Fairchild 1600A Installation, Operation And Maintenance Instructions

Installation, Operation and Maintenance Instructions
Figure 1. Model 1600A Outline Dimensions
INSTALLATION
Use the two 1/4-20 tapped holes in the Bonnet to panel
mount the Model 1600A. You can mount the regulator
in any position without affecting its operation.
Clean all pipelines to remove dirt and scale before
installation.
Apply a minimum amount of pipe compound to the
male threads of the fitting only. Do Not use teflon
tape as a sealant. Start with the third thread back and
work away from the end of the fitting to avoid contami­
nating the regulator. Install the regulator in the air line.
The Inlet and Outlet ports are labeled "In" and "Out".
Tighten all connections securely. Avoid undersized
fittings that will limit the flow through the regulator. For
more information, see Figure 1.
NOTES: Oil free air must be applied to the regu­
lator. Use a filter to remove dirt and
entrained liquid in the air line ahead of
the regulator. If an air line lubricator is
used, it MUST be located downstream
of the regulator to avoid interference
with performance.

OPERATION
The Model 1600A controls pressure in high flow sys­
tems above and below atmospheric pressure. To
increase vacuum or decrease the positive pressure
range, turn the Regulator Knob counterclockwise. To
decrease vacuum or increase the positive pressure
range, turn the knob clockwise. For more information,
see Figure 1.
Applications can require a connection for fast evacuation
of a Chamber. For more information, see Figure 2.
Applications can also require a connection to control
system pressure above and below atmospheric pres­
sure. In vacuum systems, you can leave the Supply
Port open to atmosphere or pressurize with normal
supply air for faster response. For more information,
see Figure 3.
