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 MC-COSR outlet and the pipe
flange. Fasten with bolts and nuts.

5. Piping Support
Install the MC-COSR,
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
(for pressure
control)
The length of piping
between the MC-
COSR and 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 flowrate 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.
