WARNING
CAREFULLY READ THESE INSTRUCTIONS BEFORE
INSTALLING THE PRESSURE DIFFERENTIAL KIT.
MAKE SURE THAT THE COMPONENT OR PIPING IS
DEPRESSURIZED BEFORE INSTALLING THE PRESSURE
DIFFERENTIAL KIT.
Completely depressurize the piping and component that the kit is to be
installed on.
Figure 1 shows a typical assembly/installation of the PD-7 series pressure
differential gauge on a VAN AIR VME series Mist Eleminator.
Mount the PD-7 on the mounting bracket. Use the fasteners provided with
the kit. Mount the kit to the desired surface. The VME vessel has a angle
bracket on the front for the installation of the PD-7 and bracket.
IMPORTANT
To ensure an accurate reading, make sure that both tubing lines
to the PD-7 are equal in length. Use as few as possible bends in
the tubing lines.
Install the necessary tubing from the inlet side of the vessel or piping to be
measured to the HIGH PRESSURE port of the PD-7. Use the tubing and
fittings as shown in FIGURE 1. Use pipe sealant on all threaded pipe
connections.
Complete the tubing connection from the outlet side of the vessel or piping
to be measured to the LOW PRESSURE port of the PD-7. Use the tubing
and fittings as shown in FIGURE 1. Use pipe sealant on all threaded pipe
connections.
MAINTENANCE IS PER THE GAUGE INSTRUCTION SHEET.
