H. STEAM INFORMATION
It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the
steam plumbing installation is adequate and conforms with local and state regulations or codes.
IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in
component failure, which will VOID THE WARRANTY.
NOTE: The dryer is manufactured with a pneumatic (piston) damper system, which requires an
external air supply of 0.75 cfh @ 80 psi +/- 10 psi (0.02 cmh @ 5.51 bar +/- 0.69 bar).
1. Steam Coil PH Level
The normal PH level for copper type steam coils must be maintained between a value of 8.5 to 9.5. For
steel type steam coils the PH level must be maintained between a value of 9.5 to 10.5. These limits are set
to limit the acid attack of the steam coils.
IMPORTANT: Coil failure due to improper PH level will VOID THE WARRANTY.
2. Steam Requirements - High Pressure
Inlet -------- 1” supply line connection -- qty. one (1) at top manifold.
Return ----- 1” return line connection -- qty. one (1) at top manifold.
Shaded areas are stated in metric equivalents
* The minimum operating pressure is 100 psig (689.47 kPa) for optimum results.
3. Installation Instructions
To insure an adequate supply of steam is provided, be sure that the steam supply lines and steam return
lines are sized and laid out as stipulated in this manual. Inadequate steam supply lines and steam return
lines or improper steam plumbing will result in poor performance and can cause component failure. Clean,
dry steam must be provided to the dryer.
IMPORTANT: Steam coil failure due to water hammer by wet steam will VOID THE WARRANTY.
