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.
