BluVac+ LTE 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+ LTE 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+ LTE User’s Guide Oil Sensor Prevent oil from being drawn into the Vacuum Sensor. For HVAC/R service, always recover refrigerant prior to attaching 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 the sensor. The BluVac+ LTE has a built in Oil Sensor that will detect this condition.
BluVac+ LTE User’s Guide “Analog” Vacuum Level Bar Graph 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+ LTE User’s Guide Wireless Operation Press and release to turn the Bluetooth radio on and off. When turned on, the icon will flash in the display. This is an indication that the radio is on and advertising (i.e. waiting for a connection from a mobile app). When a connection is made by a mobile app, the flashing). icon will illuminate solid (not For mobile application operating instructions, please refer to the instructions and help material included with the application.
BluVac+ LTE User’s Guide Maintenance The BluVac+ LTE should provide many years of service with no maintenance required. When not in use, the dust cap should remain in place over the sensor port. Clean the plastic enclosure with a damp (not wet) rag. Mild detergent is acceptable, but use no solvents. Take care not to expose the vacuum sensor to oil. If the Oil Sensor (described above) indicates a contaminated sensor, follow the Sensor Cleaning Procedure below.
BluVac+ LTE User’s Guide Calibration If the Calibration Test indicates recalibration is required, the gauge may be recalibrated. Unlike any other vacuum gauge, the BluVac+ LTE can be easily recalibrated to factory specifications without any special equipment, with the following procedure: 1. 2. 3. For best results, clean the sensor with alcohol prior to calibration. Ensure the sensor is completely dry before proceeding. Turn the BluVac+ LTE power off.
BluVac+ LTE User’s Guide Troubleshooting Under certain conditions, the display may read determine and fix the problem: Display Mode Normal Operation or . Please use the table below to Possible Problem Sensor Contaminated Ambient Temperature too Low Solution Clean the Vacuum Sensor Turn the BluVac+ off, warm the vacuum port with your hand, turn the BluVac+ back on.
BluVac+ LTE User’s Guide Frequently Asked Questions Q. How often must I calibrate the BluVac+ LTE? A. Calibration of the BluVac+ LTE 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+ LTE User’s Guide Q. I removed the BluVac+ LTE from the system under vacuum, but the indicated pressure rises slowly and/or the gauge does not return to Hi-P. Is the BluVac+ LTE damaged? A. No. The slow rise in pressure is due to residual refrigerant gas captured in the sensor. Gently blowing air into the sensor to remove the residual gas will effect an immediate rise to Hi-P. Q. My BluVac+ LTE reads a different pressure than my other vacuum gauge from another manufacture. Which gauge is correct? A.
