This document serves as an operating manual for Anova Temperature Control Instruments, specifically Refrigerated and Heating Circulators from the A Series. It provides essential information for the safe and optimal use, installation, and maintenance of these devices.
Anova circulators are designed to precisely control the temperature of specific fluids within a bath tank. They are primarily used for temperature control of external systems in a closed-loop circuit. These instruments are not intended for direct temperature control, meaning that objects should not come into direct contact with the bath fluid. This includes food, tobacco, pharmaceutical, and other consumable organic products. For food preparation, items must be vacuum-sealed before being placed in the circulator to prevent direct contact with the bath fluid. The systems feature a pump connection for efficient fluid circulation, ensuring consistent temperature management.
The circulators are equipped with a user-friendly interface that includes an LCD with a touchpad and a control keypad for easy operation. Key indicators and a temperature display provide real-time feedback on the system's status. A safety dial temperature limiter is integrated to prevent overheating, enhancing operational safety. The bath opening allows for easy filling and access to the bath fluid.
For connectivity and control, the circulators include a power switch, power connector, and a fuse for electrical protection. An RS232 port is available for computer control, allowing for remote monitoring and programming. This feature enables users to interface the circulator with a PC using a DB9 Serial Cable Male to Female (straight-through configuration). The manual provides detailed instructions for setting up RS232 communication, including port settings (Baud Rate: 9600, Data Bits: 8, Parity: none, Stop bits: 1, Flow control: none).
A comprehensive set of RS232 commands is provided for various functions. Status commands like "help," "version," "status," "default," and "temp" allow users to retrieve information about the system, software version, current status, reset settings, and check the bath temperature. Control commands such as "start," "stop," and "clear" enable users to initiate, halt, or clear errors from the system. Setting commands like "set temp xxx.xx," "set highlimit xxx.xx," "set lowlimit xxx.xx," and "set pump speed" allow for precise adjustment of temperature, high/low temperature warnings, and pump speed. Corresponding "get" commands are available to retrieve current settings.
Safety is paramount, and the manual emphasizes several precautions. Users are advised to unpack and inspect the circulator for transport damage immediately upon receipt. For refrigerated systems, it is crucial to wait 24 hours before powering on to allow compressor oil to settle, ensuring maximum cooling capacity. Any damage must be reported to Anova and the carrier promptly to support insurance claims.
Installation guidelines include placing the system on an even surface to prevent spills and ensuring adequate air ventilation, with at least one foot of open space around the front and rear vents. The unit should not be installed near heat sources, outdoors, or exposed to direct sunlight. It is also important to ensure a low impedance power supply.
Regarding bath fluids, the manual provides specific recommendations for both cold and hot temperature ranges. For cold temperatures, ethanol or a water/glycol mixture (1:1) is recommended for 1°C to -20°C, and Dynalene for -20°C to -40°C. For hot temperatures, soft/decalcified water or distilled water is recommended for 1°C to 80°C, while mineral/silicone oils are suitable for 80°C to 200°C. Warnings are issued against using hard, ferrous, or chloric water due to calcification, corrosion, and pitting risks. Lab distilled and deionized water can also cause corrosion over long-term use in stainless steel. The manual stresses the importance of using only non-acidic and non-corrosive bath fluids and advises against highly viscous, creep-prone, or corrosive fluids. Users are urged to consult the safety data sheet of the bath fluid and pay attention to its flash point.
Filling procedures include taking care not to spill liquid into the circulator's interior, maintaining a maximum filling level of 1.5 inches below the rim, and never draining hot bath fluid.
System maintenance is crucial for prolonging the life and performance of the Anova circulators. General information includes always turning off the unit when not in operation and ensuring that electrical work is performed only by Anova-certified personnel.
Coolant maintenance involves regularly draining the reservoir, flushing the chiller with water (for water-soluble coolants) or surfactant and water (for oil-based coolants), and cleaning the bath tank and immersed parts with a mild surfactant like dish soap and a soft brush. Steel wool or bleach should be avoided as they can cause corrosion and pitting. The coolant should be replaced when visibly dirty, as old coolant can clog the pump and restrict system performance.
Cleaning the exhaust vent involves wiping it with a wet towel and removing any restrictions with compressed air. The air filter for the condenser should be removed from the front panel, cleaned under running water, and may require surfactants or detergents depending on air content.
For repairs, users are instructed to contact an Anova representative for a return authorization (RA) number. When transporting or returning the unit, it must stand upright, be marked with the RA number, and be carefully and adequately packed. Anova is not responsible for damages resulting from insufficient packing, and the entire unit must be shipped by freight.
The manual also outlines warranty provisions, emphasizing that restricting airflow, using inappropriate coolants (acid/base solutions or salts), or failing to comply with other requirements will void the manufacturer's warranty. The warranty covers defects in material and workmanship for one year or 5,000 hours of operation, whichever comes first, from the shipping date. Exclusions include damage from accident, misuse, improper installation, unauthorized repair, or failure to follow operating instructions. Glassware, including reference thermometers, is expressly excluded from the warranty.
