coating of residue has accumulated inside the tank or where there is evidence that corrosion is beginning, the use of a stainless steel cleaner (such as 3M Stainless Steel Cleaner and Polish) is recommended.
5. Rinse and wipe all tank surfaces with distilled water or equivalent.
6. Unit is now ready for next use.
