Appion AV760 Digital Vacuum Gauge

Introduction

TO REDUCE THE RISK OF INJURY OR PRODUCT DAMAGE, READ OPERATION MANUAL PRIOR TO OPERATING PRODUCT.

AC/R system operating efficiency depends on proper evacuation. Proper evacuation depends on a reliable vacuum gauge capable of monitoring the entire evacuation process.
The AV760 accurately displays measurements from atmosphere (760,000 microns) all the way to deep vacuum (10 microns), so you can be sure your system is clean, dry, and tight.

Safety

Do not connect to systems under pressure.
Do not use leaky or damaged batteries.
Use only specified batteries and cleaning agents.
Battery operating temperatures may vary by manufacturer.
The batteries supplied with this unit are for storage and operating between 32°F – 104°F (0°- 40°C)
Dispose of batteries in accordance with any applicable local laws and regulations.
Do not dispose of the product or battery in a fire or heat above 100°C.

Do not insert any objects into the sensor ports of the sensor housing.
Doing so may permanently damage the sensors.

Button Configuration

Quick PRESS a button for the “Press” function.
HOLD a button for 2 seconds for the “Hold” function.
Quick press BOTH buttons for the “Both” function.

Using The AV760

CAUTION : Do NOT connect the AV760 to systems under high pressure. While the AV760 is designed to withstand accidental exposure to positive pressures, continued exposure may cause permanent damage.

Using the 45° Swivel Vacuum Connector (included), connect the AV760 to an available service port furthest from the vacuum pump.
Hand-tighten the connections to ensure a tight connection. Never tool tighten a knurled fitting.
Press the Power button to turn on the AV760. A countdown will display while the AV760 starts up and performs self testing.
Press and hold the units button for 2 seconds to cycle the displayed units (optional).

Tip : Connect to the side access port on a vacuum-rated Valve Core Removal Tool with the Vacuum Connector. Make sure the depressor side is attached to the Valve Core Removal Tool.
Tip : Make sure the AV760 is vertical, with the fitting pointed downward. This will help minimize contamination from any oil that may be pulled out of the system during evacuation.
Tip : Add the use of a secondary Valve Core Removal Tool or a Core Control Tool to isolate the gauge prior to introducing positive pressure.

Appion Central™ Bluetooth Operation

Note : Bluetooth communication requires a compatible device running the Appion Central™ App. Development of the Appion Central™ App is ongoing, and any information presented in this manual about the Appion Central™ App may not be up to date. Please visit AppionTools.com or your device’s App Store for the latest Appion Central™ App and additional information.

With the AV760 powered on, press and hold the Bluetooth button until the Bluetooth symbol appears on the AV760 screen.
In the Appion Central™ App, navigate to “My Devices” and connect to the AV760 as shown.
If the connection is lost due to exceeding the Bluetooth range, or due to loss of power, repeat Step 1, then “Reconnect” the AV760 through the Appion Central ™ App interface.

Note : Bluetooth range may vary due to obstructions or interference. The Appion Central™ App will indicate when communication is lost.
Note : The AV760 will continue to operate normally even if Bluetooth communication is lost.

General Maintenance & Care

The AV760 is a precision instrument that must be maintained to ensure proper function. The knurled fitting can be removed to enable easy inspection of the sensor housing components if you suspect the AV760 sensors are dirty and no longer reading correctly.

Remove the knurled fitting with o-ring and the oil catch filter from the sensor housing.
Do NOT remove the protective screen covering the sensors.
Inspect the knurled fitting and o-ring for damage or excessive wear. Replace the o-ring if damage is suspected. If the knurled fitting is damaged, contact Appion directly.
Inspect the fitting tip for debris buildup and ensure the ball check valve within the knurled fitting moves freely and is clear of obstructions by shaking the fitting and l listening for a rattling noise. If the fitting tip has debris buildup or the ball check valve is not moving freely, use quick-dry electronics cleaner to clean the fitting.
Inspect the oil catch filter for oil by blotting it on a clean paper towel. If any oil remnants appear, discard the oil catch filter and replace with a new one.
Apply a small amount of vacuum grease to the knurled fitting o-ring and hand-tighten the fitting onto the s sensor housing. NEVER tool-tighten a knurled fitting.
Connect the AV760 to a vacuum pump. Then, run the pump until the gauge display reads 100 microns or less.
If necessary, perform an isolation test to ensure the fittings and sensor housing are not leaking.

Advanced Cleaning

Please follow the General Maintenance and Care procedures outlined previously BEFORE attempting the advanced cleaning procedures.

Do not touch or insert any objects into the sensor ports. Doing so may permanently damage the sensors.

Remove the knurled fitting with o-ring, then the oil catch filter from the sensor housing.
Pour quick dry electronics cleaner into the sensor housing. Cover the sensor housing to trap the cleaner inside. Next, gently shake the gauge for 5-10 seconds.
Dump the remaining cleaner from the sensor housing and let the gauge sit right-side-up for 15 minutes.
Apply a small amount of vacuum grease to the o-ring on the knurled fitting. Then, reinstall a new oil catch filter and hand-tighten the knurled fitting onto the sensor housing. Never tool tighten a knurled fitting.
Connect the AV760 to a vacuum pump, and run the pump until the gauge reads 100 microns or less.
If necessary, perform an isolation test to ensure the fitting and sensor housing are not leaking.
