BluVac+ Professional User’s Guide Battery Installation & Replacement 1. 2. 3. 4. 5. If installed, remove the protective boot. Remove the battery cover from the rear of the BluVac+ Pro by compressing tab at the base of the battery cover. If necessary, remove and detach old battery from battery clip. Attach battery clip to new battery and insert into battery compartment. Replace battery cover by aligning tab and snapping back into place. Reinstall the protective boot.
BluVac+ Professional User’s Guide Oil Sensor Prevent oil from being drawn into the Vacuum Sensor. For HVAC/R service, always recover refrigerant prior to attaching the gauge. If possible, always close the blank-off valve on the vacuum pump prior to turning the vacuum pump off. Over time, oil vapor and other materials may contaminate indicator the sensor. The BluVac+ Pro has a built in Oil Sensor that will detect this condition.
BluVac+ Professional User’s Guide The Vacuum Level Bar Graph has two modes: Evacuation Progress Indicator When the pressure is above 25,000 microns (when the display shows ), the Bar Graph indicates evacuation progress. The bars progressively drop as the pressure drops between ATM and 25,000 microns. Vacuum Level Indicator Below 25,000 microns, the Bar Graph allows for a quick visual determination of the vacuum level achieved.
BluVac+ Professional User’s Guide Ambient Temperature Indicator Internally, the BluVac+ Pro uses a very high accuracy temperature sensor to maintain proper calibration throughout the entire operating temperature range. This temperature is shown on the Alternate Numeric Display when the indicator is illuminated. The accuracy of the temperature sensor is 0.2°F or 0.1°C. Saturation Temperature Indicator The saturation temperature of water (i.e.
BluVac+ Professional User’s Guide Programming As a special feature, the BluVac+ Pro includes two related programs: the Evacuation Program and the Rise Time Testing (RTT) Program. The Evacuation Program allows for unattended evacuation of large systems, and will sound an audible/visual alarm when the evacuation procedure is complete, based upon both an Evacuation Target Pressure and Evacuation Target Time.

If the pressure exceeds the RTT Target Pressure before the RTT Target Time is achieved, the BluVac+ Pro will alarm and show to indicate that the test has failed. In either case, pressing any key will silence the alarm. In the case of a , the clock will continue counting for further manual analysis. This can be stopped by pressing the In the case of a , normal operation will immediately resume. key.
BluVac+ Professional User’s Guide Calibration Test The BluVac+ Pro should rarely require recalibration, though it may be necessary to know that your gauge is calibrated properly for full accuracy. The Calibration Test mode assures you that the BluVac+ Pro is calibrated to factory specifications. Test the calibration as follows: 1. 2. Power off the BluVac Pro+. Important: Expose the BluVac+ Pro to atmospheric pressure. 3. 4. 5. key for about 5 seconds.
BluVac+ Professional User’s Guide Low Temperature Operation The BluVac+ Pro can operate accurately at temperatures as low as 10°F (-12°C). While operating below freezing (32°F/0°C), the display update rate will slow from 3.5 readings every second to one reading every two seconds. For satisfactory battery life at low temperatures, a 9V Lithium battery is recommended. Troubleshooting or Under certain conditions, the display may read determine and fix the problem: Display Mode .
BluVac+ Professional User’s Guide Frequently Asked Questions Q. How often must I calibrate the BluVac+ Pro? A. Calibration of the BluVac+ Pro is only necessary when the Calibration Test indicates that calibration is required. Regardless, frequent cleaning and/or calibration will not adversely affect the long-term reliability of the instrument. For best results, ensure the sensor is clean and dry, and the dust cap is in place, prior to calibration. Q.
BluVac+ Professional User’s Guide Q. How do I use the leak rate indicator? A. The leak-rate indicator is especially useful for system diagnostics during a rise-time test. If the indicated leak rate is stable and constant, this usually indicates a physical vacuum leak. If the leak rate is stable, but decreases as the pressure rises, this usually indicates evaporating moisture or outgassing.
