WARNING!!
• Wear Safety Glasses / Wear Gloves
• Keep the manifold in a dry place. Do not allow moisture to enter the unit.
• Do not vent refrigerant into the atmosphere.
• If eyes come in contact with refrigerant, immediately flush with plenty of water.
Seek medical attention immediately.
• STATIC DISCHARGE: Climates in some parts of the world are conducive to creating
static electric build up (ESD). Your digital manifold has been designed to eliminate
the damaging effects of ESD. In some extreme cases, ESD will be apparent on your
digital manifold by a lack of response or an inability to turn off the unit. In the rare
case that this occurs, simply disconnect the battery, wait 1 minute and reconnect
the battery. The digital manifold will "reboot" itself and operate normally once the
unit is turned on.
• Do not set manifold on top of an A/C system. This will result in incorrect
temperature probe readings.
• The display will show zero (0) whenever the measurement falls below the
following readings: 3 PSI, 0.2 Kg/cm, 0.2 BAR, 0.02 mPA or 6 in-Hg
• The digital manifold is normally shipped with vacuum and temperature sensors
that are calibrated with the companion manifold. In the event the other sensors are
provided by another source, please contact Mastercool Inc. for calibration
instructions.
BATTERY CARE & INSTALLATION
When the battery is connected to the unit but not in use it will last six months.
NOTE: In order to prolong the life of the 9V battery;
a.) keep auto-off function enabled
b.) if pressure, temperature or deep vacuum is being used for an extended period of
time turn the unit off and turn back on again when reading is required. (Allow
30-45 seconds for the correct reading to appear.)
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
