Introduction
Thank you for your purchase of the YELLOW JACKET® YJACK® Series of Bluetooth® Sensing devices. The YJACK® series of devices are the evolution in creating an interconnected and efficient work environment allowing service technicians to work more quickly and precisely in the ever growing and complicated HVAC/R industry.
Take a moment to familiarize yourself with your new device(s). You will notice that all YJACK® devices feature a simple on/off button to power cycle the device, a quick-coupler for system attachment and/or a mounting magnet for strategic placement on surrounding metallic surfaces, and flexible connections to aid in the proper positioning of the device within your workspace. Each YJACK® product is powered by (2) AAA batteries housed beneath the removable battery door on the back of the device. The procedure to replace the product batteries is the same across all YJACK® devices and will be covered in more detail later.
All YJACK® products include an integrated Electronic Paper Display (EPD) or a status indication LED adjacent to the power button which can provide feedback as to the device’s current mode of operation. During normal operation, the status indicator LED will flash yellow once every two seconds to indicate that a measurement has been transmitted via Bluetooth®.
Unlike other Bluetooth® devices, YJACK® devices do not require “pairing” or an established connection between one another or the user’s smart device to transmit and receive information. Simply power the device on and it will immediately begin broadcasting data to other available devices within the broadcast range.
YJACK® tools may be used individually or together, broadcasting up to (6) unique measurements to one P51-870 TITAN® or TITANMAX™ Digital Manifold (see firmware requirements) or an unlimited number of unique measurements to a smart device running the YJACK VIEW® smart application.

When using the YJACK PATH®, numeric LEDs 1-8 will illuminate to indicate the number of YJACK™, TITANMAX™ and P51-870 TITAN® devices within range.

Placing the Device on the System

YJACK® Temperature Clamp
Depress the clamp handle to open the clamp jaws and attach the clamp to the pipe surface where temperature measurements are desired. For best results, attach the clamp in an area where the clamp jaws have full engagement of the pipe surface. The clamp can be used on pipes up to 1.25 inches in diameter. Avoid clamping over areas of pipe that are coated or insulated as this may impact the accuracy of the system temperature reading. If there is a ferrous metal surface near the placement of the clamp, the magnet on the bottom of the radio module can be attached to the surface for a more secure connection.

YJACK® Temperature Strap
Utilize the flexible strap to tightly secure the strap clamp to the pipe surface where temperature measurements are desired. First, open one of the buckles and pull the strap out of the buckle so that it is only retained in the second buckle. Feed the strap around the pipe and back through the open buckle. Pull the strap tightly around the pipe and then close the buckle. The strap can be used on pipes up to 6 inches in diameter. For best results, attach the strap in an area where the strap body has full engagement of the pipe surface. Avoid attaching the strap over areas of pipe that are coated or insulated as this may impact the accuracy of the system temperature reading. If there is a ferrous metal surface near the placement of the clamp, the magnet on the bottom of the radio module can be attached to the surface for a more secure connection.

YJACK DEW® Psychrometer
Remove the black vinyl cap covering the sensing element. Form the flexible wand to the desired shape and place the sensing element within the ventilation system or wherever psychrometric data is desired. If there is a ferrous metal surface near the placement of the Dew, the magnet on the bottom of the radio module can be attached to the surface for a more secure connection.

YJACK PRESS® Wireless Pressure Gauge
Remove the red plug from the brass quick coupler nut. Make sure the pressure transducer has been zeroed (this will be covered in more detail later) and attach the device directly to the system low-side or high-side service port. A 5/16” adapter (19121 straight or 19221 90 degree) can be used for systems with 5/16” connections. The integrated charging port on the back of the device can be connected to a charging hose for adjustment of system charge while continuing to monitor system pressure.

YJACK VAC® Wireless Vacuum Gauge
Remove the red plug from the brass quick coupler nut. Then the device can be attached directly to the side port of a core removal tool or to a system service port. A 5/16” adapter (19121 straight or 19221 90 degree) can be used for systems with 5/16” connections. For the most accurate system vacuum readings and to avoid contamination of the sensor, it is not recommended to connect the vacuum gauge directly to the vacuum pump.

