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.
Oil free air must be applied to the regu-
NOTES:
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
systems above and below atmospheric pres-
sure. To increase vacuum or decrease the posi-
tive pressure range, turn the Regulator Knob
counterclockwise. To decrease vacuum or in-
crease 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 atmo-
spheric pressure. In vacuum systems, you can
leave the Supply Port open to atmosphere or
pressurize with normal supply air for faster re-
sponse. For more information, see Figure 3.
