4. Spacer
Installation
If spacing adjustment is necessary
to accommodate installation, install
a spacer on the outlet flange.
The spacer should consist of a
spacer, gaskets, bolts and nuts. Fit
gaskets to both sides of the spacer
between the
PN-COSR-16
outlet
and the pipe flange. Fasten with
bolts and nuts.

5. Piping
Support
Install the
PN-COSR-16
,
paying attention to avoid
excessive load, bending and
vibration.
Support the inlet and outlet
pipes securely.
6. Maintenance
Space
Leave sufficient space for maintenance, inspection
and repair.

7. Pressure Sensor Installation
(for pressure control)
The length of piping between
the
PN-COSR-16
and the
pressure sensor should be no
more than 5 m (17 ft). If the
piping distance is too great,
pressure loss and delay of
pressure change along this
distance will increase,
resulting in steam flow rate
fluctuations.

Steam fluctuations at the pressure sensor may impair the stability of the
pressure control. Ensure a straight piping run of at least 15 d upstream and
5 d downstream from the pressure sensor.
