Quick Start

To operate the BluVac as a basic vacuum gauge:

  1. 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.

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 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 Range| Vacuum Pressure Reading| Resolution
---|---|---|---
Pascals (Pa)| 0- 3,333.1| 1,000.0 – 3,333.1| 0.1 Pa
0-999.99| 0.01 Pa
Millibar (mBar)| 0- 33.331| 10000 – 33.331| 0.001 mBar
0-9.9999| 0.0001 mBar
Millitorr (mTorr)| 0 – 25,000| 10,000 – 25,000| 1 mTorr
0 – 9,999.9| 0.1 mTorr
mmHg (mmHg)| 0 – 25.000| 10000 – 25.000| 0.001 mmHq
0 – 9.9999| 0.0001 mmHq
Microns (Microns)| 0 – 25,000| 10,000 – 25,000| 1 Micron
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 – AT M| 10-ATM

10| 10-20| 1-2| 0.01 – 0.02| 10-20| 0.01 – 0.02

Backlight

To activate the Backlight temporarily, press once. The indicator on the display will flash , and the backlight will turn off automatically after 1 minute. To activate the Backlight permanently, press again. The indicator on the display will show solid. Turn off the backlight by pressing repeatedly until the indicator turns off. During Sleep Mode, the backlight will turn off to help conserve battery power, but will turn on again automatically upon resumption of normal operation if it was previously set in the permanent-on mode.

Sound

The BluVac has an internal speaker that will emit a beep for each valid key press, and also functions as an alarm in the Programming and Calibration modes (see corresponding sections below). It will also beep every 5 minutes in Sleep Mode. For silent operation, the sound can be muted by pressing and holding the key. The alarm is not affected by the mute status. The indicator on the LCD display indicates that the sound is on (not muted).

Alternate Numeric Display

The BluVac has an Alternate Numeric Display that can indicate Vacuum Leak Rate, Ambient Temperature, or Programming Time/Progress. Please refer to the “Programming” section below for programming instructions. During normal operation, the Alternate Numeric Display may show either Vacuum Leak Rate or Sensor Temperature. Select the display mode by pressing the key until either LEAK RATE or TEMP illuminates on the display.

Vacuum Leak Rate Indicator

The Vacuum Leak Rate Indicator displays the rate of change of vacuum per second in the selected units when the LEAK RATE indicator is illuminated. The reading is positive for increasing pressure and negative of decreasing pressure. The Leak Rate Indicator is useful for determining the size of a vacuum leak, if one exists. Under high-pressure conditions, the leak rate indicator shows.

Ambient Temperature Indicator

Internally, the BluVac 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 TEMP indicator is illuminated. The accuracy of the temperature sensor is 0.2°F or 0.1 °C. The temperature display units can be toggled between Fahrenheit and Celsius by pressing and holding the key while in the temperature display mode.

Swivel Hook

The BluVac’s removable stainless steel swivel hook enables hanging of the gauge and will allow it to swivel freely in any direction. The gauge may be operated with or without the hook attached. When fastening the hook to the gauge, turn it finger tight only. Use of a tool to tighten the hook may result in damage to the BluVac case.

Programming

The programming feature of the BluVac allows for unattended evacuation of large systems, and will sound an audible/visual alarm when the evacuation program has been completed. The program consists of both a target pressure (vacuum level) and a time period through which the system must remain at or below that pressure. There are 16 possible target pressures, depending upon the units displayed, as shown in the table below:

Units

Microns| Pascal| Millibar| Millitorr| mmH

  6. While in the Run Mode, the gauge may sleep after 5 minutes of high pressure. The gauge will wake and continue the program normally once the pressure drops below 25,000 Microns. The gauge may be manually wakened from sleep by pressing any key. In the Run Mode, the Auto Power-Off feature is disabled.

NOTE: The units cannot be changed while in the Run Mode. Also, the Leak Rate and Ambient Temperature Indicators are disabled.

Maintenance

The BluVac 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.

Cleaning the Vacuum Sensor

If the vacuum sensor becomes contaminated with oil (as indicated by the Oil Sensor), carefully follow this procedure:

  1. Turn the BluVac power off.
  2. Shake the gauge to remove any large quantities of oil from the sensor.
  3. Apply a few drops of rubbing alcohol inside the sensor vacuum port. (DO NOT INSERT ANY OBJECT INTO THE PORT, AS THIS WILL PERMANENTLY DAMAGE THE SENSOR).
  4. Place your finger over the port and shake for a few moments.
  5. Remove your finger and shake out the alcohol.
  6. Repeat steps (3) – (5) at least three times.
  7. Allow the sensor to air dry over at least an hour, or pull a vacuum on the sensor to dry it more quickly (a few seconds).
  8. Replace the battery and turn on the gauge. The Oil Indicator should be off. If it is still on, repeat the cleaning procedure.
  9. If full accuracy is desired, perform a calibration cycle as detailed in the Calibration section below.

NOTE: It is important to remove all alcohol vapors from the sensor, either through air-drying or via vacuum. Any remaining vapors will cause an incorrect vacuum reading.

Calibration Test

The BluVac 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 is calibrated to factory specifications. Test the calibration as follows:

  1. Turn the BluVac power off.
  2. Important: Expose the BluVac to atmospheric pressure.
  3. Press and hold (do not release) the key for about 5 seconds.
  4. The display will show if the instrument is calibrated properly.
  5. The display will show if the instrument requires calibration. Please see the Calibration section below.

Calibration

If the Calibration Test indicates recalibration is required , the gauge may be recalibrated. Unlike any other vacuum gauge, the BluVac can be easily recalibrated to factory specifications without any special equipment, with the following procedure

  1. For best results, clean the sensor with alcohol prior to calibration. Ensure the sensor is completely dry before proceeding.

