I. STEAM INFORMATION
It is your responsibility to have ALL steam plumbing connections made by a qualified professional to assure that
the installation is adequate and conforms to 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
supply of clean, dry, and regulated air 80 PSI +/- 10 PSI (5.51 bars +/- 0.68 bars).
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 ---------2-inch supply line connection
Return ------2-inch return line connection
3. Installation Instructions
To insure that an adequate supply of steam is provided, be sure that the steam supply and steam return lines
are sized and laid out as stipulated in this manual. Inadequate steam supply and steam return lines or
improper steam plumbing will result in poor performance and can cause component failure. Clean, dry, and
regulated steam must be provided to the dryer.
IMPORTANT: Steam coil failure due to water hammer by wet steam will VOID THE WARRANTY.
