INSTALLATION
You can mount the Model 200 in any position without
affecting its operation. Use the Mounting Bracket,
10311, to mount the booster to any flat surface. For
more information, see Figure 2.
Arrows indicate the Inlet and Outlet ports on the
booster. Tighten all connections securely. Avoid
undersized fittings that will limit the flow through the
booster. For more information, see Figure 1.
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
contaminating the booster. Install the booster in the
air line.
NOTE:
Oil free air must be applied to the booster. Use
a filter to remove dirt and entrained liquid in
the air line ahead of the booster. If an air line
lubricator is used, it MUST be located down-
stream of the booster to avoid interference
with performance.

INSTALLATION OPERATION
If you have the Model 200 with Increased Sensitivity
Option (L), use the Mounting Bracket, 19682-1, to
mount the booster to any flat surface. For more
information, see Figure 4.
For more installation information, see page 1.
The Model 200 reproduces a pneumatic signal in a
1:1 ratio. Apply pressure to the signal chamber until
the required downstream pressure is reached.
This booster is ideally suited for systems that require
input isolation or increased forward flow capacity.
For more information, see Figure 1 and Figure 3.

MAINTENANCE
To clean the Model 200, use the following steps:
1. Shut off system pressure to the booster to prevent air
from escaping. It is not necessary to remove the
booster from the air line.
2. Remove the six screws from the bottom of unit. For
more information, see Figure 5.
3. Remove the Valve Assembly. For more information,
see Figure 5.
4. Wash the Valve Assembly with a solvent. Exercise
care to prevent damage to diaphragms and valve
facings. Avoid solvents such as acetone, carbon
tetrachloride and trichlorethylene.
5. Replace the assembly carefully. Ensure that the
Exhaust Vents in the Spacer Ring are clear. For more
information, see Figure 5.
