(3) Initial blowdown:
Before commissioning, open the valve
installed immediately before the unit ((1) in
the figure on the right) and blow any scale
out from the piping. This step can be skipped
if scale has already been blown off before
the pipe is connected.
If blowdown has not been adequately carried
out, TLV cannot guarantee against damage
or performance loss of valves and the unit as
a result of scale.
(4) Make sure that the power supply indicator on the control panel is lit and
the power is supplied to the control panel. (Control
panel arrangement may differ from the picture on the
right. The picture on the right is a control panel for
indoor specifications.)
When the power supply indicator is not lit, power may
not be supplied to the control panel. Contact an
electrician. Together with the electrical system manager, investigate the
cause, by checking the wiring, etc.
(5) Check the operation status on the touch panel,
making sure that the operation status is "STOP".
(6) Make sure that steam is supplied up until the steam
inlet valve (No. 9) and the steam pressure does not
exceed 0.6 MPaG, which is the maximum operating
pressure for the unit.
(7) Make sure that the air pressure specified below is supplied to the
positioner of the steam control valve with condensate separator (No. 10).
When the air pressure has not reached the specified value, set the
pressure to the specified value by turning the regulator handle.
(Set pressure: 0.38 MPaG)
For the electric proportional control valve
option, there is no air regulator, therefore this
step is unnecessary.

When adjusting the
air pressure, lift up
the regulator handle
until the orange
sticker is visible,
then turn the handle.