  2. Turn the BluVac power off. If necessary, install a fully charged battery into the gauge.

  3. Place the dust cap over the vacuum fitting.

  4. Hold Function Icon while pressing . As soon as the power turns on, release both buttons and then
    press Function Icon quickly at least three times. The CAL indicator should illuminate, and should show on the Main Numeric Display. If not, turn the power off again and repeat.

  5. Place the BluVac in a clear Ziploc (resealable zipper storage) bag, press out any extra air, and seal.

  6. Place the bagged BluVac into a freezer with a temperature of less than -5°C (23°F).

  7. Allow the BluVac to cool to below -2°C (28.4°F). At this point, the alarm will sound and the display will change to .

  8. Remove from freezer and press any key to silence the alarm.

  9. Place the BluVac undisturbed in an area with a room temperature of at least 23°C (73.4°F) but no greater than 30°C (86°F).

  10. Allow the BluVac to warm to 20°C (68°F). At this point, the alarm will sound, and will show on the display.

  11. Press any key to silence the alarm. The BluVac is now calibrated to factory specifications.

Note: For accurate calibration, it is necessary to allow the BluVac to warm slowly. Attempting to accelerate the warming by using a heat source will not provide satisfactory results. During the cooling/warming process, the temperature will be indicated on the Alternate Numeric Display in degrees Celsius. The calibration process may be canceled at any time by turning off the BluVac or by pressing and holding Function Icon . The previous calibration will be unchanged.

Restoring Factory Calibration

The original factory calibration can be restored at any time by the following procedure

  1. Turn the BluVac power off.
  2. Hold Function Icon while pressing . As soon as the power turns on, release both buttons and then press Function Icon quickly at least three times. The CAL indicator should illuminate, and should show on the Main Numeric Display. If not, turn the power off again and repeat.
  3. Press five times followed by Function Icon .
    The gauge will beep 5 times and return to normal operation. The BluVac is now reset to the original factory calibration.

Low Temperature Operation

The BluVac 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.

Frequently Asked Question

Q. How often must I calibrate the BluVa

A. Calibration of the BluVac 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. Can I use the BluVac to check the proper operation of my vacuum pump

A. Yes. Attach the BluVac directly to the pump with a short hose or coupler. Turn the pump on, open the blank-off valve, and close the ballast. A good pump with clean and dry oil will typically pull very quickly to less than 100 microns (generally around 25 microns for a two-stage pump). Always close the blank-off valve and/or disconnect the BluVac prior to turning off the pump so as to avoid oil contamination of the sensor.

Q. The BluVac does not indicate acceptably low pressure when I test my

pump.

A. Ensure the pump oil is clean and dry (it should be completely clear when viewed through the pump’s sight glass). Replace the oil. Ensure the pump ballast is completely closed and the blank-off valve is completely open, and all fittings are tight and seals are not damaged. If low pressure is still not achieved, the pump may be damaged or worn.

Q. I’ve attached the BluVac directly to my pump with a short hose or

coupler. As soon as I blank off the pump, the indicated pressure rises rapidly. Is the BluVac sensor leaking?

A. No. There will always be molecular-sized leaks, outgassing, and/or permeation in any hose or fitting, and the pump’s blank-off valve may not be entirely gas tight. The indicated pressure will rise due to the small internal volume of the hose or coupler.

Q. What is the recommended method for attaching the BluVac for evacuation

service?

A. Ideally, the BluVac should be as close to the internals of the system under evacuation, and as far from the vacuum pump as possible. Attaching the BluVac to the auxiliary port of a vacuum-rated core removal tool (CRT) connected directly to a service port is the best method. The ball-valve of the CRT can be closed to completely isolate the system from the pump and hoses, thereby allowing for an accurate rise-time test at the completion of evacuation. Additionally, removing the Schrader core(s) via the CRT and using large diameter hoses will greatly speed the evacuation process.

Q. I accidentally exposed the BluVac to high-pressure refrigerant. Did I

damage the BluVac?

A. No. The BluVac sensor is rated to 500 PSI overpressure, and can be directly exposed to gas/liquid refrigerant. At worst, the sensor may be exposed to oil, in which case the oil indicator will activate and cleaning/calibration may be required.

Q. I removed the BluVac from the system under vacuum, but the indicated

pressure rises slowly and/or the gauge does not return to Hi-P. Is the BluVac 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. 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. If the leak rate is unstable (bouncing between different numbers), this usually indicates liquid water boiling off inside the system. Since the resolution of the BluVac is so high, it may be difficult to achieve a zero leak-rate. This is not a problem as long as the system meets the manufacturer’s recommended vacuum rise-time performance.

Q. Why does the ambient temperature indicator show a different temperature

than my room thermometer?

A. The ambient temperature indicator actually measures the temperature of the metal sensor housing and the gas contained within the sensor. This temperature may be a few degrees different than room temperature. The temperature sensor itself is inherently accurate within 0.2°F (0.1°C) and requires no calibration.

Q. My BluVac reads a different pressure than my other vacuum gauge from

another manufacture. Which gauge is correct?

A. Unlike all other micron gauges, the BluVac’s accuracy is independent of temperature and pressure. Therefore, you can be confident that the BluVac’s reading is correct. Other gauges are calibrated at a specific temperature and pressure (i.e. 500 microns and 77°F (25°C)). The accuracy of those gauges is necessarily derated when operated at pressures and temperatures different than the calibration values.

Q. I am still having problems using the BluVac and/or understanding the

readings it is giving me. What should I do?

A. Please, contact us! Use our website at www.accutools.com or call us at 954-227-0781 between 9:00AM and 5:30PM EST. We will be happy to help.