YJACK AMP® Wireless Current Probe
Depress the clamp lever and place the CT around the hot or neutral wire where AC current is to be measured. Make sure the clamp jaws are fully closed for best accuracy. If there is a ferrous metal surface near the placement of the clamp, the magnet on the bottom of the radio module can be attached to the surface for a more secure connection.

YJACK MANO® Wireless Dual Port Manometer
Make sure that the supply and return pressures have been zeroed (this will be covered in more detail later). For static pressure measurements in ducting, drill 3/8” holes where the static pressure tips are to be placed. Insert the static pressure tips into the ductwork so that the tips are pointing towards the direction of airflow and use the provided tubing to connect the corresponding pressure tips to the supply and return pressure ports on the device. For gas pressure measurements, use the appropriate gas manifold fitting and use the provided tubing to connect the fitting to the corresponding pressure port on the device.

YJACK FLOW™ Wireless Anemometer
Remove the black vinyl cap covering the sensing element. Adjust the fixed wand to the desired depth to insert into duct and place the sensing element within the ventilation system with the arrow in the direction of the airflow. If the duct is a ferrous metal surface, the mounting adapter can be attached to the surface for a more secure connection.

YJACK PATH®
Although the YJACK PATH® is not placed directly on the system, the location of the device can impact its effectiveness in repeating the Bluetooth® signals from the other YJACK® devices. Be mindful of the environment in which readings are being taken. If there are obstructions, such as walls, paneling, or other equipment between the YJACK® devices and the P51-870 TITAN® or smart device running the YJACK VIEW® app, placing the YJACK PATH® in an area that has direct line-of-sight of the Bluetooth® devices often provides the best results and longest communication ranges. Also keep in mind that there could be obstructions and interference caused by signals not visible. If you believe that you may be experiencing signal interferences, move the YJACK PATH® to a different location until the Bluetooth® signal improves. If there is a ferrous metal surface near the placement of the YJACK PATH®, the magnet on the bottom of the radio module can be attached to the surface for a more secure connection.

Status LED: What Does it Mean?

When powering on the YJACK® device, hold the power button until the status LED illuminates solid yellow, then release the power button. Once powered on, the LED will flash every time the YJACK® devices readings are broadcast, every 2 seconds. When the battery level reaches 10%, the LED will flash red to indicate the low battery condition. When powering off the device, the LED stays red until the power button is released and the device is powered down.

Troubleshooting & FAQs

• Q: Why am I losing my Bluetooth® connection when I am within 400’ of the YJACK® device(s)?
  A: With any radio technology, when you start to add obstructions between the transmitter and the receiver, the ultimate range may decrease as different objects interfere with the radio signal in different ways. The more obstructions you add between YJACK® device and either the P51-870 TITAN® or the smart device running the YJACK VIEW® app, the weaker the signal may become after it has passed through or around the obstacles. This could ultimately lead to a shorter maximum range, but this can be improved by using the YJACK PATH® signal repeater device. All YJACK® devices, including the YJACK PATH®, utilize a Bluetooth® 4.2 compliant low energy radio to ensure the best possible range, however each situation will be slightly different depending on the environment/ surroundings you are working within. The YJACK PATH™ can be positioned to get around obstructions and up to 6 YJACK PATH® devices can be used simultaneously to maximize the connection range, even in environments with multiple obstructions.

• Q: Why doesn’t my TITANMAX™ show up on the list of available devices within the YJACK VIEW® app?
  A: The app must be version 5.0 or higher.

• Q: Why doesn’t my P51-870 TITAN® show up on the list of available devices within the YJACK VIEW® app?
  A: The radio inside the P51-870 TITAN® must be programmed with radio firmware version 2.01 or higher. This firmware version includes critical updates for communication with the YJACK VIEW® app. The firmware can be updated over-the- air through a Bluetooth® connection to a Windows or MacOS device.

• Q: Why are the YJACK® devices not showing up on my TITANMAX™?
  A: Only devices required for providing data to the sessions ion the TITANMAX™ will be displayed in the available devices session.

• Q: Why are the YJACK® devices not showing up on my P51-870 TITAN®?
  A: The circuit board inside the P51-870 TITAN® must be programmed with USB firmware version 2.01 or higher to recognize the YJACK® series of devices. If the P51-870 TITAN® firmware version that is displayed during power up is 1.40 or lower, the firmware must be updated through a USB connection to either a Windows or MacOS device.
