General Safety Information When installed, operated, and maintained according to the directions in this manual and common safety procedures, your Water Bath should provide safe and reliable temperature control. Please ensure that all individuals involved in the installation, operation, or maintenance of this Water Bath read this manual thoroughly prior to working with the unit.

This symbol marks chapters and sections of this instruction manual that are particularly relevant to safety. When attached to the unit, this symbol draws attention to the relevant section of the instruction manual.

This symbol indicates that hazardous voltages may be present.

This symbol marks information that is particularly important.

–  –  –

• Always connect the power cord on this Water Bath to a grounded (3-prong) power outlet. Make certain that the outlet is the same voltage and frequency as your unit.

–  –  –

• Never operate the Water Bath without bath fluid in the reservoir. Periodically check the reservoir to ensure that the liquid depth is within acceptable levels. Always refill the reservoir using the same bath fluid type that is already in the reservoir. Bath oil must not contain any water contaminants and should be preheated to the actual bath temperature before adding as there is an explosion hazard at high temperatures.

–  –  –

WARNING: Always allow the bath fluid to cool to ambient temperature before draining.

WARNING: It is the user’s responsibility to properly decontaminate the unit in the event hazardous materials are spilled on exterior or interior surfaces. Consult manufacturer if there is any doubt regarding the compatibility of decontamination or cleaning agents.

Regulatory Compliance & Testing CSA (60 Hz units) CAN/CSA C22.2 No. 0-M91 — General Requirement Canadian Electrical Code, Part II CAN/CSA C22.2 No. 1010.1-92 — Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use; Part I: General Requirements UL Std. No. 61010A-1 — Electrical Equipment for Laboratory Use, Part I: General Requirements IEC 61010-1 — Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use; Part I: General Requirements CE (50 Hz units) EC Low Voltage Directive 2006/95/EC EC Electromagnetic Compatibility Directive 2004/108/EC IEC 61010-1-2001 IEC 61010-2-2001 IEC 61326:2005 / EN 61326 : 2006

Your water bath is shipped in a special carton. Retain the carton and all packing materials until the unit is completely assembled and working properly. Set up and run the unit immediately to confirm proper operation. Beyond one week, your unit may be warranty repaired, but not replaced. If the unit is damaged or does not operate properly, contact the transportation company, file a damage claim, then contact the company where your unit was purchased.

WARNING: Keep unit upright when moving. Be sure to follow your company’s procedures and practices regarding the safe lifting and relocation of heavy objects.

Contents

The items included with your Water Bath are:

Water Bath • Gabled Reservoir Cover Assembly • Sample Tray • Operator’s Manual • Power Cord • Controls

–  –  –

General Site Requirements Locate your Water Bath on a level surface in an area that is free from drafts and wide ambient temperature variations, such as near heater or air conditioning vents. Do not place it where there are corrosive fumes, excessive moisture, or in excessively dusty areas.

Avoid voltage drops by using properly grounded power outlets wired with 14 gauge or larger diameter wire and, if possible, be close to the power distribution panel. The use of extension cords is not recommended; this will reduce the potential for problems caused by low line voltage.

Adding Liquid to the Bath Reservoir

WARNING: Read the safety data sheet for the bath fluid being used carefully before filling reservoir.

WARNING: See Technical Information in the rear of this manual for a list of compatible liquids.

WARNING: If the proper fluid level is not maintained, the unit could possibly be damaged (fluid level too low) or the bath may overflow (fluid level too high).





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

Fill bath so that liquid level is approximately one inch (2.54 cm) from top when samples are placed in bath.

To ensure accurate reading of temperature, the fluid level should not be less than 2 inches (5.08 cm) from the bottom of the unit. Operation of the bath without fluid will not damage the heater, but will cause permanent discoloration of the tank and will not provide accurate temperature information.

Distilled water is preferred for temperatures from 50° to 194°F (10° to 90°C). A variety of fluids can be used with the bath depending on the application. The fluid must be compatible with 300 series stainless steel. See Technical Information, Reservoir Fluids in the rear of this manual for a list of compatible fluids.

If using water, a few drops of polyclean Algaecide (part number 004-300040) should be used to help prevent algae formation.

WARNING: Always drain all fluid from the reservoir before moving or lifting your Water Bath. Be sure to follow your organization’s procedures and practices regarding the safe lifting and relocation of heavy objects.

–  –  –

Electrical Power WARNING: The Water Bath’s power cord must be connected to a properly grounded electrical receptacle. Make certain that this electrical outlet is the same voltage and frequency as your Water Bath. The correct voltage and frequency for your Water Bath are indicated on the identification label on the rear of the unit.

–  –  –

Insert female end of included IEC line cord into the IEC electrical outlet on rear of the water bath. Insert the male end of the line cord into a properly grounded wall outlet.

Once the unit is plugged in, will be displayed on the controller, indicating the unit is in stand-by mode.

The unit will stay in stand-by mode until powered ON by pressing the Power Button on the front control panel.

–  –  –

Safety Set Temperature This is a “Do Not Exceed” temperature setting for your Water Bath and is the temperature at which the heater will be turned OFF should the liquid level in the bath drop too low or the Water Bath malfunctions.

It is normally set about 5° higher than the desired operating temperature. The Safety Set temperature is

adjusted as follows:

1. Using a flat blade screwdriver, rotate the Safety Thermostat clockwise until it stops.

2. Turn power to the controller ON.

3. Set the bath to the desired safety set temperature.

4. Once the bath temperature has stabilized at the desired value, slowly rotate the Safety Thermostat counter-clockwise until the Safety Indicator light turns ON.

5. Slowly rotate the Safety Thermostat clockwise until the Safety Indicator light turns OFF.

Your bath is now ready for operation.

–  –  –

Normal Operation Turning Your Water Bath ON Place the Power Switch on the front panel in the ON position. If the actual bath temperature is lower than the set point temperature, the heating symbol will light.

Adjusting the Set Point Temperature Rotate the Temperature Set Dial until the indicator is at the desired set point temperature. Use an external thermometer to read the actual bath temperature; adjust the Temperature Set Dial as needed until the bath temperature stabilizes at the desired operating temperature.

–  –  –

Cleaning the Bath Thoroughly clean the bath before each use. Use only mild soap and water when cleaning. Do not use steel wool as damage to the unit may result. Non-steel scouring pads are acceptable.

The entire unit is housed in a tough, well-insulated stainless steel casing that is corrosion and chemical resistant.

Disassembling the Bath The following procedure should only be performed by a qualified service technician.

1. Unplug the bath from its power source.

2. Drain the bath of all fluid; remove the thermometer, clip, cover and sample tray.

3. Turn the bath upside down to expose the bottom. Remove the screws around the outer edge of the tank bottom plate.

4. Slide the bottom plate toward the front of the unit and lift off.

5. At this point, all the internal components are accessible for replacement.

Replacing Fuses

To check / replace fuses:

1. Unplug the power cord from the rear of the unit.

2. Locate and remove the fuse cover located on the top of the IEC power receptacle on the rear of the unit.

3. Check and replace fuses as needed; replace cover.

–  –  –

Stay within the fluid’s normal range for best temperature stability and low vaporization. At fluid’s high temperature

extreme:

• A fume hood may be required to prevent the buildup of vapors inside the room.

• Fluid lost from vapor will have to be frequently replenished.

• Caution must be taken to stay well below the fluid’s flashpoint.

–  –  –
