• If eyes come in contact with refrigerant, immediately flush with plenty of water.
  Seek medical attention immediately.

• If the battery indicator is red, charge the manifold before use. The sensors will not give accurate readings if the battery level is in red.

• Keep the manifold in a dry place. Do not allow moisture to enter the unit.

• Do not set manifold on top of an A/C system. This will result in incorrect temperature probe readings.

• Your digital manifold has been designed to eliminate the damaging effects of Electric Static Discharge ESD. If the unit is disrupted by ESD, it could affect the display and the unit may restart.

USING THE MANIFOLD
Note: Charge overnight before first use
TURNING ON AND USING THE TOUCH SCREEN
To turn the unit on, press the on/off button. The screen will flash white, go black, then the unit will start up. If the unit flashes white but does not turn on, you might need to press the button and hold it a little longer.
The manifold has a resistive touch screen. That means you can use any non- scratching item to press the buttons on the screen. Even a gloved finger. Use a light touch on the screen to activate a button.
Note: You might have to keep the button pressed a little longer than you are used to. The display will turn off (sleep) after four minutes. The manifold will keep running for 26
minutes after the screen turns off before turning off completely. To turn the display back on, touch anywhere on the screen or press the power button. To turn the manifold off, press the power button while the screen is on. On the left (your left when facing the screen), the blue side of the manifold is for the HVAC unit’s compressor suction or low-pressure side. The right, red side is for the compressor discharge or high-side of the unit.

CHECKING THE PRESSURES AND TEMPERATURES OF AN HVAC UNIT
Make sure the valves on the manifold are closed. Attach a blue hose to the left fitting (your left when facing the screen) and a red hose to the right fitting, using the opposite end of the hose from the hose’s valve or check valve. Attach the valve end of the blue hose to the suction side of the HVAC unit and the valve end of the red hose to the compressor outlet side. The manifold should show the pressure inside the unit.

SATURATED PRESSURES, SUPERHEAT AND SUBCOOL
For the manifold to calculate the refrigerant’s saturated pressure it has to be set to the refrigerant in the HVAC unit. To set the refrigerant, see “Refrigerants Screen” below.
The manifold will calculate superheat and subcool using the K type thermocouple clamps. Plug the clamp needed into the manifold. For superheat, use the left port. If you need to subcool, plug the clamp into the right port. You can use both ports at the same time if needed. The actual temperature at the clamp and the appropriate subcool/superheat will be calculated and displayed.

RECOVERY, VACUUM, AND CHARGING TWO-WAY MANIFOLDS
Use the center port to recover, vacuum and charge HVAC units. Attach hoses the same way as above. To recover the refrigerant in the system, connect the recovery machine to
the center port of the manifold using the recovery machine’s instructions. When ready to recover, open both valves on the manifold.
To vacuum the system, connect a vacuum pump to the center port of the manifold. There should be no pressure on the system. Turn on the vacuum gauge in the manifold. See
“Vacuum/Micron Sensor Gauge Screen” below. It is recommended to calibrate the vacuum sensor at atmospheric conditions before use. To do that, remove the cap or any hose on the center port. See “Vacuum Sensor Calibration Screen” for instructions. DO NOT do a deep vacuum calibration unless you have a highly accurate vacuum gauge for reference. With the vacuum pump connected, turn on the vacuum pump and open the valves. To charge a system, connect the center port of the manifold to a refrigerant cylinder on a scale. Purge the hose before charging the HVAC unit. Be sure to charge liquid refrigerant. Follow the HVAC unit’s instructions and the scale’s instructions to put a correct charge in the system.
4-WAY MANIFOLD S
4-way manifolds have the advantage of an extra fitting and two more valves than a 2-way manifold. This allows the system to be vacuumed and charged without changing any hose connections. Recovery can be done with the same setup as a 2-way manifold. Normally, the left-center fitting and black valve are used to connect to a recovery system and
vacuum pump.
The black valve can be closed to isolate the manifold and a vacuum pump can be attached to the left-center fitting. This will prevent any loss of vacuum created by the recovery
machine.
For vacuum and charging, a vacuum pump is connected to the left-center fitting and a source of refrigerant is connected to the right-center fitting. This way, the hose connected
to the refrigerant, the source can be vacuumed so purging of the refrigerant hose is not necessary.
Make sure the valve to the refrigerant tank is closed and there is no pressure in the HVAC unit. Open all the valves on the manifold and vacuum the system. Turn on the
vacuum gauge in the manifold. See “Vacuum/Micron Sensor Gauge Screen” below. It is recommended to calibrate the vacuum sensor under atmospheric conditions before use. To do that, make sure the manifold is at atmospheric pressure. See “Vacuum Sensor Calibration Screen” for instructions. DO NOT do a deep vacuum calibration unless you have a highly accurate vacuum gauge for reference.
After the unit has been evacuated, close the black valve on the manifold. The unit is now ready for charging. With the refrigerant tank on a scale, follow the HVAC unit’s instructions and the scale’s instructions to put a correct charge in the system.

ADDITIONAL MANIFOLD FEATURES

PRESSURE/VACUUM LEAK TESTING
The manifold has the capability to do a pressure leak-down test or a vacuum leak-up test. A leak test is used to check for gross leaks after a system repair without having to charge the system with refrigerant. For either one, press MENU then press LEAK TEST. To do a pressure leak test, pressurize the HVAC system with nitrogen or some other inert gas (never air) to the high-side running pressure. Select PRESSURE in the leak test screen. See “Pressure/Vacuum Leak Test Screen” for the specifics on setting the manifold to do the test. The manifold will show you the starting pressure, and the final pressure and calculate the difference for you.
To do a vacuum leak test, pull a high vacuum on the system. Press VACUUM on the leak test screen. See “Pressure/Vacuum Leak Test Screen” for the specifics on setting
the manifold to do the test. The manifold will show you the starting pressure, and the final pressure and calculate the difference for you.

DATA LOGGING
The manifold can record the values on the manifold’s main screen and then be downloaded to the Mastercool app. This is so you can see how the system is operating under normal usage for a long period of time. Go to MENU then DATA LOGGING to get to the data logging screen. See “Datalogging Screen” below for instructions on how to set the recording time and sampling frequency. The manifold does not need to be monitored during this process. It will remain on while recording, even though the screen will be blank. Touch the screen to see the recording progress. The unit remains on after it is finished recording. The data from the manifold can be downloaded using the Mastercool app. It will be in .csv format and can be imported to a spreadsheet program from there for analysis. Each data point will be numbered and time stamped.
