PRESSURIZED GASES AND FLUIDS ARE DANGEROUS. BEFORE
CONNECTING OR DISCONNECTING PRESSURE EQUIPMENT, SAFELY
RELEASE ALL THE PRESSURE.
ENSURE THAT THE SYSTEM IS BLED OF EXCESS AIR BEFORE
OPERATION. (IF THE ITEM UNDER TEST HAS A LARGE VOLUME,
PRE-FILL WITH THE PRESSURE FLUID TO ENSURE THAT TRAPPED
AIR IS KEPT TO A MINIMUM).
To prevent damage to the pressure station, do not let dirt get into
the pressure mechanism. Before connecting equipment, make
sure it is clean.
Ice in the pressure mechanism can cause damage. If the
temperature is less than 4°C (39°F), drain all water from the
instrument.
