TABLE 3

1.

Be sure the entire system is clean
before starting operation to pre-

vent plugging of passages with debris.
The use of strainers or settling tanks in
pipelines leading to the heat exchanger
is recommended. The recommended
strainer size is 20-24 mesh.

Start operating gradually. See
Table 4 for suggested start-up

and shut-down procedures for most
applications. If in doubt, consult the
nearest ITT Heat Transfer representative
for specific instructions.

Do not operate the heat exchanger
under pressure and/or temperature

conditions in excess of the specified
design limits shown on the nameplate
attached to the heat exchanger.

Drain all fluids when shutting down
to eliminate possible freezing and

corroding.

4.

A heat exchanger is a pressure vessel designed for operation at certain specific limits of pressure and temperature. The cooling or process system,
which includes the heat exchanger, must be safeguarded with safety valves and controls so that these heat exchanger design conditions are not
exceeded. All operating personnel should be made aware of these specific design pressures and temperatures.

The nozzle connections are designed
for normal torque force and damage

may occur if over tightened. The use of pipe
sealant materials compatible with the system
fluids is recommended for threaded type
connections. Connection load limits should be
observed and are shown in Figure 2, Table 2,
and Table 3.
