Introduction
Thank you for choosing this Water Bath. It is designed to handle a wide range of laboratory procedures, including: incubation, inactivation, and agglutination as well as most pharmaceutical, serological, biomedical, and industrial procedures.
To ensure optimum temperature uniformity, your Water Bath features an energy efficient, large-area heater and thermostatic control. Its PID microprocessor control (Proportional Integral Derivative) system provides proportional heat control by anticipating the approach to your set point temperature and preventing overshoot. A redundant safety thermostat is standard on all models.
General Safety Information

Safety Recommendations
To prevent injury to personnel and/or damage to property, always follow your workplace’s safety procedures when operating this equipment. You should also comply with the following safety recommendations:
WARNING:
•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 with a damaged power cord.
•Always turn the Water Bath OFF and disconnect mains power before performing any maintenance or service.
WARNING:
•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.
•Use compatible bath fluids only.
•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.
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.

Unpacking Your Water Bath
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.

Installation and Startup
Your Water Bath is designed to be simple to setup and install. The only tools required are a flat-head screwdriver and a container for adding water or another suitable fluid to the bath reservoir.
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 10° to 90°C (50° to 194°F). 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.
WARNING: To avoid the potential for burns, allow the Water Bath to cool completely before cleaning or performing any maintenance.
