For best results, operate with a steam
pressure of 90-125 psi (6.2-8.6 bar). The
steam inlet and return are located on the
right rear of the machine. The inlet is
marked as such and is ¾” NPT (Female).
The return is marked as such and is ½”
NPT (Female).
Important: Insulate all steam and return
lines for the safety of the operator and
service technician.
Important: All steam components must be
rated for a minimum of 200 psi (14 bar)
working pressure. Shut off valves must be
installed upstream of the steam inlet, and
downstream of the steam trap so that the
equipment can be isolated for maintenance
or emergency.
Important: Support all steam lines and
components to minimize the load on the
steam connections to the ironer.
Obtain steam service piping from a steam
system supplier or a qualified steam fitter.
Use a minimum of 12 inch (300mm) rise
above the header to prevent condensate
from draining into the ironer. Do not make
a steam connection to the header with a
horizontal/downward facing tee or elbow.
Wherever possible, horizontal runs of steam
lines must gravity drain to the steam header.
Water pockets or improperly drained
headers will yield poor results due to wet
steam.
Install a union and valve in the steam
supply and return lines for ease of service.
Install an inverted bucket trap with strainer
and a check valve. For best results, install
the trap at least 18 inches (450mm) below
the inlet and as close to the machine as
possible. Install the trap according to the
instructions with the unit, noting the steam
flow direction. If the steam is gravity
returned to the boiler, install a vacuum
breaker and check valve in the return line
near the machine. Note that all return
plumbing must be below the return inlet.
To prevent eventual water hammer, route all
return lines below steam outlets.
