SECTION 2 – EQUIPMENT OVERVIEW Congratulations! You have just purchased the latest technology in constant temperature circulators. Before using the equipment, familiarize yourself with key components of the product and thoroughly read this manual.
SECTION 3 -- INSTALLATION Unpacking Your unit has been packaged to avoid shipping damage. However, the unit should be fully inspected upon arrival before signing for receipt. If the package has visual damage, notes should be made on the freight bill and signed by the delivery company. In the event of concealed damage after the unit is uncrated, keep the carton and packaging material. Call the shipping company within 7 days of receipt, request inspection & retain a copy of the inspection report.
Connecting Electrical Power The unit requires an electrical connection that must be properly grounded. The power cord of this circulator is equipped with a grounded plug which mates with a standard grounded wall outlet. Operate the unit using only the power cord that has been supplied when purchased. Leakage current of this unit can exceed 3.5mA.
SECTION 4 – OPERATION External circulation begins immediately when power is turn on. With the circulator properly installed and the appropriate utilities connected, the power switch on the left side of the control bezel can be turned on. Within minutes, the temperature will begin to approach setpoint. The circulator keypad is designed to produce a simple, easy to understand user interface that is intuitive and user friendly.
Changing the Temperature Setpoint The circulator has an operating temperature range of -15.0°C to 90.0°C. The default is 20.0°C.
1) Press the 2) Press the key three times from the main menu, “AL.
SECTION 5 – CALIBRATION The temperature can be calibrated as necessary. CARON recommends an annual calibration check. Place the reference instrument’s temperature sensor in the tank or circulating loop at the desired control location. Before making a calibration adjustment, allow the circulator to stabilize. The calibration offset is adjustable from -10.0°C to 10.0°C. The default is 0.0°C.
SECTION 6 – ALARM Low Level Alarm The circulator is equipped with an alarm system that alerts the operator of a low fluid level condition. When more fluid is needed, an audible buzzer will sound and the red low level light on the control panel will illuminate. While in alarm mode, the circulator will not properly control fluid temperature. External circulation will continue. Add fluid per instructions in INSTALLATION section.
SECTION 7 – PREVENTATIVE MAINTENANCE The CARON circulator has been robustly designed to minimize performance problems. However, regular maintenance is very important for continuous trouble free operation. Recommended Daily Maintenance Checks Check the Temperature display versus setpoints. Check for and correct any alarm condition. Recommended Monthly Maintenance Checks Check condenser air intake filter on top of unit. If it is dirty, replace it with CARON part number FLTR306.
