H. STEAM INFORMATION
It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the gas plumbing 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: This dryer is manufactured with a pneumatic (piston) damper system, which requires an external supply of clean, dry, regulated air of 0.75 CFH @ 80 PSI +/- 10 PSI (5.51 bars +/-
0.69bars). Refer to Steam DamperAir System Connections, item 4 (page 29).
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.

3.Installation Instructions
To insure an adequate supply of steam is provided, be sure that the steam lines and steam return lines are sized and laid out as stipulated in this manual. Inadequate steam 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.
