(1) Steam Inlet Piping
a) Install a pressure gauge at the
steam inlet.
Supply steam pressure range:
0.2 to 0.7 MPaG.
b) Make sure to install piping
support(s) for the steam inlet
piping.
c) Install a valve for emergency shutoff
and maintenance at the steam
inlet.
d) Make sure to install a strainer at
steam inlet.
e) Install a steam trap upstream of the
unit to prevent condensate in the
steam transportation line from
flowing into the unit.
f) When recovering the condensate,
install a check valve on the
secondary side of the steam trap to
prevent backflow.
g) Make sure to insulate the steam
piping as it becomes very hot.
h) When using a pressure reducing
valve to supply steam to the unit, make sure to install a safety valve on the
secondary side of the pressure reducing valve if the pressure on the
primary side of the pressure reducing valve exceeds 0.7 MPaG.
(2) Cold Water Inlet Piping
a) Make sure to install piping
support(s) for the cold water inlet
piping.
b) Install a valve at the cold water inlet
for maintenance. (The valve is
included with the optional
valve/strainer set for the JIS
specification model.)
c) Install a strainer at the cold water
inlet to prevent malfunction of
internal safety functions.
