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