Install the battery as described in the “Battery Installation” section below. 2. Turn the power on by pressing . The display will show to indicate pressure greater than 25,000 Microns. 3. Select the desired units by repeatedly pressing . 4. Attach the BluVac to the system to be evacuated with a high quality vacuum hose. Start the vacuum pump. Read the vacuum level from the Main Display. 5. Turn the power off by pressing and holding . WARNING: To avoid damaging the BluVac, only hand-tighten sensor connection. If greater torque is required, support the sensor housing with a ¾” wrench. NOTE: To assist in the use of this gauge and the interpretation of vacuum information, please refer to the Frequently Asked Questions Section at the end of this guide. 4 BluVac User’s Guide Battery Installation & Replacement 1. Remove the battery cover from the rear of the BluVac by compressing tab at the base of the battery cover. 2. If necessary, remove and detach old battery from battery clip. 3. Attach battery clip to new battery and insert into battery compartment. Replace battery cover by aligning tab and snapping back into place. IMPORTANT: TO PREVENT DAMAGE FROM LEAKING BATTERIES, DO NOT LEAVE A DEAD BATTERY INSIDE THE BluVac. REMOVE BATTERY IF THE BluVac IS NOT TO BE USED FOR AN EXTENDED PERIOD OF TIME. Battery Level Indicator The battery level indicator shows the relative strength of the battery. Full power is indicated by four bars. As the battery is depleted, the number of bars displayed decreases, until no bars are left. At this point, it is necessary to replace the batteries (refer to the Battery Installation section above). If the battery power drops to the point where the BluVac can no longer function accurately, the alarm will beep 10 times and the power will turn off automatically. When the battery is replaced, and the BluVac is turned back on, the BluVac will resume operation with all previous setting intact. Hi-Pressure Indication If the sensed vacuum pressure exceeds 25,000 Microns (3333.1 Pa, 33.331 mBar, 25,000 mTorr, or 25.000 mmHg), the display will show . Sleep Mode Unlike other Digital Vacuum Gauges, the BluVac helps to conserve battery life through advanced power management. After 5 minutes of displaying , the BluVac will enter “Sleep Mode” in which the sensor and backlight are turned off, thus reducing the load on the battery and extending the battery life up to 300 hours or more. While in this mode, the display will show . Approximately every 35 seconds, the gauge will automatically check the pressure and exit Sleep Mode if the pressure is less than 25,000 Microns. The gauge can be manually brought out of Sleep Mode by pressing any key on the keypad. While in Sleep, the gauge will beep twice every 5 minutes to remind you that it is on. The BluVac will not sleep in the Set Mode or the Calibration Mode (see the corresponding sections below). Auto Power-Off After 1 hour in “Sleep Mode” the BluVac will automatically turn itself off to further conserve battery power. Oil Sensor It is necessary to 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 has a built in Oil Sensor that will detect this condition. If the OIL indicator on the display illuminates, this is an indication that the vacuum sensor has been contaminated and is no longer functioning accurately. If the sensor becomes completely saturated with oil to the extent that it cannot function properly at all, the message will show on the 5  BluVac User’s Guide display. Prior to further use of the BluVac, clean the sensor as describe in the “Cleaning the Vacuum Sensor” section below. Units Change the displayed units by pressing and releasing the key on the keypad. The appropriate units indicator on the LCD display will show Pa, mBar, mTorr, mmHg, or Microns depending on the units set. The units cannot be changed in the Set Mode or the Run Mode (see corresponding sections below). Range and Resolution The BluVac has a broad vacuum pressure measurement range, and the highest resolution of any gauge. The display range and resolution depends upon the units displayed and the vacuum pressure reading, according to the table below: Vacuum Vacuum Pressure Range Reading Resolution 1,000.0 — 3,333.1 0.1 Pa Pascals (Pa) 0 — 3,333.1 0 — 999.99 0.01 Pa 10.000 — 33.331 0.001 mBar Millibar (mBar) 0 — 33.331 0 — 9.9999 0.0001 mBar 10,000 — 25,000 1 mTorr Millitorr (mTorr) 0 — 25,000 0 — 9,999.9 0.1 mTorr 10.000 — 25.000 0.001 mmHg mmHg (mmHg) 0 — 25.000 0 — 9.9999 0.0001 mmHg 10,000 — 25,000 1 Micron Microns (Microns) 0 — 25,000 0 — 9,999.9 0.1 Micron “Analog” Vacuum Level Bar Graph The BluVac also displays a Vacuum Level Bar Graph allowing for a quick visual determination of the vacuum level achieved. Each bar corresponds to a vacuum pressure range depending on units according to the following table: Units Bar Value Microns Pa Millibar Millitorr mmHg 10K 10,000 — ATM 1,000 — ATM 10 — ATM 10,000 — ATM 10 — ATM 5K 5,000 — 10,000 500 — 1,000 5 — 10 5,000 — 10,000 5 — 10 2K 2,000 — 5,000 200 — 500 2—5 2,000 — 5,000 2—5 1K 1,000 — 2,000 100 — 200 1—2 1,000 — 2,000 1—2 500 500 — 1,000 50 — 100 0.5 — 1 500 — 1,000 0.5 — 1 200 200 — 500 20 — 50 0.2 — 0.5 200 — 500 0.2 — 0.5 100 100 — 200 10 — 20 0.1 — 0.2 100 — 200 0.1 — 0.2 50 50 — 100 5 — 10 0.05 — 0.1 50 — 100 0.05 — 0.1 20 20 — 50 2—5 0.02 — 0.05 20…
