Battery installation
 Remove the battery compartment cover.
 Make sure to place the battery into the
compartment with the correct polarity.
 Replace battery cover.
Pressure adjustment for elevation
For an accurate reading, it is important to adjust the manifold for elevation and barometric pressure.
Follow these steps to set the unit for local elevation and barometric readings.
1. Press the POWER button to turn the unit ON.
2. Allow 10-15 seconds for unit to initialize. (You will see all characters and units countdown
99999,88888,77777... ) Once initialization is complete, only pressure and temperature readings will
appear.
3. Since the manifold reads absolute pressure it must be set for local elevation and barometric readings.
Press and hold the ENTER button for 10-15 seconds and release. Pressure readings will now be truly
zero.
NOTE: In some cases pressure reading may not be zero with the manifold disconnected from the
pressure or vacuum source. Press and hold the ENTER button for 10-15 seconds and release. Pressure
readings will now be zero.
WARNING! If the manifold is connected to a pressure or vacuum source and displays actual readings,
do not attempt to zero out the reading by pressing the enter button. This can offset the reading.
Setting refrigerant, pressure, temperature and auto-off
 Press the POWER button to turn the unit ON.
Wait for the unit to initialize [a refrigerant, pressure, temperature or vacuum will be displayed when
the unit is ready].
 Press the SELECT button to access the refrigerant menu.
 Press SELECT again to display refrigerant type.
Refrigerants: R11, R12, R13, R21, R22, R23, R32, R113, R114, R115, R116, R123, R124, R125, R134,
R134a, R141B, R142B, R143, R143A, R152A, R176, R218, R290, R401A, R401B, R401C, R402A,

 Press ENTER to confirm.
Next the Pressure Unit will display.
 Press the SELECT button to change the pressure unit. Press ENTER to confirm.
Next the Temperature Unit will display.
 Press the SELECT button to either °F or °C. Press ENTER to confirm .
Next Auto-Off will display.
 Press the SELECT button to disable Auto-Off [auto-off will clear from the display.] .
If the auto-off feature is displayed the manifold will shut down after 15 minutes, if no button is
pushed.
 Press the ON/OFF button to turn the unit back on and allow 15-20 seconds to initialize.
NOTE: It is recommended to keep the auto-off feature enabled to save the
life of the battery.
